QUESTION: H. Mulch: Mulch shall be made from recycled, kiln-dried wood products.

There is no known commercially available source of kiln-dried mulch, does SCVWD have a source? If not, what will alternative type of mulch will be acceptable?

ANSWER: The best option out there at present is biochar. This is organic material such as wood chips that has been heated hot enough to partially char. The heat kills microbes including the problem ones.

However, the problem with any "clean" material is that it may become contaminated by being placed on the ground of the storage facility (including on concrete or other pads) or by the truck that hauls bulk quantities to the placement site.
