About this file
This file is a Class A Biosolids Content Summary from Chambers Creek Regional Wastewater Treatment Plant for 2025, documenting monthly metal concentration data and biosolid land application compliance metrics. The spreadsheet presents analytical results for metals including arsenic, boron, cadmium, chromium, copper, and cobalt, measured using EPA Method SW-846 6010D with corresponding detection limits. Monthly data is provided for January through December, with average and maximum values calculated across the year. The data includes land application percentages relative to established limits, with values ranging from 2 percent for cadmium to 41 percent for arsenic. The biosolids are classified as Class A EQ (Exceptional Quality), indicating they meet the most stringent regulatory standards for environmental protection and public health.
The file demonstrates Pierce County's Chambers Creek facility maintains biosolids quality well below regulatory thresholds across all monitored metals. Metal concentrations remain relatively consistent throughout the year, with some months marked as "N/A," likely due to operational or sampling variations. The data supports the County's biosolids beneficial use program under RFP 2026-RFP-189, which seeks qualified contractors to receive and process approximately 5,000 wet tons annually of Class B biosolids at a base contract value of $500,000 over an initial four-year term with optional one-year extensions. This analytical documentation provides the technical foundation for demonstrating regulatory compliance and supporting the beneficial reuse of biosolids as an amendment or soil conditioner in qualified applications.
