Lead in Drinking Water

Where does lead in drinking water come from? 

Learn about lead in drinking water and how it gets there by checking out this infographic from the U.S. Environmental Protection Agency.

The drinking water from LCA’s water sources (creeks, springs, and wells) is lead-free! However, if buildings have water pipes made of lead or plumbing containing lead, there is a risk for having lead get into the water. This is important for customers to understand because customers must be engaged in solutions to reduce the risk of lead exposure!

IMPORTANT NOTE: The risk of lead exposure will vary from home to home. In some homes, the risk may be from lead-based paint. This continues to be the primary area of concern by public health agencies and the Centers for Disease Control.  Download LCA Fact Sheet # 1: About Lead in Drinking Water

Exposure to lead through water is controlled by LCA’s efforts to ensure our water does not contain corrosive properties that will contribute to lead leaching from the pipes it travels through to get to your tap. Download LCA Fact Sheet # 2: How to Check Your Home for Lead Pipes

If you have a lead service line, lead plumbing, brass fixtures, copper plumbing with lead solder, a water softener, or other treatments system, these are all potential sources of lead exposure to your tap water. Download LCA Fact Sheet # 3: Easy Ways to Reduce Lead Exposure: Rinse Your Pipes & Clean Your Aerators!

LCA Water Testing

Currently, LCA tests for lead in tap water every three years at 50 representative taps of vulnerable homes in the City of Allentown, and at more than 150 homes across all of our service areas in Lehigh and Northampton counties. We do this according to the requirement of the Environmental Protection Agency’s Lead and Copper Rule. The testing results are used to determine if our water continues to be non-corrosive, so that water has minimum potential for lead to leach from plumbing materials. So far, our test results show that the non-corrosive properties of LCA’s water is working to keep lead levels to a minimum.
