Press Release
PWSA Water Quality Statement Order From the DEP

Delivering quality water to all of our customers has been the #1 priority for The Pittsburgh Water and Sewer Authority (PWSA) since founded over 30 years ago.

PWSA strives to meet all of the treatment, testing, and reporting requirements set by Allegheny County, Pennsylvania, and federal agencies. PWSA regularly monitors water quality and promptly makes any necessary adjustments.

On April 25, 2016, the Pennsylvania Department of Environmental Protection (DEP) issued an Administrative Order to PWSA requiring testing relating to lead and copper and public notice concerning it. The order is an important part of the compliance process and PWSA will continue to cooperate with DEP to resolve the issues covered by it.

The order is based on treatment practices during parts of 2014 and 2015 directed by prior management. They are no longer used by PWSA. During that time PWSA switched corrosion control agents from soda ash to caustic soda, both recognized as effective in corrosion control. PWSA failed to follow the proper DEP notification procedure in implementing this change.

Issuance of this order follows over a month of cooperative discussions between PWSA and DEP. PWSA has already addressed some of DEP’s requirements, while others are in the planning stages.

In addition to these steps, PWSA sponsors free voluntary residential testing program and works to educate the community on water quality. Those who would like more information on water quality and the testing program can visit
