Phase II Environmental Site Assessment

Phase II Environmental Site Assessment (Phase II ESA) reports are sometimes required when a Recognized Environmental Condition (REC) is found during the Phase I Environmental Site Assessment process. They may initiate Investigations to collect additional information or fill data gaps and are needed to identify the potential for the existence of an environmental liability that […]


Phase I Environmental Site Assessment

An Environmental Site Assessment (ESA) is an investigation designed to determine whether any environmental issues have impaired the subject property. The ESA reveals the probability of hidden liabilities for the user(s) of the Phase I ESA. The ESA will satisfy the all appropriate inquiry set forth in 42 U.S.C. Section 9601 (35) (b) of the […]


A Comparison of In-Situ Chemical Delivery Methods

A series of three chemical oxidant injection events, utilizing three different techniques, was conducted at a petroleum impacted site. The assessment between the three methods define the higher performance achieved utilizing Kinetically Adjustable Pore Space Dilation Injection Delivery System (KAPSDIDS). By comparison, oxidant solution was delivered at least 3 times further from the injection point […]


Case Study – Pilot Test of ISCO applied with KAPSDIDS

The overall study objective was to evaluate chemical oxidant distribution and contact utilizing the Kinetically Adjustable Pore Space Dilation Injection Delivery System (KAPSDIDS), designed by Badger Injection Solutions, LLC. The following summarizes the evidence of enhanced subsurface chemical distribution in the pilot test area. R-001500-02A-Pilot
