Calculation of Attenuation Rates

  • MES can calculate both attenuation and degradation rates

    • Attenuation rates can be calculated from historical site data

    • Degradation rates are developed from recent CSIA data

    • CSIA data can provide degradation rates for:

      • Petroleum compounds

      • Fuel Oxygenates

  • These rates can be used to decide remediation routes by:

    • Avoiding inefficient, long term pumping

    • Suggesting the most effective locations to concentrate remediation

  • MES can suggest Tier II analyses targeted to support proposed rates, providing confidence to regulators
