Toledo and other communities are spending more money to treat their water because of toxins produced by algae blooms.
Officials in Ottawa County are considering a fee increase next year to cover the added expenses in testing and treating the water.
Toledo plans to spend an extra $1 million this year to combat toxins that can kill animals and make people sick.
This change comes after one township told about 2,000 people not to drink or use the water coming from their taps because of the amount of toxins spiked last month.
Earlier in September, residents from Carroll Township were warned against drinking the water for two days after a sample collected revealed the microcystin toxins exceeded Ohioâ??s EPA regulations.
Carroll Township handed out bottled water during the alert while officials were working to switch water system, so they could flush the lines.
Officials advised that only healthy adults use the water for bathing, washing hands, washing dishes and doing laundry but warned that skin irritation could result from exposure to the water.
Officials also urged residents to seek medical attention if they, or a pet, showed signs of illness if they have ingested water during the warning period.
