Pacific Watershed Associates has been retained by Humboldt Waste Management Authority (HWMA) since 2005 to provide ongoing water quality monitoring, analysis, reporting, and technical oversight at the Cummings Road landfill under a Clean-up and Abatement Order (CAO) levied by the North Coast Regional Water Quality Control Board. The CAO was issued in response to sediment discharges associated with the failure of the surface drainage infrastructure following heavy rains in the fall of 2005 (see: Cummings Road Landfill Erosion Control). Our technical staff conducts periodic inspections, water quality sampling and water quality analysis in response to heavy rainfall events (> 1" per day), while also providing oversight for landfill staff who conduct most of the water quality monitoring required at drainage outfalls and in-stream monitoring sites. PWA also performs all water quality data analysis and reporting requirements under the CAO for HWMA.
