the reliance on untreated well water in the rural regions of the marcellus leaves communities at a strong disadvantage if aquifer contamination would occur. it has been found that methane concentrations in well water within one kilometer from an active gas well were 17 times higher than in those outside of active gas production area. produced water includes naturally occurring radioactive materials, as well as high levels of brine, barium, strontium, and radium. at high exposure levels, these contaminants have been shown to cause skin rashes, nausea, abdominal pain, breathing difficulties, headaches, dizziness, eye irritations, throat irritations, and nosebleeds. residents are also exposed to a myriad of air pollutants through mechanisms such as well-venting and flaring. volatile organic compounds, diesel particulate matter, and methane are found in elevated levels around producing wells, often in concentrations that exceed epa guidelines for carcinogenic health risks. unfortunately, there have been no studies to try and quantify the cumulative impacts of multiple low dose exposures.

bullet::::- consumption of untreated water (well water): many studies have linked "blastocystis" infection with contaminated drinking water. a 1993 study of children infected symptomatically with "blastocystis" in pittsburgh indicated that 75% of them had a history of drinking well water or travel in less developed countries. two studies in thailand linked "blastocystis" infection in military personnel and families to drinking of unboiled and untreated water. a book published in 2006 noted that in an oregon community, infections are more common in winter months during heavy rains. a research study published in 1980 reported bacterial contamination of well water in the same community during heavy rainfall. a 2007 study from china specifically linked infection with "blastocystis sp. subtype 3" with drinking untreated water. recreational contact with untreated water, for example though boating, has also been identified as a risk factor. studies have shown that "blastocystis" survives sewage treatment plants in both the united kingdom and malaysia. "blastocystis" cysts have been shown to be resistant to chlorination as a treatment method and are among the most resistant cysts to ozone treatment.
