地下水污染研究正变得越来越重要，特别是在确定具体污染源的能力方面。在大多数情况下，地下水污染研究是以地下水的一般物理和/或化学特征为基础的，只提供关于某一含水层的某一特定样本是否受到污染的资料。利用仪器中子活化分析与主成分因子分析和化学质量平衡相结合的技术已被证明是帮助区分几种可能的地下水污染源的有用工具。此外，这项技术已被用来分摊每个污染源的相对贡献。
Groundwater contamination studies are becoming more important particularly concerning their ability to identify specific sources of the contamination. In most cases, groundwater contamination studies are based upon general physical and/or chemical characterization of subsurface waters and provide information only as to whether a specific sample from a particular aquifer is being contaminated or not. A technique utilizing instrumental neutron activation analysis together with principal componene factor analysis and chemical mass balances has been shown to be a useful tool in helping to differentiate among several possible sources for groundwater contamination. In addition, this technique has been utilized to apportion relative contributions from each source of contamination.
