Workshop TM1.

Understanding TPH for the management of contaminated sites

Thursday, 12 September, 2019

Presenters: Dr. Atul Salhotra

Summary

Total Petroleum hydrocarbons is a mixture of hundreds of chemicals. The behavior of these chemicals in the environment (fate and transport properties) and the toxicity of several of these chemicals is not known. This presents a significant challenge to incorporate the TPH concentrations in the evaluation of contaminated sites such as crude productions sites, gas stations, refineries, landfills, and pipeline sites. Many approximate methods have been developed that include a combination of indicator chemicals and TPH fractions.
This course will discuss the various approaches used to estimate the risk from TPH and to incorporate it in the assessment of hydrocarbon impacted sites.

Who should attend?

The workshop will be useful for all stakeholders involved in the assessment and management of petroleum impacted sites. These include regulators, responsible parties, and service providers. No previous background in risk assessment is required. Geologists, engineers and environmental professions with a variety of educational backgrounds will benefit from this course.
