address the principal threat at the site by preventing current or future exposure to the contaminated soil through treatment and/or containment‚ and reducing or controlling the potential migration of contaminants from the soil to ground water. Remedy Selection A proposed plan for the site was issued in August 1990‚ presenting the preferred alternative of chemical dechlorination of the contaminated soil. The EPA Regional Administrator for Region 6 signed a Record of Decision (ROD) on September 27‚ 1990

Some factors that affect biodiversity of species are what are around the biomes‚ the unnatural species living there‚ extreme climate changes (in general)‚ pollution‚ unusual weather changes(drought

As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although it is sometimes said that the entire planet is an ecosystem). Energy‚ water‚ nitrogen and soil minerals are other essential abiotic components

the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them) because they consist
