Laverne, OK 2003 Consumer Confidence Report
The original annual drinking-water report. Every number on the Laverne, OK water quality page is pulled from this document.
The Laverne, OK figures for 2003 come from EPA's national Safe Drinking Water database (SDWIS / ECHO) — not a single utility-published PDF. Every value on the Laverne, OK water quality page is transcribed from that public dataset, and you can verify it against the same source below.
