Environmental Monitoring System (EMS)

EMS is the ministry's primary monitoring data repository. The system was designed to capture data covering physical/chemical and biological analyses performed on water, air, solid waste discharges and ambient monitoring sites throughout the province. 

It also contains related quality assurance data. Samples are collected by either ministry staff or permittees under the Environmental Management Act and then analyzed in public or private sector laboratories. The majority of such monitoring data is entered into EMS electronically via Electronic Data Transfer (EDT). 

EMS data is typically available in formatted hard copy reports or electronically in comma delimited (e.g., .csv) files as: 

  • Monitoring location-related data 
  • Sample and results-related data
