CSS supports the Environmental Protection Agency with assessing contamination within abandoned mines. There are thousands of abandoned mines throughout the western United States. Many of these mines are leaching heavy metals into nearby streams or have contaminated soils causing vegetation die off.  

CSS employee owners conduct field work to assess the extent of this contamination. During field excursions, staff collect soil and water samples and characterize the extent of contamination. The team analyzes sample on site and in the laboratory for heavy metals. This information informs remediation plans for contaminated sites.
