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
