The Interstate Technology Regulatory Council (ITRC) is a state-led coalition of regulators, industry experts, stakeholders, academia, and federal partners that work to achieve regulatory acceptance of innovative environmental technologies and expedite quality decision making, while protecting human health and the environment. 


Over the past two years, Mr. Matt Flinchum, Director of Assessment and Remediation at Duncklee & Dunham, has collaborated with other dedicated environmental professionals on the ITRC’s Advanced Site Characterization Tools (ASCT) Team to develop this newly released web-based guidance.  This comprehensive and user-friendly guidance was created to assist stakeholders with the proper selection and application of ASCTs, as well as the interpretation of the data collected to improve conceptual site models and better develop site-specific remedial strategies for contaminated sites.  The guidance divides the ASCTs into four categories: Direct Sensing, Borehole Geophysical, Surface Geophysical, and Remote Sensing.  ASCTs provide the means to generate rapid high-density site characterization data and display these data and other site conditions in three dimensions.  When compared to traditional site-investigation methods, ASCTs allow one to gain a better understanding of contaminant concentration, mass, and distribution, as well as site stratigraphy, geology and hydrogeology. 


Duncklee & Dunham is experienced in the use and application of many ASCTs and is a proponent of their use when appropriate to meet project goals.  Duncklee & Dunham has also been a member of the ITRC’s Industry Affiliate Program for many years and has participated in several uniform national guidance documents over the years.  A link to the new guidance for Implementing Advanced Site Characterization Tools can be found here.
