概括

自20世纪80年代以来广泛使用的地下水污染补救的和处理方法,由于从各种来源去除污染物的局限性,往往无法实现完全的清洁. 这种方法经常会增加需要处理的污染水量,延长整治工作的时间.

科学领域:

环境科学环境科学
水文地质学水文地质学
环境工程环境工程

背景情况:

美国在水质监管方面有着悠久的历史,推动了污染物运输,地点表征和修复技术的进步.
从20世纪80年代开始,和处理 (PAT) 是占主导地位的地下水污染补救方法,到1982年,它被用于所有美国超级基金地下水补救决定中.
1992年以后,PAT申请减少了,原因是它在实现完整的场地整治和关闭方面的记录不足.

研究的目的:

批判性地重新评估和处理方法在地下水整治中的有效性.
突出了和处理在处理NAPL,吸附和低透度矩阵中的污染物的局限性.
根据和处理的固有缺点,提出对补救策略的重新评估.

主要方法:

在美国超级基金地下水补救决定中应用和处理技术的历史趋势的审查.
分析限制和处理效率的因素,特别是各种环境矩阵中的污染物质量.
评估和处理的后果,例如延长清洁时间和增加处理的地下水量.

主要成果:

美国超级基金地区的和处理应用在1982年达到顶峰,随后下降,这表明人们认识到其局限性.
非水相液体 (NAPL),吸附相和低透度矩阵中的污染物质量显著阻碍了和处理的有效性.
和处理方法往往导致长时间的整治期,并产生大量受污染的地下水.

结论:

抽水处理,尽管在历史上普遍存在,但对于完全的地下水整治,它往往是低效的.
该方法在处理反抗性污染源方面的局限性可能会加剧地下水污染问题.
重新评估整治策略是必要的,以克服和处理的固有缺点,并改善清理结果.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
