<br /> I BORING WGS: GROUND WATER INFORMATION <br /> __GrOUnd water information is shown under "Water Level Measurements" at the bottom of the log and in the "Me" <br /> I (moisture condition) column on the right side. Because the presence of water in the soil and the level of the ground <br /> water table can change over time, the information presented is accurate only for the date and time the observations <br /> I and measurements were made. <br /> I The following information (in addition to the sampling date and time) appears under "Water Level Measurements:" <br /> I . The sampled depth, which is the lowest depth of soil sampling at the time of measurement. <br /> - <br /> I . The casing depth, which is the depth to the bottom of the casing or hollow-stem auger at the time of <br /> measurement. <br /> I . The cave-in depth, which is the depth at which the measuring tape stops in the bore hole. <br /> I . The water level, which is the point in the bore hole at which free-standing water is encountered with the <br /> . measuring tape. <br /> . The drilling fluid level is similar to the water level, except that the liquid in the bore hole is drilling fluid. <br /> I <br /> I The water level, drilling fluid level, and cave-in depths are measured with a weighted measuring tape. <br /> I The "Me" column indicates the moisture condition of soil samples. A "n" in the column means that a soil sample <br /> appears dry (absence of moisture, dusty, dry to touch); "M" means moist (damp but no visible water), and "W" <br /> I means wet (visible free water). An "F" is used if the sample is frozen. <br /> I The water level symbol -L in the "Me" column indicates the estimated position of the ground water table in <br /> the boring. The absence of the water level symbol on a log does not necessarily mean that ground water was not <br /> encountered or that the water table or piezometric surface was DOt penetrated. <br /> I <br /> Overall, determining the position of the ground water table is an interpretative process that depends on such factors <br /> I as water level measurements, the presence and type of drilling fluid, the condition of samples, subsurface <br /> f conditions, site conditions, whether the bore hole is covered or open, and weather conditions. Because of these <br /> factors and those noted previously, the actual ground water level in the field may vary from that shown on the <br /> boring logs. <br /> I <br />
