Children in New Jersey face real dangers from water pollution, both from what they drink and what they play in. Lead, nitrates, and nasty microbes are the biggest problems. This look at the issue pinpoints where the risks come from, who’s most vulnerable, and what we still need to learn to keep kids safe.

New Jersey Kids and Water Contaminants: Why They’re More Vulnerable

Kids aren’t just small adults when it comes to water risks. They drink two to three times more water for their size than grown-ups do. Their bodies aren’t as good at getting rid of toxins, and they absorb more bad stuff like lead and arsenic through their gut. These differences mean kids get a higher dose from the same water. What’s considered safe for adults might not protect a child.

Drinking water dangers in New Jersey: Our state’s water pipes hide some well-known risks for kids. Lead service lines, which connect city mains to homes, were common before 1986. Many are still there in older cities like Newark, Trenton, and Camden. Lead can get into the water from these pipes, especially when water chemistry or pressure changes. Young children absorb up to 50% of ingested lead, compared to about 10% for adults. There’s no safe blood lead level for kids, and even low levels can affect their brains.

Nitrates from farms and septic systems pollute shallow wells in our agricultural areas. Babies under six months are especially at risk for “blue baby syndrome” if nitrate levels go above 10 mg/L as N. If you have a private well, you’re on your own for testing and treating your water. That means some families get less protection than those on regulated city water.

Playing in water can be risky too: Kids swim more often and for longer than adults, and they’re more likely to swallow water. New Jersey’s beaches, lakes, and pools each have their own set of germ and chemical dangers. Harmful algal blooms (HABs) from cyanobacteria can make toxins that are acutely dangerous. Because kids are smaller, these toxins hit them harder. After storms, beaches often close because of high levels of pathogens from combined sewer overflows. This problem often affects kids in lower-income urban coastal areas more.

To really protect New Jersey’s kids from water related health risks, we need a multi-pronged approach. That means protecting water sources, treating water at the tap (especially for well users with reverse osmosis systems), and giving clear guidance for safe recreation.
