We have a 0.6 acre community garden/ urban farm in Detroit and looking to grow it. We have a building we use to catch rainwater, but someone recently asked us if we had tested the water for chemicals from the roof. Does anyone know where I could send a sample? Thank You!

Contact your county Health Dept. to see if they can test the water for you. There will probably be a charge. If they don't do testing other than well water, they may be able to give you a list of reputable labs that can assist you.
