|Environmental monitoring encompasses a vast range of objectives and sampling strategies. Some examples are:
• Characterize waters and identify changes or trends in water quality over time.
• Identify existing or emerging water quality problems.
• Gather information to design pollution prevention or remediation programs.
• Determine whether goals, such as compliance with pollution regulations or implementation of effective pollution control actions, are being met.
• Respond to emergencies such as spills and floods.
Some types of monitoring activities meet several of these purposes at once while others are specifically designed for one reason.
For long term studies, CDOM, turbidity, pCO2, carbon sediments and nutrients are some of the primary hydrological parameters that are monitored providing environmental information essential for effective water resource management and research. Real-time data combined with historical information helps managers and researchers make empirically-based water resource and environmental decisions.
When implementing emergency response strategies, parameters such as crude and refined fuels as well as biological indicators such as coliform and optical brighteners are often the focus.
