Water Quality Technicians perform laboratory and field-based water testing to assess chemical, physical, and biological parameters across drinking water, surface water, groundwater, and wastewater systems. They collect samples, operate analytical instruments, document results, and support regulatory compliance. Their work is central to protecting public health, monitoring environmental impacts, and ensuring adherence to water-quality frameworks. As climate change affects water availability and quality, global demand for water technicians continues to grow across utilities, laboratories, environmental agencies, and consulting sectors.
