Chlorinated Solvents

Chlorinated solvents and many of their transformation products are colorless liquids at room temperature They are heavier than water with densities greater than 1 gram per cubic centimeter (g/cm 3) which means they can penetrate deeply into an aquifer They are relatively volatile compounds with relatively high Henry's Law constants(K H) a measure of the strength of partitioning from water
