This Small Business Innovation Research project will demonstrate a novel membrane inlet for cone penetrometers instrumented for chemical detection in soil and groundwater. Cone penetrometers are now used to understand site geology at remediation sites. Cone penetrometers equipped with chemical sensors will reduce site remediation costs by allowing the currently required geophysical stuty to be combined with a chemical survey. This will minimize the number of expensive wells required. Further, chemical analyses, now routinely done in the laboratory at significant expense, will be done in the field. Field engineers will be able to make remediation decisions in real time at minimum cost. Recent efforts to instrument cone penetrometers have used large sophisticated laser systems which send light underground through fiber optic cable and return the signal to the surface for analysis. These systems can cost $250,000. This research will develop a membrane inlet for cone penetrometers which will make it possible to instrument a cone penetrometer with inexpensive, in-situ, chemical vapor sensors with a projected system cost of under $10,000. The phase I objective is to demonstrate a membrane inlet in the laboratory with typical chemicals found in remediation sites. The overall program objective is to built and demonstrate a fully operational cone penetrometer system at two remediation sites.

这个小型企业创新研究项目将展示一种用于土壤和地下水化学检测的锥形穿透仪的新型膜入口。锥形穿透仪现在用于了解修复场地的现场地质情况。装有化学传感器的锥形穿透仪将使目前需要的地球物理研究与化学调查相结合，从而减少场地修复的费用。这将最大限度地减少所需的昂贵井的数量。此外，化学分析，现在通常在实验室进行，花费很大，将在现场进行。现场工程师将能够以最小的成本实时做出修复决策。最近，锥形穿透仪的仪器使用了大型精密激光系统，通过光纤电缆将光发送到地下，并将信号传回地面进行分析。这些系统可以花费25万美元。这项研究将开发一种用于锥形贯入仪的膜入口，这将使使用廉价的原位化学蒸汽传感器测量锥形贯入仪成为可能，预计系统成本低于10,000美元。第一阶段的目标是演示在实验室中使用修复场地中发现的典型化学物质的膜入口。整个计划的目标是在两个修复地点建立并演示一个完全可操作的锥形穿透仪系统。
