10 percent of Michigan's septic fields stink: 130,000 of them failed

Septic systems in Michigan don't adhere to uniform standards
user: Soil Science Flickr

An interview with Jeff Alexander.

You're about to read something you might not want to spend much time thinking about, but that doesn't mean it's not important. 

That subject is septic fields. Of the 1.3 million wastewater treatment systems in Michigan, nearly 10 percent have failed. That's about 130,000 systems. 

With thousands of failing septic systems throughout the state, what's that doing to our water?

Michigan is the only state in the Union that doesn't have uniform standards governing how on-site sewage treatment systems should be designed, built, installed and maintained. 

Jeff Alexander recently examined the state of Michigan's septic fields in an article featured in Bridge Magazine

Michigan Radio's Cynthia Canty spoke with Alexander about what scientists at Michigan State are finding.

US EPA to propose rules on wastewater from power plants

DTE's Monroe Power Plant would have to treat its coal slurry under a proposed EPA rule.
cford3 Wikipedia

Burning coal in a power plant creates byproducts called fly ash and bottom ash.  That ash contains a lot of bad stuff - mercury, lead, arsenic, to name a few.

While some plants ship the dry ash to landfills that accept hazardous materials, others mix the ash with water to make a slurry, which is moved into holding ponds.

Eventually, the water in those ponds is released into the nearest waterway.

Anderson Eye Care Facebook.com

You can listen to today's Environment Report above.

The Grand River hit a record high level in Grand Rapids over the weekend.  Volunteers spent hours filling sandbags to protect homes and city buildings.

City managers are still dealing with the flood waters. But they’re also planning for future storms.

Haris Alibasic directs Grand Rapids’ Office of Energy and Sustainability.

“Given the more intense and more frequent, intense rain events we’re probably going to be experiencing, as climate change is anticipated to really have a serious impact in the Midwest," he says.

Cleaning up a big, underground mess in Michigan (PHOTOS)

In 2007, Logan's Gas and Deli lost 8,000 gallons of gas underground. The owners walked away, and the state is still cleaning up the mess.
Mark Brush Michigan Radio

There are around 4,800 gas stations in Michigan, but at one time, there were a lot more. It seemed like just about every corner had a gas station on it.

Many of those gas stations are closed now, but taxpayers are often on the hook for what’s been left behind.

I visited one of these polluted sites recently with representatives from the Michigan Department of Environmental Quality (MDEQ). The heavy traffic along State Route 89 near Battle Creek makes it a perfect place for a gas station.

And for a long time, things were going well for Logan’s Gas and Deli.

DTE to start pollution cleanup in Ann Arbor this week

Kevin Lund, a senior geologist at the MDEQ's Department of Remediation, kicks over gravel to reveal the pollution along the Huron River in Ann Arbor.
Mark Brush Michigan Radio

Starting today, DTE plans to bring in the heavy equipment needed for the pollution cleanup along the Huron River west of the Broadway Bridge in Ann Arbor.

Black, oily coal tar pollution has been underground for decades.

It was left behind by an old manufactured gas plant owned by the utility company. Two years ago regulators discovered the coal tar was getting into the river. Now, DTE plans to spend between $2-3 million digging it out.

Report: No contamination found in well water in Kalamazoo River oil spill zone

Oil spill clean up work along the Kalamazoo River, near Battle Creek, July, 2010
(Steve Carmody/Michigan Radio)

Tests suggest household wells near the 2010 Kalamazoo River oil spill have not been contaminated.

A pipeline break in July, 2010, resulted in more than 800 thousand gallons of crude oil leaking into the Kalamazoo River.   The cleanup of the river and the surrounding area continues.

Health officials have spent the past few years testing 150 wells in the spill zone.

New phase of Muskegon Lake restoration begins

Muskegon Lake.
Muskegon County

Muskegon Lake is on a list of polluted hot spots around the Great Lakes called Areas of Concern. It made that list because of decades of industrial pollution.

Richard Rediske is a professor of water resources at Grand Valley State University. He says the last phase of cleanup is underway. The next step will be to improve habitat for fish and wildlife.

Rediske is working on projects to restore wetlands and remove debris at an old sawmill site. He says he expects it’ll take another five years to get Muskegon Lake off the Areas of Concern list. It was listed in 1985... so, getting the lake cleaned up and restored will end up taking more than three decades.

“That’s pretty much typical. White Lake to the north of us is actually going to be delisted this year so they’re a little ahead of us. It takes a long time to assess the problems and then fix them.”

Michigan has 14 Areas of Concern.

Michigan turtles still feeling effects of oil spill

A rescued oiled turtle ready for cleaning
Herpetological Resource and Management

According to an article in the Battle Creek Enquirer, turtles are still suffering negative effects from last year's oil spill in west Michigan's Talmadge Creek and Kalamazoo River.

Scientists including Bob Doherty have been working to rehabilitate affected turtles and document the extent of the damage to turtle populations caused by remaining submerged oil.

Doherty is under contract with Enbridge Inc., the company responsible for the spill.

Doherty and his staff will administer care to some 30 rescued turtles in the coming months who are not healthy enough to return to the wild for winter hibernation.

Two Michigan pollution hotspots show signs of improvement

Great Lakes Areas of Concern
EPA website

Two of Michigan's "Areas of Concern," heavily polluted sites around the Great Lakes region, have seen recent progress in terms of cleanup. This according to state environmental regulators.

The Associated Press reports:

The U.S. and Canada designated 43 toxic hot spots in the region in the late 1980s. Among them are Muskegon Lake and the Upper Peninsula's Deer Lake.

Among the problems that put Deer Lake on the list were deformities or reproductive problems for wildlife. Another was excessive algae.

Report says farm runoff declining near Great Lakes

DETROIT (AP) - A report from the U.S. Department of Agriculture says farmers are cutting back significantly on the amount of soil and nutrients eroding from fields to the Great Lakes and neighboring waterways.    

The study estimates that methods such as no-till cultivation have cut in half the volume of sediments entering rivers and streams in the region, while phosphorus and nitrogen runoff are down by more than one-third.

Nutrients from farms and municipal waste treatment plants are believed to be one cause of rampant algae growth in the Great Lakes in recent years.

The study is based on a survey of farmers between 2003 and 2006.

Andy Buchsbaum of the National Wildlife Federation says the report shows progress is being made, but says more must be done to fix the algae problem.

Why does it take 40 years to clean up a polluted river?

Advisories warn people of dioxin contamination in the Tittabawassee river. Dow is responsible for releasing dioxin into the river.
Lisa Williams United States Fish and Wildlife Service

The Tittabawassee River has flooded three times already this year. Each time floodwaters carry dirt from the bottom of the river all over yards, basements, fields and parks.

This sediment is contaminated with Dioxin from Dow chemical’s plant in Midland. Dioxin has been linked to a host of health problems including cancer.

Aircraft chemical found in Great Lakes fish

New research finds that fish in the Great Lakes are contaminated with a chemical used in aircraft hydraulic fluids.

Researcher Amila DeSilva works for Environment Canada, which is like the EPA in the U.S.

She says there have been studies on a number of perflourinated chemicals. They’re used to make textiles, upholstery, paper, and many other things. Studies have shown these types of chemicals can have toxic effects in humans. But not much is known about a chemical called perfluoroethylcyclohexanesulfonate - or PFECHS for short.

DeSilva says no one has really studied whether it's toxic.

She wanted to see if PFECHS was in the environment, so she and her colleagues sampled water and fish in the Great Lakes, specifically lake trout and walleye:

“We were really, really surprised to find it in fish. Because, just based on the structure and our chemical intuition we thought, ‘okay, it would be more likely to be in water than in fish’ so when we found it in fish, when you find anything in fish, it’s a whole other ballgame because humans consume fish.”

DeSilva says other perflourinated acids are endocrine disruptors. That means they create hormone imbalances in humans, and they have other toxic effects. She says once these chemicals are released into the environment they don’t degrade, they just build up. That’s why use of some chemicals in this class is highly restricted in the U.S. and Canada.

Court of Appeals rules against Michigan CAFO operators

(USGS)

Large factory farms have lost a major court case in the Michigan Court of Appeals. The case involves farming operations with hundreds, sometimes thousands of animals. They are often called CAFOs, or Concentrated Animal Feeding Operations.

The appellate court upheld a lower court ruling that the state could require large confined animal feeding operations to get pollution discharge permits before opening. Farm groups challenged the state rule insisting they should only need a permit after releasing manure causing water pollution.  But today, the three judge panel disagreed:

We conclude that the DEQ was fully authorized to require CAFOs to either (1) seek and obtain an (federal) permit (irrespective of whether they actually discharge pollutants), or (2) satisfactorily demonstrate that they have no potential to discharge.  The circuit court  properly denied plaintiffs’ motion for summary disposition and granted summary disposition in favor of the DEQ.

Ann Wiowode  is the director of the Michigan chapter of the Sierra Club. She welcomes this week’s ruling. 

 “That is essential in insuring they’re not allowed to begin operation and potentially pollute the water  without going through proper review.”

But while she welcomes the decision, Wiowode says more work is needed to protect Michigan from water pollution connected to agriculture. 

 “We think the regulations are still too weak.  And based on our experience, the permits themselves have many things that could be improved.”   

The Michigan Farm Bureau expressed disappointment with the decision.
