ABSTRACT
This paper deals with the water quality analysis report for the location 4 - Mars Creek in
Macquarie University situated at Balaclava Rd, Macquarie Park NSW 2109, Australia. In this
report we will find the relationship between the contaminants and the water present in the
Mars Creek. Water quality assessment at the mars creek watershed scale requires not only an
investigation of water pollution and the recognition of main pollution factors, but also the
identification of polluted risky reason resulted in polluted surrounding river sections. To
realize this objective, we collected water samplings from various sites in mars creek with
Grid GIS method to analyze six parameters including dissolved oxygen (DO), ammonia
nitrogen (NH3-N), nitrate nitrogen (NO3-N), nitrite nitrogen (NO2-N), total nitrogen (TN) and
total phosphorus (TP). Single factor pollution index and comprehensive pollution index were
adopted to explore main water pollutants and evaluate water quality pollution level. Based on
two evaluate methods, Geo-statistical analysis and Geographical Information System (GIS)
were used to visualize the spatial pollution characteristics and identifying potential polluted
risky regions. The results indicated that the general water quality in the watershed has been
exposed to various pollutants, in which TP, NO2-N and TN were the main pollutants and
seriously exceeded the standard of Category III.
INTRODUCTION
With the rapid growth in economic and social development in the country, non-point source
pollution to the environment from livestock and poultry industry, aquaculture industry,
planting industry, and rural domestic sewage to our living space centered on the Earth has
drawn much attention to the public and policy-makers (Niemi et al., 1990). This document
updates the Australian water quality guidelines for fresh and marine waters released in 1992
(ANZECC 1992).Specifically, this document outlines the important principles, objectives and
philosophical basis of underpinning the development and application of the guidelines, the
management framework recommended for applying the water quality guidelines to the
natural and semi-natural marine and fresh water resources in Australia and New Zealand,
provides a summary of the water quality guidelines proposed to protect and manage the
environmental values supported by the water resources; provides advice on designing and

implementing water quality monitoring and assessment programs has also been revised using
data, relevant literature, and other available information to at least 1996
(https://www.ijltet.org/journal/151736924028.%202064.pdf, 2018).
BACKGROUND
The current guidelines including this working documentation is taken from a revision of the
NWQMS guidelines published in 1992 (ANZECC 1992). The revision was necessary to
incorporate current scientific, national and international information in a clear and
understandable format, ensuring that the guidelines complement major policy initiatives and
directions undertaken at the state and federal levels in the areas of ecologically sustainable
development and water resource management, promote a more realistic approach to aquatic
ecosystem management, incorporate more detailed guidance on how to refine national or
regional guidelines for site-specific application, it is important input to the review process
from Australia and New Zealand has included public submissions on the 1992 Guidelines.
Earlier drafts of the revised document are the most recent local and overseas scientific and
resource management documents and information relevant overseas water quality guideline
documents and government submissions. In accordance with the script of philosophy of the
1992 Guidelines, the chapters in this document describe how to apply state-of-the-art
practices of water resource management and assessment for the protection of the
environmental values.
GUIDING PRINCIPLES
The Australian and New Zealand Guidelines for Fresh and Marine Water Quality are initially
based on the philosophy of ecologically sustainable development (ESD). The Australian
National Strategy for Ecologically Sustainable Development (ESD Steering Committee 1992)
defined ESD is defined as the development of ecological systems by conserving and
enhancing the community’s resources on the ecological processes on which life depends are
maintained along with the total quality of life aiming now and in the future that could be
increased (Yan et al., 2015). Illustrating more simply the ESD is a development process which
aims to meet the needs of Australians today, while conserving our ecosystems to the benefits
of future generations. The need to comply with ESD principles is being included in statutes

throughout Australia, with the commitment to continuous environmental improvement
through comprehensive and integrated public policy. The Purpose and Principles in the
Resource Management Act (1991) was to set out the philosophy and approach for water
management in Australia (Waterquality.gov.au, 2019). The purpose of the RMA is to promote
sustainable management, which is broadly equivalent to the ESD philosophy. The Guidelines
are also based on the policies and principles of the Australian National Water Quality
Management Strategy as explained in ANZECC and ARMCANZ (1994) (Yan et al., 2019). The
principles includes ecologically sustainable development, an integrated approach to water
quality management, including establishment of the environmental values and development
of management plans, community involvement in water resource management and
government endorsement of the water quality policy objectives (Meng, 2019). Four further
guiding principles have also been adopted by the Australian’s are: A coordinated and
cooperative approach to water quality management is vital and involves all spheres of the
community, government local and indigenous groups and the private sector. The high
variability and complexity inherent in natural water resources needs to be recognised and
taken into account when evaluating water quality or developing management strategies.
Water resources are special features of the environment and their quality and integrity should
be conserved and managed according to the intent of the Australian National Strategy for
Ecologically Sustainable Development, the Wetlands Policy of the Commonwealth
Government of Australia and the National Strategy for the Conservation of Australia’s
Biological Diversity (Waterquality.gov.au, 2019). Current research results shows the inter-
relationships between ecological processes, water quality and the biota and the dissemination
of these findings in a readily usable form which are essential for effective management of
water resources.
MATERIALS AND METHODOLOGIES
The Water Samples from Mars creek were collected from different sites in the morning hours
between 10 to 12 am in Polythene bottle regularly for every month. The Water samples were
immediately brought in to Laboratory for the Estimation of various Physico-chemical
parameters, like temperature of water and pH of water that were recorded at the time of
sample collection by using Thermometer and Pocket Digital pH Meter (Construction
Environmental Management Plan, 2019). Meanwhile other Parameters like DO, TDS, Free CO2,
