     "text": "Although the scientific understanding of arsenic, its behavior, and how to detect it has steadily advanced, there has not been much research done on what actions, if any, well users have or are taking to reduce their risk of exposure. Because arsenic in water is tasteless and odorless, it is not possible for consumers to recognize arsenic without testing. According to studies completed in Nova Scotia and Maine, testing for arsenic in private wells is often not done because of a low perceived risk for arsenic exposure, inconvenience, and cost of testing. As part of these studies, scientists concluded that the public perception that arsenic is not a health concern prevents actions that could reduce exposure such as water treatment for arsenic removal or development of alternative water sources for private wells. Scientists at the USGS are hoping to evaluate alternative methods of well construction in shallow aquifers in the northeastern United States that could reduce exposure and the need for arsenic treatment systems."

     "text": "It is estimated that there are over 13 million private wells in the United States, and that about 15 percent of the U.S. population, or over 43 million people, rely on private wells for their drinking water. Arsenic is present in groundwater used for drinking water in several regions of the United States, including the northeastern United States and the adjoining Atlantic Canadian provinces. For example, the USGS National Water-Quality Assessment Program determined that more than 10 percent of wells in crystalline-bedrock aquifers in New England contain concentrations of arsenic greater than 10 micrograms per liter, the maximum contaminant level of the U.S. Environmental Protection Agency. According to a National Research Council report on assessments of inorganic arsenic toxicity, even low to moderate (10 to 100 micrograms per liter) levels of arsenic, commonly detected in many private wells, is a public health concern."
