The oil is treated with hydrogen, which removes some of the sulfur by forming hydrogen sulfide gas. A method that identifies sources of oil and allows spills to be traced to their source. An accidental or intentional discharge of oil which reaches bodies of water. Deep clear lakes with few nutrients, little organic matter and a high dissolved-oxygen level. The capacity to induce cancer.
Opacity is an indicator of changes in performance of particulate control systems.
An uncovered site used for disposal of waste without environmental controls. A typical operable unit would be removal of drums and tanks from the surface of a site. Conditions specified in a RCRA permit that dictate how an incinerator must operate as it burns different waste types. A trial burn is used to identify operating conditions needed to meet speci- fied performance standards. Activities conducted after a Superfund site action is completed to ensure that the action is effective.
