首页/HOME -在地下水问题被做为重要的环保问题而提上日程之前，SSP&A已经在进行地下水相关问题的研究了。在管理方面，SSP&A一直积极地致力于应用地下水和环境科学来解决问题。在这个过程中，SSP&A做了从事大量的RCRA（资源保护与恢复法案）项目、CERCLA（综合环境反馈补偿和义务法案)项目以及州政府项目，同时也积累了大量通过谈判达成治理标准、治理目标、同意判决书等其它和场地修复相关文件的经验。无论涉及的技术、管理和法律的复杂性如何，SSP&A都努力达到我们的目标：用可行和经济合理的方法进行场地评价和修复。

Lone Pine Landfill - Freehold, New Jersey
A remedial investigation and feasibility study was performed for the off-site area surrounding the Lone Pine landfill, a Superfund Site. During the remedial investigation, field investigations were performed, and the data were analyzed to describe the hydrogeologic and chemical systems. Assessments of the extent and magnitude of existing contamination in the off-site area and of the potential for migration of this contamination in the ground and surface-water systems outside the landfill were conducted. In the feasibility study, potential remedial alternatives for the off-site area were evaluated in detail. A three-dimensional groundwater flow model was used to predict the effects of the various potential remedial actions on the hydrogeologic system.
Remedial alternatives that were considered and modeled included a slurry wall with french drain and impermeable cap, combined with various arrays of injection and extraction wells and interceptor trenches. A particle-tracking method was used in conjunction with the flow model to describe the direction and rates of groundwater flow associated with each simulation. A mixed linear-reservoir model was used to estimate the time required to achieve remedial goals for site clean-up. In addition, a study of the nature and volume of fluids at the site was completed to aid in the design of a leachate treatment system. SSP&A prepared all the documents required as part of the RI/FS process and participated in negotiations with the regulatory agencies for selection of the final remedy. PDF Figure
