RESEARCHERS HAVE SHOWN THAT THERE IS DANGER OF HEART ATTACK DUE TO THE USE OF SOFT WATER.

Researches have shown that there is a greater occurrence of the heart attacks in populations using soft water than those relying on hard water from wells, reservoirs and the rivers. Soft water, which is low in calcium and magnesium salts, tends to be more acidic than hard water. Distilled water, for example is 100 percent soft. Why such differences should be important to man's health is what baffles scientists, they offer, however, two possible explanations as described below:-- (1) Hard water could contain a factor that helps prevent attacks. This factor might be missing in soft water. (2) Soft and acidic water could leach cadmium and lead from water pipes and become harmful. Soft waters have corrosive action on a number of metals;dissolve lead from lead pipes and cisterns and become dangerous to the health. Soft water is flat and is tasteless where as a moderately hard water is more palatable and often a good drinking water. Soft water can be improved in taste by the addition of a little common salt or by oxidation. If water is allowed to fall over a series of weirs, or poured from one vessel to another several times allowing it to fall some distance through the air, this will improve its quality for the purpose of drinking and also help to purify it. Soft water feels smooth to the touch and readily forms a lather with soap, while hard water is rough to the skin and curdles a certain amount of soap before a lather is formed. The common practice to measure the hardness in terms of parts per million by weight-- in terms of calcium carbonate not exceeding 70 ppm. Is termed soft and above that it is termed hard. In public water supplies, it is customary to reduce carbonate hardness to 35 to 40 ppm and total hardness to between 50 to 100 ppm. A much softer water is needed to boiler
