Water reports · SD

Water reports by ZIP code in SD

349 ZIP codes in SD have federal drinking water monitoring records. Each links to what those records show, and to what they do not cover.

SD is the primacy agency code, which is how EPA files a water system rather than where a postcode sits. For most systems it is the state; for systems on tribal land or under direct federal oversight it is a tribe or an EPA region.

A ZIP missing from this list reaches no water system in the federal records we hold. That is not a finding about its water. It is most often a ZIP served by a system too small to have been sampled, or one that is only PO boxes.
