Water Quality Monitoring

A practical hub for understanding water quality parameters, selecting monitoring methods, and planning field sampling programs for stormwater, wastewater, surface water, reuse, and facility compliance.

Start with the monitoring objective

Water quality monitoring should begin with the question being answered. Compliance sampling, field screening, treatment verification, and long-term watershed monitoring can require different parameters, sampling frequency, equipment, documentation, and quality control.
