The Federal EPA has issued an update to the Lead and Copper Rule with a requirement for all public water utilities to submit a Lead Service Line (LSL) Inventory. This requirement brings forth an era of exciting possibilities for communities to safeguard the health and safety of their water supply!
The EPA’s Lead and Copper Rule was introduced in 1991 to address health risks posed by plumbing supplies containing lead and copper. The most recent revision requires public water systems to establish an LSL Inventory, enabling identification of customer service lines and a plan for fixing any issues. The revised LCR also requires tap sampling, better communication with customers and schools, and stricter requirements for replacing lead service lines.
This innovative approach ensures that communities can swiftly address potential hazards, prevent public health concerns, and establish a sustainable and reliable water infrastructure for many years to come.
HOW DO I KNOW IF MY SERVICE LINE IS LEAD?
Lead service lines are generally a dull gray color and are very soft. You can identify them easily by carefully scratching them with a key. If the pipe is made of lead, the area you’ve scratched will turn a bright silver color.
DO NOT use a knife or other sharp instrument and take care not to puncture a hole in the pipe!
Note: Galvanized piping can also be a dull gray color. A strong magnet will typically cling to galvanized pipes but will not cling to lead pipes.
Lead service lines can be connected to the residential plumbing using solder and have a characteristic solder “bulb” at the end, a compression fitting, or another connector made of galvanized iron or brass/bronze.

Lead enters drinking water when plumbing materials that contain lead corrode, especially where the water has high acidity or low mineral content that corrodes pipes and fixtures. The Environmental Protection Agency (EPA) requires all community water systems to prepare and deliver an annual water quality report called a Consumer Confidence Report (CCR) for their customers by July 1 of each year and alert you if there is a problem with your drinking water. If your water comes from a well or private water supply, you can check with your health department or with nearby water utilities that use groundwater for information on contaminants in your area.

STEPS TO REDUCE LEAD IN DRINKING WATER
- Have your water tested. Contact your local health department to find out where you can get your water lead levels tested.
- Run your water. Before drinking, flush your home’s pipes by running cold water through the pipes, taking a shower, doing laundry, or doing dishes. Flushing times vary from community to community.
- Use cold water. Only cold water should be used for drinking, cooking, or making baby formula.
- Clean your faucet screen. Regularly clean your faucet’s screen (also known as an aerator). Sediment and lead particles can collect there and get into your water.
- Use a filter. If you use a filter, make sure you use one that is certified to remove lead. Be sure to follow directions and replace expired cartridges. Never run hot water through the filter.
