Gilbert G. Thomas, Environmental Crime, 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 significant prison term following a lengthy investigation into illegal waste disposal practices. The case, originating from complaints of noxious fuel odors near Mud Creek in rural Polk County, revealed a deliberate and sustained effort to bypass environmental regulations and endanger local waterways.

The investigation, sparked in late 1998, quickly focused on Thomas’ property where authorities discovered an unidentified substance flowing directly into a tributary of Mud Creek via a pipe originating from his garage. This garage served as the parking location for Thomas’ vacuum and pumper trucks, used in the business of septic tank sludge and waste oil removal. Further scrutiny revealed the operation wasn’t limited to direct discharge; authorities also investigated a waste storage site owned by Larry Thomas, Gilbert’s associate, which housed nine underground storage tanks (USTs) repurposed for the storage of petroleum and hazardous waste – all operating outside of legal guidelines.

According to court documents, Gilbert Thomas was initially charged with eight counts of violating Iowa State environmental statutes on October 1, 1998. Larry Thomas faced a single charge relating to the improper storage of hazardous materials. The evidence presented painted a picture of a calculated disregard for environmental protection, with Thomas allegedly directing the illegal dumping of septic tank sludge, petroleum products, and other potentially harmful substances directly into the creek, avoiding the costs associated with proper disposal.

The legal proceedings culminated in guilty pleas from both men. Larry Thomas admitted to his role in the improper storage and was sentenced to 24 months incarceration, followed by 24 months of probation. No fine was levied against him. However, the bulk of the penalty fell upon Gilbert Thomas, who pleaded guilty to all eight counts against him on August 9, 1999. On October 22, 1999, Thomas received a 120-month (10 year) prison sentence, a $130,000 state fine, and was ordered to pay $45,903 in restitution to cover the costs of environmental remediation.
