TPH Risk-Based Strategies
This presentation discusses recent developments in Total Petroleum Hydrocarbons (TPH) risk-based strategies. The unique fate and transport properties of TPH- specifically in biodegradation and metabolite production—affect how risk should be assessed at the site. Understanding TPH analytical data, CSM and regulatory framework is critical in determining realistic risk management options on the road to site closure.
