Note:	"The Neuman (1975) method assumes that the water level response is due to aquifer depressurization and dewatering.   In fractured rock, the delayed response is believed to be from the exchange of water between fractures and matrix rock.  Vertical anisotropy ratios are not reliable when reported for fractured rock. "
