Assessing Risk / Establishing Cleanup Levels
CLARC is not currently a searchable database. CLARC is a collection of technical information to assist in setting cleanup standards under the Model Toxics Control Act (MTCA). It includes a series of spreadsheets of chemical-specific information, pre-calculated cleanup levels, technical documentation and related guidance documents.
The following documents provide guidance and calculation tools for demonstrating natural attenuation of groundwater is occurring and enable prediction of when groundwater cleanup levels will be met.
