Sampling Results Overview

The Environmental Protection Agency posts results of air, water and sediment sampling along Talmadge Creek, the Kalamazoo River and Morrow Lake on their website. As new results become available, Enbridge will provide comparable sampling results validated by an EPA-approved laboratory.

Samples are collected to evaluate potential risks to public health and the environment. Environmental data is collected and analyzed in accordance with the EPA-approved Enbridge Sampling and Analysis Plan. All posted data has been validated in accordance with the EPA-approved Enbridge Quality Assurance Project Plan. These and other EPA-approved Enbridge work plans are available on the EPA’s website.

Sampling results are available as:

  • pdf - for viewing in free Adobe Acrobat Reader
  • csv - comma-delimited file viewable in Microsoft Excel or other spreadsheet software 
  • kml - interactive map viewable in Google Earth

Analytical results are posted on this website after data quality checks and validation are completed. The time between the collection of a sample and reporting to the website depends on the analytical procedure and level of data validation. Procedures for each compound are identified in our Sampling and Analysis Plan.

Air Monitoring and Sampling Results
