More cities and businesses outside the Great Lakes basin want to take water from the Lakes. Great Lakes governors and provincial leaders are working on proposed new rules to control water diversions. Their proposal is expected to be released this month. Some say there’s a chance that more communities just outside the basin will get some water from the Great Lakes.

More cities and businesses outside the Great Lakes basin want to take water from the Lakes. Great Lakes governors and provincial leaders are working on proposed new rules to control water diversions. Their proposal is expected to be released this month. Some say there’s a chance that more communities just outside the basin will get some lake water. The Great Lakes Radio Consortium’s Chuck Quirmbach has the story.


Only a few communities outside the Great Lakes Basin currently get water from the Lakes, but some inland cities are growing and running short on groundwater supplies. One such city is Waukesha, Wisconsin. Waukesha is 25 miles away from Lake Michigan. The city is on the far side of the sub-continental divide that separates the Great Lakes basin from the basin where surface waters drain to the Mississippi river.

At the sunset pumping station in Waukesha, blue-painted pumps push groundwater from a large storage tank towards the homes of some of the city’s 65-thousand residents. Waukesha’s population has grown about 30 percent over the last two decades, so water utility general manager Dan Duchniak says the city is pumping more water than it used to…especially during dry periods when people water their lawns.


“When we did not have all the rain we had, we had our peak days around 10-11 million gallons a day – now around 12-13 million gallons a day. It goes up couple hundred thousand gallons per year.”


(gradually fade pump noise out)


No one in Waukesha is doing without tap water, but the groundwater table has dropped 300 feet over the last 50 years. And there’s another problem. Waukesha’s water supply is tainted by radium, a naturally occurring contaminant that could cause cancer. One of Waukesha’s long-term ideas for improving its water is to abandon the city wells and pump in up to twenty million gallons a day from Lake Michigan. In a complicated argument, hydrologists say Waukesha’s groundwater aquifer and the lake are connected anyway, so Dan Duchniak says a pipeline to the lake would not be a new withdrawal of water, and would actually help restore the original natural system.


“All we’re saying to make it real simple right now we have a vertical straw that is pulling water from the aquifer that has its tributary to the Great Lakes, we just want to take that water and make it horizontal for the better of the environment all around us.”


Duchniak has the ear of Wisconsin governor Jim Doyle. Governor Doyle is the new Chair of the Council of Great Lakes Governors. Among other things the council decides on water withdrawals from the Great Lakes. The governors of the eight Great Lakes states and leaders of Quebec and Ontario are expected to soon release a proposal called annex 2001. If passed, it will update rules on diverting great lakes water. Governor Doyle says he opposes sending water out of the Midwest, but he says short-distance diversions might be okay, if there’s a drop for drop return of clean water. Doyle acknowledges he needs unanimous agreement.


“There’s no reason for a governor of another state to approve even a small diversion unless they have some real confidence that the Great Lakes will be protected. That’s the way we protect it. Every single governor needs to approve.”


Governor Doyle says any change in diversion policy is years away. Still, environmental groups are closely watching for the annex 2001 proposal. Reg Gilbert is with Great Lakes United. He says before any more diversions are allowed, the plan should include more guidelines for water conservation. he says the lakes are too important to put them at risk by withdrawing too much water.


“Both our quality of life and a significant part of our economics come from a good functioning Great Lakes and if the rules for protecting it require it being difficult to divert water even those communities that want to divert that water might want to think twice and see it’s in the best interest of the whole region to have pretty strong rules… even if it makes it a little bit harder for some communities to get the water they need.”


Gilbert says he’s also looking for a plan that will pass muster with international trade courts that have questioned the legality of great lakes officials controlling the local waters. Gilbert’s hoping a lot of people will weigh in with their ideas during an upcoming comment period.

Preventing a Dangerous Microbe in Drinking Water

The EPA wants communities to do more to protect drinking water from a harmful microorganism. That could mean several changes for cities around the Great Lakes. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

The EPA wants communities to do more to protect
drinking water from a harmful microorganism. That could mean
several changes for cities around the Great Lakes. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:


Ten years ago, a Cryptosporidium outbreak in Milwaukee led to
the deaths of more than 100 people who had weakened immune
systems. The outbreak sickened 400,000 other people.


Since that time, Milwaukee has made 100 million dollars in water treatment plant
improvements. Milwaukee waterworks superintendent Carrie Lewis
says the EPA’s plan to make all drinking water treatment
systems monitor and guard against the microbe means some
cities face new construction at their water treatment buildings.


“Because one doesn’t easily add more barriers to
organisms like Cryptosporidium without adding more physical plant
to the water treatment plants.”


Lewis expects some cities to debate the cost and benefits of the
rule package.

Increasing Water Supply Safety

In the wake of the September 11th terrorist attacks, Americans are getting mixed signals from officials about just how safe their drinking water is. The federal government is trying to calm fears that terrorists might poison public water supplies.

In the wake of the September 11th terrorist attacks, Americans are getting mixed signals from officials about just how safe their drinking water is. The federal government is trying to calm fears that terrorists might poison public water supplies. But, at the same time the government and water utilities are asking the public to help keep an eye on reservoirs and storage tanks. The Great Lakes Radio Consortium’s Lester Graham reports.


Since the attacks, the head of the Environmental Protection Agency, Christie Whitman, has been traveling the country, assuring groups that water supplies are safe from terrorism. Speaking recently to a group of journalists, Whitman explained that security at water utilities has been increased and that water is now tested more frequently. And she said that given the size of most reservoirs, it would take a very large amount of any chemical or biological contaminant before any such attack would have an effect.


“It would be extremely difficult for someone to perform this kind of act, taking a truckload –and that’s what it would be, a tanker truckload– up to a reservoir and dumping it in, given the heightened security we have today. And that’s a security that’s not just being provided by the water companies, which it is, but it’s also citizen heightened security, believe me. People are calling in all the time when they see things that they think they shouldn’t be seeing near water supply systems.”


But, Whitman’s view is not shared by a number of experts in the field of terrorism prevention. Jim Snyder is a professor at the University of Michigan. He was a member of a team of experts that worked with the Defense Department to determine possible threats against public water supplies.


“There are a number of contaminants, several bio-toxins and a large number of chemicals that are more or less readily available that could be put into, let’s say, a ten-million gallon reservoir which could in amounts something between a backpack and a pickup truck could achieve a lethal dose of 50-percent. That is, 50-percent of the people who drank one cup would die.”


And Snyder adds, water contamination wouldn’t have to be lethal, just contaminated enough that it caused panic and made the water unusable. Snyder also points out that the tests that production chemists run on water would not detect the kind of contaminants terrorists would use. The first clue something was wrong would be sick or dead people.


EPA Administrator Whitman concedes that there are some contaminants that would not be filtered out or killed by disinfectants used in water treatment. but she says water systems across the U-S are prepared for most kinds of attacks.


“The vast majority of contaminants about which we’re worried, we know how to treat. We know what steps to take. And those where we’re not sure of what we need to do, we’re working with the CDC to develop a protocol to respond. And we’re sharing that information as we get it with the water companies to make sure even those small ones know what to look for and how to treat it if they find it.”


Besides the Center for Disease Control, the EPA is working with the FBI and the water utilities to prepare for the worst, while telling the public that there’s little to worry about. The EPA could have helped those water systems prepare earlier. The terrorism prevention team Jim Snyder sat on drafted a manual for water system operators, outlining security measures that could be taken. The EPA buried that manual in part because the agency didn’t want to unnecessarily alarm the public.


The water utility industry is working with the EPA to try to calm any fears the consumers might have. The American Water Works Association has held joint news conferences with Administrator Whitman, echoing the statement that poisons would be diluted or that it would take a tanker of contaminants to cause a problem. Pam Krider is a spokesperson for the American Water Works Association.


“When you get into a specific discussion about types of chemicals or quantities of chemicals, whether it’s a backpack or whether it’s a tanker, I mean, those are not as useful as discussing what are the processes that a utility has in place for monitoring what is and is not in its water, ensuring that they can provide safe, clean drinking water to the consumers within their city.”


So, the American Water Works Association is encouraging water utilities to step up testing water and quietly meet with emergency planners to prepare for the worst..


“What we have been discussing is the need for every utility to work very closely with local officials, to have a crisis preparedness and response plan in place, to have back-up systems in place, and most important, to engage their local community in keeping an eye out on the different reservoirs, storage tanks and treatment facilities and reporting any kind of suspicious activity that they might see both to the utility as well as to the police department.”


Water terrorism prevention expert Jim Snyder says simple things such as locking gates and posting security guards go a long way to discourage would-be terrorists from attacking a water treatment plant, storage tanks, wells or a reservoir. However, he notes. there’s little that can be done to stop a determined terrorist from contaminating a public water supply. And it seems that’s a message the EPA and the water utilities don’t want to talk about because it might worry the public.

Y-2-K’S Effects on the Environment

With less than a year to go before we reach the Year 2000, everyone
from computer experts to doomsday cult leaders is warning about the
Y-2-K bug. As Great Lakes Radio Consortium commentator Suzanne Elston
points out, no one knows for sure what’s going to happen because we
can’t imagine a world without computers.
