We encourage everyone who uses this data to help us check for mistakes or omissions (email us if you find problems). Also, please contact us if you would like to donate information to be incorporated in our databases. The "quad" designation definition and a conversion program between latitude & longitude, state plane and quad is available. All latitudes and longitudes are in decimal degree format and GPSed wells use NAD 83 (horizontal) and NAVD88 (vertical). Ground water climatic response is best seen in the Drought Indicator Wells subset of the network.
