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.

    Metals, PCBs, etc.
  • Physical measurements
    Water clarity, flow, temperature, groundwater levels (including transducer data), etc.
  • Biological measurements
    Fish measurements, plant tissue, benthic organisms, bioassay data, etc.
  • Habitat data
    Habitat metrics
  • 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 sources
Data in EIM is collected by Ecology or on behalf of Ecology by environmental contractors - and by Ecology grant recipients, local governments, and volunteers.
