The Environmental Service Program's Chemical Analysis Section staffs the only State of Missouri Environmental Laboratory. The Chemical Analysis Section is the state's primary laboratory for drinking water chemistry and environmental chemistry and provides analytical testing and support vital in protecting Missouri’s residents and natural resources. This section provides analytical support for programs throughout the department and for other state agencies.

Chemists and staff use their expertise and state of the art instruments to identify and confirm various contaminants, both natural and man-made. These contaminants include:

  • Organic compounds.
  • Synthetic organic compounds.
  • Heavy metals.
  • Biological contaminants.

These contaminants may affect health, water quality and natural resources.  The Chemical Analysis Section provides the data necessary to evaluate and make decisions concerning the air and water quality in Missouri. In addition, the section also performs drinking water testing, which includes:

  • Physical properties.
  • Metals.
  • Inorganic nonmetallic constituents.
  • Aggregate organic constituents.
  • Organic compounds.


Our measurements impact the public on a daily basis. Our day-to-day work may include analysis of the following:


The Chemical Analysis Section uses a wide variety of instruments to provide environmental chemistry data:

  • Gas chromatography.
  • Gas chromatography/mass spectrometry.
  • High pressure liquid chromatography.
  • Ion chromatography.
  • Inductively coupled plasma/mass spectrometry.
  • Inductively coupled plasma/optical emission spectroscopy.
  • Total organic carbon.
  • Lachat.
  • Digiblock digestors.
  • Turbovap concentrator.
  • Heated/pressurized Soxhlet extractor.
  • Toxicity characteristic leaching procedure extractors.
  • Millipore water filtration units.
  • Infrared dryer.
  • Turbidity system.
  • Muffle furnace.

High Quality Analytical Results

The Chemical Analysis Section provides analysis of soil, water, sludge and air samples to help protect Missouri's residents and natural resources. Through analysis, staff identify and confirm the presence of natural and man-made pollutants.  These pollutants may consist of volatile organic compounds such as petroleum products, biological contaminants found in wastewater discharges, heavy metals including lead and mercury or synthetic organic compounds consisting of pesticides and polychlorinated biphenyls, or PCBs.
