Pennsylvania American Water Completes $3.4 Million Lead and Copper Upg...

SINKING SPRING, Pa. (Oct. 9, 2025) - Pennsylvania American Water announced today the completion of a $3.4 million upgrade in its Penn and Glen Alsace Water Districts in Berks County, furthering compliance with updated lead and copper regulations promulgated by the United States Environmental Protection Agency . Work began in fall 2024 and was completed in June 2025. The Lead and Copper Rule Improvements (LCRI) go into effect in 2027 and aim to protect communities from lead and copper in drinking water, requiring rigorous testing and lowering the threshold for the lead action level in water.

Pennsylvania American Water's system upgrades, designed to improve corrosion control and prevent lead and copper from leaching into drinking water, include:

• New chemical storage rooms, pumps and tubing
• Updated process equipment
• The integration of the new feed system into existing production piping

"These investments represent our commitment to proactively protecting public health and staying ahead of regulatory requirements," said Gerald De Balko, manager of engineering for Pennsylvania American Water. "By upgrading treatment processes, we're continuing to provide our customers with the high quality, safe and reliable service they deserve."

Pennsylvania American Water is now performing compliance tests for lead and copper in its Penn Water and Glen Alsace districts through December, with results expected in 2026. These results will be included in the company's annual Water Quality Reports, available online at pennsylvaniaamwater.com/WQReports.

Pennsylvania American Water will also take measures to minimize the risk of lead leaching from service lines and household plumbing by controlling the pH levels in the water exiting its treatment plants and by adding a corrosion inhibitor where necessary.

Pennsylvania American Water's Penn Water District serves approximately 32,000 residents across Sinking Spring and Wyomissing boroughs and the townships of Cumru, Lower Heidelberg, South Heidelberg and Spring. Its Glen Alsace District serves approximately 22,000 residents in St. Lawrence borough and the townships of Amity and Exeter and portions of Earl and Ruscombmanor townships.
