I am a municipal water quality technician who runs the environmental lab for the city, and when I looked at the state compliance report, I realized my director had erased the lead contamination readings from a public school so he wouldn’t have to pay to replace their pipes.

I am a municipal water quality technician who runs the environmental lab for the city, and when I looked at the state compliance report, I realized my director had erased the lead contamination readings from a public school so he wouldn’t have to pay to replace their pipes.

My name is Cheryl Fuentes.

I am a municipal water quality technician.

Wayne Holt altered a PDF compliance report to hide lead in a public school’s drinking water.

He did not know how to delete the atomic mass signatures from the spectrometer’s hard drive.

He changed the PDF.

He did not change the spectrometer.

I run the City of Mossbluff municipal water quality laboratory out of a thirty-six-hundred-square-foot bench-equipped lab on the ground floor of the City Utilities Department’s central operations building on the west side of the city.

I am the only full-time technician at the lab.

I report to the City Utilities Director Wayne Holt, who reports to the city manager.

I am a state-certified water quality analyst, a state-certified environmental sampling technician, and a state-certified mass spectrometry operator on the lab’s bench-top inductively coupled plasma mass spectrometer.

I have run the lab for the past eleven years.

I came in to the lab at six forty-five on a Wednesday morning to start the day’s analytical run.

The day’s analytical run was scheduled to process the prior week’s compliance sample batch from approximately forty municipal sampling points across the City of Mossbluff’s potable water system.

I powered up the inductively coupled plasma mass spectrometer at six fifty.

I ran the morning calibration sequence on the spectrometer.

The morning calibration sequence consisted of a blank-blank run on deionized water followed by a five-point standard curve using known lead concentrations of one, five, fifteen, fifty, and one hundred parts per billion.

The blank-blank run returned a lead detection at zero point zero zero two parts per billion against an instrument noise floor of approximately zero point zero zero one parts per billion.

The five-point standard curve returned a linear regression coefficient of zero point nine nine nine two against the target of zero point nine nine nine zero.

The five-point standard curve also showed a zero point zero five percent drift on the fifty parts per billion standard against the prior morning’s calibration.

I stopped the spectrometer.

I shut down the plasma torch.

I unscrewed the nebulizer tip from the sample introduction port.

I cleaned the nebulizer tip in a five percent nitric acid bath for ten minutes.

I rinsed the nebulizer tip in three sequential rinses of laboratory-grade deionized water.

I dried the nebulizer tip with a stream of zero-grade argon gas.

I reinstalled the nebulizer tip on the sample introduction port.

I powered the plasma torch back on at seven twenty-two.

I waited for the plasma torch to stabilize at the operating temperature of approximately six thousand degrees Celsius.

I reran the morning calibration sequence at seven thirty-three.

The blank-blank run returned a lead detection at zero point zero zero one parts per billion.

The five-point standard curve returned a linear regression coefficient of zero point nine nine nine five.

The drift was within the lab’s quality assurance protocol’s acceptance criterion of less than zero point zero two percent.

I cleared the calibration sequence on the spectrometer.

I loaded the prior week’s compliance sample batch into the spectrometer’s auto-sampler.

The auto-sampler held the prior week’s compliance samples in a two-tray-by-twenty-sample rack with the samples arranged by sample identification number.

I started the analytical run at seven forty-seven Wednesday morning.

The analytical run was scheduled to complete at approximately ten thirty Wednesday morning across the forty samples at approximately four minutes per sample including the inter-sample rinse cycle.

I had drawn the prior week’s compliance samples in the field on the prior Tuesday.

The prior Tuesday’s field sample collection had included routine compliance samples from the city’s six standpipes, four well-houses, fourteen distribution-system flush points, and sixteen end-user sampling points.

The sixteen end-user sampling points included four sampling points at the McKinley Middle School on the south side of the city, a kindergarten-through-eighth-grade public school of approximately seven hundred students located in a low-income residential district.

The four McKinley Middle School sampling points were the drinking fountain in the south corridor of the academic wing, the drinking fountain outside the gymnasium, the kitchen prep-sink in the cafeteria, and the locker-room handwashing sink in the boys’ locker room.

I had drawn the four samples at the four sampling points on the prior Tuesday morning between nine and ten fifteen using the lab’s standard chain-of-custody protocol.

I had worn nitrile gloves.

I had filled a two-hundred-and-fifty-milliliter Nalgene bottle at each sampling point after flushing the line for approximately ninety seconds at each point.

I had immediately added two milliliters of trace-metal-grade nitric acid preservative to each bottle.

I had labeled each bottle with the sampling point identifier, the date and time of sample collection, my initials, and a unique sample identification number on a pre-printed barcode label.

I had logged the cooler temperature at each sampling point with a calibrated thermocouple.

I had transported the samples back to the lab in a refrigerated transport cooler at four degrees Celsius.

I had drawn a duplicate two-hundred-and-fifty-milliliter Nalgene B-sample at each of the four McKinley Middle School sampling points under the lab’s standard duplicate-sample protocol.

I had labeled each B-sample with the same sampling point identifier, the same date and time of sample collection, my initials, and a unique sample identification number on a pre-printed barcode label.

I had logged each B-sample into the lab’s chain-of-custody log.

I had stored each B-sample in the lab’s secured refrigerated B-sample storage cooler in the storage room behind the lab.

The B-sample storage cooler was a locked refrigerated cooler with a four-degree-Celsius set point.

The B-sample storage cooler held the lab’s full set of duplicate B-samples for the current and prior twelve months of compliance sampling.

The B-sample storage cooler’s key was on my keychain.

The spectrometer’s analytical run finished at ten thirty-three Wednesday morning.

I reviewed the analytical run’s raw output on the spectrometer’s bench-top monitor.

The analytical run’s raw output included a chromatographic trace for each sample showing the detector counts per second on the lead mass-channel of two hundred and eight atomic mass units against the run-time elapsed across the sample-introduction window.

Sample identification number forty-four-oh-nine, which was the south-corridor drinking fountain at McKinley Middle School, returned a lead concentration of forty-two point one parts per billion against an EPA action level of fifteen parts per billion.

Sample identification number forty-four-eleven, which was the gymnasium drinking fountain, returned a lead concentration of thirty-seven point four parts per billion.

Sample identification number forty-four-thirteen, which was the cafeteria kitchen prep-sink, returned a lead concentration of twenty-eight point nine parts per billion.

Sample identification number forty-four-fifteen, which was the boys’ locker-room handwashing sink, returned a lead concentration of fifty-three point six parts per billion.

A PDF report is just a piece of paper.

The spectrometer’s hard drive writes lines of code that record exactly how many atoms of lead hit the detector at exactly what millisecond.

The drive has no edit button.

I exported the four McKinley Middle School samples’ raw analytical output to a single .csv file at ten thirty-seven Wednesday morning.

The .csv file recorded for each sample the spectrometer’s internal sequence number, the auto-sampler tray position, the sample identification number, the operator (me) by login token, the calibration validation record, the run-time start and end timestamps to the nearest millisecond, the detector counts per second on the lead mass-channel of two hundred and eight atomic mass units in five-millisecond bins across the sample-introduction window, the integrated peak area, the calculated concentration in parts per billion, and the internal-standard recovery confirmation.

The .csv file’s filename was generated by the spectrometer software from the date, the operator login, and the run sequence number, in the format that the lab’s quality assurance protocol required.

The .csv file was saved on the spectrometer’s internal hard drive in the protected raw-data directory.

The protected raw-data directory was a write-once partition of the spectrometer’s internal hard drive that the lab’s quality assurance protocol required for compliance with the state Department of Health’s water-quality analytical chain-of-custody standard.

The write-once partition did not allow modification, deletion, or overwrite of any file once written.

The write-once partition allowed read-only access to the .csv files for export.

I exported a copy of the .csv file to the lab’s general data server at ten thirty-nine Wednesday morning under the standard analytical-data-export filename convention.

I closed the analytical run.

I sat at the lab bench.

I drafted the standard analytical-results summary on the lab’s word-processing template.

The standard analytical-results summary listed the four McKinley Middle School sample concentrations in tabular format with the EPA action level of fifteen parts per billion in the right-hand column for reference.

I printed two copies of the standard analytical-results summary.

I walked the first paper copy to the City Utilities Director Wayne Holt’s office on the second floor of the City Utilities Department’s central operations building.

Wayne Holt was at his desk.

Wayne Holt was working through the prior month’s vendor invoices on a stack of paper on the right side of the desk.

I handed Wayne Holt the standard analytical-results summary.

I summarized the four McKinley Middle School sample concentrations.

I told Wayne Holt the south-corridor drinking fountain was at forty-two point one parts per billion.

I told Wayne Holt the gymnasium drinking fountain was at thirty-seven point four parts per billion.

I told Wayne Holt the cafeteria kitchen prep-sink was at twenty-eight point nine parts per billion.

I told Wayne Holt the boys’ locker-room handwashing sink was at fifty-three point six parts per billion.

Wayne Holt looked at the standard analytical-results summary.

Wayne Holt set the standard analytical-results summary on the right side of the desk on top of the prior month’s vendor invoices.

Wayne Holt said, Cheryl.

Wayne Holt said, just upload the raw data to the server.

Wayne Holt said, I will compile the state submission this afternoon.

Wayne Holt said, thank you for the diligent work.

I returned to the lab.

I sat at the lab bench.

I kept the second paper copy of the standard analytical-results summary in the lab’s printed-results filing cabinet under the McKinley Middle School folder.

I worked through the remaining samples in the prior week’s compliance sample batch across the rest of Wednesday afternoon.

I came in to the lab at six forty-five Thursday morning to start the next day’s analytical run.

I walked past the administrative office’s shared copier on the way to the lab.

The shared copier had a stack of approximately twenty pages in the output tray.

The output tray’s top page was a printed copy of the city’s monthly state compliance report for the prior compliance sample batch.

The state compliance report was the document that the city was required to transmit to the state Department of Health’s environmental water quality compliance section on the first business day of each month.

The state compliance report listed each sample identification number, the sampling point, and the sample concentration in parts per billion.

I picked up the top page.

I scanned the McKinley Middle School sampling points on the table.

The south-corridor drinking fountain on sample identification number forty-four-oh-nine listed a concentration of twelve point one parts per billion.

The gymnasium drinking fountain on sample identification number forty-four-eleven listed a concentration of seven point four parts per billion.

The cafeteria kitchen prep-sink on sample identification number forty-four-thirteen listed a concentration of eight point nine parts per billion.

The boys’ locker-room handwashing sink on sample identification number forty-four-fifteen listed a concentration of thirteen point six parts per billion.

I remembered seeing a four in the tens column when the spectrometer monitor had shown forty-two point one parts per billion on sample identification number forty-four-oh-nine the prior morning.

I read the state compliance report’s signature page at the back of the stack.

The signature page carried Wayne Holt’s signature on the City Utilities Director line, dated the prior Wednesday afternoon, three hours after the spectrometer analytical run had finished.

I put the printed copy of the state compliance report back on the output tray of the copier.

I returned to the lab.

I sat at the lab bench.

I held the prior day’s standard analytical-results summary that I had filed in the printed-results filing cabinet in my right hand.

I opened the spectrometer’s protected raw-data directory on the bench-top monitor in my left hand on the keyboard.

I opened the .csv file for the prior day’s McKinley Middle School samples.

The .csv file’s sample identification number forty-four-oh-nine recorded a concentration of forty-two point one parts per billion.

The .csv file’s sample identification number forty-four-eleven recorded a concentration of thirty-seven point four parts per billion.

The .csv file’s sample identification number forty-four-thirteen recorded a concentration of twenty-eight point nine parts per billion.

The .csv file’s sample identification number forty-four-fifteen recorded a concentration of fifty-three point six parts per billion.

The .csv file recorded the operator login token as my login token.

The .csv file recorded the run-time start and end timestamps on the prior Wednesday morning.

The .csv file recorded the calibration validation record as the morning’s recalibration after the nebulizer-tip cleaning.

The .csv file recorded the internal-standard recovery confirmation as within the lab’s quality assurance protocol’s acceptance criterion.

The .csv file was the raw output from the spectrometer’s hard drive.

The .csv file was the truth.

I closed the .csv file.

I locked the lab bench workstation.

I walked to the storage room behind the lab.

I unlocked the B-sample storage cooler with the key on my keychain.

I located the four McKinley Middle School B-samples on the second shelf of the cooler.

The four B-samples were the same Nalgene bottles I had labeled at the four McKinley Middle School sampling points on the prior Tuesday morning.

The four B-samples were sealed.

The four B-samples were at four degrees Celsius.

The four B-samples held two hundred and fifty milliliters of clear water with two milliliters of trace-metal-grade nitric acid preservative.

The four B-samples did not look toxic.

The four B-samples did not look like a crime.

The clarity was the corruption.

I locked the B-sample storage cooler.

I walked back to the lab bench.

I sat at the bench.

I held the prior day’s standard analytical-results summary in my right hand.

I held the printed copy of the state compliance report’s McKinley Middle School row in my left hand.

I did not walk to Wayne Holt’s office.

I sat at the lab bench.

I drafted an emergency complaint on the lab’s word-processing template addressed to the United States Environmental Protection Agency Region Nine Enforcement Office and the state Department of Health environmental water quality compliance section.

The emergency complaint summarized the spectrometer’s raw analytical output, the standard analytical-results summary, the state compliance report, the variance between the two, the chain-of-custody record on the four McKinley Middle School samples, and the existence of the four sealed B-samples in the lab’s secured refrigerated storage cooler.

The emergency complaint requested an emergency Do-Not-Drink order for the McKinley Middle School potable water system and a federal-state joint criminal investigation of the falsification of the state compliance report.

The emergency complaint identified Wayne Holt by name as the signatory on the falsified state compliance report.

The emergency complaint identified me by name and title as the analytical technician.

The emergency complaint attached the .csv file, the standard analytical-results summary, the photographed page of the state compliance report, the lab’s chain-of-custody log for the four McKinley Middle School samples, and the B-sample storage cooler inventory log.

I signed the emergency complaint at eight forty-two Thursday morning.

I sent the emergency complaint by encrypted email at eight forty-six Thursday morning to the EPA Region Nine intake channel and the state Department of Health intake channel.

I received automated confirmation receipts from both intake channels within fifteen minutes.

I did not copy Wayne Holt.

The City Council’s quarterly infrastructure meeting was held in the city hall council chamber at seven Tuesday evening, six business days after I had sent the emergency complaint to the EPA Region Nine Enforcement Office and the state Department of Health.

The city hall council chamber held a raised semicircular dais for the seven-member City Council at the north end of the room, a long staff table on the floor below the dais facing the public, a public podium with a microphone in the center of the room facing the dais, and approximately one hundred and forty folding chairs in the public gallery.

The public gallery was approximately half full.

The City Utilities Director Wayne Holt was at the staff table at the floor below the dais.

Wayne Holt was set to present the City Utilities Department’s Clean Water Initiative update as the second agenda item of the quarterly meeting.

The Clean Water Initiative update included a slide presentation on the city’s compliance with the EPA’s lead-and-copper rule across the prior fiscal year.

The Clean Water Initiative update was scheduled to recommend the City Council renew the city’s annual water safety certification for the coming fiscal year on the consent agenda of the following Tuesday’s regular City Council meeting.

I parked the lab’s refrigerated transport cooler on a small rolling cart at the back of the public gallery at six fifty-five.

The refrigerated transport cooler held the four McKinley Middle School B-samples on ice packs at four degrees Celsius.

The refrigerated transport cooler also held a manila folder with the .csv file printed at the lab’s bench-top printer, the prior day’s standard analytical-results summary, the photographed page of the state compliance report, and the chain-of-custody log for the four McKinley Middle School samples.

I sat in the back row of the public gallery beside the rolling cart.

The City Council chair gaveled the meeting to order at seven oh-five.

The City Council chair walked through the consent agenda in approximately twelve minutes.

The consent agenda passed seven to zero.

The City Council chair recognized Wayne Holt for the City Utilities Department’s Clean Water Initiative update.

Wayne Holt walked to the public podium.

Wayne Holt walked through the Clean Water Initiative slide presentation for approximately fourteen minutes.

Wayne Holt presented the city’s compliance status across the city’s approximately one hundred and seventy compliance sampling points across the prior fiscal year.

Wayne Holt highlighted the McKinley Middle School compliance status as a success case for the Clean Water Initiative.

Wayne Holt cited the four McKinley Middle School sampling points’ compliance with the EPA’s fifteen-parts-per-billion lead action level.

Wayne Holt recommended the City Council renew the city’s annual water safety certification on the consent agenda of the following Tuesday’s regular meeting.

The City Council chair thanked Wayne Holt.

The City Council chair opened the public comment period on the Clean Water Initiative agenda item.

The City Council chair called the first speaker, a resident of the McKinley Middle School neighborhood, who spoke for three minutes about the neighborhood’s general concerns about water infrastructure aging in the low-income residential district.

The City Council chair called the second speaker, a representative of the McKinley Middle School parent-teacher organization, who spoke for three minutes about the parent-teacher organization’s request for additional state grant funding for school facilities.

The City Council chair called my name as the third speaker.

I stood up from the back row.

I pulled the rolling cart with the refrigerated transport cooler along the center aisle to the public podium.

I positioned the rolling cart beside the public podium.

I leaned forward into the microphone.

I said, Mr. Chair, council members, my name is Cheryl Fuentes.

I said, I am the City of Mossbluff’s municipal water quality technician at the City Utilities Department’s environmental analytical laboratory.

I said, I am addressing the council this evening in my capacity as the analytical technician responsible for the compliance sample analysis on the four McKinley Middle School sampling points that Director Holt referenced in his presentation.

I opened the manila folder from the refrigerated transport cooler.

I distributed twelve copies of the .csv file’s first page to the front-row council staff table and to the side-aisle gallery row at the front for hand-passing across the chamber.

I distributed twelve copies of the standard analytical-results summary to the same rows.

I distributed twelve copies of the photographed page of the state compliance report to the same rows.

The paper passed across the rows behind me as I stood at the public podium.

I opened the refrigerated transport cooler.

I lifted the four McKinley Middle School B-sample Nalgene bottles out of the cooler.

I set the four Nalgene bottles on the public podium in a row.

The four Nalgene bottles were sealed.

The four Nalgene bottles held clear water.

I leaned back into the microphone.

I said, Director Holt presented the McKinley Middle School compliance status as a success case.

I said, Director Holt’s presentation cited the state compliance report on the four McKinley Middle School sampling points as showing concentrations of twelve point one parts per billion, seven point four parts per billion, eight point nine parts per billion, and thirteen point six parts per billion.

I said, the spectrometer’s raw analytical output on the same four sampling points recorded concentrations of forty-two point one parts per billion, thirty-seven point four parts per billion, twenty-eight point nine parts per billion, and fifty-three point six parts per billion.

I said, the spectrometer’s raw analytical output is on the .csv file at page one of the .csv file printout I have distributed to the front-row council staff table and to the side-aisle gallery row.

I said, the standard analytical-results summary that I prepared on Wednesday morning, and that I personally delivered to Director Holt’s office on Wednesday morning, recorded the same four concentrations from the .csv file.

I said, the standard analytical-results summary is on the second copy I have distributed.

I said, the state compliance report that Director Holt signed Wednesday afternoon and transmitted to the state Department of Health on Friday morning is on the third copy I have distributed.

I said, the state compliance report’s signature page carries Director Holt’s signature on the City Utilities Director line.

I lifted the four Nalgene bottles slightly off the podium one at a time as I read each sample identification number.

I said, the four McKinley Middle School B-sample Nalgene bottles I am holding on the public podium are the duplicate samples I drew at the same four sampling points on the Tuesday morning prior to the spectrometer analytical run.

I said, the four B-samples are sealed in the same Nalgene bottles I labeled at the four sampling points.

I said, the four B-samples are at four degrees Celsius from the refrigerated transport cooler.

I said, the four B-samples have been in the lab’s secured refrigerated storage cooler since I drew them on the Tuesday morning of the field sample collection.

I said, the four B-samples are available for any independent laboratory to re-test on the standard EPA reference method for lead analysis.

I said, the four B-samples will return the same concentrations as the .csv file on any independent laboratory’s spectrometer because the four B-samples are the duplicate water.

I said, Director Holt did not change the water.

I said, Director Holt changed the PDF.

I said, the EPA Region Nine Enforcement Office and the state Department of Health environmental water quality compliance section have an emergency complaint I filed by encrypted email on the Thursday morning after the spectrometer analytical run.

I said, the EPA and the state Department of Health have the .csv file, the standard analytical-results summary, the photographed state compliance report, the chain-of-custody log, and the B-sample storage cooler inventory log.

I said, you should expect a Do-Not-Drink order from the state Department of Health on the McKinley Middle School potable water system before the close of business this week.

I stepped back from the public podium.

The chamber was quiet for a count of approximately four seconds.

Wayne Holt stood up from the staff table.

Wayne Holt walked out of the chamber through the side door without addressing the dais.

Wayne Holt did not return.

The City Council chair recessed the Clean Water Initiative agenda item.

The City Council chair recessed the meeting at seven forty-three.

The state Department of Health issued an emergency Do-Not-Drink order on the McKinley Middle School potable water system at four oh-eight the following Thursday afternoon.

The state Department of Health and the EPA Region Nine Enforcement Office opened a joint criminal investigation into the falsification of the state compliance report at nine the following Friday morning.

The state attorney general’s office opened a parallel state criminal investigation at nine that same Friday morning.

The federal grand jury indicted Wayne Holt on three counts of falsification of environmental compliance records and one count of obstruction of an environmental investigation approximately seventeen weeks after the City Council meeting.

Wayne Holt resigned the City Utilities Director position on the morning the federal indictment was unsealed.

Wayne Holt pled guilty to a single count of falsification of environmental compliance records approximately nine months after the indictment.

Wayne Holt served eighteen months in a federal correctional facility.

Wayne Holt was barred from holding any municipal utilities oversight position in the state for fifteen years as a condition of the plea.

The state Department of Health’s emergency Do-Not-Drink order on the McKinley Middle School potable water system was lifted approximately seven weeks after the City Council meeting.

The seven weeks between the spectrometer analytical run on the Wednesday of the field sample analysis and the lifting of the Do-Not-Drink order on the McKinley Middle School potable water system were the seven weeks during which the school’s approximately seven hundred kindergarten-through-eighth-grade students continued to drink from the four sampling points on the school’s potable water system.

The state Department of Health provided emergency bottled water service to the McKinley Middle School beginning on the Friday morning after the Do-Not-Drink order was issued.

The emergency bottled water service was a state-contracted vendor delivery of approximately three thousand individual five-hundred-milliliter bottled-water units to the school per week across the seven weeks of the Do-Not-Drink order.

The emergency bottled water service was also extended on the same delivery schedule to the residential households on the same potable water service line as the McKinley Middle School across the low-income residential district on the south side of the city.

The residential households on the same potable water service line numbered approximately eight hundred and forty single-family households and approximately two hundred and twenty multi-family units across three apartment buildings.

The state Department of Health’s water quality field laboratory drew an additional set of compliance samples across the McKinley Middle School and the surrounding residential households on the same potable water service line in the second week of the Do-Not-Drink order.

The state’s compliance samples returned an average lead concentration of approximately twenty-one point eight parts per billion across forty additional sampling points in the school and the surrounding residential district.

The state’s compliance samples returned a single high-end reading of one hundred and twelve parts per billion at the kitchen-sink tap of a single-family residence on Fairmount Avenue approximately two blocks south of the school.

The state’s compliance samples confirmed the spectrometer’s raw analytical output from the lab’s prior week’s compliance sample batch as accurate.

The state’s compliance samples confirmed the variance between the spectrometer’s raw analytical output and the state compliance report on the four McKinley Middle School sampling points as the falsification at issue.

The state’s compliance samples confirmed the contamination was systemic across the potable water service line and not limited to the school.

The City of Mossbluff’s emergency lead service line replacement program was launched approximately six weeks after the lifting of the Do-Not-Drink order.

The emergency lead service line replacement program was funded by an EPA Drinking Water State Revolving Fund emergency grant of approximately twenty-three million dollars supplemented by a state Department of Health emergency infrastructure grant of approximately seven million dollars.

The emergency lead service line replacement program replaced approximately one thousand four hundred and seventy lead service lines across the McKinley Middle School potable water service line and the surrounding low-income residential district across the following twenty-two months.

The state Department of Health’s emergency lead exposure remediation program enrolled approximately three thousand two hundred children under age six from the affected residential district for free in-home blood lead level testing across the same twenty-two months.

The free in-home blood lead level testing identified approximately one hundred and forty children under age six with elevated blood lead levels above the federal Centers for Disease Control reference level of three point five micrograms per deciliter.

The one hundred and forty children with elevated blood lead levels were enrolled in a state-funded individualized exposure remediation case management program that included repeated blood lead level monitoring, in-home environmental assessment, parental education, and a small remediation stipend for in-home water filtration equipment.

The seven weeks during which the McKinley Middle School students had continued to drink from the four sampling points on the potable water system were the seven weeks that the lead service line replacement program could not undo.

Lead exposure on a developing pediatric central nervous system is cumulative.

Lead exposure on a developing pediatric central nervous system is irreversible.

The seven weeks were the seven weeks.

The seven weeks were the residue.

The seven weeks were the cost of the prior six business days between my email to the EPA Region Nine Enforcement Office and the state Department of Health on the Thursday morning after the spectrometer analytical run, and the public City Council meeting on the Tuesday evening at which I read the .csv file’s concentrations into the public record.

The six business days were the six business days that the EPA Region Nine Enforcement Office and the state Department of Health had been processing the emergency complaint without taking the field-action step that the public City Council meeting forced into the open.

The six business days were the six business days that I had not pushed harder for an emergency Do-Not-Drink order on the school in the gap.

The six business days were the six business days that I had instead allowed the EPA Region Nine and the state Department of Health to follow their standard intake-and-review process.

The six business days were a decision.

The decision was the decision.

The decision was wrong.

The decision was the decision I will live with.

The decision was the residue I will carry across the rest of my career as a municipal water quality technician.

The decision will be a different decision the next time I have an emergency complaint to file with the EPA Region Nine Enforcement Office and the state Department of Health environmental water quality compliance section.

The next decision will not be to wait six business days for the EPA and the state to follow the standard intake-and-review process.

The next decision will be to file the emergency complaint, then drive directly to the affected facility, then file a parallel complaint with the state attorney general’s office, then attend the next public meeting of the affected jurisdiction with the physical B-samples, the raw .csv files, and the chain-of-custody logs.

The next decision will compress the six business days into a single business day.

The next decision is the decision I have already made for the next time.

The next time has not arrived.

The seven weeks have not been undone.

I have been the City of Mossbluff’s municipal water quality technician at the City Utilities Department’s environmental analytical laboratory for the past eleven years.

I have been the City of Mossbluff’s municipal water quality technician at the City Utilities Department’s environmental analytical laboratory across the seven weeks of the McKinley Middle School Do-Not-Drink order, the federal indictment of the former City Utilities Director Wayne Holt, the federal plea acceptance, the federal sentencing, the state plea agreement, the state probation, the EPA Drinking Water State Revolving Fund emergency grant, the state Department of Health emergency infrastructure grant, the emergency lead service line replacement program, the state-funded individualized exposure remediation case management program, the appointment of a new City Utilities Director, the new City Utilities Director’s reorganization of the City Utilities Department, the new City Utilities Director’s reaffirmation of the lab’s chain-of-custody protocol, and the city manager’s transmittal of a public-facing statement of commitment to the McKinley Middle School community on the front page of the city’s quarterly newsletter.

The newsletter is the newsletter.

The newsletter does not undo the seven weeks.

The newsletter is on the cork board in the lab’s break room.

I look at the newsletter on the cork board sometimes at the lab’s break-room sink at the end of the day.

I do not read the newsletter.

The newsletter is on the cork board.

The newsletter is the residue.

The work held.

The work did not hold fast enough.

The work held the way the work held.

I sit at the lab bench at the City Utilities Department’s environmental analytical laboratory on a Wednesday morning in the eighth month after the lifting of the Do-Not-Drink order.

The lab is the lab.

The bench is the bench.

The spectrometer is the spectrometer.

The B-sample storage cooler is the B-sample storage cooler.

The key to the B-sample storage cooler is on my keychain.

The B-sample storage cooler holds the lab’s full set of duplicate B-samples for the current and prior twelve months of compliance sampling.

The B-sample storage cooler holds the four McKinley Middle School B-samples I drew at the four sampling points on the Tuesday morning of the field sample collection before the seven weeks.

The four B-samples sit on the second shelf of the cooler in a small acrylic rack labeled MCKINLEY-EVIDENCE-RETAIN at the back of the rack.

The four B-samples are evidence in the federal case.

The four B-samples will sit in the rack until the federal case’s evidentiary retention period ends approximately four years after the close of the federal sentencing.

The four B-samples will sit in the rack for four years.

The four B-samples are the four B-samples.

The four B-samples are the lab’s work.

The work held.

The work did not hold fast enough.

The work is the work.

I run the spectrometer’s morning calibration sequence at six fifty Wednesday morning.

The blank-blank returns zero point zero zero one parts per billion against an instrument noise floor of approximately zero point zero zero one parts per billion.

The five-point standard curve returns a linear regression coefficient of zero point nine nine nine four.

The drift is within the lab’s quality assurance protocol’s acceptance criterion.

I load the prior week’s compliance sample batch into the auto-sampler.

I start the analytical run at seven forty Wednesday morning.

I sit at the lab bench across the run.

I review the raw output on the bench-top monitor.

I export the .csv file to the protected raw-data directory at the close of the run.

I export a copy of the .csv file to the lab’s general data server.

I draft the standard analytical-results summary on the lab’s word-processing template.

I print two copies of the standard analytical-results summary.

I walk the first paper copy to the new City Utilities Director’s office on the second floor of the City Utilities Department’s central operations building.

The new City Utilities Director is a woman named Joanne Pemberton-Doyle.

Joanne Pemberton-Doyle is at her desk.

Joanne Pemberton-Doyle is working through the city’s annual capital improvement budget on a stack of paper on the right side of the desk.

I hand Joanne Pemberton-Doyle the standard analytical-results summary.

I summarize the prior week’s compliance sample batch results.

Joanne Pemberton-Doyle reads through the table.

Joanne Pemberton-Doyle thanks me.

Joanne Pemberton-Doyle says, Cheryl.

Joanne Pemberton-Doyle says, please also send the .csv file directly to the state Department of Health under our new standing chain-of-custody protocol.

I tell Joanne Pemberton-Doyle I have already sent the .csv file directly to the state Department of Health.

Joanne Pemberton-Doyle nods.

I return to the lab.

I keep the second paper copy of the standard analytical-results summary in the lab’s printed-results filing cabinet under the appropriate week’s folder.

I sit at the lab bench.

I review the next week’s field sample collection schedule.

The next week’s field sample collection includes a routine quarterly sample at the McKinley Middle School south-corridor drinking fountain.

The routine quarterly sample is the routine quarterly sample.

The routine quarterly sample is the work.

The work is the work.

The work holds.

The seven weeks were the seven weeks.

The seven weeks are not the work.

The seven weeks are the residue.

The work goes on.

The work holds.
