Groundwater Quality Data from Private Wells in Cache Valley

This dataset contains data on water samples collected from 9 private wells in Cache Valley. All of the samples were taken in May and June of 2015. The sampled wells were either under pressure and required only a release of lever/knob for water to flow, or had a pump that brought water to the surface. The depth of wells varied from 50 feet to 300+ feet. Sample locations were limited to the areas within or directly surrounding Logan, Mendon, Clarkston, and Smithfield. The water samples were analyzed for pH, DO, As (III), As (V), Fe (II), Sulfide, Anions, Total Metals, and Organic Carbon.

本数据集涵盖从卡什谷（Cache Valley）9口私人水井采集的水样数据。所有水样均采集于2015年5月至6月间。所涉采样水井分为两类：一类为承压水井，仅需扳动控制杆或旋钮即可出水；另一类则通过水泵将地下水提升至地表。水井深度介于50英尺至300英尺以上。采样点位仅限洛根（Logan）、门登（Mendon）、克拉克斯顿（Clarkston）及史密斯菲尔德（Smithfield）的辖区及其直接周边区域。本次检测对水样的分析指标包括pH值、溶解氧（Dissolved Oxygen，DO）、三价砷（As (III)）、五价砷（As (V)）、二价铁（Fe (II)）、硫化物、阴离子、总金属与有机碳。
