Description

This report provides a database of first-order biodegradation rates for select petroleum hydrocarbon compounds in groundwater. These rates have been obtained from the literature or by back calculation based on data from case histories. The rates have also been normalized to +5°C and +10°C using the rule-of-thumb Q10 = 2, which assumes that rates will approximately double for each 10°C increase in temperature, or be reduced by ½ for a temperature decrease of 10°C. Summary statistics have also been compiled for the data, and compared to rates published in Suarez and Rifai (1999), which does not include temperature details.

Description

This workshop was held in order to review the scientific basis for the Canada-Wide standard for petroleum hydrocarbons in soil (PHC CWS) and to review the prescriptive and performance based aspects of the analytical method. The workshop also reviewed the role of the Canadian Association for Environmental Analytical Laboratories in accreditation and allowed Alberta laboratories and consultants an opportunity to comment on early applications of the method.
