023 "Public drinking water supply" shall mean that ground water used in a public water supply system.
024 "Public water supply system" shall mean a water supply system designed to provide the public water for human consumption if such system has at least fifteen service connections or regularly serves at least twenty-five individuals. Public water supply system includes, but is not limited to,
a) any collection, treatment, storage, or distribution facilities under control of the operator of such system and used primarily in connection with such system; and
b) any collection or pretreatment storage facilities not under such control which are used primarily in connection with such system. For purposes of this subdivision, a connection to a system that delivers water by a constructed conveyance other than a pipe shall not be considered a connection if
i) the water is used exclusively for purposes other than residential uses, such as drinking, bathing, cooking, and other similar uses,
ii) the Department of Health and Human Services Regulation and Licensure determines that alternative water to achieve the equivalent level of public health protection provided by the Nebraska Safe Drinking Water Act and rules and regulations under the act is provided for residential or similar uses for drinking and cooking, or
iii) the Department of Health and Human Services Regulation and Licensure determines that the water provided for residential or similar uses for drinking, cooking, and bathing is centrally treated or treated at the point of protection provided by the Nebraska Safe Drinking Water Act and the rules and regulations.
An irrigation district in existence prior to May 18, 1994, that provides primarily agricultural service through a piped water system with only incidental residential or similar use shall not be considered to be a public water system if the system or the residential or similar users of the system comply with subdivision (ii) or (iii) of this subdivision. A water supplier that would be a public water system only as a result of the amendments made by the 1996 amendments to the federal Safe Drinking Water Act shall not be considered a public water system until August 7, 1998.
025 “Rem” shall mean the unit of dose equivalent from ionizing radiation to the total body or any internal organ or organ system. A “millirem” (mrem) is 1/1000 of a rem.
026 "Remedial action" shall mean any immediate or long term response to a pollution occurrence including cleanup, restoration, mitigative actions, and any other action approved or required by the Department.
