Table 6 –Major chemical constituents in water form wells and springs

Data retrieved from WATSTORE: the U. S. Geological Survey’s National Water Data Storage and Retrieval System.

Local Identifier – same as Location in Table 1.

Location.—The Location of a well or spring is described by using the system of quartering by sections (example: 11.05.13.112) or the Navajo system for the Navajo Reservation (example: 33-7.16X8.96). The Systems are explained in the text. Not all locations have been field checked by U. S. Geological Survey. All locations are defined as accurately as possible with the information available.

Date of sample – Date sample was collected (year, month, day).
