0 mg/l This result is recorded as a detection, and the figure the agency wrote — "0.00" — is zero to the precision it was written to. Read the zero as "smaller than the written figure resolves", not as "none present". SDWIS holds a separate numeric concentration that Drinking Water Watch does not publish, so this endpoint does not carry it either; no more precise magnitude is available here. , sample collected Jun 10, 2010, sampling point MRT000 Total Haloacetic Acids (Haa5) 2456 Jan 1, 2008 – Dec 31, 2010
