It's been two years since drinking water in Toledo was contaminated by cyanobacteriain Lake Erie.
Four hundred thousand Toledo-area residents couldn't drink the water for a few days.

Taylor is a full-time volunteer with the Environmentally Concerned Citizens of South Central Michigan. She has been tracking the amount of manure produced by big factory farms in the Western Lake Erie Basin.
