(SDW-1b) Number of tribal community water systems (CWSs) that have undergone a sanitary survey within the past three years (five years for outstanding performers) as required under the Interim Enhanced and Long-Term 1 Surface Water Treatment Rules.

Type of Measure: Target measure; Annually reported

Measure Contact: Ronald Bergman, EPA Office of Ground Water and Drinking Water
bergman.ronald@epa.gov | (202) 564-3823

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 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) requires states to conduct sanitary surveys once every three years only for community systems that are surface water or ground water under direct influence of surface water systems, not for all community systems. Ground water systems will not be included under the requirement to conduct sanitary surveys until the Ground Water Rule (GWR) is promulgated. For community systems determined by the state to have outstanding performance based on prior sanitary surveys, subsequent sanitary surveys may be conducted no less than every five years (per 142.16(b)(3)(ii)).

Units: Sanitary surveys

Measure Contact: Charles Job, EPA Office of Ground Water and Drinking Water
job.charles@epa.gov| (202) 564-3941

Measure Definition

Terms and phrases:

  • A violation is a failure to meet any state or federal drinking water regulation.
  • A public water system (PWS) is any water system which provides water to at least 25 people for at least 60 days annually. There are more than 170,000 PWSs providing water from wells, rivers and other sources to about 250 million Americans. The others drink water from private wells. There are differing standards for PWSs of different sizes and types.
  • SDWIS-FED is the Safe Drinking Water Information System-Federal.
  • A maximum contaminant level (MCL) is the highest level of a contaminant that EPA allows in drinking water. MCLs ensure that drinking water does not pose either a short-term or long-term health risk. EPA sets MCLs at levels that are economically and technologically feasible.
  • A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.

Methodology for computation of results: This measure is calculated each year using data gathered during data verification audits of state programs. The EPA Office of Ground Water and Drinking Water (Headquarters) will calculate this measure and provide the results to EPA Regions.

Terms and phrases:

  • A community water system (CWS) is a public water system that supplies water to the same population year-round. 
  • SDWIS-FED is the Safe Drinking Water Information System-Federal.

Methodology for computation of results: The EPA Office of Ground Water and Drinking Water (Headquarters) calculates this measure every three years, to match the reporting cycle stipulated in the rule, using data reported in SDWIS-FED.

Each community water system (CWS) that was active at that time, served at least 3,300 people as of April 2005, and which was first reported to SDWIS-FED prior to CY 2004, should have reported at least one PB90 sample in this period. Completeness in the CY 2005-2007 period will be calculated in April 2008. Each CWS that was active at that time, served at least 3,300 people at that time, and which was first reported to SDWIS-FED prior to CY 2007, should have reported at least one PB90 sample in this period.

  • 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.’

Units: Cumulative dollar loans’ divided by ‘cumulative fund dollars available’

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. Line 183 in DWNIMS reports the number of projects completed each year while line 184 reports the cumulative number of projects completed since program inception. For all practical purposes, projects completed means projects initiating operations.

Measure Language:

(SDW-7a): Percent of deep injection wells that are used to inject industrial, municipal, or hazardous waste (Class I) that lose mechanical integrity and are returned to compliance within 180 days, thereby reducing the potential to endanger underground sources of drinking water.

(SDW-7b): Percent of deep injection wells that are used to enhance oil recovery or that are used for the disposal or storage of other oil production related activities (Class II), that lose mechanical integrity and are returned to compliance within 180 days, thereby reducing the potential to endanger underground sources of drinking water.

(SDW-7c): Percent of deep injection wells that are used for salt solution mining (Class III) that lose mechanical integrity and are returned to compliance within 180 days, thereby reducing the potential to endanger underground sources of drinking water.

Type of Measure: Target measures; Annually reported (all)

Measure Contact: Bob Smith, EPA Office of Ground Water and Drinking Water
smith.robert-eu@epa.gov | (202) 564-3895

Measure Definition

Terms and phrases:

  • 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.
  • Wells that lose mechanical integrity signifies that the well does not meet the definition of a well that has maintained mechanical integrity. A well has maintained mechanical when “(1) there is no significant lead in the casing, tubing or packer, and (2) there is no significant fluid movement into an Underground Source of Drinking Water through vertical channels adjacent to the injection well bore. (Defined in EPA Office of Ground Water and Drinking Water (OGWDW) July 2005 program measures memorandum.) When a well is returned to compliance it means that it was a well 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: Reporting forms, known as the 7520 forms (for their Office of Management and Budget number), are how EPA and primacy states collect and report the information they need to determine whether injection wells are operating properly and protecting public health. See http://www.epa.gov/ogwdw/uic/reportingforms.html for more information.
