Toxic organic chemicals The most pressing and widespread water contamination problem is a result of an organic chemicals created by industry. Chemicals end up in our drinking water from hundreds of different sources. There are hundreds of publications each year highlighting this problem. The effects of chronic long term exposure to these toxic organics, even in minute amounts, are extremely difficult to detect. Contaminated drinking water may look and taste perfectly normal. The users symptoms might include recurring headache, rash, or fatigue all of which are hard to diagnose as being water related. The more serious consequences of drinking tainted water are higher cancer rates, birth defects, growth abnormalities, infertility, and nerve and organ damage. Some of these disorders may go unnoticed for debates!
Chlorine Trihalomethanes (THM's) are formed when chlorine is used to disinfect water supplies, interacts with natural organic materials (e.g. By-products of decayed vegetation, algae, etc). This creates toxic organic chemicals such as chloroform, and Bromodichloromethane.
Colombia University found that women who drank chlorinated water ran a 44% greater risk by dying of cancer of the gastrointestinal or urinary track than did women who drank non-chlorinated water. Chlorinated water has also been linked to high blood pressure and anemia. Anemia is caused by the deleterious effect of chlorine on red blood cells.
