Lead and Copper in Water

Wisconsin Rapids ground water supply does not contain significant amounts of naturally occurring lead or copper. The naturally corrosive nature of water can dissolve or corrode lead and copper through contact with water service lines, interior pipes and plumbing fixtures.   However, the water from the Water Works and Lighting Commission is basic not acidic having a PH around 8.5.  This keeps the water from dissolving or corroding the inside of the water mains and service lines.
The Water Works and Lighting Commission is required by the EPA to monitor levels of lead and copper in its distribution system.
Lead in drinking water can cause a variety of adverse health effects:

  • In babies and children, exposure to lead in drinking water above the action level can result in delays in physical and mental development, along with deficits in attention span and learning abilities.
  • In adults, kidney problems or high blood pressure could result if water with high levels of lead is ingested over a long period of time.

If you don’t know whether your tap water contains lead you should have the water tested by a certified lab. Proper sampling is required to obtain a valid result. (Note: A single test for lead level in drinking water may not be representative of the level at all times or of the average level over time.)
You can contact the following certified laboratory to get lead and copper sampling procedure information:
