Lead Service Line Inventory

Jump to the Survey →

The City of Jefferson is required to conduct Lead and Copper testing at least every three years at various locations throughout our water distribution system. There is no safe level of lead exposure. In drinking water, the primary source of lead is from pipes, which can present a risk to the health of children and adults.

On December 16, 2021, the EPA announced its next steps to strengthen the regulatory framework on lead in drinking water. With their new proposed guidelines, a database of materials used in our water customer’s service lines and plumbing is required. You can visit https://www.epa.gov/ground-water-and-drinking-water/revised-lead-and-copper-rule to learn more about the EPA requirements.

The City of Jefferson is asking for your help to determine the material from which your water service line is made. Please follow these easy steps to report your findings to the City.

If you have questions or concerns, please contact the Jefferson Water Department at 515-386-2611 or jeffwaterplant@hotmail.com

Step 1: Locate the Water Service Line & Test Area

The water service line is typically found in the basement. Identify a test area on the pipe between the point where it comes into the building and the inlet valve. If the pipe is covered or wrapped, expose a small area of metal.

Step 2: Test the Pipe Material

You can find out your type of pipe by doing the scratch, magnet and tapping tests. Take note of the reaction.

Lead: Scraped area is shiny and silver, magnet will not stick, tapping a coin makes a dull noise. Copper: scraped area is copper, magnet will not stick, tapping a coin makes a metallic ringing noise. Galvanized: scraped area remains a dull gray, magnet sticks, tapping a coin makes metallic ringing noise.
