MN Daily: Dangerous algae blooms indication of water healthPosted Jul 27, 2016
Almost every year, reports come in of dogs dying after drinking from algae-infested waters, and people are cautioned not to swim in algae-filled lakes as it can sicken them.
While dangerous algae blooms are spurred by a complex array of ingredients — including wind speed, temperature and rainfall amounts — one thing that is well documented is that humans are allowing excess nutrients to flow into waterways.
Fertilizers spread on farm fields or lawns flow through farm drainage tiles or off the landscape. Grass mowed into streets or onto sidewalks can wash down storm drains and add more nutrients, and faulty septic systems can further fuel the problem.
