During an on-site evaluation, which areas are required to be checked for leachate?

The requirement to check both manure storage and silage/feed storage areas for leachate during an on-site evaluation is anchored in the need to prevent pollution and manage nutrient runoff effectively. Manure storage areas can produce leachate due to precipitation or water interaction, which can carry nutrients and pathogens into groundwater or surface water. Similarly, silage and feed storage areas can also generate leachate, particularly from the fermentation of the silage itself, which can be nutrient-rich and pose similar environmental risks.

By monitoring both types of storage areas, producers can identify potential sources of contamination early on, implement remedial measures, and ensure compliance with nutrient management regulations. This holistic approach is essential in maintaining environmental stewardship and protecting water quality, particularly in agricultural settings where nutrient runoff can have significant ecological impacts.
