Soil Contaminants and Soil Testing
To learn about how to test soil, see Cornell Waste Management Institute Guide to Soil Testing and Interpreting Results.
The NCAT Alternative Soil Testing Lab Locator is one tool to help locate a soil testing laboratory.
Urban farmers and gardeners can use some simple best practices to help ensure a safe growing environment, such as mulching pathways and washing hands after working in the garden. See What Gardeners Can Do: 10 Best Practices for Healthy Gardening (Spanish version - Lo que los jardineros podemos hacer: 10 Consejos para practicar la jardinería demanera saludable).
Your County’s UC Cooperative Extension office and County Environmental Health Department may have more information regarding soil testing. Additional helpful resources can be found at:
