Water Quality Monitoring

Human actions related to growth, urbanization, and industrialization are placing tremendous stress on water resources. Compounding this stress are risks related to climate change and global water scarcity, which further threaten the long-term stability of water supplies.

As an important measure to help protect waterways and aquatic ecosystems, water quality and water level monitoring can provide data and valuable insights that help scientists and water managers better understand the conditions of water resources and how those conditions change and are affected by development, agriculture, and other activities. Information such as water temperature, water level, dissolved oxygen, conductivity, salinity, pH, and turbidity can be invaluable in helping governments and municipalities control water pollution and make more informed water management and conservation decisions.

Onset provides research-grade data loggers for capturing accurate water quality and water level data. Simple to use, reliable, and easy to deploy, Onset’s data loggers are capable of operating in harsh conditions and a wide range of temperature extremes.
