Green slime returns to create crisis By J. Patrick Eaken Press Staff Writer news@presspublications.com

Oregon reacts to crisis

City closely monitoring drinking water Oregon has increased tests of its own water since high levels of a toxin were found in a water sample taken from Toledo’s Collins Park water treatment plant over the weekend. Toledo’s detection of microcystin, which can cause abnormal liver function in humans and animals, prompted Toledo to issue a three day ban on the use of its drinking water. Oregon has its own water treatment plant that provides water to many communities in the area, which were unaffected by the toxin affecting Toledo’s water. Microcystin is produced by blue green algal blooms in Lake Erie. The algae is believed to be fed mainly by phosphorus from agricultural runoff. Microcystin has been found in Oregon’s samples in the past, but not in amounts that can cause harm to humans, according to Oregon’s Public Service Director Paul Roman. In 2010, for example, microcystin was present in the finished (treated) water at 0.23 parts per billion (ppb) in Oregon, which was below the 1.0 ppb drinking water guidelines established by the World Health Organization, according to the Ohio EPA. “We will continue to monitor what’s going on in the lake in every aspect to maintain safe drinking water,” Oregon

Under a calm wind, that algae is more likely to stay floating on top of the water and not get into our intake. But nobody can control the winds.

Mayor Mike Seferian said at a committee of the whole meeting on Monday. Early testing Doug Wagner, Oregon’s superintendent of water treatment, started testing water samples once per week in early July, Roman told The Press before the meeting. “At this point, knowing what’s out there, Doug goes out three times per week – Monday, Wednesday and Friday. With what happened in Toledo over the weekend, Doug did additional tests on Saturday. Again, it was a `non-detect’ for microcystin in Oregon. Our water is safe,” said Roman. Toledo and Oregon started checking

for microcystin in the raw (untreated) water at the same time, said Roman. “Both entities are on top of seeing what’s in the raw water. When there are signs of microcystin, we start using activated carbon to treat it,” he said. The water source for Toledo’s and Oregon’s water treatment plants is Lake Erie’s Western Basin, which has been plagued by large blue green algal blooms for years. The raw water intake for each community is about a mile apart. “Our intake is a mile and a half into the lake. Toledo’s intake is just a little bit further north in the lake than ours, about two miles out. Our pump stations, which pump raw water to the treatment plants, are physically almost a mile from each other. We’re very close to each other in terms of our facilities,” said Roman. So why did Toledo’s water have a high level of the toxin and Oregon did not? “I don’t have an exact answer,” said Roman. “I don’t think anyone really does. I know we treat very similarly. I can’t speak for them. The testing is very delicate. There’s always some microcystin in the water. The question is, is it at a detectible limit?” Reduced capacity “I think we all just got caught off guard,” Wagner told council at the meeting. Continued on page 2

It’s almost like a sequel to a movie — one year ago, in the August 11, 2013 edition of The Press, a front page headline read, “Green slime arrives in waves.” We were told not to be alarmed — at least, not yet. But, maybe now is the time. Last week, about 500,000 residents who receive City of Toledo water had reason to be alarmed because their tap water was not drinkable for two days because it was contaminated by a toxin produced by an algae bloom in Lake Erie. The green water in the western basin of Lake Erie results from an invasive algae bloom. While not all algae is harmful, the type seen in the huge blooms in the western part of Lake Erie and other inland Ohio lakes can produce nerve and liver toxins, which are especially dangerous for pets, children, the elderly and those with comprised immune systems. Virtually all of Northwest Ohio’s groundwater drains into the western basin, and the water brings with it toxins from sewage systems and fertilizers from farm fields and residential yards. In addition, southeastern Michigan and Detroit contribute and there are other factors, like climate change. At the National Center for Water Quality Research, scientist Laura Johnson said algal blooms tend to widen and spread out, meaning this one could migrate to another part of Lake Erie. Without action, she Continued on page 2
