Well thought I would jump in here and add a couple of things which are public knowledge but kept under wraps as well as possible. The city of Toledo is the number one contributor to the problem in lake erie. They are now and have been for the last 50 years. The sewer system in Toledo has not functioned properly for the past thirty years. Toledo pays EPA fines each year because they "can't afford" to update and replace the sewer system. Studies over the past 15 years show that Maumee and Ottawa rivers contribute to more than 80% of the pollution in Lake Erie. In fact the last open EPA research from around 10 years back, claimed if those two rivers could be closed off, the big lake could clean itself within 5 years from the water flow
from the Detroit river. Toledo was one of the first cities to violate EPA regulations and tie their sanitary and storm sewers together to handle excess rain water and the city has been paying yearly fines for that for quite sometime. When heavy rains occur the entire sewer system including sanitary run directly into the river without going thru any treatment.
Now if you have paid any attention to the latest indirect comments the city has now gotten control of the chemical balance to make the water Ok to drink. Why was the balance allowed to get out of control? I know somebody screwed up. Have a friend that used to work in the area of water and sewer for the city and has said many times....todays water standards would not meet those set in 1960 as they have been lowered every few years to allow the water to pass. All I can say is I am certainly glad I got out of there many, many years back, and I have my own well and have for 40 years..No regrets!
