Description

We evaluate performance of a multi-well Aquifer and Storage Recovery (ASR) system in a freshwater aquifer in Jordan valley, Utah. Jordan Valley Water Conservancy District (JVWCD) developed this system to enable extracting more groundwater. JVWCD injects excess streamflow into the aquifer in the springtime to enable extracting a comparable amount of groundwater later. We define a recovery effectiveness (REN) index to quantify the portion of injected water that JVWCD can recover in subsequent months from the same well. We employ MODFLOW-MT3DMS simulation to estimate RENs of individual ASR wells. For storage duration of 1 year, wells located in steep gradient have low REN. However, if sufficient additional groundwater rights exist, most system wells have high REN. The high achievable REN proves the applicability of ASR for long-term storage in freshwater aquifers with moderate groundwater gradient.
