Concrete was used during construction of geotechnical borehole United States Geological Survey (USGS)-142, and cement overflowed into the section of the borehole where water levels were needed to be measured. The purpose of this revision is to drill an additional borehole, USGS-142A, approximately 10 to 25 feet from USGS-142 in order to measure water levels.
