Has the Water in Flint Become Safe for Bathing?

Municipal water in Flint, Mich., has improved significantly and is safe for bathing and showering, although people should continue filtering the water before drinking it, scientists said Tuesday.

Marc Edwards, a Virginia Tech engineering professor whose testing last summer confirmed lead contamination of the city’s water, said sampling in recent months has found that lead levels are steadily declining. Also trending downward are bacteria that can cause Legionnaires’ disease, while byproducts from disinfectant chemicals are at normal levels.

“We’re seeing some very, very encouraging results,” Edwards said at a news conference in Flint, adding that he was “pretty hopeful” the water would meet federal standards for lead content within the next six months. Results of another round of testing expected in August will make the situation clearer, he said.

The economically struggling city of nearly 100,000 has been dealing with poor water quality since switching from the Detroit system, which draws from Lake Huron, to the Flint River in April 2014 as a short-term measure to save money while another pipeline to the lake was under construction.

Residents quickly complained of bad tastes, odors and colors. E. coli bacteria hit unsafe levels. And last September, state officials acknowledged failure to add chemicals to limit corrosion had enabled the river water to scrape lead from aging pipes, exposing people in some homes and schools to the potent neurotoxin.

The city was under state management at the time, leading to an apology from Gov. Rick Snyder. State officials approved returning Flint to the Detroit system in October 2015.

Edwards, who has strongly criticized state and federal agencies’ handling of the matter, was hired by the city in January to oversee water testing independently, with his work funded through private donations.

He said Tuesday that resumption of phosphate treatments to coat pipes and reduce corrosion was having a positive effect. A program that provides financial assistance for water use has encouraged people to flush more water through the system, washing away lead-tainted rust, he said.

Sampling of water in large and small buildings showed a decline in legionella bacteria readings from October to March, said Amy Pruden, another Virginia Tech professor.

Despite the scientists’ reports of improvements, some Flint activists and outside groups remain skeptical. Water Defense, an organization founded by actor Mark Ruffalo, has raised concerns about the safety of water inside hot-water heaters and the absence of government standards for baths and showers. Of particular concern to Water Defense is the presence of byproducts generated by use of chlorine to disinfect water, which in high concentrations can be unhealthy.

Edwards and two other water specialists — David Reckhow of the University of Massachusetts and Shawn McElmurry of Wayne State University in Detroit — said during the news conference their analyses had shown that levels of disinfectant byproducts in Flint water were typical of those in other cities.

“There’s nothing out of the ordinary from what we see,” Reckhow said.
