Petroleum Contaminated Soils in Highway Construction

Key Words:

There are between 0.8 to 1.2 million leaking underground storage tanks (USTs) mostly storing petroleum by-products
such as gasoline and fuel oil.  Leaking petroleum products from USTs contaminate soil and move to contaminate ground
water. In 1984 US Congress added Subtitle I to the Resource Conservation and Recovery Act to regulate leaking USTs.  
Now almost all the fifty states require removal and proper disposal of petroleum contaminated soils (PCSs) to prevent
further contamination of groundwater.  Excavated PCSs are disposed in Landfills, used for bioremediation and low
temperature description, and disposed in highway industry as construction materials.  The cost/benefit, engineering, and
environmental aspects of disposal of PCS in highway industry as a construction material is discussed in this paper.
