The primary cause of a water sample failing to meet the EPA standards for potability (safe to drink) is bacteria in the water. Eliminating the bacteria, which can be both in the well and in the piping in the home, requires disinfecting the system with a chlorine bleach solution. It’s a relatively simple process, and we can send you instructions on how to do it if your sample comes back “positive” for bacteria content.

Other contaminants will require installation of a treatment system. Here’s some of the choices, along with their advantages and limitations.

Another option is a “Complete” water analysis, which includes all the characteristics and contaminants listed below. Both the “FHA” and “Complete” water tests require approximately six calendars days from the date the sample is taken to get results by email.
