The purpose of this chapter is to authorize the use of moneys in the California Safe Drinking Water Fund for a grant program for public agencies owning or operating domestic water systems, as authorized pursuant to the provisions of the California Safe Drinking Water Bond Law of 1976. The Legislature hereby finds and declares that it is necessary to establish a grant program to aid public agencies in the construction of projects for domestic water systems, and that certain public agencies owning or operating domestic water systems will be otherwise unable to meet minimum safe drinking water standards established pursuant to Chapter 4 (commencing with Section 116275) of Part 12 of Division 104 of the Health and Safety Code.
