What is EIM?
The Environmental Information Management System (EIM) is the Department of
Ecology's main database for environmental monitoring data. EIM contains records
on physical, chemical, and biological analyses and measurements. Supplementary information about the data (metadata) is also stored, including information about environmental studies, monitoring locations, and data quality.
A searchable database
Search over 15 million environmental records from 118,000 monitoring locations
throughout and adjoining Washington state. Access data from over 3700 studies including information about where samples were collected,
study details, and data quality.
Search by map
Search for environmental data by navigating a map of Washington state.
Search and download
Conduct a custom search for environmental datasets
by form or by map, then download for analysis.
Use an advanced search, download and analysis tool.
- Big changes in 2013
On August 1 3013 we launched a new Search app with a slick new map, updated many fields in the database to better meet the needs of our customers
and the data we receive, added the ability to accept time series data
from field instruments, and added more customized search pages for looking at
specific data types. See more info in our
2013 Changes document.
- Groundwater Data Center
Groundwater Data Center is a special portal and search for EIM users
interested in groundwater data and wells.
What's in EIM?
Metals, PCBs, etc.
Water clarity, flow, temperature, groundwater levels (including transducer data), etc.
Fish measurements, plant tissue, benthic organisms, bioassay data, etc.
- Study information
Study purpose and contact information, data quality,
links to bibliographic information, etc. Studies range from statewide
ambient stream monitoring to hazardous waste site cleanups.
- Location information
Detailed physical and geographical information about monitoring locations.
Includes information about well construction and use, when available.
Data in EIM is collected by Ecology or on behalf of Ecology by
environmental contractors - and by Ecology grant recipients, local governments,
