Pollution of Water Sources in Malaysia

Introduction In Malaysia, rivers are used as a source of water and various development needs. We can not deny that water is a very important natural resource. Demand for irrigation, industrial and household consumption consumes water, but other development such as recreation, hydroelectric power generation, transportation depends on water quality and availability (Talib, Ariffin, & Baharom, n.d.). However, humans do not seem to recognize how important it is. Taking away from them the ability to fulfill their quality and important functions brings significant consequences, brings long-term economic losses, and affects the quality of life throughout the population.

Malaysia's water pollution comes from point sources and non-point sources. Specified point sources include sewage treatment plants, manufacturing, agriculture and animal farms. Non-point sources are mainly diffusion sources such as agricultural activities and surface runoff. According to the 2004 Malaysia Environmental Quality Report 2004, the Ministry of the Environment made 17,991 in 2004 mainly including sewage treatment plants (54%), manufacturing (38%), animal farm (5%) and agricultural industry (3%) The source of water pollution was recorded. ) Another major cause of global water pollution is oil spill. New research by the National Research Council shows that approximately 29 million gallons of oil enter the seas outside North America every year.

Water pollution is usually caused by human activity. Various human resources increase water pollution. There are two sources. Point source and non-point source. Point sources release pollutants at specific locations to surface water through pipes and sewers. An astigmatic source is a source that can not be traced back to a single discharge point. Water contamination was detected in the laboratory, where small amounts of water were analyzed and various pollutants were obtained. Creatures such as fish can also be used to detect water pollution. Their behavior and changes in growth indicate that the water they live in is contaminated. Certain characteristics of these organisms can provide information about the type of contamination in their environment. The laboratory also uses a computer model to determine the dangers that may be present in a particular area. They import the underwater data into the computer, and the computer determines whether the water contains impurities.
