The Maryland Department of the Environment (MDE) is currently requesting data for the 2018 Integrated Report (IR) of Surface Water Quality in Maryland. If your organization collected water quality data in Maryland within the past five-year period (2012-2016), please consider submitting your data. MDE is particularly interested in water quality data that are comparable to state water quality standards and criteria (e.g., temperature, dissolved oxygen, pH, turbidity, E. coli or enterococcus bacteria, various toxics, benthic macroinvertebrate and fish community data). Other water quality data, including conductivity, nutrient species, chlorophyll, habitat conditions, and field observations may also be used to assess ambient water quality.
Format: Data must be submitted in electronic format so as to facilitate statistical analyses. The Department prefers data to be in Microsoft Excel or Access formats. Please do not send paper or pdf of individual data sheets. Data reports are welcome but raw data should still be submitted as a separate spreadsheet (e.g. Excel document).
Metadata: Organizations must provide metadata that describe their data submission. The best way to do this is by providing a Quality Assurance Project Plan (QAPP). If a QAPP is not available, please submit other documentation that describes the following items:
Who conducted the sampling?
What water bodies were sampled?
What parameters were measured?
Over what time period were these parameters measured and with what frequency?
What was the purpose of sampling?
What specific field and laboratory methods and equipment were used for sample collection, handling, and analysis?
What quality assurance/quality control procedures were used? Description of calibration procedures?
To assist organizations in providing this information, MDE provides the 2018 Maryland IR Data Submittal Form.
Datasets: All water quality data should include information such as:
Name of the water body sampled
Date and time of measurements
Location of measurements in (latitude/longitude and NAD83 projection preferred, please provide projection if something other than NAD83)
Units of measurements
Field and laboratory measurements and analysis
Other relevant field or laboratory notes
To be used for the Integrated Report assessments, biological data must be collected according to the Maryland Biological Stream Survey (MBSS) protocols. Please see our Biological Data Quality Guidelines.
Due to the complexities of biological data submission, data submitters are strongly encouraged to contact Tim Fox prior submitting biological datasets. Mr. Fox can be reached at 410-537-3958 or alternately through email at Tim.Fox@maryland.gov.
