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，用作家庭和农业消费的供应品，并维持与地表水系统的物理和化学平衡。各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威胁，部分原因是它们在地下环境中的毒性和持久性。被以前的工业或其他用途污染的土地可能会闲置多年，对生产性的重新开发构成障碍。在过去三十年中，在确定、调查和补救存在不可接受程度的污染的地点方面取得了重大进展。尽管做出了这一努力，但清理已知遗址、尚未发现的遗留遗址以及最近发生泄漏和意外泄漏的遗址将是一个重大挑战。在可预见的将来，将花费大量资金用于补救

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
