Common use of Background and Purpose Clause in Contracts

Background and Purpose. The adsorption of chemicals to sediments and soils is an important process that affects a chemical’s dis- tribution in the environment. If a chemical is adsorbed to soil particles, it will remain on the soil surface and will not reach ground water. If a chem- ical is not adsorbed, it will xxxxx through the soil profile and may reach ground waters and then surface waters. Similarly, if a chemical adsorbed to sediment, it will accumulate in the bed and suspended load of aquatic systems. If a chemical is not adsorbed to sedi- ment, it will accumulate in the water column of aquatic systems. Informa- tion on the adsorption potential is needed under certain circumstances to assess the transport of chemicals in the environment. This section describes procedures that will enable sponsors to determine the adsorption isotherm of a chemical on sediments and soils.
