由于对所涉化学品和化学性质的了解不全，很难评估化石燃料开采和农业等人类活动对地表水和地下水的污染。这对于通过水力压裂完成的威尔斯井的石油和/或天然气的附近提取对饮用水的潜在污染尤其如此。宾夕法尼亚州萨斯奎汉纳县，特别是宾夕法尼亚州迪莫克周围的非常规天然气开采引起了相当大的关注。我们分析了在整个萨斯奎汉纳县收集的地表水和地下水样本，并进行了补充生物测定和高分辨率质谱分析。我们发现，Ah受体活性与接近受损的气体威尔斯。我们还鉴定了某些化学品，包括所公开的水力压裂液添加剂，这些化学品在紧邻受损气井威尔斯或表现出生物效应的样品中。除了与钻井活动的相关性外，生物分析和高分辨率质谱法还检测到了其他人为来源产生的物质。我们的补充方法通过考虑生物效应和广泛的化学污染物筛选，提供了更全面的水质状况。
The contamination of surface water and ground water by human activities, such as fossil fuel extraction and agriculture, can be difficult to assess due to incomplete knowledge of the chemicals and chemistry involved. This is particularly true for the potential contamination of drinking water by nearby extraction of oil and/or gas from wells completed by hydraulic fracturing. A case that has attracted considerable attention is unconventional natural gas extraction in Susquehanna County, Pennsylvania, particularly around Dimock, Pennsylvania. We analyzed surface water and groundwater samples collected throughout Susquehanna County with complementary biological assays and high-resolution mass spectrometry. We found that Ah receptor activity was associated with proximity to impaired gas wells. We also identified certain chemicals, including disclosed hydraulic fracturing fluid additives, in samples that were either in close proximity to impaired gas wells or that exhibited a biological effect. In addition to correlations with drilling activity, the biological assays and high-resolution mass spectrometry detected substances that arose from other anthropogenic sources. Our complementary approach provides a more comprehensive picture of water quality by considering both biological effects and a broad screening for chemical contaminants.
