A) Rain washes the Hydrocarbons down the Storm Drain and it ends up in our Rivers, Lakes and Oceans. B) Some may put dish detergent on the spill, which temporarily encapsulates some of the Hydrocarbons, and it is carried, by the detergent and water down the Storm Drain. The detergent bio-degrades and the Hydrocarbons end up in our Rivers, Lakes and Oceans. C) Others may put kitty litter on the spill and some of the Hydrocarbons are absorbed. Kitty litter is then washed down a Storm Drain, biodegrades and the Hydrocarbons end up in our Rivers, Lakes and Oceans. If the kitty litter is swept up, it should be disposed of in a Landfill specifically suited for hazrdous materials, otherwise it goes to a regular Landfill and pollutes our soil and may be carried by rain, ground water to our Rivers, Lakes and Oceans. D) If a Spill Kit is used correctly, the contents, again, should end up in a Landfill suited for the contaminates. E) Call us: We will clean the contaminated surface and recover the effluent and clarify the wastewater for safe discharge into the environment.
