Results of the city’s latest water quality testing reaffirm that St. Pete’s water is safe, and lead levels are well within federal regulatory requirements.
In accordance with Environmental Protection Agency requirements, the city’s Water Resources department conducts water quality testing every three years. Five or more samples of the 50 samples tested (90th percentile) cannot exceed the action level of 15 parts per billion (ppb).
The last tests, done in 2014, showed only one sample exceeded the action level.
Water Resources performed additional water quality assurance testing in early 2016, which included additional homes built from pre-1950s to the 1980s. The department sent out more than 850 requests for participation in the testing, though only 86 accepted the request. Of the 86 participants, one home (at 18 parts per billion) was over the action level of 15 parts per billion (ppb). Retesting the home at a later date showed the level was reduced to 5.0 ppb. Two other homes (one at 1.6 ppb and 1.7 ppb) were just above the detection limit of 1.5 ppb.
In addition to the early 2016 tests, Water Resources has added lead analysis to their monthly water quality monitoring at 20 sites around St. Petersburg.
