Watseka, IL 1998 Consumer Confidence Report

The original annual drinking-water report. Every number on the Watseka, IL water quality page is pulled from this document.

The Watseka, IL figures for 1998 come from EPA's national Safe Drinking Water database (SDWIS / ECHO) — not a single utility-published PDF. Every value on the Watseka, IL water quality page is transcribed from that public dataset, and you can verify it against the same source below.
