We often receive inquiries about vegetable gardening on real or suspected contaminated areas (neighborhoods that were once landfills or were filled in with waste, former agricultural land, etc). Last fall we produced and distributed a fact sheet, “Growing and Eating Fruits and Vegetables Safely” to assist the public in growing gardens safely.
We recently revised the fact sheet to include guidance regarding gardening over septic tanks. Attached is the newly revised version. The fact sheet provides questions and answers about gardening and real or potentially contaminated soils.
