Study Notes

Water Quality Overview

Defined by physical, chemical, biological, and aesthetic characteristics (appearance and smell).
Essential for sustaining diverse communities of organisms and protecting public health.

Importance of Water Quality

Impacts community water use: drinking, swimming, commercial activities.
Crucial for:
- Supplying drinking water
- Recreational activities (swimming, boating)
- Irrigating crops and livestock
- Industrial processes
- Navigation and shipping
- Aquatic food production (fish, shellfish)
- Protecting aquatic ecosystems and wildlife habitats
- Scientific research and education

Consequences of Poor Water Quality

Degraded water resources lead to loss of environmental, social, and economic value.
Threatens public health, ecosystem habitats, agriculture, fishing, and tourism.

Factors Affecting Water Quality

Tightly linked to surrounding environmental conditions and land use.
Monitoring focused on local contaminants due to high assessment costs.
Data aids in developing management programs to protect water quality.

Water Quality and Aquatic Ecosystems

Aquatic ecosystems include diverse organisms interacting with their environment.
Maintaining these ecosystems is essential for:
- Supporting human populations and environmental health.
- Fostering genetic diversity and ecosystem stability.
- Indicating overall water quality and suitability for various uses.
- Providing significant protein sources for humans and supporting commercial/sport fishing.

Water Quality Management

Key tools for managers include monitoring and protecting public health, economic support, and ecosystem maintenance.
Vital for river health, impacting native fish, vegetation, wetlands, and birdlife.
Necessary for diverse human activities: irrigation, livestock, recreation, and cultural needs.

Water Quality Objectives

Established through community consultation to protect environmental values and water uses.
Includes recreational use, healthy aquatic ecosystems, and safe drinking water.
Implemented for both surface waters and marine environments.

Definition of Water Quality

Essential to human life and environmental health, covering various types: marine, estuarine, freshwater, and groundwater.
Interdependent dimensions: quantity and quality.
