DataStream Launches New Interactive Guide to Water Quality

A new online tool helps explain how water quality is measured and why it matters.

The illustrated guide provides an introduction to some of the most important and commonly monitored aspects of water quality, including:

  • physical properties, such as water clarity, pH and temperature
  • chemical substances, like nutrients, metals, minerals and pollutants from human activity, and;
  • biological characteristics, including coliform bacteria and chlorophyll

Taken together these types of measurements can give us an indication of how healthy the water is and, importantly, how it may be changing over time.

Alongside local, place-based, and Traditional/Indigenous knowledge, this information can support decision-making and action to help protect our waters, so they remain healthy for generations to come.
