Nutrients Division

Storrs
Center for Environmental Sciences and Engineering

The Nutrients Division determines concentrations of nutrient series such as nitrogen, phosphorus, silica, and carbon constituents in fresh, brackish, and saline water samples, as well as in solid matrices, including sediment and filters. This laboratory is certified by the Connecticut Department of Public Health for the analysis of nutrients in non-potable waters.
