Accidental contaminant spills in surface freshwater drinking sources put the public at risk, lower consumer confidence, and are costly to clean up. Although crude oil is commonly transported in close proximity to drinking water supplies, much of the research has focused on the fate and transport of crude oil in marine and riverine systems, not reservoirs. This study illustrates an application of a proactive spill modeling method to simulate crude oil fate and transport in a reservoir using a combination of laboratory and modeling investigation. Dissolution trends of benzene, toluene, and ethylbenzene from hypothetical accidental input scenarios were estimated by solid-phase micro-extraction combined (SPME) with gas chromatography mass spectrometry (GC/MS) methods. Laboratory dissolution trends informed inputs to a hydrodynamic and water quality model, CE-QUAL-W2, which simulated the fate and transport of the crude oil components within a reservoir with a focus on water quality impacts at the drinking water intake. The method can be applied to proactively quantify and scientifically guide emergency response planning and management of drinking water reservoirs in the event of an accidental crude oil spill.

偶然的污染物溢出到地表淡水饮用源中使公众处于危险之中，降低了消费者的信心，并且清理成本很高。尽管通常在靠近饮用水源的地方运输原油，但许多研究都集中在海洋和河流系统（而不是储层）中原油的命运和运输上。这项研究说明了一种主动溢流建模方法的应用，该方法通过结合实验室和建模研究来模拟油藏中的原油命运和运输。通过固相微萃取组合（SPME）和气相色谱质谱（GC / MS）方法估算了假设的偶然输入情景下苯，甲苯和乙苯的溶解趋势。实验室的溶解趋势为水动力和水质模型CE-QUAL-W2提供了信息，该模型模拟了油藏中原油成分的去向和运输，并着重研究了饮用水对进水口水质的影响。该方法可用于在发生意外原油泄漏的情况下主动量化和科学指导饮用水水库的应急响应计划和管理。
