Dissolved groundwater geochemistry time-series with methane over Marcellus Shale in NY

Eleven domestic water wells over the Marcellus Shale in New York were sampled monthly for 13 months. They were analyzed for dissolved hydrocarbons (methane, ethane, propane) and major ion concentrations (Ca, Mg, K, Na, NH4, SO4, Cl, F, Br, NO3). Biannual (Jun & Dec 2017) methane and water isotope measurements are included for wells with sufficient concentrations. The likely sources of salinity and probabilities for each well for each month are also listed.

在纽约的Marcellus页岩层上，对十一口家庭用水井进行了为期13个月的每月采样。这些水样被分析检测其中的溶解烃类（甲烷、乙烷、丙烷）及主要离子浓度（钙、镁、钾、钠、铵、硫酸根、氯、氟、溴、硝酸根）。对于浓度足够的井，还包括了每半年（2017年6月和12月）的甲烷和水同位素测量数据。此外，还列出了每月每口井的盐分可能来源及其概率。
