The TGM identifies technical considerations for performing hydrogeologic investigations and ground water monitoring at potential or known ground water pollution sources. The purpose of the guidance is to enhance consistency within the Agency and inform the regulated community of the Agency’s technical recommendations and the basis for them. In Ohio, the authority over pollution sources is shared among various Ohio EPA divisions, including the Emergency and Remedial Response (DERR), Hazardous Waste Management (DHWM), Solid and Infectious Waste (DSIWM), and Surface Water (DSW), as well as other state and local agencies.
This technical guidance is a series of PDF documents and was originally published in 1995. These documents will be periodically updated and the most current versions can be downloaded from the list below. The current version will contain a summary of major changes. DDAGW will archive older documents and maintain their availability (See Archive in the below list).
