The proposed research will address the various mechanisms by which grout components could be released from the stabilized soil mass, and measure the resultant concentration of these components in the leachate. These concentrations will be determined by total organic carbon analysis and inductively-coupled plasma emission spectrophotometry, respectively. The toxicity characteristic leaching procedure will also be performed on the most promising of the formulations identified for each of the grouts investigated. Leachate characterization tests from soaking and permeation tests on samples excavated from the prototype grout bulbs and acute toxicity tests will also be conducted.

拟议的研究将解决浆液成分从稳定土体中释放的各种机制，并测量这些成分在渗滤液中的最终浓度。这些浓度将分别通过总有机碳分析和电感耦合等离子体发射分光光度法测定。毒性特性浸出程序也将在为所调查的每种浆料确定的最有希望的配方上进行。此外，还将对从原型灌浆球中挖出的样品进行浸泡和渗透试验，并进行渗滤液特性试验和急性毒性试验。
