The NGWMN Data Portal is the access point for
information about the wells in this network and for their
related lithology (geology), construction, water-level and
water-quality data. To access the portal click here. To
learn how to use the portal click here.
An important aspect of the NGWMN Data Portal is that it
is not an aggregated database of data from all
participants, but is a gateway to the data which are
maintained and served by each participating organization.
Original data are retrieved from each data provider by the
portal. Data from each provider is refreshed nightly to
create a cached data set to allow queries to the data to be
faster. These data are then transformed into a consistent
format to serve out to the NGWMN Data Portal.
The Data Portal has filters and map-based selection
capabilities that allow the user to select the sites of
interest. After the sites are selected, requests are sent
to cached database to obtain the data. These data are then
returned via the portal in graphs and tables and can also
be downloaded for later use.
Queries can be made on network type (Water Level or
Water Quality), well classification, and monitoring
category. Sites can also be queried based on Principal
Aquifer, type of data available, contributing agency, and
Development work on the portal is proceeding according
to a5-year plan
created in 2018.
Web service requests may be submitted to obtain data
directly and to bypass the NGWMN map interface. Currently
only basic site information and water levels are available
through web service requests. For full site information,
lithology, construction information or water quality data
