Drinking water for about 500,000 people in Ohio was deemed toxic last weekend, but water company officials here say there are precautions in place to protect against a similar situation. The problem in Toledo was due to an algae bloom, which can come from fertilizer, livestock pens, or septic tanks.
Karen Cotton, Illinois American Water spokesman, says they consistently work to control algae blooms in source waters for their surface water treatment plants.

People in Toledo had to go without water for two days because toxins ended up in Lake Erie. The algae that produced toxins rendering Toledo's water unusable for several days bloomed in shallower water with more sunlight.
