Abstract
This invention relates to the use of activated charcoal granule compositions which, when dry spread and "watered-in" to a site, reduces undesirable biological activity of deleterious organic compounds. When wet, these granules disperse very rapidly with a large dispersion area to original granule diameter ratio. The granules have high loadings of charcoal, i.e., from about 60 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent dispersing; rewetting; and binding properties.
