摘要
利用Española盆地南部地下水的化学和同位素数据来完善地下水流动的概念模型,并评价水源和含水层分区。数据包括离子和微量元素化学,氧-18和氘,溪流,泉水和井的温度和电导率,包括国家工程多级压力表。碳酸氢钙水在盆地中占主导地位,但缺钙、富钠的水出现在有限的区域。在Buckman井田、Las Dos和Jacona断裂系统,以及Tesuque组深度超过1000英尺的地方,富钠水与更新世(?)稳定同位素特征有关。圣达菲西部毗邻Cerros del里约热内卢火山场和盆地的向斜轴,富含钠的高温水体与砷羽流相吻合。从Yates La Mesa #2勘探孔的测井资料显示,羽流也覆盖在深埋的火山流上,可能与埋藏的喷发中心有关。砷羽流的三维成像表明,超过10 μ g/L的浓度与井深和饱和含水层上部1700英尺的范围无关。其他结果表明,山地含水层与氯化物和硫酸盐丰富的水有关,并且相对较高的总溶解固体(TDS),钙和溴化物,从山前向西减少。圣达菲河和阿罗约洪多附近的地下水中TDS和主要离子的浓度最低。圣达菲城市地下浅层井中氯化物和氯化物:溴化物比例升高表明是人为来源。
Arsenic and sodium in ground water of the southern Espanola Basin, New Mexico-indicators of deep sources, and aquifer compartments
Chemistry and isotopic data from groundwater in the southern Española Basin are used to refine a conceptual model of groundwater flow and evaluate sources of water and aquifer compartmentalization. Data include ion and trace element chemistry, oxygen-18 and deuterium, temperature and conductivity from streams, springs, and wells, including State Engineer multi-level piezometers. Calcium bicarbonate water dominates the basin, but calcium-depleted, sodium-rich water occurs in limited areas. In the Buckman well field, Las Dos and Jacona fault systems, and at depths greater than 1000 ft in the Tesuque Formation, sodiumrich waters are associated with a Pleistocene (?) stable isotope signature. West of Santa Fe adjacent to the Cerros del Rio volcanic field and the synclinal axis of the basin, sodium-rich, high temperature waters coincide with an arsenic plume. Logs from the exploration hole Yates La Mesa #2 indicate the plume also overlies deeply buried volcanic flows possibly associated with a buried eruptive center. Three-dimensional imaging of the arsenic plume indicates that concentrations exceeding 10 µg/L are independent of well depth and range across the upper 1700 ft of saturated aquifer. Other results indicate mountain-block aquifers are associated with chloride-and sulfate-rich waters, and relatively elevated total dissolved solids (TDS), calcium, and bromide, which decrease west from the mountain front. Groundwater in the vicinity of the Santa Fe River and Arroyo Hondo, has the lowest concentrations of TDS and major ions. Elevated chloride and chloride:bromide ratios in shallow wells beneath urban Santa Fe suggest anthropogenic sources.
