Groundwater Monitoring at a Closed Municipal Waste Landfill

Cox-Colvin implements the groundwater monitoring program at this closed municipal waste landfill located in southwestern Ohio in an efficient and cost-effective manner. The landfill is located in the floodplain of the Great Miami River and lies above the Great Miami River Buried Valley Aquifer, a sole-source aquifer in the region. The landfill lies adjacent to a portion of the Miami and Erie Canal.

Landfill operations began in 1972 with the acceptance of domestic, commercial and some non-hazardous industrial wastes. Final closure of the sanitary landfill was completed by April 1990. Certification of landfill closure (sanitary landfill) was submitted to the Ohio EPA and county department of health in early 1990. Post-Closure Care is being conducted in accordance with OAC Rule 3745-27-11. Because of confirmed volatile organic compound (VOC) detections in some of the groundwater monitoring wells, the landfill is being monitored under both the detection monitoring program and the corrective measures monitoring program.

Cox-Colvin personnel provide all necessary professional services for the landfill to stay in compliance with the groundwater monitoring requirements. We perform the semiannual groundwater monitoring, inspect the wells and document any maintenance issues, measure depths to water, validate the laboratory data, conduct statistical analysis, and prepare the semiannual monitoring reports.
