22 M.R.S. §2641: Source of public water supply defined

As used in this subchapter, unless the context otherwise indicates, "public water source" means any natural or human-made impoundment, pond or lake or ground water aquifer whose waters are transported or delivered by a public water system, as defined in section 2601, subsection 8. Where the intake of a public water supply is on the outlet of any impoundment, pond or lake, the source of the public water supply is considered to be the impoundment, pond or lake itself.
