Some chemical solvents containing toxic chemicals including halogenated hydrocarbons and aromatic hydrocarbons are sold as sewerage system cleaners and degreasers. These chemicals are toxic, generally nonbiodegradable, and are a significant and unnecessary source of water pollution and groundwater contamination. When used to unblock or deodorize sewerage systems, they are introduced into the groundwater where they have adverse effects on the environment and health of the citizens of this state. It is the policy of this state to eliminate the introduction of these chemicals into the groundwaters of this state.
