PENETRATION/EXCAVATION RESISTANCE
L            Low resistance . Rapid penetration possible with little effort from the equipment used
M            Medium resistance. Excavation possible at an acceptable rate with moderate effort from equipment used
H            High resistance to penetration/excavation. Further penetration is possible at a slow rate
R            Refusal or Practical Refusal. No further progress possible without the risk of damage or unacceptable wear to the digging implement


These assessments are subjective and are dependent on many factors including the equipment power, weight, condition of excavation or drilling tools,
and the experience of the operator.

WATER
                                        Water level shown at date                                                  Partial water loss
                                        Water inflow                                                               Complete water loss

GROUNDWATER NOT                         The observation of groundwater whether present or not, was not possible due to drilling water, surface seepage or cave in
OBSERVED                                of the borehole/test pit.
GROUND WATER NOT                        The borehole/test pit was dry soon after excavation. However, groundwater could be present in less permeable strata.
ENCOUNTERED                             Inflow may have been observed had the borehole/test pit been left open for a longer period.
