Major element concentrations of river water, groundwater, irrigation canals and drains, and city waste effluents from the Middle Rio Grande Watershed

This dataset provides major element concentrations (mg/L) for Ca, Na, Mg, K, Si, Cl, SO4, and NO3 for water samples collected from the Middle Rio Grande Watershed. Major element concentrations were measured by ICP-OES and Cl, SO4, and NO3 were measured by ion chromatography. The samples include river water, groundwater, irrigation canals and drains, and city waste effluents collected between 2014 and 2016. Funding source: NSF EAR-1349091.

本数据集提供了从中里奥格兰德流域（Middle Rio Grande Watershed）采集的水样中钙（Ca）、钠（Na）、镁（Mg）、钾（K）、硅（Si）、氯（Cl）、硫酸根（SO4）以及硝酸根（NO3）的常量元素浓度（单位：mg/L）。其中常量元素浓度采用电感耦合等离子体发射光谱法（ICP-OES）测定，氯、硫酸根及硝酸根则采用离子色谱法完成检测。本次采集的水样涵盖河水、地下水、灌溉渠与排水沟渠以及城市污水尾水，采样时段为2014年至2016年。资助来源：美国国家科学基金会（NSF）EAR-1349091。
