lab to test for herbicide and pesticide residue
Is there a Maryland or DC-based lab you could recommend to test our soil for herbicide and pesticide residue?
Montgomery County Maryland
Herbicde and pesticide testing is very expensive, and you must tell them what specific chemical you are testing for. This makes testing difficult.
You may want to contact the National Pesticide Information Center (NPIC): 1-800-858-7378.
We do not have a recommendation for pesticide or herbicide testing. Our soil testing information is in the icon on the right side of our home page. It includes a list of soil testing labs in our region.
