Long Term Monitoring and Testing of Waste Paper Sludge Landfill Covers

*** 9908150zimmih此拨款支持继续对两个现有堆填区进行长期监测和原位测试。利用废纸污泥作为垃圾填埋覆盖物是一种极好的回收和再利用方法，并且具有经济效益。污泥可以用来代替压实粘土层或土工膜，这通常被用作不透水的屏障层。这些垃圾填埋场是第一个在他们的州（纽约州和马萨诸塞州）利用废纸污泥作为覆盖系统的不透水屏障层。在其中一个地点，覆盖层是用压实粘土建造的，这样就可以直接比较纸污泥帽和粘土帽的行为。这是独特的数据，很少或根本没有这样的长期数据存在。这些垃圾填埋场的监测工作在5到7年前开始，这笔资金将用于更换一些设备和与数据采集相关的现场活动。* * *

***9908150ZimmieThis award supports the continuation of the long term monitoring and insitu testing of two existing landfills. The use of waste paper sludge aslandfill covers is an excellent recycling and reuse methodology, andeconomically beneficial as well. The sludge can be used to replacecompacted clay layers or geomembranes, which are usually utilized as theimpermeable barrier layer.These landfills were the first in their states (NY and MA) to utilize wastepaper sludge as the impermeable barrier layers in the cover systems. Atone of the sites, the cover was constructed using compacted clay in places,so that direct comparisons can be made between the behavior of the papersludge cap and a clay cap. This is unique data, and little or no suchlong-term data exists.Monitoring at these landfill sites began between 5 and 7 years ago, andthis award will fund the replacement of some equipment and the fieldactivities associated with data acquisition. ***
