Lead and Copper in Drinking Water

  • Lead and copper are common metals found in the environment. Drinking water is one possible source of exposure to these metals due to their widespread use in distribution system materials.  

    Please visit Michigan.gov/MILeadSafe for information on exposure to lead in drinking water and more.

    The purpose of the Lead and Copper Rule (LCR), is to control lead and copper levels by reducing water corrosivity. All community and nontransient noncommunity water supplies (types of public water supplies) must meet the LCR requirements.
