Re: Raid any idea how long to brake down in soil?
+1 on how much did you use? Is the well used to irrigate a garden or just the lawn? If just the lawn wouldn't worry about it, if garden I would call the number on the can or email mfg. website on can. Most water tests do not test for insecticide contamination. We recently had a fish pond contaminated by our tree care company, killed 9 of 10 fish. Huge PITA! to clean up. Small pond approx. 200 gal. Although the company stood up and paid to replace the fish, pond plants, and 6 hours of my time to clean, refill, clean again, and refill pond. If you have a County Extension Office they can direct you where to go to get the water tested for insecticide or contact any of the state universities that has an agricultural or turf grass program or even golf course mgt. program
