In the subsequent Risk Management Decisions step, the result from step 2 is compared to the lower of Ih the solubility and ceiling values, and to the higher of the method detection limit (MDL) or background groundwater concentration for the contaminant of interest in order to arrive to the final criterion value. 2. CHEMICALIPHYSICAL AND ENVIRONMENTAL INFORMATION The relevant chemical/physical information is provided in Table environmental characteristics are shown in Table 2. 1. 3. STRUCTURE ACTIVITY RELATIONSHIP Structure Activity Relationships, or SAR, is a technique routinely used by US EPA to estimate aquatic toxicity of new industrial chemicals, pharmaceuticals, pesticides, and dyes being reviewed by the EPA in response to Pre-Manufacture Notices mandated by Section 5 of the Toxic Substances Control Act (TSCA) and in the absence of test data.

Central authorities will get involved in the event that the source of pollution cannot be identified or there is an immediate risk to the public.

Collectively, the guidance provided in these manuals supports a tiered framework for the assessment and remediation of contaminated sites as illustrated in Figure 1. The framework consists of three tiers, with the tiers progressing from generic numerical national guideline values to site-specific risk assessment for the derivation of site soil q~ality remediation objectives [4]. As is expected in a tiered system, the level of complexity increases with increasing tiers. Such tiered frameworks allow a suite of tools to be used that can be flexibly applied in reaching scientifically-defensible and economically feasible decisions.
