Horizontal coordinate information is referenced to the North American Datum of 1983 (NAD 83) unless otherwise stated.
Vertical coordinate information is referenced to the National Geodetic Vertical Datum of 1929 (NGVD 29).
Altitude, as used in this report, refers to its distance above the vertical datum.
Transmissivity: The standard unit for transmissivity is cubic foot per day per square foot times foot of aquifer thickness [(ft3/d)/ft2]ft. In this report, the mathematically reduced form, foot squared per day (ft2/d), is used for convenience.
