Treasure Coast governments spray more than 100,000 gallons of weed- and bug-killing poisons yearly at sites where the runoff can flow into waterways, but with minimal regulation, there main guideline is “follow the label instructions.”
Agencies and manufactures insist the chemicals sprayed in marshes, canals and ditches are safe, but no one tests for residue or effects of the Indian River Lagoon and other waters, despite a 1997 test that showed pesticide pollution in the St. Lucie River.
State officials say chemical companies work with the EPA to craft safe instructions. However, letting chemical companies set guidelines eliminates any meaningful oversight and leaves environmental health in industry’s hands.
