The former CEO of a Conroe wastewater-testing lab, along with two top colleagues, pleaded guilty Thursday in federal court after admitting they doctored lab reports that regulators rely on to judge water safety. Prosecutors say the altered results hid permit exceedances for pollutants including ammonia, E. coli and phosphorus. Sentencing is set for Sept. 3, and each defendant faces up to two years in prison and as much as a $250,000 fine.
In a press release from the U.S. Attorney's Office, Southern District of Texas, prosecutors identified the defendants as Derek McCoy, 52, the lab's former CEO; Deena Higginbotham, 56, director of client services; and John Montgomery, 60, a compliance coordinator. According to the office, the three admitted to falsifying, or aiding and abetting the falsification of, monitoring data that federal and state law requires for wastewater permits. "By submitting falsified data, these defendants undermined the integrity of a program specifically designed to safeguard human health," Acting U.S. Attorney John G.E. Marck said in the release. The office also pushed the announcement out on its social media feed on X.
How Prosecutors Say The Scheme Worked
According to court filings and local reporting, the scheme stretched roughly from 2021 through 2023 and relied on remote-access software and internal databases to change flagged test results before they ever reached regulators. Reporting by the Houston Chronicle detailed dozens of altered readings, including at least 14 high E. coli results and a similar number of elevated microbial activity measurements. Most of the questionable results involved sites in Harris County, with additional instances in Fort Bend, Montgomery, Hays and Comal counties, the outlet noted. Prosecutors say the falsified reports were then submitted to the Environmental Protection Agency and the Texas Commission on Environmental Quality as if the samples met permit limits.
Who Was Put At Risk
Federal prosecutors contend the altered reports masked permit exceedances that, if left uncorrected, could allow inadequately treated effluent to reach bayous and rivers used by Houston-area communities. Local coverage has highlighted that the fraud mostly affected small municipal utility districts that contract out sampling and compliance work, Conroe News reported. Environmental advocates say the case shows how tampering with lab data can undercut the Clean Water Act's protections and erode public trust in the systems that are supposed to keep polluted water out of local waterways.
Legal Consequences And Next Steps
U.S. District Judge David Hittner accepted the guilty pleas and set sentencing for Sept. 3. The pleas expose the defendants to the full statutory penalties tied to the charges they admitted, prosecutors said in the press release. The investigation was led by the EPA Criminal Investigation Division, the EPA Office of Inspector General and the Texas Commission on Environmental Quality's Environmental Crimes Unit, working with the U.S. Attorney's Office. Assistant U.S. Attorney Liesel Roscher and Special Assistant U.S. Attorney Nathan Stopper are prosecuting the case, the office added.
Defense Response And Wider Fallout
McCoy's attorney told reporters his client resigned in February 2024 to "safeguard the laboratory's reputation" and remains hopeful for a favorable resolution, as noted in reporting by the Houston Chronicle. Advocacy groups say the high-profile plea could spur tougher questions about how small utilities pick their testing vendors and whether regulators should add more direct oversight of lab work. Regulators have not issued an immediate public-health advisory tied to the case, but the revelations have already fueled calls for tighter safeguards around sampling and reporting.
The guilty pleas are a relatively rare criminal enforcement move focused on wastewater compliance data, and they serve as a blunt reminder of what can happen when lab numbers are manipulated. Communities downstream, and the agencies that police their water quality, will be watching the Sept. 3 sentencing and any regulatory follow-up that comes in its wake.
