1 Hazco Environmental utilized OSE II for an undergorubd Storage tank clean up and removal
2 the soil from around and under the tanks was set on the side of the excavated holes to have OSE II applied exsitu
3 Hazco Environmental Utilized an old fire department truck to mix OSE II in its tank for application
4 Hazco Environmental employee applying OSE II to dirt excavated from the storge tank hole
5 Hazco environmnetal thoroughly applying OSE II to dirt pile
6 Hazco Environmkental applying OSE II to a second pile of contaminated dirt
7 Continued application of OSE II and water to excavated contaminated dirt
8 the area of the excavated hole was determined in order to apply the correct amount of OSE II
9 Hazco environmental then applied OSE II to the hole
10 Hazco environmental move the application nozzle back and forth to saturate the surface area of the excavated hole
11 OSE II was applied until the entire hole had been saturated
12 Hazco Environmental saturating the pit walls with OSE II and water
13 Hazco Environmental finishing off the application of OSE II and water
14 The day after applying OSE II a heavy rain filled the excavarted pit
15 OSE II was then applied to the water in the pit to remove a slight sheen
16 The rain water actually helped OSE II remove all the contaminants from the pit soil
17 Hazco Environmental then extracted samples 3 days after the rain and had the soil and water tested for hydrocarbons and especially benzene
18 Hazco Environmental received the lab results which showed the hydrocarbon and benzene levels to be below the State of Texas required levels
19 Hazco Environmnental drained the pits since the water was deemed free of contaminants, and the pit was filled in and the property was then able to
