EPA’s Arsenic Rule Results in Fewer Incidents of Cancer A recent New York Times article reports that the EPA’s revised rule on arsenic contamination in public drinking water systems has resulted in fewer lung, bladder and skin cancers. This finding, published last month in Lancet Public Health journal, is the result of a study that compared the urinary arsenic levels of over 14,000 people in 2003, before the new rule went into effect, to those in 2014, well after the rule had been fully implemented. The researchers found a 17 percent reduction in arsenic levels in this time period and they estimate that this reduction has resulted in 200-900 fewer lung and bladder cancers and 50 few skin cancers annually. This finding is reassuring to water systems that have spent time, money and effort on arsenic rule compliance – it is always good to know that regulations are truly making a difference in the lives of community members. It also highlights the importance of water systems, and especially those with groundwater sources, working with their local and state officials to determine the best way to test for arsenic and, if necessary, treat their water supply. And because two water systems with similar levels of arsenic in their source water often need two entirely different types of treatment technology, and because these technologies can be expensive, knowledge about arsenic compliance, treatment and funding sources is essential. Luckily, WaterOperator.org can help point you in the right direction when you choose "arsenic" as the category in our document database. A good first stop is also this EPA webpage which offers lots of resources and tools to operators, such as a rule summary and steps to take towards compliance.

Featured Video: Arsenic Treatment in a Rural Town Over time, low levels of exposure to arsenic can result in cancer. This is a sobering fact for anyone, but it's particularly challenging for small rural towns with arsenic in their drinking water. When neither the utility nor the residents have access to other water options, treatment is of the utmost importance. But because arsenic doesn't cause taste or odor issues, or produce immediate health effects, getting that treatment in place can sometimes be difficult. Learning how other small utilities did it can help. In this week's video, the manager of a small rural utility in Montana introduces his utility and describes how they chose to put arsenic treatment in place for their system. For more on arsenic in drinking water topics, see this USEPA factsheet (PDF), or search our document database using the category Arsenic.
