 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 the equipment used.
        H              High resistance to penetration/excavation. Further penetration is possible at a slow rate and requires significant
                       effort from the equipment.
        R              Refusal or Practical Refusal. No further progress possible without the risk of damage or unacceptable wear to the
                       digging implement or machine.
 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

 GROUNDWATER NOT                                    The borehole/test pit was dry soon after excavation. However, groundwater could be present in
 ENCOUNTERED                                        less permeable strata. Inflow may have been observed had the borehole/test pit been left open
