DESCRIPTION: Since the early 1980s, the Geological Survey
Bureau has developed and maintained an extensive database on
municipal and rural water systems.
NUMBER OF DATA POINTS: MWSI currently contains information
for 3,854 active and abandoned municipal wells and summary
information for 859 municipal and rural water supplies.
LOCATION ACCURACY: The location of each municipal well is
accurate to <100 feet where location information is
available, or where wells were field checked.
SIGNIFICANT DATA ELEMENTS: MWSI contains information about
the municipal or rural water system (facility name, address,
contact person, water use, number and type of sources, etc.),
each active well (name, location, availability, well
construction, capacity, geology, aquifer) and surface water
supply (name, location, availability).
AVAILABILITY: Summary information for municipal water
supplies and municipal wells is available upon request from a
staff geologist. Currently, computerized reports for
municipal and rural water supplies are available as printouts
for most municipal water supplies for their active water
sources (primarily wells) only.
