The laboratory performs analyses of drinking, surface and ground water samples, as well as wastewater influent and effluent, sediment, soil, sludge, manure, air filter, air canister, and fish, turtle and plant tissue samples.
Analyses include testing for inorganic pollutants, such as mercury, cyanide, arsenic, cadmium, lead, oil and grease and ammonia; microbiological constituents, such as E.coli.; and organic contaminants such as pesticides, herbicides, polychlorinated biphenyls (PCBs) and volatile organic compounds (VOCs). In addition, the laboratory conducts toxicity studies of wastewater effluents and sediments on aquatic organisms.
Through these efforts, Ohio EPA identifies sources of known environmental problems and reveals other pollution that might otherwise go undetected. Ohio EPA can then develop permits and management solutions to achieve environmental benefits in a cost-effective manner. This monitoring also measures progress toward achieving compliance with environmental laws and standards and provides information on what pollution control strategies are most effective.
The fish tissue analyses conducted by the lab form the basis of the state’s annual fish consumption advisory. Since this program began in 1994, more than 6,000 sport fish tissue samples have been tested.
All drinking water laboratories in Ohio are inspected and certified by Ohio EPA’s lab staff to ensure they have proper equipment and facilities as well as trained staff employing proper analytical techniques. The overall goal is to ensure the safety of water obtained from public water systems.
Finally, lab employees provide training and technical assistance within and outside Ohio EPA regarding analytical methods and sampling requirements.
The Laboratory Certification and Assistance program includes the drinking water laboratory certification program. In addition, the division conducts performance audit inspections of laboratories for wastewater discharge (NPDES) permitting purposes and provides training and technical assistance within and outside Ohio EPA.
The Ohio EPA Drinking Water Laboratory Certification Program is managed by two divisions within Ohio EPA. The Division of Environmental Services (DES) is responsible for operation of the program. The Division of Drinking and Ground Waters administers the program and issues laboratory certificates. All drinking water laboratories in Ohio are inspected and certified by DES staff as having proper equipment and facilities as well as trained staff employing proper analytical techniques in order to ensure the safety of water obtained from public water systems. Laboratory certification documents such as applications, manuals, newsletters and construction/remodeling information are available on the Division of Drinking and Ground Water Laboratory Certification (DDAGW) web page.
U.S. EPA's Annual Discharge Monitoring Report - Quality Assurance (DMR-QA) provides a proficiency testing program for wastewater laboratories in Ohio. Based on the results of annual DMR-QA testing, as well as requests from the Division of Surface Water, the laboratory conducts performance audit inspections (PAIs) of wastewater testing laboratories used by the regulated community.

Acceptable Corrective Action Procedures
If any graded results are "Not Acceptable," the permittee must follow up with the laboratory to determine the cause of the deficiency and ensure corrective action is taken to prevent future occurrences. The laboratory must order retesting samples for the failed analyte/s, either another PT study or a fast turnaround study, and write a corrective action response for the permittee. The permittee is required to submit a completed and signed corrective action report to the state DMR-QA coordinator.
A list of accredited providers can be obtained from the U.S. EPA DMR-QA web site link above. The comprehensive and accurate completion of paperwork submitted helps us to compile and evaluate these studies. Your cooperation and efforts in this matter are appreciated.
