The preliminary assessment of aquifer storage and recovery (ASR) feasibility for Chesapeake addressed the following issues: water supply and demand, hydrogeology, water quality, suitability, environmental issues, permitting and necessary facilities. The preliminary assessment indicated that the proposed project site met the three criteria for ASR which are: 1) Seasonal variation in water supply, water demand, or both. Typically when the ratio of maximum- annual-day to average-annual-day demand is equal to or exceeds 1.3, this criterion is met. 2) A reasonable scale of water facilities capacity. Because of economies of scale and the initial cost of developing ASR wells, it may be an inappropriate technology below 1 mgd useful recovery capacity. 3) A suitable storage zone, considering geologic, hydrologic, quantity, quality, engineering, and logistical factors.
