Biogeochemistry Laboratory in Fort Collins, CO.
Biogeochemistry Laboratory in Fort Collins, CO.
The Fort Collins Biogeochemistry laboratory is a state of the art facility operated by the Air, Water, and Aquatic Environments (AWAE) program at the Rocky Mountain Research Station. Equipped with cutting edge instrumentation and experienced staff members, the biogeochemistry lab provides a wide range of analytical abilities for research pertaining to environmental chemistry.  Instrumentation and analysis methods are continually updated to remain at the forefront of modern science and to meet on-going needs of biogeochemical research projects pertaining to water quality, soil productivity, forest disturbances, soil and aquatic restoration, climate change and long term monitoring studies.

Analytical Support & Collaboration

In addition to providing support for AWAE and RMRS scientists, the Biogeochemistry Laboratory commonly assists other government agencies, academic institutions, and private research entities with a variety of analytical needs.  Current program research and collaborations include analysis support for the Fraser Experimental Forest, Glacier Lakes Ecosystem Experiments Site, Loch Vale Watershed Research and Monitoring Program, and the USGS Rocky Mountain Regional Snowpack Chemistry Monitoring Study.

Biogeochemistry Methods and Analysis Capabilities

We offer water sampling analysis, with analytical package customized for specific needs. Please contact the Biogeochemistry Laboratory for further information (970-498-1017).
