What Does “Trace Contaminant” Actually Mean in Drinking Water?

Modern laboratories can detect chemicals at microgram and nanogram levels. Learn how to read these tiny concentrations, what detection limits mean and why presence alone does not determine health relevance.
TFA in Drinking Water: Why the Smallest PFAS Is So Difficult to Remove

When PFAS are discussed, well-known compounds such as PFOS and PFOA usually receive the most attention. Trifluoroacetic acid, or TFA, differs significantly from these substances: it is extremely small, highly soluble in water and moves almost unhindered through soils, water bodies and many treatment processes. In water, it is predominantly present as the negatively charged […]
