“…The Fraser aquifer is unconfined to semi-confined glacial outwash, which is the target aquifer for municipal, domestic, and agricultural use. The Puget aquifer underlies the Fraser, and is found at depths greater than 45 m [66]. Due to the prolific nature of the Fraser aquifer, the Puget aquifer is not heavily utilized as a groundwater source.…”

Developing aquifers as underground water supply reservoirs is an advantageous approach applicable to meeting water management objectives. Aquifer storage and recovery (ASR) is a direct injection and subsequent withdrawal technology that is used to increase water supply storage through injection wells. Due to site-specific hydrogeological quantification and evaluation to assess ASR suitability, limited methods have been developed to identify suitability on regional scales that are also applicable at local scales. This paper presents an ASR site scoring system developed to qualitatively assess regional and local suitability of ASR using 9 scored metrics to determine total percent of ASR suitability, partitioned into hydrogeologic properties, operational considerations, and regulatory influences. The development and application of a qualitative water well suitability method was used to assess the potential groundwater response to injection, estimate suitability based on predesignated injection rates, and provide cumulative approximation of statewide and local storage prospects. The two methods allowed for rapid assessment of ASR suitability and its applicability to regional and local water management objectives at over 280 locations within 62 watersheds in Washington, USA. It was determined that over 50% of locations evaluated are suitable for ASR and statewide injection potential equaled 6400 million liters per day. The results also indicate current limitations and/or potential benefits of developing ASR systems at the local level with the intent of assisting local water managers in strategic water supply planning.

“…Information on the ratio of horizontal to vertical hydraulic conductivity is limited. Some studies estimate an anisotropy ratio of approximately 10 in the coarse-grained aquifers, such as Qva (Morgan and Jones, 1996). Our initial-case simulation used isotropic conductivities, and we examined the effect of anisotropic conductivity in the upper aquifer in our sensitivity analyses.…”

“…To simulate the effect of ground-water seepage from the bluff, we used the MODFLOW-2000 drain package. This package is designed to simulate the effect of features similar to an agricultural drain (McDonald and Harbaugh, 1988) and is commonly used to simulate seepage faces in regional groundwater flow models (Sapik and others, 1988;Anderson and Woessner, 1992;Morgan and Jones, 1996;Fabritz and others, 1998;Vaccaro and others, 1998). Drain cells have the effect of removing water from the aquifer at a rate proportional to the difference between the head in the aquifer and the elevation of the drain.…”

“…On the basis of these values, large precipitation events in the Little Androscoggin River Basin are capable of infiltrating and the permeability of the till would not be a factor leading to overland flow and thus a loss of recharge to the aquifer. Morgan and Jones (1995) conducted a study of the effects of ground-water withdrawals on discharge to streams and springs in small basins typical of the Puget Sound Lowland in Washington State. In their study, reference is made to a written communication (1993) with J.J. Vaccaro (U.S. Geological Survey) in which permeameter measurements of hydraulic conductivity were made in till and showed a range from 0.0002 to…”

“…Vaccaro estimated that the average annual recharge in areas underlain by till and other finegrained deposits was 17.5 in. In the simulation used in Morgan and Jones (1995), a mean annual precipitation of 44 in/yr and a recharge rate of 18 in/yr were used in the areas where the less permeable till was exposed. This recharge rate is similar to the 18.3 in.…”

This report presents regression equations to estimate generalized annual and seasonal groundwater recharge rates in drainage basins in New Hampshire. The ultimate source of water for a groundwater withdrawal is aquifer recharge from a combination of precipitation on the aquifer, groundwater flow from upland basin areas, and infiltration from streambeds to the aquifer. An assessment of groundwater availability in a basin requires that recharge rates be estimated under 'normal' conditions and under assumed drought conditions. Recharge equations were developed by analyzing streamflow, basin characteristics, and precipitation at 55 unregulated May 31) groundwater recharge was 9.0 in., average summer (June 1-October 31) groundwater recharge was 4.0 in., and average fall (November 1-December 31) groundwater recharge was 3.6 in. Normalized groundwater recharge ranged annually from 12.3 to 31.8 in., for winter from 2.30 to 7.82 in., for spring from 5.16 to 13.7 in., for summer from 1.45 to 10.2 in., and for fall from 2.21 to 6.06 in. Description of Study Area New Hampshire encompasses an area of 8,973 mi 2 of which 309 mi 2 is water (New Hampshire State Data Center, 2001) (fig. 1). The State is in the Seaboard Lowland, New England Upland, and White Mountain sections of the New England Physiographic Province (Fenneman, 1938). The southeastern part of the State primarily is coastal plain, the central region primarily is lowland and foothills, and the northern part primarily is mountainous. The elevation and amount of topographic relief gradually increase from south to north. Precipitation ranges from an annual mean of about 35 in. in the Connecticut and Merrimack River valleys to about 90 in. on the summit of Mt. Washington (Hammond, 1989). Typically, statewide, the driest month is February. The wettest months are November and December in the area south of the White Mountains, and June, July, and August in the area north of the White Mountains (Hammond, 1989). Average runoff ranges from 18 in/yr in parts of the Connecticut River Valley and seacoast area to about 42 in/yr in the White Mountains. Streamflow varies both seasonally and geographically. High flows typically occur during
