Groundwater protection is an important issue in water resources management that can be achieved using a more efficient and economic methodology;
allowing water use and economic development to coexist. Current protection strategies commonly lead to inefficient use of water resources and protracted disputes. This article proposes adopting a groundwater protection strategy based on spatial and temporal zoning of aquifers and aquifer systems;
similar to the strategy for land use management. In some groundwater basins a common-sense spatial scheme can be developed with buffers separating potentially conflicting water and land uses. More intense uses would be located down-gradient or cross-gradient from sensitive uses (e.g;
potable-supply wells). Where groundwater data are abundant;
modeling would be used to establish buffer dimensions;
allowing more intense uses to be located in closer proximity. Monitoring wells would be located in the buffers to ensure compliance with water quality standards and criteria. 2014 © American Water Works Association;
