Evaluation and optimization of in situ chemical oxidation for groundwater remediation

地下水是一种极其重要的、有条件可再生的自然资源，用于家庭和农业消费，并与地表水系统保持物理和化学平衡。多种有害有机化合物造成的污染对生态系统和人类构成迫在眉睫的健康风险，部分原因是这些化合物在地下环境中具有毒性和持久性。被以前的工业或其他用途污染的土地可能会闲置多年，对生产性重新开发构成障碍。在过去三十年中，在查明、调查和补救存在不可接受的污染程度的地点方面取得了重大进展。尽管作出了这一努力，但清理已知场址、有待发现的遗留场址和最近发生过溢漏和意外释放的场址仍将是一项重大挑战。在可预见的未来，将有大量资金用于修复

Groundwater is an immensely important and conditionally renewable natural resource that is used as a supply for domestic and agricultural consumption and sustains a physical and chemical balance with the surface water system. Contamination caused by a wide spectrum of hazardous organic compounds poses an imminent health risk to ecosystems and humans due, in part, to their toxicity and persistence in the subsurface environment. Land contaminated by former industrial or other uses may sit idle for years, posing a barrier to productive redevelopment. Over the last three decades there has been substantial progress to identify, investigate and remediate sites where an unacceptable level of contamination exists. Despite this effort, the clean-up of known sites, yet to be discovered legacy sites and sites where recent spills and accidental releases have occurred will be a major challenge. For the foreseeable future, a significant level of funds will be spent on the remediation of
