Werribee River: Water Quality Analysis Report

Introduction

Water Quality Analysis Report x300The river system is important for human life and the functioning of society where it provides a number of goods and services including clean water for drinking and washing, water for agricultural and industrial purposes, benefits for the community by enhancing liveability and providing public open space, buffers against flooding and the capacity to support and maintain fisheries and other food sources. Once these rivers become unhealthy, they lose their ability to provide their true value.

River health

A healthy river (river health) is one that can support and maintain key ecological processes. It depends on its ability to (Bond et al., 2012):

  • Maintain its structure and function
  • Recover from disturbance
  • Support local biota, human communities,
  • Maintain key processes such as sediment transport, nutrient cycling, assimilation of waste products and energy exchange.

Water quality

Water quality is a key attribute of aquatic ecosystems and is an important part of any river health assessment, responding to both natural processes and human disturbance. Physical, chemical and biological factors can be used to determine water quality. Physical properties include recording temperature and turbidity; chemical characteristics incorporate collecting pH, dissolved oxygen levels, nitrogen and phosphorus, whilst biological indicators comprise of sampling for algae, phytoplankton and aquatic invertebrates
