- Treat amendments with heat, chemicals,
or other means that reduce pathogens.
Always retain documentation of such
treatment.
• Record all soil amendment sources, application
dates, and methods of composting or treatment.
• Ensure that animal holding areas and manure
staging areas are far enough from wells to
prevent contamination.
• Avoid locating wells in flood zones or downhill
from other sources of contamination.
• Protect wells with grouting, sanitary caps, and
intact casings.
• Inspect wells and water sources before each
growing season to identify potential sources of
contamination.
• Test water used for drinking and hand washing
to make sure it meets drinking water standards
— is potable. Keep records of tests and results.
