Whether you have city water or well water, it’s important to treat the water that comes into your home. You drink it, you wash with it, you play in it, and you rely on it.

Well Water

Having your own well for drinking water means that you are solely responsible for the quality and safety of your water. Many wells have issues such as iron (rusty water), hard water (scale), and sulfur (rotten egg odor). These may not necessarily be harmful to your health, but they can sure make a mess! Other issues that commonly arise with private wells can cause serious health concerns, such as nitrates, E. coli, total coliform bacteria, and even arsenic. It is important to get your water tested regularly to ensure your water is safe to consume.

City Water

Most people receive water to their home from a municipal source or Public Water Supply (PWS). The PWS does a good job treating the water before it leaves the plant. However, contaminants or additives can slip through this process, giving water a bad taste or potentially leaving the water harmful. The distribution system can have leaks that can introduce contaminants, often leading to “Boil Water Advisories.” Other issues with municipal water can be high hardness (scale), chlorine (used for disinfection), fluoride (added to water), lead services into homes, and, of more recent concern, pharmaceuticals that get past the municipal treatment system.
