本文介绍了一种新型地下水监测系统--BAT系统，该系统包括以下功能：（a）对大多数类型土壤中的地下水进行采样，（B）测量孔隙水压力，（c）原位测量水力传导系数。该系统还可用于示踪剂测试。该系统利用一个永久安装的过滤嘴连接到钢管或PVC管。通常通过将尖端向下推到所需深度来进行安装。过滤嘴也可以埋在垃圾填埋场下面。新系统的主要特点是过滤嘴包含一个自密封快速连接装置，可以临时将过滤嘴连接到适配器上，以实现各种功能，例如水取样以及测量孔隙压力和水力传导率。这项新技术使加压水和气体的采样成为可能。样品直接在密封、预灭菌的样品筒中获得。地下水的取样和孔隙压力的测量可以在很长一段时间内重复进行，精度不降低。这种技术也非常适合从饱和和非饱和区的土壤剖面中的不同地层中采集水样。实际安装深度为0.5至60米。
This paper describes a new system for ground water monitoring, “the BAT System,” which includes the following functions: (a) sampling of ground water in most types of soils, (b) measurement of pore water pressure, and (c) in situ measurement of hydraulic conductivity. The system can also be used for tracer tests. The system utilizes a permanently installed filter tip attached to a steel or PVC pipe. Installation is normally performed by pushing the tip down to the desired depth. The filter tip can also be buried beneath a landfill. The primary feature of the new system is that the filter tip contains a self-sealing quick coupling unit, which makes it possible to temporarily connect the filter tip to adapters for various functions, e.g. water sampling and for measurement of pore pressure and hydraulic conductivity. The new technique makes sampling of both pressurized water and gas possible. Samples are obtained directly in hermetically sealed, pre-sterilized sample cylinders. Sampling of ground water and measurement of pore pressure can be repeated over a long period of time with undiminished accuracy. This technique is also well-adapted for taking water samples from different strata in a soil profile, in both the saturated and unsaturated zones. Actual installations range from 0.5 to 60m depth.
