In January, HRWC staff and volunteers got together to celebrate another successful season of data collection. Call it a Water-Nerd-Fest, if you like, as we all geeked-out on the results from this year’s monitoring. The new twist this year was structuring our findings to focus on different tributary “Creeksheds,” similar to the way we have developed Creekshed Reports. Using that framework, we took volunteers on a tour of the watershed from the mouth at Lake Erie to the river’s named origin flowing out of Big Lake.
Stevi Kosloskey and I talked about results from the Water Quality Monitoring Program, in which we sample stream water chemistry and track stream flows. The results from 2016 and past years really provide a tale of three different watersheds: the lower section is characterized by lots of developed land which corresponds with generally poorer water quality. The middle section also has some development, but is also mixed with forest and agriculture lands, and much effort and resources have been invested in treating urban runoff (see Summer 2016 and 2015 newsletter articles for more detailed analysis of the impacts of those investments). Subsequently, we saw our lowest phosphorus concentrations from that region in 2016 and the bacteria levels are strongly declining as well. Upstream in the Chain of Lakes region, there is much less development and large areas of protected lands, and we see generally better water quality, though there are signs of decline to keep our eyes on.
We also discussed findings from River Roundup, habitat and Bioreserve programs. Sign-up to volunteer for these in 2017 so you can join the fun, learn more about the watershed, and get your science geek on!
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.
Lively Discussions Lead to Learning
Over 60 people from the Huron River watershed and beyond gathered at the Freedom Township Hall to learn about Community Techniques for Protecting Water Quality. Elected and appointed officials from six townships attended the December forum on the vital role local governments play in protecting our region’s lakes, rivers, and streams and the natural areas that contribute to their quality. Attendees also included members of a variety of water protection groups and interested citizens, some driving as far as 200 miles from northern Michigan and Ohio.
Planning for community growth that protects natural areas is the key to ensuring clean water and vibrant communities for residents, businesses and farms. The goal of the forum was to share concepts, ideas and programs and to provide participants with an opportunity to learn from each other what works.
Harry Sheehan, the Deputy Water Resource Commissioner from Washtenaw County led the morning with an important overview on protecting water quality. Then Sally Rutzky and Erica Perry, Planning Commissioners from Lyndon and Webster Townships, communities HRWC has worked with to develop Green Infrastructure maps and plans, shared challenges and unique solutions to water and land protection issues. Monica Day, Michigan State University Extension educator, connected local water quality protection to statewide issues on the news like the Flint water crisis and algae problems in Toledo.
The forum was organized by HRWC, Mchigan State University Extension, Freedom Township, Pleasant Lake Property Owners Association, Michigan Lake and Stream Associations, the Washtenaw County Water Resources Commissioner, Citizens Respecting Our Waters, and Washtenaw County Emergency Management.
Forum presentations are available at HRWC’s Green Infrastructure page.
HRWC has received funding from the Knight Foundation to provide Green Infrastructure Planning Services to local governments. This includes a workshop where residents and officials map out their community’s natural areas and greenways, an audit of their zoning ordinance, master plan and other policies, and technical support in enhancing policies to protect water quality and natural areas. If your local government would like Green Infrastructure Planning Services, email Kris Olsson or call her at (734) 769-5123 x 607.
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.
Aquatic insect sampling on the Huron River and its creeks
Thanks to 154 volunteers who contributed approximately 600 volunteer hours, the October 2016 River Roundup was a great success! As always, HRWC 100% guarantees good weather for its volunteer events or your money back. We were once again able to fulfill that promise!
It was a very full house here in the HRWC conference rooms before the 18 teams split up and traveled to 36 different creek and river locations across the Huron River Watershed to assess the aquatic benthic macroinvertebrate community. This study is one of the most effective ways that HRWC has to understand how the water quality of the river and creeks may be changing. From the data collected at this semi-annual event, we are able to keep abreast of the health of our waterways throughout the watershed. You can see a summary below, or detailed results in the October 10 River Roundup Report.
Current Watershed Health
HRWC gives a rating to each site that we monitor (Excellent, Good, Fair, or Poor). The graph above shows this breakdown for the 61 locations that HRWC considers representative for the watershed. The detailed River Roundup report gives the site condition for each location.
Overall, the health of the watershed as judged by our macroinvertebrate sampling is holding steady, though there are particular areas getting worse or better. 30 sites have had no statistically significant changes over time, and 4 sites are too new to make this judgment.
Fifteen sites are declining, and these include locations on Norton Creek, Horseshoe Creek, and Honey Creek (Washtenaw Co). Ten of the declining sites are in Livingston County, 3 are in Washtenaw, 1 is in Oakland, and 1 is in Wayne.
Twelve sites are significantly improving. Eleven of the improving sites are in Washtenaw County, including locations on Mill Creek, Malletts Creek, Fleming Creek, and the Huron River. One site is improving in Livingston County (Mann Creek at Van Amberg Road), and 1 site is improving in Wayne County (Woods Creek at the Lower Huron Metropark).
There were a lot of highly diverse samples collected this season. The team at Pettibone Creek: Commerce Road in Milford collected the most diverse sample ever taken at the site (sampling started here in 2001).
Two sites on South Ore Creek were diverse enough to pull these creeks out of a statistically significant decline and into the “declining but not significantly so” range.
The sample taken at Davis Creek off of Silver Road was the best sample taken in about 8 years.
For some teams, sampling conditions were difficult. The Huron River was running fast and deep after the area received heavy rain just a few days before the event started. The sample taken at the Huron River at Zeeb Road was particularly bad and far outside the range of normal variation. Based on the volunteer’s feedback and the difficulty of sampling the river, this sample was marked as an outlier and will not be included in the long-term record for the site.
Want to learn more about the data that HRWC collected this past year? On January 19th at 6 pm at our office on 1100 N. Main Street, HRWC staff will present results and interpretation for all of the field projects conducted within the past year. Good indoor weather guaranteed!
Do you consider yourself a Michigander, or aspire to be one? Then you should brave the cold and join the Winter Stonefly Search on January 21. It is like the River Roundup, only much snowier and usually colder. Good weather guaranteed or your money back… but of course these events are always free! You can register for the event here.
The 2016 Water Quality Monitoring Program season wrapped up at the end of September, and now I spend time compiling the data for analysis. With the help of 60 volunteers between April and September, we gathered water samples for chemistry analysis at 37 sites throughout Washtenaw, Wayne, and Livingston Counties. Flow measurements were also taken at several of those sites. Monitoring sites are visited up to 12 times during the season, and it would be impossible to gather this much information, or visit as many sites, without the help of volunteers. We are able to gather critical watershed data, as well as keep eyes on the Huron River and its tributaries for potential problems and risks such as erosion and pollution. I am proud of this program, it allows citizens to become actively involved in protecting the Huron River watershed and the water we rely on for so much. Thank you, volunteers, for helping us.
Mark your calendar for January 19, 2017 at 6:00pm and come to our Volunteer Appreciation and 2016 Field Season Results Presentation.
HRWC’s commitment to compiling and sharing noteworthy water-related news continues. This month’s News to Us covers the recent listing of Lake Erie as impaired waters, problems associated with low density development, a great river recovery story and some tips on good river “housekeeping” for autumn leaves.
Conservation Groups Applaud Michigan’s Inclusion of Lake Erie in Impaired Waters Report
Last week the Michigan Department of Environmental Quality listed western Lake Erie as impaired waters under the Clean Water Act. Environmental groups have been advocating for this for some time now as it will allow for further research, funding and action to address the nutrient pollution that leads to toxic algal blooms in Lake Erie. This is very good news for this Great Lake. Many are pushing for Ohio to follow suit.
Is the Infrastructure ‘Time Bomb’ Beginning to Blow?
It may not be immediately obvious, but low density development—what we see in suburban and rural areas where homes are built on large lots far from city centers—is not good for waters and watersheds. Here at HRWC we prefer high density development in a few areas as opposed to low density development everywhere. This article highlights one of the problems associated with sprawling development. “Low density housing cannot pay the bills.” The tax revenue is too low to cover the cost of infrastructure maintenance like roads, sewer and water necessary to serve these developments. When this infrastructure fails, the environment suffers. Check out our Smart Growth publications to learn more.
Taking Down Dams and Letting the Fish Flow
Last issue we shared an article about the human safety benefits of dam removal. This heartening story shows how quickly an ecosystem can rebound after dam removals. Three dams were removed on the Penobscot River in Maine in 2012 and 2013. Just three years later, huge numbers of native migratory fish have resumed their migration up the river—a trip they have not been able to make for nearly 200 years!
Leave The Leaves–Putting Organic Waste To Work
Leaves and grass that make their way into waterways add excess nutrients and use up valuable oxygen as they decompose. Local Master Composter Nancy Stone gives advice on how to utilize fall yard waste to maximize the benefits of fallen leaves. Leaves can be used in your yard to improve your soil and reduce weed growth. Nancy recommends mowing the leaves into your lawn. Mulching leaves can also reduce the greenhouse gas methane. Give this interview a listen as you are getting ready to clean up fall leaves. For more tips on river friendly home care visit our pollution prevention page.
Breaking news here at HRWC headquarters: we have been awarded a grant to implement our Honey Creek Watershed Management Plan! In 2012 -2013 we researched within the Honey Creek watershed to identify problems. Primarily, we scoured the watershed looking at bacteria levels and fingerprinting their sources. Honey Creek’s poor water quality is due to high bacteria levels, which can threaten human health.
Our research led us to some recommendations on how to protect and restore the area in ways that address the most critical issues. We are pleased to report that the Department of Environmental Quality has provided funding for this work within the Honey Creek watershed. Our Honey Creek project starts this autumn and will end in autumn 2019.
With this grant, we will:
- Hire canine teams (dogs!) to sniff out sources of human sewage waste in 2 key areas of the watershed. Once the dogs help us identify specific areas with septic issues, we will work with Washtenaw County and property owners to help them address problems. We will also do homeowner outreach on ways to maintain septic systems.
- Scoop that poop! We will raise awareness of the importance of removing pet waste from yards and parks, and install pet waste pick-up stations. Pet waste is one of the predominant sources of bacteria in Honey Creek.
- Mark 1,000 storm drains and hand out door-to-door flyers to raise awareness of their direct connection to Honey Creek and what people can do to capture and reduce runoff pollution.
- Identify farmers in the Middle Huron watershed for a Farmer Advisory Council (FAC). The FAC will advise HRWC and project partners on future plans to address bacteria and nutrient reduction from agriculture including innovative approaches such as “pay for performance” subsidies for nutrient and bacteria reduction practices.
For questions about our new project, contact Ric here.
This project has been funded wholly or in part through Michigan Department of Environmental Quality’s Nonpoint Source Program by the United States Environmental Protection Agency.
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.
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.
