Specialized Services

The Environmental Microbiology Laboratory specializes in the following areas:

  • Field Sampling (air, soil, waste water, recreational water, swabs,
    bulk, tape lifts)
  • Microbiological Indoor Air Quality Assessments (including building investigations, occupant surveys, sampling, consultancy)
  • Sewage Contamination Assessments (detection of bacteria associated with the presence of sewage)
  • Testing of water soluble chemicals to determine percentage biodegradability
  • Analysis of waste water for the Five-day Biochemical Oxygen demand test and Coliforms
  • Analysis of recreational waters (fresh and marine) for Public Health indicator organisms (e.g. Coliform group of bacteria – Total, Faecal, E.coli and Enterococcus sp.)
