Measurement of static groundwater depth in a water well, as measured below land surface	`Agency= NMBGMR`
ObservedProperty	`Depth to Water Below Land Surface`	`depth to water below land surface` (NOTE: THIS IS NOT ELEVATION of Water, if elevation is reported, depth to water below land surface must be calculated using land elevation and measuring point.)	Option of Null, Dry, or qualifications on observed property
