Analysis of Wastewater, Sludge/Biosolids, Leachate and Other Complex Environmental Matrices for Metformin and Guanylurea to Environment and Climate Change Canada

Environment and Climate Change Canada is soliciting a supplier to provide high-quality chemical analysis of Metformin and Guanylurea across various environmental matrices, including raw influent, treated effluent, landfill leachate, surface waters, sludge, biosolids, sediment, and soil. This work supports a monitoring program on the occurrence and fate of chemical substances in municipal wastewater. The contract structure consists of one firm period ending March 31, 2027, with four subsequent one-year option periods extending through March 31, 2031. Estimated annual volumes include 90 wastewater, 30 surface water, 30 biosolids, and 15 landfill leachate samples. The selection process is based on a weighted ratio of 70 percent technical merit and 30 percent price. To be compliant, bidders must hold ISO/IEC 17025 accreditation from an ILAC MRA signatory and provide summaries of fully validated analytical methods for aqueous and solid matrices. Technical evaluation focuses on experience in ultra-trace analysis of pharmaceuticals and personal care products per EPA Method 1694 and the ability to meet strict reporting limits, such as 5 ng/L for Metformin and 50 ng/L for Guanylurea in effluent. The successful contractor must use labeled surrogates for isotope dilution and retain all raw laboratory data and chromatograms for at least 36 months.
