Drinking Water Information for Arkansans

SOURCE WATER PROTECTION PROGRAM


Appendix A -- Glossary and Acronyms

Assessment Area: A delineated area around the intake or well head of a public water system that establishes the general boundary for Vulnerability Assessment. The area will not extend past the State boundaries and will be determined by a fixed radius, and / or topographical or hydogeological method.

Ground Water: Naturally occurring water occupying the zone of saturation in the ground below the surface of the earth.

GWUDI: Ground Water Under the Direct Influence of Surface Water. Water beneath the surface of the ground with significant occurrences of insects or other macro-organisms, algae, or large diameter pathogens such as Giardia-lamblia, or significant and relatively rapid shifts in water characteristics such as turbidity, temperature, conductivity, or pH which closely correlate to climatological or surface water conditions.

High Water Level: The line on the shore of an impoundment that is reached at the normal spillway elevation.

Off Stream Storage: A natural or man made basin used for the purpose of storing raw water for use by a public water system as a supplement to the primary source of raw water.

Median Stream Flow: The rate of flow for which there are an equal number of greater and lesser occurrences during a specified period.

Permeability Weight: A relative rating of the capacity of the aquifer material to transmit water or contaminates.

Phase I Assessment Area: The area delineated for the purpose of the Source Water Assessment Program. This is the minimum area that will be considered in the vulnerability assessment.

Phase II Assessment Area: Upon completion of vulnerability assessments for all water sources, and if resources allow, an expanded area for each source will be delineated and evaluated. The Phase II Assessment Areas will be based on either State prioritization of systems, new data acquired, or in the process of providing technical assistance in the development of a Protection Plan.

PSOC: Potential Sources of Contamination. A contaminant that has the potential to adversely affect the quality of a drinking water supply.

Significant PSOC: A contaminant that has the potential to adversely affect the quality of a drinking water supply at such a magnitude as to exceed an MCL or health advisory level.

Surface Water: Water that flows over or rests upon the surface of the earth. The term surface water includes rivers, lakes, impoundments, reservoirs, and springs in addition to other man-made and naturally occurring bodies of water on the surface of the earth.

Time of Travel: The time necessary for contaminants to travel a given distance from the source of contamination to the intake or well.
