Arivaca Community Water Supply Drought Vulnerability Assessment
Water supplies in aquifer systems that are recharged by current precipitation are vulnerable to drought because recharge rates decrease during dry conditions. Preliminary studies on the groundwater source for Arivaca, AZ, suggest that recharge comes from contemporary monsoon rains. This project investigates the relationship between climate variability and groundwater to assess the vulnerability of this community’s principal water source to drought; it is also investigating options for sustainable water management.
