Terms and phrases:

o    A community water system (CWS) is a public water system that supplies water to the same population year-round.

o    Source water is untreated water from streams, rivers, lakes or underground aquifers that is used to provide public drinking water, as well to supply private wells used for human consumption.

A system is considered to have source water protection in place if it meets the state specific definition of substantial implementation of a source water protection. The total number of community water systems and the total population served is taken from the Safe Drinking Water Information System-Federal (SDWIS-FED).

eisenberg.mindy@epa.gov | (202) 564-1290

Measure Definition

Terms and phrases: 

A community water system (CWS) is a public water system that supplies water to the same population year-round. 

A primacy agency is a state, territory or tribal government with primary enforcement authority for the Public Water System Supervision (PWSS) program. EPA is the primacy agency for Wyoming, the District of Columbia and in Indian country, except for the Navajo Nation.

A sanitary survey is an on-site review of the water sources, facilities, equipment, operation, and maintenance of a public water system for the purpose of evaluating the adequacy of the facilities for producing and distributing safe drinking water.

Methodology for computation of results: The Interim Enhanced Surface Water Treatment Rule (IESWTR) and the Ground Water Rule (GWR) require primacy agencies to conduct sanitary surveys once every three years for CWSs. For CWS determined by the primacy agency to have outstanding performance based on prior sanitary surveys, subsequent sanitary surveys may be conducted no less than every five years per sec. 142.16(b)(3)(ii) and sec. 142.16(o)(2)(iii). In addition, ground water systems approved by the primacy agency to provide 4-log treatment of viruses may have sanitary surveys conducted no less than every five years (per sec. 142.16(o)(2)(iii).

Units: Sanitary surveys

Universe: [SDW-01a: 49,283 Number of surface water CWSs for FY 2013]; [SDW-01b: 710 Number of tribal CWSs for FY 2013].

Measure Definition

Terms and phrases:

o    "The fund utilization rate shows how many dollars of assistance were provided for each dollar made available for projects. It measures all funds (federal and non-federal) signed into loans against all funds (federal and non-federal) made available for projects," as provided to Office of Management and Budget as a long-term output/efficiency goal Program Assessment Rating Tool (PART) response.

o    The Drinking Water State Revolving Fund (DWSRF) was established by the Safe Drinking Water Act, as amended in 1996, to make funds available to drinking water systems to finance infrastructure improvements.

Methodology for computation of results: Results are calculated by dividing cumulative assistance provided in the form of executed loans by cumulative funds available for projects. Assistance provided as a percent of Funds Available = 'Cumulative DWSRF Assistance provided' divided by 'Cumulative Funds Available.'

Measure Definition

Terms and phrases: The Drinking Water State Revolving Fund (DWSRF) was established by the Safe Drinking Water Act, as amended in 1996, to make funds available to drinking water systems to finance infrastructure improvements.

Methodology for computation of results: The Drinking Water National Information Management System (DWNIMS) is the information system of record for the Drinking Water State Revolving Loan Fund (DWSRF). All States report data for their DWSRF program to DWNIMS once each year. EPA develops a national summary of the DWSRF program from this data.

Terms and phrases:

o  An injection well is a device that places fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer. These fluids may be water, wastewater, brine (salt water), or water mixed with chemicals.

o  "Wells that have lost mechanical integrity" means that the well does not meet the definition of a well that has maintained mechanical integrity (Citations: 40 CFR 146.8; 40 CFR 144.28(f)(2)for authorized by rule (ABR) wells and 144.51(q) for permitted wells). Wells with MI failure would be considered to be in violation (with the exception of some 1425 programs). However, other MI violations, such as those related to late tests or record keeping, are not reported under this measure.

o  A "well returned to compliance" is a well that was in violation of Underground Injection Control (UIC) Program requirements, which has had the violation(s) corrected and has had the resolution of the violation(s) verified by the regulating authority.

Methodology for computation of results:  The number of wells that lose mechanical integrity and are returned to compliance are reported through the UIC Inventory and Measures Reporting System (IMRS) or through the UIC National Data Base

Units: Class I wells, Class II wells, Class III wells (salt solution mining ) as defined by the UIC Data Model Version 8.0 (edited 5/3/10).

Measure Definition

Terms and phrases:

  • A Class V motor vehicle waste disposal well (MVWDW) is a well used to inject fluids from motor vehicle repair or maintenance activities, such as an auto body repair shop, automotive repair shop, car dealership, specialty repair shop (e.g., transmission and muffler repair shop), or any other facility that does vehicle repair work.  These wells are classified as 5K as defined by the UIC Data Model Version 8.0 (edited 5/3/10).
  • EPA defines Large-Capacity Cesspools (LCC) as a well having the capacity to serve 20 persons or more per day and used solely for the subsurface emplacement of sanitary waste. These wells are classified as 5E as defined by the UIC Data Model Version 8.0 (edited 5/2/10).  The definition of "large-capacity" may vary from state to state as long as the definition is at least as stringent as the Federal definition. For example, some states define large-capacity cesspools based on the amount of waste or the volume capacity of the cesspool.

Methodology for computation of results: Number of MVWDW and LCC cumulatively permitted and/or closed as reported by primacy programs are reported through the UIC Inventory and Measures Reporting System (IMRS) or through the UIC National Data Base.
