What are the common contaminant problems here in Massachusetts that might cause a public health problem?
E.coli is a common bacterium found in all animals, including humans. When it is found in water it is usually associated with fecal matter and indicates there could be a public health problem. Giardia is a parasite carried by beavers and other mammals. It is only found in surface water supplies. If there is a possibility that Giardia is present the system must test for this organism. Cryptosporidium is a parasite commonly found in lakes and rivers, especially when the water is contaminated with sewage and animal wastes. It is very resistant to disinfection and even a well-operated water treatment system cannot ensure that drinking water will be completely free of this parasite. Immune-compromised people and people with gastrointestinal diseases who wish to take extra precautions should consult their health care provider about measures to reduce risk of Cryptosporidium, Giardia, and bacterial infections. Boiling water is one way of removing Cryptosporidium and bacteria. Point-of-use trea
