Flint residents knew there was a serious problem with their water when it came out of the tap brown and foul-smelling after the city of Flint changed its source from Lake Huron to the Flint River two years ago. They didn’t know, however, that lead levels were so high that the Environmental Protection Agency could classify it as hazardous waste. It took Michigan Republican Gov. Rick Snyder and the Michigan Department of Environmental Quality more than 17 months to acknowledge the problem. As a result, tens of thousands of Flint residents have been—and continue to be—poisoned.
Sometimes utilities, especially those with publicly elected boards, defer the maintenance of their equipment because raising taxes or rates is unpopular with voters. But updating outmoded infrastructure and securing access to new water sources amid scarcity and drought are expensive tasks. These efforts are pushing rates upward.
It’s unclear whether the billions of dollars that U.S. EPA has required cities to invest in sewer upgrades are yielding water quality improvements, the agency’s inspector general concludes in a new report. The agency has been working since 1998 to curb so-called combined sewer overflows by forcing cities to bring their sewer systems into compliance.
A dime-sized hole in a slender copper pipe could be the culprit in a 1.4 million-gallon loss of drinking water every month in the Green Lake Sanitary Sewer and Water District system.
North Bay politicians unanimously agreed Monday to begin using the additive – ENV CORTROL MAX – on a trial basis. The additive is aimed at reducing corrosion and cutting back on waste. Council heard from staff previously that the additive, which contains small amounts of zinc and phosphate, is fully approved and safe for drinking water.
The majority of which deliver drinking water to the tap — lists aging infrastructure, extreme weather conditions and changing consumption habits as top concerns.
Though it is commonly assumed pressure forces water outthrough leaks, thus preventing water from getting in, a new research study finds evidence confirming the opposite. Contaminants can enter pipes through leaks and travel throughout a water network.
“One small leak from a nail-hole in the pipeline and one crack in the aqueduct is enough to contaminate our water and our entire water supply,” Dennis LeNeveu said. “A big spill is an infrequent event but small spills happen all the time, so this is almost a certainty … It’s almost impossible to stop.”
A national policy to address the problem of lead contamination of drinking water will be published in the coming months, Irish Water has said.
A new report on water supplies in Tasmania’s north-east suggests ageing pipes could be the major source of lead contamination.
An investigative report was released into possible lead-tainted drinking water at schools in the Los Angeles area. The program was a follow-up to a report done by the same station seven years previously that had found old pipes and drinking fountains that could be exposing children and faculty to possible lead poisoning risks.
