What Your Soil Test Results Mean
The information below should be useful in determining how your test results compare with average background levels in the United States. If you print out the two comparison charts and insert your test results in the appropriate blank columns, you will see how your results compare with background levels as well as what the EPA has determined to be "safe" for humans as compared to wildlife (EccoSSLs).
We should be questioning the vast difference between what the EPA considers to be safe for humans as compared to animal life. Let's work together to educate each other, and to bring these discrepancies to the attention of our legislators.
