ECOL, American Ecology has defined itself well over the years and found a niche in waste management. They provide disposal services for low-level radioactive and hazardous waste. This business requires following of tough government regulations, permissions, and licenses which keep out competition. The company is continuously improving its transportation infrastructure such as increasing railcar fleets and rail facilities. They will be able to move larger amounts of material and reach more businesses....this will improve both the top & bottom line. I don't expect this stock to make leaps and bounds anytime soon, but it pays a nice 3% dividend for the wait.
