Your pipes tell a different story

The data above shows what leaves the treatment plant—not what comes out of your faucet. Old pipes, lead solder, and building plumbing can add contaminants the city never tests for. Know exactly what's in your Springfield tap water.

About Lead in Drinking Water

What is Lead in Water?

Lead is a toxic metal that can dissolve into drinking water from older pipes, solder, and fixtures. It's invisible, tasteless, and odorless, making testing the only way to detect it. The EPA has set an action level of 15 ppb, though they emphasize there is no safe level of lead exposure.

Potential Health Effects

Children

Developmental delays, learning difficulties, lower IQ, behavioral issues

Adults

High blood pressure, kidney damage, reproductive issues

How to Reduce Exposure

  • •Run water for 30 seconds to 2 minutes before drinking, especially in the morning
  • •Use cold water for cooking and drinking (hot water dissolves more lead)
  • •Install a NSF-certified filter designed to remove lead
  • •Test your water, especially if your home was built before 1986
