groundwater

When you think about water pollution, you might think about massive sewer overflows, factory pollution or agricultural runoff. But there’s another source of water pollution that might be in your backyard: septic systems that have failed.

They pollute lakes and streams around the state – and in fact, around the country.

Sean Hammond, deputy policy director for the Michigan Environmental Council, is calling for better rules for septic systems and inspections.

“We are the only state in the country to not have a statewide septic code,” Hammond said.

Dioxane concerns prompt collection of groundwater samples

State officials want to collect water samples in the West Park area of Ann Arbor due to concerns that groundwater contaminated by a toxic chemical may be seeping to the surface.

The Ann Arbor News reports that the Michigan Department of Environmental Quality plans to start the groundwater collection next week.

The chemical is dioxane, an industrial solvent. Federal agencies say long-term exposure could cause health problems, including cancer.

Only 17 miles from Lake Michigan's shore, Waukesha, Wis. wants to replace its contaminated drinking water with water from the lake.

More than 40 conservation groups across the Great Lakes are urging the region's eight governors to veto a proposal to divert water from Lake Michigan.

Waukesha, Wisconsin wants to build a pipeline to the Great Lakes, because its groundwater supply is contaminated with radium.

The federal government has ordered the city to find a new source of drinking water by 2018.

The Michigan Department of Environmental Quality is holding public meetings on Tuesday about a proposal to divert water from Lake Michigan.

Waukesha, Wisconsin wants to build a pipeline to the Great Lakes.

It has a radium problem in its groundwater supply. Radium occurs naturally, but it’s a carcinogen.

The city wants to divert 10.1 million gallons a day from Lake Michigan in the beginning, and up to 16.7 million gallons a day by 2050.

Pollution from the former site of Mount Clemens Metal Products has been spreading across Antrim County for decades, contaminating trillions of gallons of groundwater with trichloroethylene, a cancer-causing chemical.

Michigan has more than 280 contaminated sites that are “orphans.” That means the company that made the mess no longer exists and the state has to deal with it.

But Michigan is running out of money to tackle these environmental problems. That was not good news for Antrim County, home to one of the largest contaminated sites in the country. State management of an underground plume of trichlorethylene (TCE) has been crucial here for years and will be needed in the future.

Waukesha wants to build a pipeline to the Great Lakes.

The city is in southeast Wisconsin, 17 miles from Lake Michigan. It has a radium problem in its groundwater supply.

Radium occurs naturally, but it’s a carcinogen.

Dan Duchniak, general manager of the Waukesha Water Utility, says as the city’s groundwater supply has been drawn down, it’s made the high radium concentration worse.

“And ultimately the radium exceeded the federal drinking water standard and we are now under a court order to come into compliance with that, and the means by which we are going to do that is to develop a new water supply,” he says.

The city has to come up with a permanent solution for its radium problem by 2018.

An environmental group is calling on Michigan lawmakers and President Obama to ban the natural gas extraction process known as “fracking.”

Fracking, or hydraulic fracturing, involves injecting a high-pressure mix of water, sand and chemicals into underground rock formations to release natural gas.

Food and Water Watch says fracking poses an “unacceptable risk” to water supplies and human health. Several recent investigations have shown that fracking contaminated groundwater in several states.

Lynna Kaucheck is with Food and Water Watch in Detroit. She says northern Michigan is a current hotspot for fracking exploration.

“The northern part of the lower Peninsula sits on the Collingwood-Utica shale which is very deep deposits of shale gas. And so right now a lot of out of-state-companies are purchasing mineral rights so they can begin horizontal fracking for natural gas.”

Kauchek says that could to lead to chemically-contaminated groundwater, and pose a risk to the state’s agricultural and tourism industries.

“We don’t believe that fracking can be done safely. Especially not the way that they’re doing it right now.”

State environmental regulators say the gas is so deep in the ground that fracking shouldn’t affect water supplies. They acknowledge some concerns, but say the practice is generally safe.
