Groundwater

  • More than 500 groundwater monitoring wells extending to both shallow and deep aquifers have been installed within and outside the site to ensure the community is protected. Samples from the wells are frequently collected and analyzed in a laboratory under strict quality guidelines, and the results are widely distributed. Recent results can be found here. 
  • Businesses and residents in the area receive their drinking water from the City of Aurora and East Cherry Creek Valley Water and Sanitation District, with the exception of a few properties served by private wells that have tested clean.
  • A groundwater extraction and treatment response north of the site has significantly decreased waste concentrations, and they continue to decline.
