“…Their findings show that bicarbonate accounted for 20% to 80% of the total anions, chloride, and sulfate each accounted for 10% to 60%. In addition, sodium and potassium accounted for 40% to 100% of the cations [25]. The Ca 2+ , Mg 2+ , 2 4 SO − , and 3 HCO − may be derived mainly from weathering of carbonate rocks.…”

“…Fur-thermore, the upper aquifer is composed of alluvial, playa, eolian, and fan deposits of Pleistocene to Holocene age and the middle and lower aquifers consist of continental deposits of moderately consolidated gravel, sand, and boulders of Pleistocene age [16]. According to [25] the BV Groundwater aquifer is considered mostly as calcium-sodium-bicarbonate or sodium-mixed anion type waters. Their findings show that bicarbonate accounted for 20% to 80% of the total anions, chloride, and sulfate each accounted for 10% to 60%.…”

“…The quality of groundwater in the primary aquifer system may be different from that in the shallower or deeper water-bearing zones; shallow groundwater may be more vulnerable to surficial contamination [25]. In terms of nitrate, the results of our study and the synthesis of GAMA data for nitrate from 1980 to 2000 from similar wells throughout the BV groundwater basin as long-term data screening have demonstrated that the higher nitrate concentration in the water of shallow wells occurs in dry years (and dry months, and the lower nitrate concentration in wet years (and wet months September through February).…”

“…Construction and use of riverside groundwater well fields is advantageous for several reasons including the good recharge conditions and excellent opportunities for centralized exploitation and management compared to surface water [1,2]. With the treatment of water as it passes through the unsaturated zone, the quality of riverside groundwater is generally better and more stable than that of surface water.…”

This study aims to derive the optimal solution for well locations based on the allowable withdrawal. To demonstrate the proposed technique, a numerical model of a typical well field at the Qinbei Power Plant was constructed and 20 possible drawdown scenarios were simulated for each of three different arrangements of pumping wells. The concept of the Unit Increased Drawdown Value (UIDV) was used as a basis to select the location of pumping wells, where the UIDV is defined as the increase in drawdown associated with the addition of a unit of extraction. Results showed that for modeled well fields with the same number of wells and rates of exploitation, drawdown will reach the maximum and minimum when the well field is located in the recharge zone and discharge zone, respectively, because of the specific relationships between groundwater and surface water. This paper considered a pumping program with maximum exploitation and minimum costs corresponding to allowable withdrawals of 2.44 m 3 /s and 1.07 m 3 /s, respectively, and the relationship between groundwater and surface water was elucidated. The study results provide a theoretical basis for the layout of wells. The solution takes economic factors into consideration and describes the best solution for well locations to meet drawdown limitations during pumping applications.
