The case studies presented in the document link below highlight the use of Total Petroleum Hydrocarbon (TPH) data for soil, soil vapor, groundwater, surface water and ambient air associated with the risk-based investigation, remediation and long-term management of petroleum releases. The case studies in large reflect current, HIDOH guidance and were prepared with input from multiple, outside state and federal regulators as well as private consultants and experts associated with the petroleum industry. The primary authors, Roger Brewer with the HIDOH and Manivannan (Mani) Nagaiah with Langan Engineering & Environmental Services, Inc., in Florida, are also active members of the Interstate Technology & Regulatory Council (ITRC) (TPH Risk work group) and acknowledge important contributions to the document from many of the ITRC team members. The HDOH Case Studies will be referenced in the ITRC TPH Risk document for examples of the site-specific use of TPH data in a variety of petroleum-release scenarios (anticipated publication early 2019).
Comments are invited for the draft, January 2018 document posted below and should be provided to Roger Brewer no later than March 15, 2018 (email@example.com). A final version of the document will be posted in March.
