n pi: a classification of injection wells under Safe Drinking Water Act that are related to hazardous, industrial nonhazardous, and municipal wastewater disposal below underground sources of drinking water.

n: (MIT) a test required prior to initial injection and once every five years thereafter (at a minimum) for certain types of injection wells under SDWA. These tests evaluate the operational integrity of the well so that underground sources of drinking water will not be endangered. EPA defines mechanical integrity as no significant leak in the casing, tubing, and packer and no significant fluid movement into a USDW through vertical channels adjacent to the injection well bore.

A regular pressure test on an injection well to assure the integrity of the isolation seal.

n: (SDWA) a congressional act that provides for the protection of underground sources of drinking water by regulating drinking water systems and injection wel1s.

n: (UIC) a program developed under SDWA to prevent injection well contamination of underground sources of drinking water. The UIC program divides injection wells into five classes (that range from common septic tanks to hazardous waste injection wells) and establishes specific requirements for construction, casing and cementing, plugging and abandonment, types of substances that can be injected, volume and pressures that can be injected, and mechanical integrity of the well.

n pI: (USDW) fresh water sources located under the surface that are suitable for use as drinking water supplies.

abbr: underground sources of drinking water.
