About this file
This file is a Class A Biosolids Data Summary from Chambers Creek Regional Wastewater Treatment Plant for 2024, detailing monthly analytical results for metals content in biosolids managed by Pierce County, Washington. The document presents laboratory analysis data collected from January through October 2024 using EPA SW-846 methods, measuring concentrations of arsenic, boron, cadmium, chromium, copper, cobalt, mercury, potassium, molybdenum, and nickel (with the nickel data appearing incomplete). Each metal is reported with its detection limit, monthly measurements, average and maximum concentrations, and percentage of application limits established for biosolids land application. The data demonstrates that biosolids quality remained relatively consistent throughout the monitored period, with most metals maintained well below regulatory thresholds for Class A equivalent biosolids designation.
The analytical results indicate that Pierce County's biosolids meet stringent quality standards required for beneficial use applications. Key findings show that copper represented the highest percentage of application limit at 20 percent, while nickel and mercury each constituted 10 percent and 17 percent of their respective limits. All other measured metals remained significantly below their application limits, with arsenic at 41 percent, cadmium at 39 percent, and molybdenum at 19 percent of allowable thresholds. These measurements provide documentation supporting the County's biosolids management compliance with federal and state environmental regulations and inform the County's RFP 2026-RFP-189 for biosolids beneficial use services, which seeks a qualified contractor to manage approximately 5,000 wet tons annually of Class B biosolids for processing and disposal.
