Abstract:
A geochemical evaluation of the ground water in Avra Valley, Arizona using major ions and the stable isotopes deuterium and oxygen-18 verifies that ground-water recharge from the surrounding mountains is negligible and that most ground water enters the valley as underflow from Altar Valley. Primarily granitic sediments result in soft waters with elevated pH in southern Avra Valley. Increasing sedimentary mineralization in northern reaches produces slightly harder waters. Elevated nitrate in the ground water results from intense local agriculture; uneven distribution of nitrate and corresponding ground-water mounding suggest leakage around irrigation well casings as the primary pathway for nitrates to the ground water.
