Exercise: Environmental Monitoring Scenario

Scenario: A local water treatment plant is experiencing an increase in complaints about an unpleasant odor in the drinking water. The plant suspects a volatile organic compound (VOC) contamination.

Task: Using the Voyager GC system, outline a plan to identify the suspected VOC and determine its source within the water treatment plant.

Include:

  • Sample collection points (e.g., raw water intake, treated water, specific filtration stages).
  • Analysis parameters (e.g., target VOCs, expected concentration range).
  • Potential sources of contamination within the plant (e.g., leaks, spills, chemical storage).
  • How the results from the Voyager GC will be used to identify the source of the contamination.

Exercice Correction

Here's a possible plan for identifying the VOC contaminant:

Sample Collection Points:

  • Raw Water Intake: To assess if the contamination is present in the incoming water.
  • Treated Water: To confirm if the contamination persists after the treatment process.
  • Specific Filtration Stages: To pinpoint the stage where the contamination is introduced or removed. For example, sampling after pre-treatment, after filtration, and after disinfection.

Analysis Parameters:

  • Target VOCs: The analysis should target VOCs known to have a strong odor, including common industrial solvents, chlorinated hydrocarbons, and aromatic compounds.
  • Expected Concentration Range: Based on the severity of the odor, the analysis should consider a range from trace levels to potentially higher concentrations.

Potential Sources of Contamination:

  • Leaks or Spills: Inspecting equipment, pipes, valves, and storage tanks for leaks or spills of potentially contaminated substances.
  • Chemical Storage: Evaluate the storage of chemicals used in the treatment process for potential leaks or improper storage conditions.
  • External Sources: Consider the possibility of contamination from nearby industrial facilities or agricultural runoff.

Using the Voyager GC Results:

  • Identify the Contaminating VOC: The Voyager GC will provide a clear identification of the specific VOC present in the samples.
  • Determine the Source: By comparing the presence of the VOC in different sampling points, the location of the contamination source within the plant can be narrowed down.
  • Confirm the Source: Further investigation and testing of the identified source will be necessary to confirm its role in the contamination.

Example: If the VOC is detected at the raw water intake but not in the treated water, it suggests the contamination is coming from the source water. However, if the VOC is present in the treated water and higher concentrations are found after specific filtration stages, it points to a potential problem within the treatment process itself.
