Two years after the authority was cited for high levels of a potentially hazardous chemical in its system, the Beaver Falls system, which serves about 17,000 people in 23 communities, is in total compliance with federal regulations, authority general manager Jim Riggio said this week.
The two violations in the authority's annual water quality report for 2011 were not turning monitoring reports in to the state on certain chemicals in time in the first and third quarters of the year.
said the lab where the authority took its water for review missed some chemicals it was supposed to test for.
said, workers resampled the water and had them properly tested.
The revised samples were turned in late, but no elevated levels of chemicals were found, Riggio
said the authority hasn't had problems in the last 18 months with maximum allowable levels of a contaminant called total trihalomethanes or TTHMs.
TTHMs are formed when raw water reacts with disinfectants used in the water system to make it safe for public consumption.
Officials say there is no immediate risk from the contaminant, but studies have shown there could be health risks for those who drink high concentrations of TTHMs over many years.
said the authority solved the problem by switching from chlorine to chloramine to disinfect its water.
Chloramine is formed by adding ammonia to chlorine.
