What You Can Do in Northampton

  1. Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
  2. Install a certified water filter. For Total organic carbon, listed in the water-quality records for Northampton: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
  3. Check your home's plumbing. With 69% of homes built before 1986, lead solder is a real possibility.
