== Seeking info on groundwater contamination by pesticides == 

 Hi folks. I came here looking for information on groundwater contamination by pesticides. Most importantly, is it okay to spray the yard with commercial synthetic pesticides if we get our drinking water from a local well?  ('local' as in backyard, probably; i dont know the specifics but it's hooked up to the house's plumbing). I understand that a proper answer would need more specifics, perhaps. I checked the article on pesticides first (and asked this question at the talkpage there, too). I'll look over the related articles on drinking water and water wells. I believe other readers might like to know, too. -
