This St. Louis family lost their dog to toxic algae. Why aren’t more states testing their lakes?

The dog died after exhibiting textbook symptoms of toxic algae poisoning. Harvest Public Media reporter Dana Cronin explains why toxic algae is a growing concern, and why Missouri and Illinois don’t regularly test their lakes.
