01 · What we test
Two sub-services.
One environmental lab.
Pick the sub-service that matches your matrix and regulatory bar. Multi-residue pesticide panels for soil and produce, and the drinking-water + food panels FDA and EPA write rules about.
02 · Compliance
EPA, FDA, and the methods regulators cite.
Every environmental COA we sign maps to a published EPA or FDA method, with method-blank QC, surrogate / isotope-dilution recovery, and chain of custody on the report. Built for utilities, NPDES dischargers, Phase II ESA consultants, and food brands shipping into Costco, Whole Foods, and Amazon Brand Registry.
EPA 533 / 537.1 / 1633
PFAS reference methods
EPA 533 (isotope-dilution direct injection) and EPA 537.1 (SPE) for finished drinking water; EPA 1633 (40-analyte) for wastewater, surface water, soil, sediment, biosolids, and tissue. The full PFAS reference-method catalog on one bench.
EPA 200.8 / 6020
Drinking-water & wastewater metals
EPA 200.8 ICP-MS for primary MCL drinking-water metals (Pb, As, Cr, Cd, Hg, Sb, Ni, Se, Tl, Be, Ba, Cu); EPA 6020 for total recoverable metals after acid digestion in wastewater, soil, and biosolids.
FDA Closer to Zero
Heavy metals in baby food & juice
Inorganic As (100 ppb infant rice cereal, 10 ppb juice), Pb (10 ppb juice, 20 ppb root vegetable baby food), Cd, and Hg under the FDA Closer to Zero plan. Reported on every food / beverage COA.
21 CFR 109
Aflatoxin & mycotoxin tolerances
FDA action level 20 ppb total aflatoxins (0.5 ppb M1 in milk), EU action 2 ppb B1. We report both bases on the COA so importer and domestic-buyer specs can both be met.
