How do I search EIM?

Basic search
Use the form provided to specify your search criteria. Results are returned in a list with options to view metadata, plot data locations to a map, or download a dataset, etc.

  1. The EIM Search page is now an all-in-one form. You can search by three primary categories (Studies, Locations, and Results) individually or all at once.
  2. Use the form to specify your search criteria.
  3. Click "Search Data."
  4. A list of results meeting your search criteria will be returned.
  5. Click on the appropriate link, tab, or drop-down list to view metadata, plot to the map, or download a dataset, etc.

Map search
Navigate a map of Washington to pick an area or specific locations from which data is desired, using interactive map tools.  The locations and associated results can then be transformed into a list for viewing and downloading the data.

  1. From the EIM Search page, click the map.
  2. Refer to "Help" on the map page for information on how to use the map tools and data layers.

Advanced search
For a particular parameter, advanced search allows you to filter the data by specifying the Sample Matrix, Result Value Units, and Result Basis (wet or dry) in which you want the Results displayed.  In this process, EIM converts dissimilar Units to Units of choice.  Advanced search also allows you to specify a Result Value range.  This is useful if you want to see which Results exceed or are within a specific regulatory limit, etc. 

  1. Use basic search to generate a list, then choose the Parameters tab. Choose "Advanced Search" from the drop-down list for the parameter of interest.
  2. This will open a form in which you can specify the Sample Matrix, Result Value Units, Result Basis, and Result Value range for that parameter.
  3. Click "Search."
  4. A list of results meeting your search criteria will be returned.
  5. If you click Map All, you can look at the exceedances on the map.

Example of Advanced Search form.

How do I download data from EIM?

Search and download
When Basic, Map, or Advanced Search results are returned, there is an option to download the data in the list.  Clicking "Download" will export the data to a ZIP file containing a CSV (comma separated variable) file or files suitable for importing into a spreadsheet (like MS Excel) or a database (like MS Access).

What is metadata and how do I use it?

Metadata provides detail about data
Metadata is "data about data." EIM refers to metadata as "detail," containing information for Studies (purpose, QA level, bibliographic link, etc.), Locations (setting, geographic detail, etc.), Field information (start date, data collector, sample matrix, etc.), Parameters (CAS number, etc.), and Methods (category, description, etc.).  Well data is included under Locations and includes details about well construction and use, etc.

How to access metadata
Metadata is accessible from search lists by clicking the drop-down arrow next to a record.  For example, to view Study metadata, click the drop-down arrow for the desired Study.  This will open a page displaying Study detail.  Metadata is also incorporated into the downloadable files, as explained above in How do I download data from EIM? - Search and Download.

Example of a Location metadata page.

What are the reference tables?

Valid values for parameters, methods, units of measure, labs, taxa, and tissue types
Reference tables, also known as lookup tables, contain valid values for EIM parameters, methods, units of measure, labs, taxa, and tissue types.  There are also valid value sets that aren't updated as often, like sample source, data qualifier, and study type.

You can view the reference tables via the link below or when you are logged in to our Submit Data page.  Ecology employees can see the reference tables by going to the EIM Loader and Editor.

To see changes (additions, deletions, modifications) that have been made to the reference tables from 2005 forward, please see the following document.  It's an Excel document that you can filter and sort.
