After analyzing federal data, the New York Times found that 20 percent of the nation’s water treatment systems have violated key provisions of the Safe Drinking Water Act over the last five years.

That law requires communities to deliver safe tap water to local residents. But since 2004, the water provided to more than 49 million people has contained illegal concentrations of chemicals like arsenic or radioactive substances like uranium, as well as dangerous bacteria often found in sewage.

Regulators were informed of each of those violations as they occurred. But regulatory records show that fewer than 6 percent of the water systems that broke the law were ever fined or punished by state or federal officials, including those at the Environmental Protection Agency, which has ultimate responsibility for enforcing standards.

Studies indicate that drinking water contaminants are linked to millions of instances of illness within the United States each year.

In some instances, drinking water violations were one-time events, and probably posed little risk. But for hundreds of other systems, illegal contamination persisted for years, records show.

The New York Times has compiled and analyzed millions of records from water systems and regulators around the nation, as part of a series of articles about worsening pollution in American waters, and regulators’ response.

An analysis of E.P.A. data shows that Safe Drinking Water Act violations have occurred in parts of every state.

In the prosperous town of Ramsey, N.J., for instance, drinking water tests since 2004 have detected illegal concentrations of arsenic, a carcinogen, and the dry cleaning solvent tetrachloroethylene, which has also been linked to cancer.

In New York state, 205 water systems have broken the law by delivering tap water that contained illegal amounts of bacteria since 2004.

However, almost none of those systems were ever punished. Ramsey was not fined for its water violations, for example, though a Ramsey official said that filtration systems have been installed since then. In New York, only three water systems were penalized for bacteria violations, according to federal data.

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.

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 — such as breast and prostate cancer — have risen over the past 30 years, and research indicates they are likely tied to pollutants like those found in drinking water.

The violations counted by the Times analysis include only situations where residents were exposed to dangerous contaminants, and exclude violations that involved paperwork or other minor problems.

The E.P.A. has reported that more than three million Americans have been exposed since 2005 to drinking water with illegal concentrations of arsenic and radioactive elements, both of which have been linked to cancer at small doses.

In some areas, the amount of radium detected in drinking water was 2,000% higher than the legal limit, according to E.P.A. data.

But federal regulators fined or punished fewer than 8 percent of water systems that violated the arsenic and radioactive standards. The E.P.A., in a statement, said that in a majority of situations, state regulators used informal methods — like providing technical assistance — to help systems that had violated the rules.

Many systems remained out of compliance, even after aid was offered, according to E.P.A. data. And for over a quarter of systems that violated the arsenic or radioactivity standards, there is no record that they were ever contacted by a regulator, even after they sent in paperwork revealing their violations.

Those figures are particularly worrisome, say researchers, because the Safe Drinking Water Act’s limits on arsenic are so weak to begin with.

A system could deliver tap water that puts residents at a 1-in-600 risk of developing bladder cancer from arsenic, and still comply with the law.

We will be sure to follow this story as it continues to develop. There have been 100’s of similar stories over the last decade – a sign that the general public is becoming more concerned about water quality.

Information like this makes a comprehensive water treatment system like the Pureoflow an easy choice when it comes to “piece of mind”. No matter what you start with, the right treatment system can deliver safe, clean drinking water.
