Here’s an in-depth report from Emily Holden, Caty Enders, Niko Kommenda, and Vivian Ho that’s running in The Guardian. Click through and read the whole article and to check out the story map detailing the problem. Here’s an excerpt:
Millions of people in the US are drinking water that fails to meet federal health standards, including by violating limits for dangerous contaminants.
Latinos are disproportionately exposed, according to the Guardian’s review of more than 140,000 public water systems across the US and county-level demographic data.
Water systems in counties that are 25% or more Latino are violating drinking water contamination rules at twice the rate of those in the rest of the country.
America’s worst public water systems – those that have accrued more than 15 “violation points” for breaking standards over five years – serve more than 25m Americans, the research shows. An estimated 5.8m of these are Latino.
Texas, where millions of residents lost access to water and power during the recent storm, has the most high-violation systems, followed by California and Oklahoma. The average number of violations is highest in Oklahoma, West Virginia and New Mexico.
The six-month investigation of five years of Environmental Protection Agency (EPA) and other data also shows how:
Access to clean drinking water is highly unequal in the US, based on race, income and geography Poorer counties have more than twice as many violation points as wealthy ones Some water systems report hundreds of violation points year after year without any action from the government and without being required to notify customers Rural counties have 28% more violation points than metropolitan ones
Scientists and former government officials describe a water regulation system that is broken. “Most policymakers believe compliance with environmental rules is high,” said Cynthia Giles, the former head of enforcement at the EPA under Barack Obama, but that belief was “wrong”.
Experts are most concerned about systems serving smaller communities. They say Latinos are particularly at risk because they often live near industrial farms in California and the west that have polluted local water with nitrates in runoff from fertilizers and manure. They are also more likely to live in the south-west, where arsenic violations are common.
