ABSTRACT
EPA has determined a number of compounds to be associated with hydraulic fracturing. These compounds include but are not limited to glycols, glycol ethers, phenols and others. The EPA has included several of these compounds in their National Hydraulic Fracturing Study that is intended to measure the impact of hydraulic fracturing on groundwater and surface water sources.
Portland cements and Bentonite products are used in monitoring well and water well construction. However, in the processing and manufacture of these materials, some of the compounds studied in the EPA study may be present. A review of manufacturing procedures indicates that glycols, glycol ethers, phenols and others can be employed as grinding aids in the manufacture.
A study was conducted to determine whether these compounds could be detected and were present in several Portland cements and bentonite products. A second phase of the study was to conduct leaching studies on a cured cement sample from one of the brands initially analyzed. The results of these studies and the possible implications for future work will be explored.
