Total Dissolved Solids in Water - Page 2
In addition, water supplies can contain dissolved organic chemical contaminants which are usually pollutants that enter water as a result of man's activities, such as insecticides, pesticides and herbicides. These are usually chronically, rather than acutely, toxic to man and other species in extremely small amounts. Trihalomethanes are dissolved organic contaminants, such as chloroform, which are formed in extremely small amounts by the reaction of chlorine used to disinfect water, with humic and fulvic acids from soil erosion. Other organics can enter both surface and groundwater through waste dumping, such as trichlorethylene, tetrachlorethylene (TCEs), polychlorinated biphenyls (PCBs), dioxin, etc. Many of the organic contaminants are probably groundwater (cancer-producing). The organics do not necessarily exist in water in the form of dissolved ions.
Why should you measure TDS levels in your water?
When TDS levels exceed 1,000 ppm (parts per million) it is deemed unfit for human consumption. A high level of TDS is an indicator of potential concerns and should be investigated before drinking. Even the best water purification systems on the market require monitoring for TDS to ensure the filters and/or membranes are effectively removing unwanted particles from your water.
The Secondary Drinking Water Regulations control contaminants in drinking water that primarily affect the aesthetic qualities of water. Several of these -- chloride, sulfate, copper, iron, manganese, zinc, and total dissolved solids -- are ionized contaminants.
Color and odor are contaminants that cause objectionable sensory responses to the water.
You can also use pH value to measure the acid or alkaline strength of a water supply and corrosivity refers to the ability of a water supply to disintegrate pipes and containers.
We are all affected by toxic chemicals in the air and food that we consume. Water is the only way to flush out these toxins so it is important to make sure your water source is providing pure water. This is especially important for children because they are much more sensitive to contaminants because their defense systems have not fully developed. The purer the water is the greater its ability to purify and cleanse the body, so drink up!
