Summary

The monitoring locations stored in Environmental Information Management (EIM) database.

Description

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. Data in EIM is collected by Ecology or on behalf of Ecology by environmental contractors - and by Ecology grant recipients, local governments, and volunteers. EIM Locations is a point feature service representing the monitoring locations from EIM. The locations consist of both surface locations for monitoring air, water, and habitat and wells for monitoring ground water. This feature service queries directly the EIM publication database which is updated nightly from the production transactional database.
