I have used Atlas Water Systems for the last 10 years. When I first moved in to my house in Westford, Ma, I realized we needed more water treatment to deal with the iron and sulfur smell. I spoke with Skillings and Sons and they wanted me to make an investment of about $25,000.00. I started to do some research and realized that there were alternatives. Altas worked with my budget and was able to accomplish this task for about 1/3 of the cost. I most important thing about choosing a water treatment company is the serviced. Altas has great service. Ready to service you when ever you have a need, even on the weekends.
