The Effect of Calcium Magnesium Acetate (CMA) Deicing Material on the Water Quality of Bear Creek, Clackamas County, Oregon,1999
Entry ID: WRIR_00-4092

[ Update this Record ]

Summary
Abstract: This study was done by the U.S. Geological Survey, in cooperation with the
Oregon Department of Transportation (ODOT), to evaluate the effects of the
highway deicing material, calcium magnesium acetate (CMA), on the water quality
of Bear Creek, in the Cascade Range of Oregon. ODOT began using CMA (an
alternative deicer that has fewer adverse environmental effects than road salt)
in the mid-1990s ... View entire text

Quality Quality control samples comprised about 15 percent of the water-quality
samples for the project. Field blanks for biochemical oxygen demand and
dissolved organic carbon were prepared by putting commercially available
organic-free water through all of the sampling and filtering steps in the
field. Field blanks for major ions, trace elements, and nutrients were
prepared using inorganic-free water. Replicate samples were prepared by
collecting two grab samples from the stream at nearly the same time.
