New Report Finds 'Erin Brockovich' Carcinogen in Water Supply for 250 Million Americans
By Robert Coleman
In 2016, an EWG report found that chromium-6—a cancer-causing compound made notorious by the film "Erin Brockovich"—contaminated the tap water supplies of 218 million Americans in all 50 states. But our just-released Tap Water Database shows the problem is even worse than that.
Based on test results obtained directly from almost 50,000 local water utilities, drinking water supplies for about 250 million Americans are contaminated with chromium-6. For about 231 million people, drinking water supplies have average levels of chromium-6 exceeding the one-in-a-million cancer risk level determined by California state scientists.
That may still underestimate the number of people exposed because water from most smaller utilities and private wells usually is not tested for chromium-6. Although it's been almost a decade since the National Toxicology Program found the compound caused cancer in rodents when ingested, there are no federal regulations on chromium-6 in drinking water and no federal requirements for regular monitoring of chromium-6 in tap water.
There are a couple of possible reasons for the new, higher numbers in the Tap Water Database.
- The U.S. Environmental Protection Agency (EPA) classifies utilities that purchase finished water from other public utilities as consecutive systems, which are only required to test for disinfectant byproducts, lead and copper. The database suggests that many consecutive systems are buying finished water tainted with chromium-6 from other utilities. To see if your water supplier is a consecutive system and may be purchasing contaminated finished water, look up your supplier in the Tap Water Database.
- California is the only state that set a public health goal and legal limit for chromium-6, and requires water utilities to test for the chemical. EWG's 2016 report was based on data from the EPA's Unregulated Contaminant Monitoring program. The EPA-mandated testing involves only a small number of water utilities that serve fewer than 10,000 people.
We urge the federal government to follow California's lead and set a nationwide legal limit on chromium-6 in drinking water, and require both large and small utilities to test for it. While the legal limit set by California in 2014 was too high to fully protect human health, it represented a step in the right direction. And until regular nationwide testing is required, we can't know the true extent of contamination in public water utilities.

Shower shoes? Check. Extra-long sheets? Yep. Energy efficiency checklist? No worries — we've got you covered there. If you're one of the nation's 12.1 million full-time undergraduate college students, you no doubt have a lot to keep in mind as you head off to school. If you're reading this, climate change is probably one of them, and with one-third of students choosing to live on campus, dorm life can have a big impact on the health of our planet. In fact, the annual energy use of one typical dormitory room can generate as much greenhouse gas pollution as the tailpipe emissions of a car driven more than 156,000 miles.

Kokia drynarioides is a small but significant flowering tree endemic to Hawaii's dry forests. Native Hawaiians used its large, scarlet flowers to make lei. Its sap was used as dye for ropes and nets. Its bark was used medicinally to treat thrush.
States that invest heavily in renewable energy will generate billions of dollars in health benefits in the next decade instead of spending billions to take care of people getting sick from air pollution caused by burning fossil fuels, according to a new study from MIT and reported on by The Verge.
Hawaii's Kilauea volcano could be gearing up for an eruption after a pond of water was discovered inside its summit crater for the first time in recorded history, according to the AP.

From where I stand inside the South Dakota cornfield I was visiting with entomologist and former USDA scientist Jonathan Lundgren, all the human-inflicted traumas to Earth seem far away. It isn't just that the corn is as high as an elephant's eye — are people singing that song again? — but that the field burgeons and buzzes and chirps with all sorts of other life, too.
Humanity faced its hottest month in at least 140 years in July, the US National Oceanic and Atmospheric Administration (NOAA) said on Thursday. The finding confirms similar analysis provided by its EU counterparts.

Indonesia's president has made permanent a temporary moratorium on forest-clearing permits for plantations and logging.
It's a policy the government says has proven effective in curtailing deforestation, but whose apparent gains have been criticized by environmental activists as mere "propaganda."
