PWSA¡¯s Lead Levels Continue to Trend Low

Optimized water treatment keeps lead levels low, building customer confidence in our commitment to protect public health


 

The most recent round of testing completed by the Pittsburgh Water and Sewer Authority (PWSA) reflects lead levels well below the state and federal action level of 15 parts per billion (ppb). This is PWSA¡¯s seventh consecutive round of testing. One hundred ten water samples were taken at high-risk homes with a known lead service line. The results announced today indicate the continued effectiveness of adding orthophosphate to PWSA¡¯s water treatment process. 


With results of 3.58 ppb — remaining historically low for Pittsburgh — customers can have confidence in the effectiveness of our treatment process and trust in our commitment to protecting public health. 


¡°We¡¯re proud that we¡¯ve maintained low lead levels at worst case scenario homes,¡± said PWSA CEO Will Pickering. ¡°These results continue to demonstrate that we¡¯re protecting all of our customers from the risk of lead in drinking water.¡±


Even with low lead levels and a highly effective method of corrosion control, PWSA remains committed to removing all lead service lines from our drinking water system. Since 2016, we have replaced over 10,778 public lead service lines and over 7,578 private ones at no direct cost to customers. We are now more than halfway towards our goal of replacing all public lead lines in our service area. Low-interest loans and grants that do not have to be repaid make it possible to expedite this important work and we remain focused on our goal to replace all lead pipes by 2026.


Orthophosphate as Corrosion Control


 In April 2019, we began adding orthophosphate to reduce lead levels in drinking water while continuing to replace thousands of lead service lines. Orthophosphate is a food-grade additive that forms a protective layer inside of lead service lines, creating an anti-corrosive barrier between the lead pipes and the water flowing through them. This treatment method protects our community from risks of lead while we continue to invest millions per year in replacement efforts.


Adding orthophosphate to the treatment process requires constant monitoring and testing to ensure it is working effectively to protect against lead. Samples are taken from around the system every week, including lead monitoring stations, hydrants, and controlled testing points. Analysts look at lead levels, as well as orthophosphate and pH levels and other markers that influence overall water quality. PWSA plant and field operators, water quality experts, engineers, and data managers constantly review information collected in the field to ensure that PWSA¡¯s drinking water meets all state and federal regulations, and our customers receive reliable, high-quality water. All these efforts are part of PWSA¡¯s commitment to maintain safe, high-quality drinking water.
