ABOUT PDC LABS

Water Quality Testing & Analysis | Serving Illinois & Missouri Since 1981

Peoria Disposal Company (PDC) was founded by John Coulter in 1928. By 1980, PDC had grown from a one-truck garbage collection operation into a large solid waste hauling and disposal company. In 1983, John Coulter’s grandson, Royal Coulter, became the third generation of Coulters to lead the company. Under Royal’s guidance, PDC realized rapid growth with the acquisition of AREA Disposal Service. From 1989 to 2020, PDC has acquired almost 100 companies located in Illinois and Missouri, which now consist of four landfills, 300 trucks, 4 recycling and processing centers, and a non-hazardous liquid waste treatment plant, PDC and its affiliates make up 15 different companies with over 600 employees.

Water Testing & Analysis

PDC Laboratories was incorporated in 1981 in Peoria, Illinois to provide analytical water quality testing for PDC’s landfills as well as servicing surrounding municipalities and industry. By 1995, the lab was rapidly outgrowing its space and moved into a new 26,000 square-foot, state-of-the art facility on the north side of Peoria. Since then, PDC Laboratories has  acquired five other environmental labs: Daily Analytical Labs (Peoria, IL - 1999),  Katalyst Labs (Peoria, IL - 1999),  Environmetrics (Florissant, MO - 2006), McHenry Analytical (McHenry, IL - 2017), and Prairie Analytical Systems (Springfield, IL - 2018). In 2019, PDC Laboratories built a new 24,000 square-foot, state-of-the-art laboratory in Hazelwood, MO and consolidated its Florissant, MO and Springfield, IL operations into this new location in 2020.

Early in its history, the laboratory was tasked to provide analytical support for other affiliated PDC companies that included a RCRA subtitle C landfill, a non-hazardous wastewater treatment facility, an environmental emergency response team, a remediation company, an environmental engineering firm, and multiple subtitle D landfills. As a result, there are many internal resources available for environmental compliance assistance, regulatory training for staff, and expertise available to our clients.
