How did water quality in Montclair, Glen Ridge fare last year?.
The latest Water Quality Report has been issued for Montclair and Glen Ridge, and the results appear to give the drinking water a good-to-swallow grade.
Glen Ridge receives water through its three interconnections with Montclair, according to the report.
The report notes that the state does not require monitoring of certain substances every year, as concentrations of those substances do not change frequently.
The tests also detect levels of contaminants such as lead and copper, along with a batch of substances known as "unregulated" contaminants like dioxane and chromium, where there are no health standards, such as maximum levels established for them.
The last samples were taken in 2015, according to Montclair’s 2016 report; they were included so the township could be transparent in its reporting, said Obszarny.
The readings were conducted as part of the township’s annual drinking water quality testing.
The Water Bureau sent for sampling materials to do additional testing of its wells in compliance with DEP recommendations.
The 2016 Water Quality Report lists PFOA among the unregulated contaminants, with an average of .017 parts per billion found in the 2015 sampling.
According to the DEP’s Division of Water Supply and Geoscience website, the DEP has identified a guidance level of .04 parts per billion for PFOA.
