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