切萨皮克含水层储存和恢复（ASR）可行性初步评估涉及以下问题:水供应和需求、水文地质、水质、适用性、环境问题、许可和必要设施。初步评估表明，拟建项目现场符合ASR的三个标准:1）供水和/或需水量的季节变化。通常，当最大年日需求与平均年日需求之比等于或超过1.3时，满足该标准。2） 合理规模的供水设施容量。由于规模经济和开发ASR井的初始成本，这可能是一种低于1 mgd有效回收能力的不合适技术。3） 考虑地质、水文、数量、质量、工程和物流因素的合适储存区。

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.
