Water Matters

WaterWater matters

ASERIES of recent environmental incidents and disaster have highlighted the need for better-treated water quality, which is essential for the maintenance and upkeep of personal health and hygiene.

On April 4 2007, Health Ministry parliamentary-secre-tary Datuk Lee Kah Choon was

quoted by several local dailies stating that chlorine could be one of the factors that cause

miscarriage. He made the statement in response to Dr James Dawes Mamit's (BN- Mambong) contention that chlorine in our municipal piped water could cause miscarriages.

In early March 2006, high levels of ammonia content and bad odour were detected in

municipal piped water in the Klang Valley which was sourced from Sungai Selangor. According to Syarikat Bekalan Air Selangor Sdn Bhd (Syabas), operator of three water treatment plants along the river, it had increased the chlorine content in the contaminated raw water during the treatment process to reduce the ammonia content. The chemical reaction had resulted in the foul smell of piped water in several areas in Selangor and KL. In the same month, the Selangor DOE found that the ammonia level in Sungai Selangor had reached the danger level of 9.2me per litre compared to the safe level of 1.hmg per litre.

In view of the severity of such incidents, which may result in detrimental health consequences, consumersing additional measures necessary to improve the quality of

their municipal water supply.One simple and cost effective way to do that is to invest in an effective water filtration system that contains Granular Activated Carbon.

Water Filters and Granular Activated Carbon (GAC)

Activated carbon is one of the best tools, which can be used to reduce risks to human

health and provide an aesthetically pleasing water supply at reasonable cost.

Activated carbon has a natural affinity for organic pollutants like benzene and volatile organic chemicals (VOC), which bind to its surface, in a process call "Adsorption". If you "activate" carbon by steaming it at 1,800 degrees for example, it forms little pores and pockets that increase its surface area. honeycomb

Water filters containing Granular Activated Carbon (GAC) remove VOC, pesticides

and herbicides, trihalemethane compounds, radon, solvents and hundreds of other man-made chemicals found in tap water. These organics are of great concern in water treatment because they react with many disinfectants, espeeially chlorine, and cause the formation of disinfection-by-products (DBP). These DBP's are often carcinogenic (cancer causing) and therefore highly undesirable. The US Environmental Protection

Agency (EPA) estimates that VOCs are present in one-fifth They can enter ground water

from a variety of sources. Benzene, for example, may enter ground water or river from gasoline or oil spills on the ground surface.

Volatile organic compounds may have a variety of harmful health effects. At high levels of exposure, many YOCs can cause central nervous system depression (drowsiness, stupor). All can be irritating upon contact with the skin, or to the mucous

membranes if inhaled. Drinking water containing one or more VOCs at levels above standards should not be consumed. VOCs may also enter the body through skin absorption or through inhalation of water vapor. In any case, sources of VOC contami-nation should be eliminated if possible.

Besides pollutants like VOC and DBP, activated carbon is also extremely effective in

removing foul taste, smell, odor and color from the treated water supply.

Water filters with Granulated activated Carbon can be installed for point-of-use (POU)

treatment at the faucet or pointof-entry (POE.) treatment where water enters the home. POE or Whole House Water Filter Systems are recommended for VOC removal to ensure that all water used for drinking, cooking, cleaning, and bathing is free of contamination.
