In the last two centuries, the impact of human activities on nature has been growing dramatically. Groundwater contamination by hazardous substances including organic contaminants has become a serious widespread problem, representing a substantial liability. An EPA survey in 1982 reported that 20% of drinking water wells showed contamination by synthetic organic chemicals. The combination of extensive use, volatility, accidental spills that occur during production, storage or transportation activities and chemical stability has led to widespread contamination of groundwater and soil by such ubiquitous and recalcitrant pollutants.

在过去的两个世纪里，人类活动对自然的影响急剧增加。包括有机污染物在内的有害物质对地下水的污染已成为一个严重的普遍问题，造成了巨大的损失。美国环保署1982年的一项调查报告称，20%的饮用水威尔斯井受到了合成有机化学品的污染。广泛使用、挥发性、在生产、储存或运输活动中发生的意外溢出以及化学稳定性等因素，导致地下水和土壤被这种无处不在的难降解污染物广泛污染。
