Members of Congress are pushing a bill that would stop the U.S. Environmental Protection
Agency from allowing sewage overflow to be released into lakes and rivers. The Great Lakes
Radio Consortium’s Lester Graham reports:
The EPA is considering a proposal that would allow some sewage treatment plants to blend
partially treated sewage with fully treated wastewater to dilute and then release it into waterways.
Environmentalists don’t like the idea. Now they’re getting support from some members of
Congress.
Adrianne Marsh is a spokesperson for one of the sponsors of the bill, Michigan Democrat Bart
Stupak…
“Well, it’s important that this bill is being introduced because it sends a strong message to EPA
that we will not stand for this proposal to be enacted and roll back 30 years of water protection.”
The bi-partisan bill called “Save Our Waters from Sewage Act” comes on the heels of a letter
signed by 135 members of Congress, urging the EPA to scrap its sewage blending proposal.

Officials at the Environmental Protection Agency are considering a new policy for sewage treatment plants. Many environmentalists say if the policy is adopted, it will lead to increased water pollution and greater risk to public health. The Great Lakes Radio Consortium’s Mark Brush reports on the debate over sewage blending:
(sound of water in sewer)
Some sanitary sewers are tied in with storm sewers. So when there’s a big rainstorm, or when there’s a fast snowmelt, all that water can inundate some sewage treatment plants. To tackle this problem, some treatment plants have adopted a practice known as “blending.” The excess sewage is re-routed around the slower parts of the treatment plant. The dirty water is then mixed with the water that’s been cleaned. It’s sometimes given a shot of chlorine, and then released into creeks, rivers, and lakes.
Kurt Heise oversees the operation of a sewage treatment plant on the Detroit River. He says the practice of blending is necessary in order to keep the plant from being overwhelmed.
“When you have a wet weather event, an extreme wet weather event, if we were to allow all of that combined water in through the normal process the treatment process would be ruined.”
Sewage blending has been around for a long time. To plant operators, it’s a necessary step in handling large amounts of dirty water. But to some people, blending is not seen as a good option. They want the practice to stop.
Instead, they say, cities should invest in their systems to make sure they can fully treat all the water that comes to the plant. Kurt Heise says, if his plant were required to do this, it wouldn’t make sense economically.
“It would almost result in doubling the size of our plant and spending just untold amounts of dollars for an event only happens a few times a year.”
Sewage treatment plant operators say you have to weigh the costs and the benefits before spending hundreds of millions of dollars on expanding the treatment plants. The decision of whether or not to allow blending has been left up to state and local regulators. But recently, the U.S. Environmental Protection Agency has weighed in on the subject. And ever since they suggested new guidelines for allowing blending, environmentalists have been critical of their plan. Mike Shriberg is the Great Lakes advocate for the Public Interest Research Group. It’s an environmental consumer activist organization.
Shriberg says the draft blending policy, the way it’s written now, is too broad. And will allow the practice of blending to become routine.
“Our fear is that when you’ve got a treatment plant that uses blending, they’re never going to upgrade to full treatment sewage. And so if a treatment plant is allowed to blend they’re not going to go up to full treatment capacity they have no incentive to do that anymore. It’s sort of the cheap way out.”
Sewage treatment operators say blending is better than seeing the raw sewage overflow into waterways. And they say it’s better than spending large sums of money to fix a problem that only occurs a few times a year. But critics say the EPA doesn’t have a good handle on how often blending is used, and what kind of health risks are associated with the practice.
Some initial studies have been done on blended sewage and how it might affect public health. Joan Rose is a water microbiologist at Michigan State University. She’s written a report on the health risks associated with blended sewage.
“So what I found was that if people were actually swimming in the water and there was a discharge of a blended sewage upstream, that their risk of getting sick, actually getting sick with a virus or a parasite was about a hundred times greater – when there was a blended discharge as opposed to if the water was fully treated.”
Rose says some of these viruses, such as Hepatitis-A, are highly contagious. At this point, there are no good estimates on how many people get sick from blended sewage each year. It’s never been studied, so the impact of blending on public health is unclear. Ben Grumbles is the Assistant Administrator for water at the EPA. He says the EPA is considering the billions of dollars at stake in expanding the nation’s sewer treatment plants versus the risk to public health.
“What we’re trying to do is to clarify what’s legal and what isn’t legal and to recognize the economic realities that sewage teatment plants face across the country in terms of their infrastructure needs, but foremost and above all what leaves the facility has to meet Clean Water Act permit limits.”
But the Clean Water Act permit limits don’t measure all the viruses, bacteria, and parasites found in blended sewage. And so some environmentalists and scientists say meeting the limits doesn’t necessarily mean protecting public health. Grumbles says officials are still reviewing the tens of thousands of comments they received after releasing the draft blending policy.
He says he doesn’t know what the final rule will look like, or if they’ll issue a rule at all. One thing is likely, if the policy is finalized the way it’s written now, it’s expected that environmental groups will take the EPA to court.

The Environmental Protection Agency is finalizing a policy that will allow sewage treatment operators to send largely untreated sewage directly into rivers and lakes. It’s a cost-savings effort pushed by the Bush administration. The Great Lakes Radio Consortium’s Lester Graham reports:
The process is called blending. If too much sewage is coming in to treat completely, this policy allows operators to “blend” mostly untreated sewage with already treated waste water, then release it into the waterways. That saves the federal government money by not having to pay for sewage plant expansions.
Environmentalists don’t like it. Nancy Stoner is with the group Natural Resources Defense Council.
“They’re saying that they’re going to save money by providing less treatment now even though that pushes the cost onto the public by contaminating our drinking water supply, by killing fish, by contaminating shellfish so it cant be sold, by closing beaches.”
The EPA says blending untreated sewage with treated sewage dilutes it so that it meets federal standards. The agency also argues that the policy merely sanctions a practice that already happens every time a sewer system gets swamped by heavy rains.

A Toronto researcher says most communities are underestimating a potential source
of cheap electricity – raw sewage. The Great Lakes Radio Consortium’s Karen Kelly reports:
University of Toronto professor David Bagley collected waste water at a North
Toronto water treatment plant. He took the sewage into his lab, dried it and
then burned the solids to see how much energy they produced. He estimates the
energy produced from sewage at three treatment plants could produce more than
100 megawatts of electricity. That could be enough to keep a small town going
for a year. But Bagley says few take advantage of this resource.
“Our measurements show that there’s enough energy that we should be able to
completely offset the electricity needed to run the plant, and have extra
left over the send back to to the grid.”
Bagley finds communities are reluctant to invest in the equipment they’d
need to convert sewage into power. But he’s hoping to to design a cheaper
and more efficient system so more people can get the most out of their sewage.

The proposed Annex 2001 agreement is the subject of lively debate as to whether it will help or hinder the conservation of the Great Lakes (Photo by Jeremy Lounds)
Officials from the eight states and two provinces in the region have proposed two agreements that would regulate the use of Great Lakes water. They’re known as the Annex 2001 Implementing Agreements. Response to the proposed agreements has generally been positive. But for some in the region, they’re seen as a slippery slope.

Officials from the eight states and two provinces in the region have proposed two agreements
that would regulate the use of Great Lakes water. They’re known as the Annex 2001 Implementing
Agreements. Response to the proposed agreements has generally been positive. But for some in
the region, they’re seen as a slippery slope. Great Lakes Radio Consortium commentator Suzanne
Elston is worried that the proposed agreements will lead to unlimited diversions in the future:
In theory, the proposed Agreements are supposed to provide a framework for using the water of the
Great Lakes. In reality, they’re about as leaky as a sunken lake freighter. The framework’s
there, but they fail to impose an overall limit on the volume of water that can be diverted,
or who can take it.
Not only that, but proposals to take less than a million gallons per day out of the basin won’t
require a region-wide review, several of these smaller withdrawals could eventually add up to a
whole lot of water. And whether it’s one large pipe or a lot of tiny ones, the end result is the
same.
Given that the Great Lakes basin contains 20% of all the fresh water on the planet, diverting
some of it shouldn’t be a problem. Unfortunately, only 1% of that water is renewed each year.
It would be a good idea to first figure out how much water can be taken without disrupting the
ecological balance of the Lakes. Only once that’s been done should we be looking at allowing
large-scale withdrawals.
And then there’s the threat of trade challenges. Each state or province that approves a water
taking permit won’t be paid directly for the water. Instead they’ll recieve a funding to upgrade
sewage treatment plants or to improve local habitats for example. Recently, a Canadian non-profit
asked for legal opinion about the Agreements. The response was that linking the approval process
to funding for public works basically means that the water is being sold, and under the terms of
NAFTA, once you’ve identified something as a commodity, you can’t restrict its sale.
Canadians should be particularly concerned about these Agreements. The Council of Great Lakes
Governors drafted them. And although the premiers of Ontario and Quebec have signed off on them,
in the end, neither province has the right to veto the decisions made by the Council. In my book,
that’s a lot like being invited to dinner and then being asked to leave before the main course.
And the reverse is true too. If Ontario or Quebec approves a withdrawal, states in the U.S.
wouldn’t have the ability to veto the decision. We share these lakes. If we are all called on
to protect the Great Lakes, then we all need to have an equal voice. That’s why our federal
representatives in Washington D.C. and Ottawa need to draw up a binding international agreement
on water withdrawals.
If nothing else, the proposed Agreements have made it clear that the Great Lakes must be
protected. And with 40 million users already relying on this irreplaceable resource, we clearly
need something better than these Agreements currently have to offer.

Sewers like these were leaking this spring in Milwaukee according to a task force employed by the mayor. He says fixing the problem may be expensive. (Photo by Bob Smith)

One of the biggest dumpers of raw sewage into the Great Lakes this year may be heading toward a solution that puts the clean-up burden on local citizens. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:
Several cities dumped sewage into the Great Lakes during heavy rains this spring and summer. Milwaukee’s overflow total was about five billion gallons. A task force set up by Milwaukee’s mayor concludes much of the problem came from rainwater leaking into the sewer system through illegal hookups and cracked pipes between homes and sewer mains. Mayor Tom Barrett says reducing the so-called infiltration and inflow, or, I and I, will be expensive.
“Well, we’re obviously going to have to put more dollars into I and I in Milwaukee. The city has done that, we’re doing more in this budget, we’re going to continue to do more… I think each of the communities is going to have to face that issue.”
The “communities” are the roughly 30 smaller cities that use the Milwaukee sewer system. Wisconsin’s attorney general is trying to ge the city and suburbs to work together. Milwaukee and many other Great Lakes cities are also asking the U.S. government to spend more money on reducing sewer overflows.

Sewage overflows during heavy rains have long been implicated in
illnesses in people. For the first time, the Environmental Protection
Agency has come up with an estimate of just how many people are getting
sick from swimming at contaminated beaches. The Great Lakes Radio
Consortium’s Tracy Samilton reports:
The EPA estimates that somewhere between 3,500 and 5,500 beachgoers get sick
every year when untreated sewage is flushed into rivers, streams and lakes
by heavy rains. The EPA’s Ben Grumbles says the report is another reason
for cities to fix their aging sewage systems – despite the high cost.
“And it can literally add up to hundreds of millions, a couple of billion dollars, for
very large cities, to fix the problem for the long-term.”
Grumbles says many communities can avoid that bigger expense by investing
in new technologies to better manage existing systems – and keeping pipes
well-maintained and free of debris.
Environmental groups say they hope legislators are listening. Congress just reduced
the fund from which communities can get loans for sewer projects by 500 million dollars.

Municipal sewer plants are sometimes blamed for high E. coli bacteria counts
that close beaches to swimmers. Some cities are working to find better ways to treat the
water and put it back into nature. The Great Lakes Radio Consortium’s Chris McCarus
reports:

A typical summer day by the lake: SUVs pull boats on trailers. People saunter from an
ice cream shop to the city beach. Jet skis and water skiiers slice through the waves.
Carpenters raise trusses on homes being built into the remaining lakefront lots.
Just a few years ago it seemed towns like this were just for loggers and locals. But now
people are flocking to the lakes around the Midwest and staying there. And that’s putting
a strain on local sewer plants.
(sound of machines inside the water treatment plant)
For 40 years, the treated waste water from the Boyne City, Michigan sewer plant has
been released into the big lake it was built on…Lake Charlevoix.
“It’s located right adjacent to a public swimming beach, park, marina and some valuable
waterfront property. We are only a block off the downtown district.”
Plant manager Dan Meads wants to stop mixing the end product with the water where
tourists and the locals swim and play. He tests daily for E. coli bacteria. He
doesn’t want anyone getting sick. But it’s still a concern, and there are other concerns.
In recent years, the United States Geological Survey has reported on new kinds of
contaminants that they’ve found in ground and surface water. The USGS says treated
wastewater from sewer plants can contain hormones from birth control pills, antibiotics,
detergents, fire retardants, and pesticides.
USGS microbiologist Sheridan Haack says the effects of all these compounds are still
unknown. Most are found in tiny quantities, but combined they could cause any number
of chemical reactions.
“There are many different chemical structures and it would be very difficult to state for
all of them what we would actually expect the environmental fate to be and how they
would actually be transported through the environment.”
Haack says the medicines people take don’t disappear. They eventually leave the body
and are flushed down the toilet. Those drugs have been tested for safe human
consumption, but the question is: what happens when those chemicals are mixed in with
industrial waste, accidental spills and nature’s own chemical processes? Haack says they
just might come back around to hurt humans, fish and wildlife.
The Boyne City solution is to build a new wastewater treatment plant two miles from the
beaches up the Boyne River. Officials say contaminants will be diluted by the time they
flow back down into Lake Charlevoix.
(sound of the Boyne River)
Larry Maltby volunteers for a group called “Friends of the Boyne River.” The group
doesn’t like the city’s plan to discharge treated wastewater directly into the river. It wants
them to consider some non-traditional methods. They say the new sewer plant could run
a pipe under a golf course or spray the treated water on farm fields… or let it drain into
wetlands to let nature filter it out.
“It will seep into the soils which are very sandy and gravelly underneath the golf course
and then the filtration through the ground will have a great deal of effect of continuing to
purify that water. Much more so than it would be with a direct deposit, straight into the
surface waters of Michigan.”
Lawyers for the Friends of the Boyne River have appealed to the state dept of
environmental quality and filed a lawsuit.
But wastewater treatment plant manager Dan Meads says the city doesn’t want to please
just one group and end up angering another…
“There isn’t any guarantee that you can satisfy everybody. We think we have the best
option available.”
As municipalities are short on funds and personnel, they don’t want to wait for decades
for the perfect solution. Still, nobody wants any amount of pollution to affect their home
or their recreational area.
Sheridan Haack with the USGS won’t take either side in this dispute. She says not only
are the dangers from contaminants unknown, the best way to deal with them is unknown.
“I am not aware of any consensus in the scientific community on the nature or types of
treatment for this broad range of chemicals.”
In the meantime… communities such as Boyne City have the unenviable task of trying to
dispose of their residents sewage without polluting the beaches, the fishing, and the
environment that brought folks there in the first place.

A new report says the nation’s beaches were closed a record number

Great Lakes Radio Consortium’s Rebecca Williams reports:
The Natural Resources Defense Council releases a beach report every
year. It’s based on data from the previous summer. The NRDC says,
last season, there were more than 18,000 closings or advisories –
that’s more than any summer in the past 14 years.
Nancy Stoner is with the NRDC. She says health officials are doing a
better job of testing beaches and that has lead to more beach closings.
Stoner says it’s good that more beaches are being tested… but she
says most communities are failing to control pollution sources.
“We know where the problem comes from and that’s contaminated
storm water and sewage. One of the big problems this year is that the
Clean Water State Revolving Fund has been slashed in the White
House budget. And Congress has not restored that funding.”
Stoner calls the funding critical for cities to repair aging sewer and
storm water systems. The NRDC is calling on Congress to restore the
cuts to the fund in the fall.

A good midwestern summer storm can dump a lot of water in one
place. Sometimes there’s so much rainwater, it floods into the
underground pipes that carry sewer waste. It mixes with untreated
sewage and washes into lakes and rivers. Cities around the country
are each spending millions of dollars to solve the problem. In one
city, officials are encouraging people to build “rain gardens.” The
perennial gardens are designed to hold rainwater and let it seep
gradually into the ground. The Great Lakes Radio Consortium’s
Stephanie Hemphill reports:
The sewage treatment plant sits right on the waterfront of Lake
Superior in Superior, Wisconsin. You can see treatment tanks and
pump houses at the edge of the lake, and lately you can also see
gardens. They’re demonstration plots, showing how homeowners
can help solve a serious problem. Each garden is like a shallow
bowl; about six inches lower than the surrounding ground. The
buildings next to the gardens have down spouts that carry water from
the roofs right into the gardens.
Charlene Johnson is creating these rain gardens. She digs away the
surface soil, adds compost, and then plants native grasses and
perennials.
“We’ve got the Golden alexander starting to bloom, this one has
purple coneflower, Green-headed coneflower, Cardinal flower, the
bonisette.”
They’re pretty and they’re all plants that can live with a lot of water, or
just a little. Johnson says they do a much better job of holding onto
rainwater than a regular lawn, because they have deep roots.
“You know, the average lawn is about 1-2 inches. Therefore you’d
only have one or two inches of roots. Roots equal storage capacity.
Also as the roots penetrate through the ground, they die back, and
those holes can also be used for storm water retention.”
That helps keep some of the rainwater from rushing into the sewer
system. Johnson would like it if every yard in Superior had a rain
garden. The ideal size depends on the size of the house and the
type of soil in the yard, but they’re usually about the size of a small
patio.
A lot of us are building water gardens these days – small pools or
ponds – but a rain garden is different. It’s not designed to hold water
or goldfish. It’s designed to absorb big rains and let them sink slowly
into the ground.
“Plants and soil naturally cleanse pollutants from water. By the time it
recharges into the groundwater aquifers, the water is essentially
clean. ”
Charlene Johnson says rain gardens cost about the same to build as
any other perennial garden – between $3 and 5 a square foot. Most
of that is to buy plants, so it’s a one-time purchase. Even if it’s not
that expensive, you might be thinking it’s still a lot of money just to
help the city save on treating sewage, but Johnson says it can pay off
in the long run, because keeping rainwater out of the sewage
treatment system, means the city won’t have to treat as much
volume. That saves money and keeps your monthly sewer bill lower.
Your rain garden will also help the environment by keeping the rush
of water from overwhelming the sewer system and sending it into the
river or lake near your home.
On the other side of town, Jan Murphy says she loves her rain
garden. She built it seven years ago when she built her bookstore
and coffee shop in Superior.

“We’ve had ducks. That’s a baby redwing blackbird I believe, it’s
been very delightful. We’ve had lots of little critters in here from time
to time. ”
Runoff from the bookstore parking lot flows into the garden, where the cattails and other
native plants clean it up before it seeps into the city storm water system. Now, if you and
your neighbors build rain gardens, it still might not completely solve your city’s problems
with storm water runoff, but the experts say it can help.
Kurt Soderberg directs the Western Lake Superior Sanitary District in
Duluth. He says rainwater picks up all kinds of pollution as it flows
across parking lots, streets, and yards, and eventually into rivers and
lakes.
“Rainwater is a big impact on water quality. Whether it’s sediment
washing into the lake, whether it’s fecal coliform going into the creeks
and the lakes, there are a whole lot of reasons why you want to stop
storm water from rushing into the natural bodies of water. ”
Soderberg says rain gardens can filter and clean the water before it
reaches lakes and rivers. A lot of cities are spending millions of
dollars each, trying to keep storm water from overwhelming the sewer
system. Soderberg says rain gardens could be part of the solution.
