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 at higher solution strength using KAPSDIDS. With an average injection rate of 28 gallons per minute, 500 gallons of treatment chemical was distributed to the target depth in less than 20 minutes.R-018000-05A-Method Comparison
