At least 716,982 gallons (45 percent) of the petroleum chemicals spilled during the past decade have stayed in the ground after initial cleanup — contaminating soil, sometimes spreading into groundwater, a Denver Post analysis of COGCC data found. Thats about one gallon of toxic liquid every eight minutes penetrating soil. In addition, drillers churn up 135 to 500 tons of dirt with every new well, some of it soaked with hydrocarbons and laced with potentially toxic minerals and salts. And heavy trucks crush soil, suffocating the delicate subsurface ecosystems that traditionally made Colorados Front Range suitable for farming.
