Diamond, IL 2015 Consumer Confidence Report

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

The Diamond, IL figures for 2015 come from EPA's national Safe Drinking Water database (SDWIS / ECHO) — not a single utility-published PDF. Every value on the Diamond, IL water quality page is transcribed from that public dataset, and you can verify it against the same source below.
