More Blades-area private wells under investigation for contamination
State environmental and health officials told Blades-area residents Thursday night they’ve shifted their focus to testing private wells after the town's new filtration system significantly lowered contaminants in municipal wells.
Of the 44 private wells tested and the 24 samples returned so far, four homes have been given carbon filtration systems to clear up contaminants.
Three of them had levels of perflorinated compounds above the Environmental Protection Agency's human health advisory of 70 parts per trillion. A fourth well was close enough to 70 ppt that the homeowner was also given a filtration system.
Questions remain, including how one well can be affected while adjacent ones aren’t, and if contaminants can migrate from one well to another.
