A microbiological examination of drinking water generally focuses on Total Coliforms, E.coli and Heterotrophs. Coliform Bacteria are a class of rod-shaped bacteria that can utilize lactose (milk, sugar) as a sole source of food. Coliform bacteria are found essentially everywhere, in soil, lakes, streams and rivers. Generally, coliform bacteria do not cause disease. The presence of coliform bacteria is used as an indication that other disease causing organisms may be present in drinking water.


Water is capable of dissolving and suspending a variety of materials; so getting pure water is very difficult. Many contaminants can dissolve in water from natural sources or as the result of human activity. Chemistry analyses range from dissolved gases: oxygen, carbon dioxide, nitrogen etc... to Metals and Positive ions: arsenic, lead, iron,manganese copper etc...to Negative ions: fluoride, chloride, nitrate, nitrite, etc... We offer many tests to identify and quantify these contaminants in your water.


Radon is a colorless, odorless, tasteless, naturally occurring radioactive gas produced from the decay of uranium-238, which occurs naturally in rocks and soil. Maine and New Hampshire is part of a geological region that is relatively high in natural uranium-238, therefore, radon in water and air is very common in this area. When radon accumulates in indoor air it can pose an increased health risk,primarily lung cancer. Radon gas can also dissolve into well water, which is then released into the air when you use the water.
