New England Water Problems
Many New England towns have fairly similar water quality issues. Some problems arise from natural minerals in the ground, others are man-made. Common are low pH, dissolved and particulate iron, manganese, calcium & magnesium (the hardness minerals), bad odors & tastes. Even the health threats arsenic and radon are not uncommon. More recently a chemical known as PFAS has become a concern in certain areas.
We start by getting a reliable water sample and test, analyzing it and understanding how it can be resolved. Water usage estimates, plumbing considerations and other factors also weigh on a final recommendation. Find and click on your town to learn about getting the optimal solution or give us a call or email us:
