News to Us this month provides an update on the dioxane contamination case. Also, two new projects bring money to improve water quality in the Huron. Finally, read articles on two widespread water quality issues – PAH contamination due to coaltar pavement sealers and bacterial pollution from failing septic systems.
Judge grants local intervention in Ann Arbor dioxane pollution case In a precedent setting decision, Judge Connors granted intervention on legal negotiations associated with the Gelman dioxane plume to HRWC. Washtenaw County and the City of Ann Arbor were also granted intervention. As the Attorney General’s counsel stated, “…. in our experience we’ve never seen a circumstance where an environmental policy group or a public interest group basically has intervened and been a participant in the negotiation of a consent judgment, whether it’s the very first negotiation of a consent judgment, or in this case the fourth amendment to a consent judgment.” HRWC will represent the needs of the river ecosystem and recreational users.
$1.8M in federal funds to help protect Huron River watershed A significant award through a federal Farm Bill program is coming to the Huron. These funds will be used to protect natural and farmed lands and support farming practices that protect water quality. Efforts led by the Legacy Land Conservancy will be focused on the headwaters of the Huron in Oakland, Livingston and western Washtenaw counties. HRWC is one of many local groups involved in this unique partnership.
$675K design contract for new tunnel to Ann Arbor riverfront approved A major stormwater management and river access project in Ann Arbor now has the funding it needs to move forward. A tunnel will be built underneath the railroad tracks connecting pedestrians from Depot Street to the Border-to-Border trail and Argo park. This tunnel will also act as a release valve for stormwater which tends to back up and flood land and property in this low lying area where Allen Creek meets the Huron River.
Coal tar main source of toxicity in streams A recent study found that up to 94% of PAHs found in sediments in Milwaukee-area creeks and streams came from coaltar pavement sealants and that 78% of all samples had enough PAH content to be considered toxic. PAHs are a toxic class of chemicals that impact aquatic life and human health. HRWC has been working, in the face of mounting evidence, to ban the use of coaltar and other high PAH sealcoats to reduce the impacts of this unnecessary contaminant.

Aging septic systems fouling Michigan waters Did you know that Michigan is the only state that does not regulate septic systems? As many as 1.4 million of these systems exist within our state, very few are under any inspection and maintenance requirements. Sixty four rivers sampled in Michigan had bacterial contamination that was traced back to human sources. This is one of the biggest threats to Michigan waterways. HRWC has more information on this issue and how you can maintain your septic system here and will be investing in septic system education in Honey Creek, a tributary of the Huron considering impaired by the State for bacterial contamination.
HRWC and EPA have taken action recently pertaining to 1,4 dioxane – the chemical contaminating groundwater in the Huron River watershed. During road salt season, consider alternatives to reduce impacts to our lakes and rivers. Huron River residents and the Great Lakes received good news this week on funding for natural resource protection and recreation. All in this edition of News to Us.
Dioxane makes list of 10 toxic chemicals EPA giving closer look This past summer the act that governs the regulation of chemicals in the US underwent major reform which arguably reduced barriers to regulate toxic substances. The 30 year old act had made it notoriously difficult to regulate chemicals. Under the reformed act, EPA was tasked with selecting ten substances to evaluate first. 1,4-dioxane is on that list, meaning the chemical that is contaminating groundwater under Scio Township and Ann Arbor will undergo a thorough risk evaluation over the next three years.
Huron River Watershed Council and county take legal action on dioxane Last week, HRWC filed a motion to intervene in the Gelman case that would amend the consent judgement that put cleanup of the 1,4 dioxane plume contaminating local groundwater in the hands of MDEQ and Gelman Sciences. HRWC and Washtenaw County, who also filed a motion to intervene, argue that cleanup efforts have failed. Should the court choose to open the case again, HRWC would provide a voice for the river, aquatic life and river recreation.
Road Salt Sex Change: How Deicing Messes with Tadpole Biology In the season of ice and snow, Huron River residents will be bringing out the road salt. There is mounting evidence of negative impacts to rivers and lakes due to high salt concentrations. This article discusses new research findings that implicate road salt in developmental issues in tadpoles, particularly by altering sex ratios. For some alternative practices for safe sidewalks visit our tips page.
Coalition Applauds Great Lakes Investments in Bill Great news for the Great Lakes. The federal government has authorized another round of Great Lakes Restoration Initiative (GLRI) Funding. GLRI will provide $1.5 billion in funding over the next five years for projects that help restore our water resources. GLRI has funded projects in the Huron and throughout Southeast Michigan to the benefit of people, businesses and the natural resources.
Gov. Rick Snyder applauds Michigan Natural Resources Trust Fund board recommendations Several projects in the watershed were awarded grants from the Michigan Natural Resource Trust fund. These projects will advance trail systems in our area including the Washtenaw County Border-to-Border (B2B) trail segment from Dexter to Ann Arbor. Trail projects also build out the Huron Waterloo loop in Lyndon Township and a segment of the Iron Belle trail in Ypsilanti Township.
We need your help. The Michigan Department of Environmental Quality (MDEQ) has issued draft revisions to cleanup criteria for public comment. If accepted, the draft revisions will strengthen the State’s clean-up criteria for various pollutants. We urge you to submit comments asking the State to immediately adopt the draft. Business interests are opposing this draft even though they have had a seat at the table during development of the current draft revisions to 300+ toxins, including the 1,4 Dioxane. The public comment period runs through September 13th. More information about the revision is available on their website.
Please submit your comments to DEQ-RRDCriteria@michigan.gov
Here is some suggested text for comment.
“I am writing to express my support of Michigan’s Generic Cleanup Criteria Proposed Rules Revisions. This criteria is long overdue. In the interest of public health, I urge you to adopt the criteria. <your name, city/town, MI>”
For more information on the dioxane groundwater contamination in Washtenaw County please see these websites:
It is important to note that these revisions are long overdue. The State Legislature voted to complete these revisions by December 31, 2013. This and subsequent “new deadlines” have been missed, and 2 consecutive mayors of Ann Arbor have been promised these regulations would be changed by multiple “dates certain” that have passed us by. Please make written comment (or attend the public hearing in Lansing on September 12) urging the MDEQ to immediately adopt these public health regulations which are based on the best science agreed upon throughout the stakeholder engagement process.
Every voice counts! Please submit your comments today to DEQ-RRDCriteria@michigan.gov.
A new livery will open in the Huron next year! This month’s roundup of water news also includes articles on three contaminants we are watching closely here that affect the Huron River watershed – blue-green algae, Dioxane and coal tar based pavement sealers.
Former Mill Creek Sports Center in Dexter to become canoe livery
Exciting news! Dexter will be home to a new canoe livery. Occupying a vacant building on Mill Creek in the heart of downtown Dexter, Michigan native Nate Pound hopes to renovate and be open for business by paddling season in 2017. Long term plans include a climbing wall and/or bike rentals.
Blue-green algae adapting easily to rising carbon dioxide levels
Climate change will challenge all species to adapt to new conditions. Some will fare better than others. New research shows that blue-green algae, the type of algae that includes Microcystis – the algae that contaminated Toledo’s water system in 2014 – are likely to be particularly good at adapting. There are implications for water quality, drinking water and aquatic ecosystems as we move to a more carbon dioxide-rich environment.
The Green Room: The Ann Arbor Area’s 1,4 Dioxane Plume
HRWC Board Member and Washtenaw County Water Resources Commissioner, Evan Pratt, shares his thoughts on pursuing Superfund designation for the Dioxane plume contaminating the groundwater in Ann Arbor. Mayor Chris Taylor discusses the City’s involvement and how he is engaging with State and Federal elected officials.
HRWC’s campaign to ban coal tar based sealcoats throughout the watershed continues to make headlines. So far Van Buren Township, Scio Township, Ann Arbor, Hamburg and Dexter have passed ordinances with many other communities reviewing potential action. WEMU’s Issues of the Environment interview discusses the issue broadly and the Detroit Local 4 News spot highlights the recent ban in Hamburg Township.
Our monthly news roundup provides some watershed stories covering a fun event in Flat Rock and emerging research on the dioxane groundwater contamination in the Ann Arbor area. Bridge Magazine published an in depth article on the rising profile of County Drain Commissioners. And two new reports provide a look at how climate change is being addressed in planning efforts nationwide and is likely to impact public health in Michigan.
InsideOut exhibit brings museum-quality artwork to Flat Rock
Check out a unique art exhibit in one of the Huron River Watershed’s Trail Towns. For the second year in a row Flat Rock is displaying replica’s of fine artworks this summer through the DIA’s InsideOut program. This year you can see 8 paintings at locations throughout the town.
Professor says dioxane probably has reached Huron River already
Dr. Lemke of Wayne State University has been studying the Pall Gelman dioxane plume since 1998. He recently presented results of some modelling efforts that show a more nuanced range of possibilities for the movement of the contamination in Ann Arbor’s groundwater. The article illustrates further the need for better monitoring and solid planning for many potential scenarios about the path and time it will take for the dioxane to reach the river. (Note: While we think this is important news to cover, the headline here is misleading. There has been no evidence to suggest the plume has reached the Huron yet and the city of Ann Arbor regularly tests Barton Pond for dioxane.)
Why on earth is Candice Miller running for county drain commissioner?
This article discusses the role of county drain commissioners (sometimes known as water resource commissioners as they are in Washtenaw and Oakland Counties) and how this elected position is becoming higher profile in light of growing issues with water quality and water infrastructure. The Flint water crisis, combined sewer overflows, beach closings, and Great Lakes water quality are bringing much needed attention to our states aging water and sewer infrastructure.
Cities trying to plan for warmer, wetter climate
A researcher at the University of Michigan conducted a review of climate adaptation plans around the nation. These plans are intended to determine what is necessary to create a town or city that is prepared for the impacts of climate change and able to bounce back quickly from these impacts. While more communities are completing plans, they are falling short on implementation. How these strategies will be funded and who is responsible for carrying them out remains an area of adaptation that needs attention.
Changing climate conditions in Michigan pose an emerging public health threat
Additional new climate change research coming out of Michigan focuses on the human health impacts. “Michigan Climate and Health Profile Report 2015: Building resilience against climate effects on Michigan’s health” chronicles the many ways that more heat and more heavy rain events can affect our health. Respiratory diseases, heat related illnesses and water and vector borne diseases are areas of concern.
This edition of News to Us shares updates on Ann Arbor’s Dioxane contamination, climate change and coal tar sealcoat advocacy in the watershed. Also see the Huron making headlines as a retreat from the city and how one township is taking stock of its natural resources.
DEQ proposes tougher cleanup standard to protect residents from dioxane A large plume of groundwater under Ann Arbor and Scio Township is contaminated with 1,4-dioxane originating from the Pall Corporation. After years of pressure and mounting attention over the past few months, DEQ announced a proposed change to the dioxane drinking water standard in Michigan from 85 parts per billion to 7.2 ppb. There is still a 6 to 9 month process ahead of the proposed standard where it could change or be vetoed. Read more about the decades-long story in this piece from The Ann; Bearing Witness: Decades of dioxane. Or hear more from the acting director of the MDEQ at a Town Hall Meeting, April 18, 6-8:30pm at Eberwhite Elementary, Ann Arbor.
City and country: How metro Detroiters enjoy the best of both worlds We are blessed in southeast Michigan to have incredible natural resources nearby. The Huron River is cited as a destination for Detroit area residents to get away from it all. Four interviews show the diverse ways metro Detroiters access nature to relax and recreate.
Freedom Township Takes First Steps Toward Shaping Future Development to Protect Watershed Freedom Township is the most recent of several communities in the watershed to participate in HRWC’s Green Infrastructure project to map and prioritize natural areas. The Township intends to use the map to help inform future growth and development.
Record-breaking heat shows world ‘losing battle’ against climate change, Alan Finkel tells Q&A No one in southeast Michigan would argue we have had a typical winter. Warmer temperatures and limited snow events made it a little easier on all of us. It seems we were not alone. The climate has been making headlines again as February registered as the hottest February on record (global average) and by a huge margin. It is expected that temperatures will remain well above average for at least the next couple of months. Particularly worrisome about data from recent months is it shows the planet moving much more rapidly toward the maximum of 2.0°C warming agreed to by nations under the Paris Climate Agreement.
Watershed group wants ban on coal tar sealants HRWC Board Member Mary Bajcz has been championing efforts in Milford Township to increase awareness about the hazards of coal tar sealcoat products commonly used to maintain asphalt surfaces like driveways and parking lots. These sealcoats contain high levels of PAHs that can be harmful to people and river ecosystems. HRWC presented to Milford Township’s Board of Trustees who are now considering next steps.
Michigan’s water has had the attention of the national news for months now. While Flint dominates the headlines, there have been other news worthy water issues in this state including the Waukesha water withdrawal request hearing for a diversion of Great Lakes water to a location outside of the basin, and the very local issue of the spreading dioxane plume under Ann Arbor and Scio Township. The Huron also gets a nod in a national recreational magazine as a source of inspiration for one rising musician.
Dioxane in Ann Arbor’s groundwater: a slow-motion environmental disaster The dioxane contamination of the groundwater in Ann Arbor and Scio Township has been making headlines recently. The Pall Corporation is responsible for the contamination and the cleanup. The City has been pushing the Department of Environmental Quality to set stricter limits on dioxane levels for some time now without success. Current standards allow 85 parts per billion of dioxane. Ann Arbor would like to see standards require concentrations in the single digits, consistent with recent research on cancer risk.
Michigan Holds Hearing On Waukesha Plan To Divert Great Lakes Water – A hearing was held last week on what would be the first inter-basin transfer of Great Lakes water. The 2008 Great Lakes Compact is an agreement among Great Lakes states and Canadian provinces that requires strict criteria be met before permitting a diversion. HRWC’s Laura Rubin was on hand to provide comment along with several other water and policy experts from throughout the state. This will be a precedent setting ruling as it has the potential to open the door to more requests for Great Lakes water outside of the Great Lakes basin.
Why didn’t state officials heed the warnings in Flint? The Flint water crisis is all over the news. One storyline HRWC has been shining a light on is highlighted in this piece. The state’s environmental regulatory agency, the Department of Environmental Quality, has seen a steady decline in political support. The agency, along with other regulatory agencies, suffers under a culture that discourages staff from speaking up when issues are identified. Financial support, political backing and a culture that promotes adherence to regulations and transparency are necessary to avoid future Flints. Read more about Laura Rubin’s thoughts on this issue in her recent blog.
Chris Bathgate Goes Back to Nature Huron River watershed native Chris Bathgate is featured in Outside magazine. The acclaimed musician named the Huron River as one of his sources of inspiration. Imagine that! Bathgate talks about the importance of nature and quiet to his wellbeing and creative process. You may even “hear” the Huron on his latest album.
