Surface water chemistry for a catchment impacted by gold mining in Porgera, Papua New Guinea

Water chemistry for samples collected in 2015 from streams (n = 6), rain barrels (n = 2), direct mine water discharge (n = 2), and springs (n = 2) in Porgera, Papua New Guinea. Field measurements of pH, alkalinity, conductivity, temperature, and dissolved oxygen are included for 52 additional water sources measured in 2015. Geochemical data are also included for water samples collected in January 2016 from a dam lake, two rain barrels, three springs, one creek downstream of the mine, as well as field measurements from eight additional sites. Water samples for geochemical analyses were analyzed for trace metals and major anions.

2015年在巴布亚新几内亚Porgera地区采集的水样水化学数据，来源包括溪流（n=6）、雨水桶（n=2）、矿井水直接排放口（n=2）和泉眼（n=2）。此外包含2015年对52个其他水源的现场测量数据，指标涵盖pH值、碱度、电导率、温度及溶解氧。同时还纳入2016年1月采集的水样地球化学数据，来源涉及一个坝体湖泊、两个雨水桶、三个泉眼、一条矿井下游溪流，以及另外8个站点的现场测量结果。用于地球化学分析的水样检测了痕量金属与主要阴离子。
