Data Water Quality Standards Sampling and Monitoring Guidance References and Resources
Indiana Water Monitoring Inventory
The Indiana Water Monitoring Inventory is a Google Map application that serves as a portal for locating water monitoring information in the state of Indiana. You may search the monitoring inventory by location, parameter type, or agency/organization who conducted the sampling. Every monitoring location within the Inventory contains a URL link to either the actual data (if they are available on-line) or contact information for the person or program responsible for the monitoring data.
IDEM Indiana Water Quality Atlas
The Indiana Water Quality Atlas (IWQA) uses geographic information systems (GIS) tools to focus specifically on Indiana’s water quality as affected by land use change.
IDEM Assessment Information Management System (AIMS) Database
Tabular download and graphical presentation utility of the Indiana Department of Environmental Management (IDEM) water quality database. Accessed through the Indiana Water Quality Atlas (IWQA) Web portal.
USGS NAWQA Data Warehouse
The U.S. Geological Survey (USGS) began its NAWQA (National Water Quality Assessment) program in 1991, systematically collecting chemical, biological, and physical water quality data from 42 basins across the nation. The data warehouse currently contains and links data concerning chemical concentrations in water, bed sediment, and aquatic organism tissues for about 3,100 chemical constituents; site, basin, well and network characteristics with many descriptive variables; daily stream flow information for fixed sampling sites; and groundwater levels for sampled wells.
USGS National Water Information System: Surface Water
The U.S. Geological Survey's (USGS) National Water Information System (NWIS) is a comprehensive and distributed application that supports the acquisition, processing, and long-term storage of water data. Indiana surface-water information includes time-series data that describe stream levels, stream flow (discharge), reservoir and lake levels, surface-water quality, and rainfall.
USGS National Water Information System: Water Quality
The U.S. Geological Survey (USGS) collects and analyzes chemical, physical, and biological properties of water, sediment and tissue samples from across the Nation. The discrete sample data is a large and complex set of data that has been collected by a variety of projects ranging from national programs to studies in small watersheds. Users should review the help notes and particularly the data retrieval precautions before beginning any retrieval or analysis of data from this data set.
IDNR Hoosier Riverwatch Searchable Database
Hoosier Riverwatch promotes stewardship of Indiana's waterways through a volunteer stream monitoring and water quality education program. The database is searchable by 8-digit hydrologic unit code (HUC) through an interactive map.
USGS National Water Information System: Groundwater
The U.S. Geological Survey's (USGS) National Water Information System (NWIS) is a comprehensive and distributed application that supports the acquisition, processing, and long-term storage of water data. The groundwater database consists of records of wells, springs, test holes, and excavations. Available site descriptive information includes well location information such as latitude and longitude, well depth, and aquifer.
IDNR Ambient Ground Water Chemistry
Database from the Indiana Department of Natural Resources, Division of Water (IDNR, DOW; CD-ROM or downloadable) contains ambient groundwater chemistry analyses for samples in the following water-management basins: St. Joseph (1997), Whitewater (1988), Kankakee (1990), Lake Michigan (1994), Maumee (1996), West Fork White River (1999). Full publications concerning the water resources of these basins are available on the IDNR, DOW Web site. GIS shapefiles of the point values are included, as well as metadata for each data set.
IDNR Water Well Record Database
The Indiana Department of Natural Resources, Division of Water (IDNR, DOW) currently maintains, in original paper and digital form, the records of nearly 373,000 water wells drilled in Indiana. Of this number approximately 138,000 records have been field verified. This online database provides access these public records, with several available search options. It is recommended by IDNR that first time users of this online database familiarize themselves with the About this Service and Database Search Help pages.
IDNR Water Well Record Viewer
The Indiana Department of Natural Resources, Division of Water (IDNR, DOW) currently maintains, in original paper and digital form, the records of nearly 373,000 water wells drilled in Indiana. Of this number approximately 138,000 records have been field verified. The well record viewer is an interactive Web mapping application that plots the locations of water wells in Indiana, noting those with verified locations versus those with estimated locations.
IDNR Significant Water Withdrawal Facility Data
The Indiana Department of Natural Resources, Division of Water (IDNR, DOW) currently maintains information and water-use data submitted by owners of significant water withdrawal facilities. These users are required to register with the DNR and report water use on an annual basis. A “significant water withdrawal facility” is defined to mean those that have the capability of withdrawing more than 100,000 gallons of groundwater, surface water, or both in one day. Prior to using the data, the IDNR recommends that you review the metadata (data explanation) document, which will help you to better understand the limitations of the data.
IDEM Indiana Safe Drinking Water Information System (SDWIS)
Tabular summaries of public water supply systems with ability to examine water-quality parameters that are monitored, along with maximum contaminant load (MCL) levels for each parameter. Actual sample results are not made available on this site. The database is made available through Indiana Department of Environmental Management (IDEM).
USEPA Drinking Water Data and Databases
The U.S. Environmental Protection Agency (USEPA) maintains drinking water data in several databases, including the Safe Drinking Water Information System - Federal Version (SDWIS/FED) and the National Contaminant Occurrence Database (NCOD). The agency utilizes this information to help manage environmental programs, and provides public access to the data through the Internet.
USEPA Envirofacts Data Warehouse: Water
Envirofacts is a single point of access to select U.S. Environmental Protection Agency (USEPA) environmental data. This Web site provides access to several USEPA databases to provide you with information about environmental activities that may affect air, water, and land anywhere in the United States. With Envirofacts, you can learn more about these environmental activities in your area or you can generate maps of environmental information.
