Frequently Asked Questions

  • Why should I contribute data to the EMD?
    Volunteer groups and other small organizations may want to contribute data to the EMD to preserve their data for the future, make it accessible to the public, and/or provide data for use in the surface water quality assessment process. Labs and consultants will likely contribute data to meet permitting or other requirements for their clients – if allowed by the regulatory/monitoring program.

  • How can I query for data in the EMD?
    All finalized data can be queried for by going to the EMD’s OneStop Data Retrieval web page. Once a type of data is selected (grab samples or time series results from automated data loggers), guidance on how to query is provided via links at the top of the respective query form. For data to be returned, it must meet all of your query parameters. If you enter conflicting specifications (such as searching for estuarine type stations and data for a particular lake), no data will be returned. The available query is intended for general querying of the EMD. Site remediation professionals should note that a query specifically designed to report contaminated site data is under development.

  • What do I get when I query the EMD?
    If your query was successful, you will receive an email with a link to your results. It may take a few minutes to a few hours to receive your results depending on the complexity of your query and the amount of traffic on the server. The link will lead to a spreadsheet which will contain the data results and also the query parameters used to construct the results for your reference. The spreadsheet can be opened via a web browser or saved as a Microsoft Excel file. If your query was unsuccessful (no data rows were returned), you will be notified by the web query form and prompted to modify your query.

  • Is there a charge for obtaining the data?
    No, the data is available for free.

  • How often is the data updated in the EMD?
    The EMD houses data for many projects – each having their own time frame for sampling and updating the data. Some projects are updated as the data is finalized by the lab while others are updated after the end of the sampling season. Other projects have been completed and no further updates are made. Once finalized data is incorporated into the EMD, it is available on the OneStop retrieval web site the next day.

  • What is the quality of the data in the EMD?
    The quality of data varies by project and the intent or purpose of the sampling. Users are encouraged to contact the project contact (listed in the data results returned) for details on data quality if it cannot be gleaned from the info provided in the EMD.

  • Do I need to cite the data if I use it in a report, presentation, or some other product?
    Yes, the data should be properly cited. Citation information is available through the project bibliography.

  • Is the EMD data available from EPA’s national STORET warehouse?
    Some of the data in the EMD has been sent to EPA’s national STORET warehouse. A majority of it has not been sent due to lack of resources to upload and maintain it and/or lack of required metadata.
