Water Quality Surveys

Water quality is one of our core areas of expertise. Our environmental consultants regularly perform routine and investigative water quality assessments. We have extensive knowledge and experience in compliance monitoring for construction sites, industrial facilities, roads and wastewater treatment plants.

We have particular expertise in relation to water quality management on wind farm construction sites including sites discharging into freshwater pearl mussel catchments, and also wastewater discharge licensing for waste water treatment plants. We take an integrated approach to water quality assessments, combining chemical, biological and toxicological assessments.

Water quality services we provide include river, lake, canal, estuary and inshore marine water quality determinations, consent to discharge applications, and surface water discharge analysis. We are experts in the use of biological indicators to assess water quality, and undertake aquatic ecological, microbiological and ecotoxicological assessments as part of our integrated approach.
