WATER is a basic requirement of living things. When humans, animals, plants and water shortages, it will die. Anyway, very extensive water damage to life, especially for food and drinking water. People will be dehydration or disease if the lack of fluid in the body.
Trouble is, the current drinking water quality in major cities in Indonesia are still apprehensive. Population density, spatial structure is wrong and the high exploitation of water resources is very influential on the quality of water.
Two experts expressed the opinion that water and wastewater Arie Herlambang and Nusa Idaman Said of the Centre for Environmental Technology Application Pengajian and friend to the media recently.
Nusa Idaman Said explained the government had issued a subsystem No 907/Menkes/SK/VII/2002 to the Terms and Drinking Water Quality Monitoring.
Terms of drinking water''in accordance Permenkes should be free of inorganic materials and organic. In other words the quality of drinking water must be free of bacteria, chemicals, toxic, hazardous and so forth,''said Arie.
Drinking water quality parameters that relate directly to health in accordance Permenkes is related to microbiology, such as E. coli and coliform. Associated with organic chemicals such as arsenic, Flouride, chromium, cadmium, nitrite, cyanide and selenium.
While the parameters are not directly related to health, among others, in the form of odor, color, total dissolved solids (TDS), turbidity, taste, and temperature. For chemical parameters such as aluminum, iron, chloride, manganese, pH, zinc, sulfate, copper, residual chlorine and ammonia.
Water pollution in the region major cities in Indonesia, continued Arie, very big. Based on statistical data of BPS (Statistics Indonesia) DKI Jakarta in 1998 approximately 50% of households using tap water (taps), soil water using pumps at 42.67%, dig wells and the other 3.16% 0.63%.
''The problems start to appear on the product quality of drinking water. The water quality of rivers and ground water is less qualified. Many people dispose of garbage, sewage and waste into the rivers. In fact, there are other ways to dispose of hazardous waste plant at a depth of several meters,''said Arie.
Furthermore, he explains the source of clean water in Jakarta came from the Citarum River (80%), Cisadane (15%) and the rest Ciliwung. Those rivers across various rural, residential, industrial, and transportation is quite solid. However, public awareness in protecting the environment is still low, so the river one of the natural resources vulnerable to contamination.
In rural areas the community was experiencing a crisis worthy of drinking water. Excessive use of pesticides contaminate the water in the paddy fields which then flows into the river and used the community to everyday life.
Not a few villagers were washed with detergent at the edge of time. Similarly, the coastal community was having trouble finding fresh water. Consequently, they use sea water with high salt content.
''In the meantime, water treatment technology used is still lagging taps. In the processing of raw water into potable water taps technology used only eliminates bacteria E. Coli and iron. While the content of a carcinogen was never done''.
