Gilbert G. Thomas, Illegal Dumping, IA 2000

Des Moines, IA – Gilbert G. Thomas, owner of Des Moines Septic Tank and Sewer Service (also operating as A-1 Septic Service), was sentenced to a lengthy prison term after pleading guilty to illegally dumping hazardous waste into a tributary of Mud Creek in rural Polk County, Iowa. The case, stemming from persistent complaints of strong fuel odors, exposed a deliberate and ongoing effort to bypass environmental regulations and contaminate local waterways.

The investigation began in late 1998 following numerous reports from residents near Thomas’s property. Authorities discovered an unidentified substance flowing from a pipe originating inside Thomas’s garage, where his septic and waste oil trucks were housed. This pipe discharged directly into the creek, a tributary feeding into Mud Creek. Further investigation revealed a sprawling, unregulated waste storage site owned by Larry Thomas, Gilbert’s associate, containing nine underground storage tanks (USTs) repurposed as above-ground containers for petroleum and other hazardous materials.

On October 1, 1998, Gilbert Thomas was formally charged with eight counts of violating Iowa’s state environmental statutes. Larry Thomas faced a single count related to the illegal storage of hazardous waste. The evidence quickly mounted, demonstrating a pattern of intentional dumping of septic tank sludge, petroleum products, and other prohibited materials. Investigators determined that Thomas had been systematically discharging waste directly into the creek, avoiding the costs and regulations associated with proper disposal.

The legal proceedings culminated in guilty pleas from both men. Larry Thomas pleaded guilty on January 27, 1999, and received a sentence of 24 months incarceration followed by 24 months of probation. No fine was levied against him. Gilbert Thomas, however, faced a far more substantial penalty. On August 9, 1999, he admitted guilt to all eight counts. On October 22, 1999, he was sentenced to a staggering 120 months (10 years) in prison. In addition to his incarceration, Thomas was ordered to pay $45,903 in restitution to cover environmental remediation costs and a hefty state fine of $130,000.
