CINNAMINSON, NJ — Most Americans don’t think twice about drinking a glass of water. A report released Wednesday, though, found more than 270 harmful contaminants in local drinking water across the nation, including in the water system used by Cinnaminson. The substances are linked to cancer, damage to the brain and nervous system, hormonal disruption, problems in pregnancy and other serious health conditions.

The nonprofit Environmental Working Group, collaborating with outside scientists, aggregated and analyzed data from almost 50,000 local water utilities in all 50 states. Read more on the Environmental Working Group’s data sources and methodology.

The organization found a troubling discrepancy between the current legal limits for contaminants and the most recent authoritative studies of what is safe to consume.

“Legal does not necessarily equal safe,” Sydney Evans, a science analyst at the environmental group, told Patch.

“A lot of these legal limits are outdated and not necessarily the safe level, and the EWG really wants to fill that gap,” Evans said. “The federal government has not been able to, or is not willing to, set those new regulations to protect public health. We’re trying to fill the gap to let people know, based on the latest science, what the safe levels of contaminants in water are.”

The water that originates from New Jersey American Water’s Mount Holly branch that is used by Cinnaminson was found to have 21 total contaminants between 2012 and 2017. The system serves 47,427 people in the region, according to the environmental group.

Of those contaminants, the following contaminants were detected above the environmental group’s own recommended health guidelines:

• EWG Health Guideline #: 0.7 ppb
• No legal limit

Radium, combined (-226 and -228)

• Potential Effect: Cancer
• 18 times the rate of suggested EWG guideline
• 0.90 pCi/L (Rate this contaminant appears in this utility)
• EWG Health Guideline #: 0.05 pCi/L
• Legal limit: 5 pCi/L

Total Trihalomethanes

• Potential Effect: Cancer
• 48 times the rate of suggested EWG guideline
• 7.17 ppb (Rate this contaminant appears in this utility)
• EWG Health Guideline #: 0.15 ppb
• Legal limit: 80 ppb

In the case of polyfluorinated substances, or PFAs, the environmental group estimated up to 110 million Americans could have the potentially cancer-causing, immune-system damaging contaminant in their drinking water. Yet the EPA requires drinking water utilities across the country to test for only six of 14 known substances in the category.

A variety of other contaminants often found in the water of millions of Americans can profoundly impact health. They include lead, which has been linked to brain damage in small children; arsenic, which can cause cancer; and copper, which can be harmful to infants.

The EPA did not respond to numerous requests by Patch seeking comment on the findings of the study.

According to the environmental group, many of the 270-plus contaminants detected through water sampling are at levels deemed legal under the federal Safe Drinking Water Act, yet are above levels that recent studies have found to pose possible health risks.

“The compounds listed in the EWG report were reported by New Jersey American Water previously to NJ DEP. Most are disinfectant by products, which result from the disinfection process, and we meet all regulatory standards for these,” New Jersey American Water Spokeswoman Denise Venuti Free said. “The remaining compounds are in the source water at levels far below recognized drinking water standards. While we do not specifically treat for these unregulated compounds, their presence is affected by the overall treatment process.

“New Jersey American Water is proud of our water quality record and we work very hard to make sure that our customers have access to their water quality data. Each year, we produce water quality reports for our customers telling them about the quality of their water and make this information available to them on our website. The Environmental Protection Agency (EPA) sets water quality standards intended to protect public health and New Jersey American Water treats and delivers water that meets or surpasses EPA and New Jersey drinking water standards. Further, we participate in community source water protection programs nationwide to help safeguard our water sources. The end result of these efforts is that New Jersey American Water treats and delivers high quality, reliable water.”

The environmental group has a clear opinion on the federal government’s handling of water safety.

“The regulatory system meant to ensure the safety of America’s drinking water is broken. The inexcusable failure of the federal government’s responsibility to protect public health means there are no legal limits for more than 160 unregulated contaminants in U.S. tap water,” Environmental Working Group researchers stated in its “State of American Drinking Water.”

A focal point of the organization’s concern is the Environmental Protection Agency’s refusal to add a single new contaminant to the toxic chemicals list covered by the Safe Drinking Water Act in almost 20 years.

Independent experts agree.

“With the science on what we call ’emerging contaminants’ continuing to grow, it is clear that there are components of our tap water that can be improved,” Kristin Strock, professor of Environmental Science at Dickinson College, told Patch.

Strock, who is not affiliated with the environmental group, also emphasized the challenges in the process of federally regulating harmful contaminants, suggesting the current system is somewhat backward.

“The road to regulating harmful contaminants is difficult, as our current construct for ensuring clean water is based on ‘proving’ that something is harmful before it is regulated as opposed to assuming contaminants could be harmful and ‘proving’ them safe before allowing them to go into industrial production and, as a result, our environment,” she said. “The EPA has been working on identifying safe limits for a number of these emerging contaminants and continues to work on the problem.”

The Environmental Working Group also noted that the every-day person is frustratingly helpless to the chemicals going into their water supply, and the subsequent costs associated with different water filtering techniques.

Olga Naidenko, vice president of science investigation at the group, further explained, “Industries and companies that released PFAS into the environment and drinking water sources — should be responsible to covering such costs, as it is unfair for homeowners to be saddled with costs for pollution they did not create.”

The water group does offer information, though, on filtering technologies that you can use to dramatically reduce water contamination. Filtering technology will help. Carbon filters, for example, will reduce many, but not all, contaminants.

How to Check Contaminants In Your Water:

The environmental group’s public database catalogues contaminants in every water system in the country — the first such database of its kind. First, select the state where you live, and you’ll see state-level data. For more local information, enter your ZIP code.

After you enter your ZIP code, you’ll be directed to a page showing the name of your water utility system. Select “View Utility” to see which contaminants were identified in your area.

What You Can Do

For those with concerns, the environmental group provides a guide to buying water filters. If you find your local water supply has a particularly high level of a dangerous chemical, you can search for a filter that best blocks the specific substance.

While water filters are important, the group also acknowledges they are more of a Band-Aid solution than an actual fix.

“We really want to iterate that’s a first-line, temporary measure,” Evans told Patch. “It’s what you can do today to protect yourself, but really we want long-term permanent change, and that’s going to happen at the community level.”

Subsequently, the environmental group has created a set of seven questions to ask your elected officials about tap water.

The organization strongly believes that everyone can help in the battle to improve tap water safety.

“We absolutely believe in the power of personal advocacy — for individuals to reach out to their local elected officials of all levels. The power of people can come into play,” Naidenko said.
