What is water pollution?

Providing sustainable water services for Brisbane requires smarter thinking and innovative solutions.

Industry is only one source of water pollution. Other sources include sewage treatment plants, households, streets and footpaths.

Individuals pollute water by littering (including cigarette butts), pouring oils down the sink, and using fertilisers and other chemicals on their gardens. These pollutants are then washed or blown into stormwater drains and local waterways.

What are the major water pollutants?

The use of sprayers to distribute municipal wastewater in swamp systems should be discontinued until the cause of tree mortality is established. Death of trees represents a major impact on swamp structure, productivity, and elemental cycling processes. It is probably also indicative of large and unacceptable changes to the soil, including soil microbes and fauna.

Research throughout the world is establishing design and performance criteria for the removal of BOD, suspended solids, nitrification and denitrification, phosphorous removal and disinfection via wetlands.

Reclaimed wastewater is the effluents of a sewage treatment plant (STP) that are adequately and reliably treated with different wastewater treatment process and is an important supplemental water resource for urban use, food crop irrigation, and recreational impoundments in many countries, especially for drought areas [1,2]. Besides the sensory problems related to odor, color, and turbidity, the occurrence of endocrine-disrupting chemicals (EDCs) in the reclaimed water is of concern when the water is used for agricultural irrigation, landscape irrigation, and groundwater recharge.

Salmonella bacteria continue to be an important public-health problem and have a serious economic impact on the U.S. poultry industry. Although the majority of human infections traceable to Salmonella enteritidis are related to egg consumption, this serotype has also been isolated from a variety of nonegg food items such as meat, vegetables and fish. In Southern California, S. enteritidis phage type 4 infection is the predominant serotype found in human patients. However, the organism has also been found in municipal sewage effluent and in rodent and poultry environments.

Disinfection of Sewage Effluents: The Jersey Experience

Changes observed in gene expression and hormone production suggest the presence in Hong Kong coastal waters of pollutants with endocrine disruption potential and others of significant toxic effects.

Floodwaters pick up sewage and chemicals from roads, farms and factories. If your home has been flooded, protect your family's health by cleaning up your house right away. Throw out foods and medicines that may have met floodwater.

However, muddy water compromises the aesthetic values of the water. Further, large amounts of sediments in the water can also impact on aquatic life by clogging the gills and smothering stony habitat. Finally, high frequency of high turbidity is the sign of accelerated land erosion.
