Chlorinated solvents are a group of organic compounds that contain chlorine and are commonly used in various industrial processes, such as metal degreasing, dry cleaning, and electronics manufacturing. Some examples of chlorinated solvents include trichloroethylene (TCE), perchloroethylene (PCE), and carbon tetrachloride (CT). Chlorinated solvents are highly effective as solvents due to their chemical properties, but they are also highly toxic and persistent in the environment. They can easily contaminate soil and groundwater, and exposure to these compounds can have serious health effects, including damage to the liver, kidneys, and nervous system, as well as an increased risk of certain cancers. Chlorinated solvents can enter the environment through spills, leaks, or improper disposal of waste. Once released, they can migrate relatively long distances through soil and groundwater, contaminating water sources and posing a risk to human health and the environment. Remediation of chlorinated solvent contamination typically involves the use of specialized technologies, such as in-situ chemical oxidation, enhanced reductive dechlorination, or soil vapor extraction.
