VI. RECOMMENDED APPLICATION PROCEDURE
Recommended application procedures depending on concentration of contaminants, water salinity levels, water temperature, and the type and age of the contaminant. There are two means of application: power spraying or direct application. a. Application via power spraying: Use of a power washer to spray the contaminated surface. The action may be improved by warming the product during use. b. Application via direct application: Remove contaminated soil, sand, etc. into a container. Irrigate the affected ground with the product and let it soak in. Agitate the mixture of water/product/ground and add additional water to float the contaminant off of the surface. A layer of product-contaminant will form which may be physically separated from the soil. The oil in this layer may be separated by dehydration or pumping to prepare the contaminant for disposal or reclamation. The clean soil or sand may be returned to its original environment. The residue should be removed and disposed of as required by local, state, or federal regulations. The on-site coordinator can determine the best way to recover the residue based on the spill type, surface, and environment of the area. Concentrations: The concentration of the BIOGRASS EXTRA® product to be used depends on the density of the contaminant. Normally the product is used in a one-to-one proportion with the contaminant.
