In sand, the indicated levels can bo considered <br />reliable ground water levels. In clay soil, it ts not possible to determine the ground <br />water level within the normal scope of a test boring investigation, except where lenses <br />or layers of more pervious waterbearing soil are present and then a long period of tinro <br />may be necessary to reach equilibrium. Therefore, the position of the water level syrr^ol <br />for cohesive or mixed texture soils may not indicate the true level of the ground water <br />table. The available water level information is given at the bottom of the log sheet. <br />SUBTERRANEAN ENGINEERING CORP.
