We really didn’t know what the level of public interest would be when FLOW started working with Joe VanderMeulen of Nature Change—as well as a variety of expert presenters, co-sponsors, and community partners—to develop a day-long summit devoted to Michigan’s septic dilemma.
Would people show up for a whole day to talk about old and failing septic systems? And sit still through an intestinal-bacteria presentation during lunch? Was our estimate of 150 registrants realistic?
Those questions were answered with a resounding “yes” on Wednesday, at our first-ever Michigan Septic Summit, which overflowed with more than 160 attendees and interest in:
- Exploring the latest septic system research on the human health and environmental risks,
- Learning about local and regional programs and regulations adopted in response to surface water and groundwater quality threats, and
- Fostering dialogue toward more effective and geographically extensive efforts to reduce risks from septic system waste.
On the same day that the U.S. Supreme Court heard a case that delved into septic tanks, Michiganders demonstrated we care about public health and water that’s safe for drinking, bathing, swimming, fishing, boating, and beachcombing. We care about finding equitable solutions to one of humankind’s oldest problems in communal living—disposing of human waste safely in Michigan, the only state that lacks a uniform sanitary code requiring periodic inspection and maintenance of septic systems—even though 30% of Michiganders rely on such systems.
The results of unregulated septic waste are devastating to Michigan surface water and groundwater. An estimated 130,000 septic systems in the state are failing, releasing 5.2 billion gallons of sewage annually into Michigan waters. Numerous Michigan rivers and lakes have detectable levels of fecal bacteria. Groundwater, too, is contaminated by septic wastes. And conventional household waste isn’t the only thing polluting our waters. Emerging contaminants like pharmaceutical residues and endocrine disruptors are also found in household wastes. Little monitoring is done to identify these substances in groundwater.
Some of the many highlights of the Michigan Septic Summit, which was streamed live by Traverse Area Community Media and available to watch now on TACM and Facebook, include:
Scott Kendzierski, Director of Environmental Health Services at the Health Department of Northwest Michigan, in his presentation on “Construction and Maintenance of Septic Systems,” identified an emerging issue in septic management: the seasonal rental scenario, in which a three-bedroom home with a septic system designed and permitted in the 1970s for perhaps six occupants is now accommodating more than three times that many people as vacationers, overtaxing an aging or possibly failed system.
Dr. Mark Borchardt, a research microbiologist at the U.S. Department of Agriculture’s Agricultural Research Service, Marshfield, Wisconsin, detailed a fascinating story of forensic detection in the case of disease outbreak in a Wisconsin restaurant with a new septic system that failed and contaminated the restaurant’s well and customers.
An audience member asked Borchardt about how high water levels affect septic-system effectiveness in deterring the spread of pathogens. He responded that ideally a system would put maximum distance between a septic drainfield and groundwater level; the higher the water table, the shorter the distance for microbes to travel from wastewater to drinking and surface water.
Jon Beard of Public Sector Consultants, a non-partisan public policy firm in Lansing, revealed perhaps the worst canine job in the world: Source-tracking bacterial contamination. He also shared a startling mid-Michigan survey result: 30% of residents with a septic system did not know they had one. And even more alarmingly, later presenters judged this figure to be too low.
Afternoon panels increased our understanding of the complexities facing local communities, all of which are united in the desire to protect groundwater from contamination. Rob Karner, watershed biologist at the Glen Lakes Association in Leelanau County, offered, “I have yet to find anybody who says, ‘I want to pollute the water. I want to drink contaminated water.’ It all comes down to this: Loving the water.”
FLOW’s Executive Director Liz Kirkwood echoed, “We’re having these conversations because we love the Great Lakes. Michigan is the Great Lakes State, and despite our infrastructure crisis, Michiganders really care about clean water. Wherever you are on the political spectrum, we’re here because we love these waters.”
In reflecting on the success of the Septic Summit, FLOW’s founder and famed environmental attorney Jim Olson, summed up the summit this way: “The need to come together never ends. A conference on an important matter concerning our water and the common good goes beyond the adoption of a particular septic system law or code.”
“It brings together a wide spectrum of people, diverse speakers with diverse backgrounds and something to say, and demonstrates the value of education, bringing people together—people who not only care about groundwater and the tens of thousands of failing septic systems, but also about the world and the water, environment, and quality of life in which they live,” Olson said. “I drove home in wonder over the conference and the inspiring feeling from being in a room of people who authentically care, share, and listen at a critical time for our communities and the world.”

What’s next in the wake of the Septic Summit? Stay tuned as FLOW and allies from around the state, including Michigan Clean Water Action, Michigan Environmental Council, and many others, intend to support more local and regional education and build backing for legislative action to develop and pass a statewide septic code.
