The majority of drinking water violations since 2004 have occurred at water systems serving fewer than 20,000 residents, where resources and managerial expertise are often in short supply. It is unclear precisely how many American illnesses are linked to contaminated drinking water. Many of the most dangerous contaminants regulated by the Safe Drinking Water Act have been tied to diseases like cancer that can take years to develop. But scientific research indicates that as many as 19 million Americans may become ill each year due to just the parasites, viruses and bacteria in drinking water. Certain types of cancer â such as breast and prostate cancer â have risen over the past 30 years, and research indicates they are likely tied to pollutants like those found in drinking water.
