  • Ground water well sampling - Sampling ground water for contamination
  • Flow metering - Design, implement, and operate, computer controlled, site specific automated flowmeters to provide flow data for storm water system analysis
  • Lake/pond level monitoring - Design, implement, and operate, level monitoring equipment to determine the water depths in lakes and ponds throughout the state
  • Compliance sampling - Expert site specific water sampling conducted to evaluate potential areas of noncompliance as mandated by the MPCA
  • Current projects

Air quality

  • Background sampling - Continuous pre-construction background carbon monoxide monitoring to ensure that public safety is not impacted by any proposed transportation related project
  • Safety monitoring - Continuous carbon monoxide monitoring and fresh air ventilation activation to insure public safety while traveling thru special tunneled highway areas
  • Ambient compliance sampling - Continuous carbon monoxide monitoring to fulfill Clean Air Act requirements regulated by the MPCA
  • Air quality modeling - EPA approved computer modeling provides hot spot analyses to determine projected carbon monoxide concentrations at proposed intersections
  • Current projects
