In Arizona, the 'Prior Appropriation Doctrine' for water rights means that:

AAll water users with adjacent land rights share equally in available surface water during shortages, with no priority given to the date the right was first established

BWater rights are allocated based on priority date—'first in time, first in right'—so senior water rights holders have priority over junior holders during shortagesCorrect

CThe state holds all surface water rights in trust for the public and allocates them annually through a competitive bidding process administered by ADWR

DGroundwater is governed by the same prior appropriation rules as surface water in Arizona, with priority dates established at the time the well was first drilled

Why Water rights are allocated based on priority date—'first in time, first in right'—so senior water rights holders have priority over junior holders during shortages Is Correct

Answer B: Water rights are allocated based on priority date—'first in time, first in right'—so senior water rights holders have priority over junior holders during shortages

Arizona follows the prior appropriation doctrine for surface water: the first person to put water to beneficial use has priority. During shortages, junior (newer) water rights are curtailed before senior rights.

Environmental questions test knowledge of hazards like asbestos, lead-based paint, radon, and mold. Know the disclosure requirements and when a professional inspection is required. CERCLA liability is strict, joint, and several.
