The Nevada Division of Environmental Protection (NDEP) staff will review and verify the submitted data. Upon approval, the data will be incorporated into the analysis for the 2026 NDEP Integrated Report (IR).

The purpose of the IR is to conduct a comprehensive analysis of water quality data associated with Nevada's surface waters. This report is prepared biennially under the Clean Water Act Sections 303(d), 305(b), and 314. It helps determine whether state surface water quality standards are being met and whether designated uses are being supported. The report is intended for use by the public, other entities, and NDEP for water quality management planning purposes.

More information on the IR can be found on the NDEP IR webpage.

NDEP is seeking electronic surface water quality data on the physical, chemical, and biological conditions within Nevada. For accuracy and reliability, all data should be collected using sound scientific principles.

While we prefer data in CSV format for ease of access, analysis, and integration, we may be able to work with different formats. If your data is in a different format, please reach out so we can determine if the data can still be utilized for IR analysis.

Anyone can submit data, including private citizens, public agencies, state and federal governmental agencies, non-profit organizations, and businesses.

October 1, 2019, and September 30, 2024.

The Nevada 2026 Water Quality Integrated Report assesses Water Year 2019 through Water Year 2024.

• Data must be from sampling events conducted between October 1, 2019, and September 30, 2024.

• Ensure that data was collected in accordance with established scientific principles and methodologies, while employing quality assurance methods. This approach guarantees that the data is credible, reproducible, and trustworthy for informed decision-making.

• Accurate location information preferably with maps if possible.

• Provide data with speciation and parameter names.

• Describe metals data as either dissolved or total.

• Submit numeric data in electronic form (spreadsheet or database).

• If in doubt, reach out and NDEP can help determine if data is viable.

Data should include (if available):

• Site location ID

• Waterbody name

• Location description

• Latitude and longitude

• Sample date and time

• Sample depth (if applicable)

• Parameter name

• Value of analyte (parameter)

• Unit of measure for all parameters

• Detection limit or reporting limit

• Analytical date

• Analytical method used

• Laboratory name used for analysis

• Comments about the data or sampling event
