How to Remove Harmful Pesticides From Your Home Drinking Water  

In my last article, you learned that pesticides in your water can be harmful. Here you will learn how pesticides can be removed from your home drinking water.

Granular Carbon 

Granular carbon is one of the most effective compounds to remove chemicals from air and water. However, there are some disadvantages. It is possible for water to channel around the granules. If the water does not pass over the surface of the carbon, chemicals will not be removed.  

Granular carbon works through a process called adsorption. Chemicals literally stick to the surface of the carbon, but the chemicals must pass over the surface of the carbon in order for it to work. It is because of this fact that some carbon purifiers are more effective than others. 

Another problem with the carbon granules is that they can pass along with the water, leaving a black residue in your glass. One of the older purifiers was removed from the market because of that problem. The manufacturer did not understand how to correct it. Luckily, some manufacturers understand that the solution is a second phase that includes a solid carbon block. 

• A Solid Carbon Block 

By boring a submicron sized channel into a solid block of carbon and forcing the water to pass through the channel, any chemicals not removed by the granular carbon will stick to the edges of the channel. The channel also ensures that no black residue gets through the faucet. 

Another advantage of the sub-micron sized channel is that it will filter out any cysts that might be present. Cysts are tiny egg-like structures that are actually the early developmental stages of some kind of parasite, usually cryptosporidium.  

The EPA has warned that cysts may be present in any public supply at any time. The illness caused by cysts can kill an at-risk individual. Those who are at-risk include infants, children, the elderly, people recovering from chemo-therapy and those with weakened immune systems. 

• What is the Effectiveness of The Two Stage Purifiers? 

For removal of pesticides such as lindane, the effectiveness is close to 100%. Not all manufacturers include both stages. So, it is important to do some comparative shopping before you buy. Otherwise, you could think you were being protected, when you actually had no protection. Here are a few other things to consider. 

• Other Contaminants 

In addition to cysts, there are other hazardous contaminants known to be present in publicly treated supplies. Most of them are THMs or trihalomethanes. Exposure to THMs has been proven conclusively to increase a person’s lifetime risk of cancer. Additional filtering media is necessary to remove THMs. 

• Filter Lifespan 

In order to have continuous protection, the carbon filters need to be replaced on a regular basis. The manufacturer should be able to advise you about how often to replace your filters. Believe it not, some manufactures will not make a recommendation. They say it depends on the amount of water you use. 

While that is true, there is an average amount used by most households for drinking. The average allows manufacturers to estimate the lifespan of a filter. Be sure to replace them according to the estimate. Otherwise, your protection is lost.   How to Remove Chlorine From Home Water Safely
