Caroline Taylor worked for years leading the environmental group Montgomery Countryside Alliance to keep drinking water safe. She was one of around 6,000 Poolesville residents who got a warning earlier in December from town management that drinking water was contaminated (làm nhiễm, ô uế) with two toxins (độc tố). "Many of us worked so hard in the 1990s to get protected by the federal government (chính quyền liên bang) as a sole source aquifer (lớp ngậm nước)," said Taylor. And at the time, the water was tested to be high quality. So we were so proud of this. And so protective of it and to find "forever chemicals,' perhaps tainting it and making it dangerous. It's tough."
