Water Testing Results

On July 12, the Pittsburgh Water and Sewer Authority (PWSA) released results from the first of two compliance tests for lead and copper to be conducted in 2016.

As you may have heard via the media, 55 of the 100 homes tested had detectable levels of lead, ranging from 2.1 to 75 parts per billion (ppb). Levels that exceed 15 ppb may require additional action on the part of the authority, such as additional water quality monitoring, more effective corrosion control treatment, source water monitoring/treatment, public education, and lead service line replacement.

Blawnox Borough purchases its water from the Fox Chapel Water Authority, who obtains their water from PWSA. While Blawnox recently tested the water supplies in 20 Borough homes for lead and copper, none of these sites were included in the data released by the PWSA. The 100 homes tested by the PWSA were all within City of Pittsburgh limits.

The Borough has just gained access to results from the testing that was done in June, and the values are under the actionable levels of 15 ppb for lead, ranging from 0.00 to 12.0 ppb. Note that 15 of the 20 tested homes had no detectable levels of lead, while 1 each had 1.0, 2.0, 3.0, 6.0 and 12.0 ppb.

Blawnox Borough will continue to strive to provide its residents with clean, safe drinking water now and into the future. If you would like to see the Borough's results, go to the Drinking Water Reporting System website — our ID number is 5020004.
