Cedar River Water & Sewer District (CRWSD) is required by Federal regulation to participate in lead and copper monitoring every three years. CRWSD water does not contain lead, and lead piping or fittings do not exist within District-owned service lines or distribution system. Any possible lead contamination would come from within the private plumbing system, therefore; lead testing water samples must be collected from within the customer’s home after making contact with private plumbing.
