Environmental Chemistry Division
The Public Health Laboratory's Environmental Chemistry Division analyzes samples from Mississippi's public water supplies for regulatory compliance. It employs a Division Director and nine analysts.

The Division is equipped with inductively coupled plasma-mass spectrometers, a cold-vapor mercury analyzer, a high-performance liquid chromatograph, an ion chromatograph, flow-injection analyzers, an auto-titration analyzer, gas chromatographs, and purge-and-trap gas chromatograph-mass spectrometers, as well as the preparation equipment to support these instruments.

Laboratory Certification Program

The Environmental Chemistry Division also operates and maintains the chemistry section of the Water Supply Laboratory Certification Program, which certifies laboratories for drinking water compliance monitoring within the state of Mississippi.

 

Further information on lab certification can be found on the Laboratory Certification page.


Analysis

Drinking Water Analysis
The Environmental Chemistry Division analyzes drinking water for a number of chemical contaminants:

  • Metals
  • Inorganics
  • Inorganic Disinfection By-Products
  • Insecticides
  • Herbicides
  • Carbamates and Vydate
  • Polychlorinated Biphenyls
  • Semivolatile Organic Compounds
  • Volatile Organic Compounds
  • Trihalomethanes
  • Haloacetic Acids

Results for these tests are forwarded to the MSDH Bureau of Public Water Supply to ensure regulatory compliance. The Division of Water Supply is the enforcement authority responsible for ensuring that public water systems comply with the Safe Drinking Water Act.

If residents have questions concerning the quality of drinking water from their public water system, they should contact the MSDH Bureau of Public Water Supply's Compliance and Enforcement office at (601) 576-7518.
