Project Profile 2 – Wastewater Treatment Facilities

A large Canadian municipality wished to perform an air quality study on several new wastewater treatment facilities. The desired focus of this study was to assess and quantify known industry hazards, identify the specific causes of employee air quality concerns, and to determine methods for exposure reduction.
This project was complex and important and involved multiple Stakeholders. From company Management and Workers, to JOHS Committee and Union Representatives, there were a number of interested parties involved. Because of our thorough and specific approach, including our unique method of interacting with and involving multiple Stakeholders, we were the Consultant chosen to assist the Municipality in achieving its desired outcomes.
We performed a detailed and thorough assessment of multiple facilities, including:

  • Meeting with management to discuss the implementation strategy and ensure that the specifics of our proposed approach were in alignment with those of the organization.
  • Interviews with facility employees to review the study objectives and proposed approach, determine priority areas for assessment, and obtain feedback on perceived air quality issues.
  • Inspections of the worksite, review of work procedures, assessment of the processes and equipment, review of material safety data sheets for all chemical products handled within the facility, and assessment of the hazards associated with process wastes.
  • Assembly of a detailed sampling plan that included testing for a number of known industry hazards, and some lesser known but important microbial hazards.
  • Comprehensive air sampling conducted according to the approved sampling plan.
  • Provision of a detailed report outlining sampling and assessment results, recommendations for exposure reduction and recommendations pertaining to process and work practice improvements.
  • Meeting with Management to review the air quality assessment report and strategize on the included recommendations.
  • Meetings with facility employees to review the results of the air quality assessment and discuss Management’s proposed action plan.
  • Provision of support for the implementation of report recommendations.

A number of opportunities to reduce employee exposures to airborne contaminants were identified, as well as several process and equipment issues. As a result, the Client was able to improve the air quality within their facilities and reduce employee occupational exposure to harmful airborne contaminants.
Additionally, the Client was able to pursue correction of several identified equipment and facility issues while they were still within the warranty period. Positive feedback on the air quality assessment process and results was received from all Stakeholders.
