Lead is NOT present in Rockford's source water (groundwater), nor is Lead in Rockford's treated drinking water. However, if buildings have water service lines made of Lead, Lead can enter the drinking water through the corrosion of plumbing materials.

Steps to Reduce Exposure to Lead in Drinking Water
Despite our best efforts mentioned earlier to control water corrosivity and remove lead from the water supply, lead can still be present in some homes or buildings. Advice for lead safe water practices include:
- Before using any tap water for drinking or cooking, flush your water systems by running the kitchen tap (or any other tap you take drinking or cooking water from) on COLD for 1-2 minutes.
- Remove and clean faucet aerators regularly to eliminate any debris such as metal particulates.
- Purchase or lease a home water treatment device. Various types of water treatment devices are certified for household use and can remove a broad range of contaminants from water – including lead. Any type of water treatment device that you choose should meet National Sanitation Foundation (NSF) standards.
- Test water in houses with older plumbing. For more information on having your water tested by a certified lab, please call 779-348-7151.

The City of Rockford has source water that is naturally hard (calcium carbonate), and has a neutral pH. The minerals that cause hardness coat the inside of your internal plumbing. This coating prevents lead from dissolving into drinking water. The City also treats the water with a food grade polyphosphate in accordance with the Lead and Copper Rule. This treatment further coats household plumbing and helps reduce the exposure of Lead in drinking water.
The Lead and Copper Rule:
The City of Rockford is in full compliance with the Lead and Copper Rule (LCR). This rule requires that a utility sample water from resident’s kitchen cold water tap that has been in contact with the internal plumbing for 6 hours. Rockford is on a reduced monitoring schedule which takes place every three years as a result of many consecutive years of compliance with this program.
