美国国家环境保护署(The U.S. Environmental Protection Agency,下面简称EPA) 是由美国国会设立用来保护本国的土地，空气和水资源。在国家环保法的规定，EPA就为和谐人类活动和保护自然生命的自然系统而努力实施相应的活动。所以EPA的研究项目就是为解决当今的环境问题,提供科学的知识，数据，技术及资金的支持。
“The U.S. Environmental Protection Agency is charged by Congress with protecting the Nation’s land, air, and water resources. Under a mandate of national environmental laws, the Agency strives to formulate and implement actions leading to a compatible balance between human activities and the ability of natural systems to support and nurture life. To meet this mandate, EPA’s research program is providing data and technical support for solving environmental problems today and building a science knowledge base necessary to manage our ecological resources wisely, understand how pollutants affect our health, and prevent or reduce environmental risks in the future.” (EPA, 1996；EPA-540, 2007)
国家危机管理研究实验室(The National Risk Management Research Laboratory，下面简称 NRMRL) 是EPA下属的一个调研中心，主要调研减少对人类健康和环境的危害的有效的环境技术和管理方法。这些方法的实验研究项目包括: 对空气，土壤，水，和地层资源的保护方法；公共水系统的水质保护方法；已被污染的现场和地下水的整治方法；防止和控制室内空气污染的方法。目标是: 努力去加速创新性的性价比高的环境技术的推广和实施；为EPA制定环保法提供科学和工程方面的信息和依据；
“The National Risk Management Research Laboratory (NRMRL) is the Agency’s center for investigation of technological and management approaches for reducing risks from threats to human health and the environment. The focus of the Laboratory’s research program is on methods for the prevention and control of pollution to air, land, water and subsurface resources; protection of water quality in public water systems; remediation of contaminated sites and ground water; and prevention and control of indoor air pollution. The goal of this research effort is to catalyze development and implementation of innovative, cost-effective environmental technologies; develop scientific and engineering information needed by EPA to support regulatory and policy decisions; and provide technical support and information transfer to ensure effective implementation of environmental regulations and strategies.”
Therefore, one of the missions for NRMRL is to support and organize demonstration projects for the innovative technologies, study and collect scientific data, and, finally, gether the technology principle, implement methods, and study and evaluation data into an “innovative technology Evaluation Report” to be published by EPA. DARAMEND soil remediation technologies and AQUABLOK capping technologies have been published as “innovative technology Evaluation Report” by EPA in 1996 and 2007, respectively.
