What is the hardness level of Malaysia water source? According to Wikipedia, water is classify as soft water when the hardness is below 60 mg/L, below 60 ppm or below 3.5gpg ( grain per gallon) . ( Hard/ Soft Calssification Table, Source: Wikipedia - Hard Water ) * Parts per million (ppm) is usually defined as 1 mg/L CaCO3. It is equivalent to mg/L One recently study on Kuala Lumpur Tap Water in 2007 has shown that most populated areas in Kuala Lumpur are soft water. (source: A Survey Of Tap Water Quality in Kuala Lumpur - March 2007 ) Also commentary of the study has confirmed that piece of finding. "As shown in figure 3, the hardness of tap water in these20 selected areas ranged from 48 mg CaCO3/L to 92 mgCaCO3/L with an average of 65 mg CaCO3/L. The tapwater in all these areas is considered soft as the hardnesslevel is below 100 mg CaCO3/L. Although there is nohealth-based guideline value, soft water and low pH maycause corrosion of pipes result
