A characteristic of acidic and basic hazardous wastes.
The characteristic is defined by a waste's pH and its ability to corrode steel. A waste is corrosive if it has a pH less than or equal to 2.0 or greater than or equal to 12.5.

variable Any or attribute that can be measured.
variable charge The portion of a water bill that varies with water usage; also known as a commodity charge.

Monitor: To track a , such as dissolved oxygen, nitrate level, or fish population, over a period of time using uniform methods to evaluate change.
