10/4/2016 1:07:24 PM | Part 2 Water Quality: If you have read the linked article in the first post then you have just an inkling of the degree of toxicity in our water supplies! Perhaps you have requested a copy of the latest lab tests from your public water supplier. You may have noticed that Heavy Metals were not mentioned in the first post, that is because most water supplies will contain them at some level and so how we choose to treat our water must include a way to remove them. Today we will begin looking at how to clean up the water we drink, cook with and bath in. We will refer to Whole House (WH) systems and Point of Use (POU) systems. If you own your own home than treating the water where it enters your house with a WH system is the first step. If you read the first post there a WH system is mentioned near the end of the article. In my experience this can be accomplished for a lower expenditure if you are willing to spend some time looking for a small independent water treatment company that sells water softeners. They can supply you with and install a large tank filled with granular activated carbon (GAC) with a back wash system (very important to break up the water channels that will form in the tank). A less expensive way and one I have used is to purchase the large water filter housings, either #20 (20 inches long) or Big Blue housings with carbon cartridges inside. If you can plumb, they are relatively easy to install or pay a handy-man/woman. They will need regular changing out of the cartridges depending on sediment and chlorine levels, so be sure to install a shut off valve before and after for ease in changing the filters. You can install two of these filter housings in a row and when it is time to change out the cartridges you can save by discarding the first cartridge, moving the second to the first housing and installing the new filter in position two. Now all the water at all outlets will have greatly reduced chlorine and chlorine by-products! For those who can not afford to do this and those who rent, we will be using POU systems. Lets start with bathing where we get our largest exposure to chlorine and chlorine by-products through the skin and breathing vapors. We will address showering only, because treating bath water as it rushes out of the spigot is difficult to say the least. A shower filter is the way to go. There are many in the marketplace so you can look around. I have been satisfied with the Aquasana Shower Filter System because of ease of installation and cartridge changes. Look for sales and signing up for regular filter changes can save money too. Now for drinking and cooking water. There are several ways to approach this depending on the quality of water desired and costs. We will be speaking only of counter-top systems (POU) as opposed to more permanent under-counter systems as they have several problems not the least of which is contamination of the storage tank, water quality issues, more difficult maintenance and higher costs. Counter-top systems are easily connected to the sink faucet with a diverter valve. If you are already using your tap water for drinking and cooking the simplest and least expensive system would be a single housing with water spigot and a carbon block filter. This will greatly reduce chlorine, chlorine by-products and improve taste and odor, however it will do little to remove heavy metals (lead, arsenic, cadmium etc.) or fluoride. To address those you would need to spend more for a filter cartridge that contained some form of media specific to capturing heavy metals. My choice however would be to add a second filter housing with a filter cartridge dedicated to removing metals and fluoride just before the carbon block. You can find these types of systems on-line, multi-level marketing and in stores like Walmart, Home Depot, Lowe's, etc. Once again Aquasana offers some solutions with their counter-top systems. To achieve higher levels of purity in your drinking/cooking water you can use either a distiller or reverse osmosis system, each has their pros and cons. Distillers equipped with both pre and post carbon filters produce an extremely pure water devoid of minerals. It is sometimes suggested that you add some minerals back in by using a concentrated product like trace minerals. The distiller should be made that all water comes in contact with only glass or stainless steel and should be stored only in glass because of its aggressive nature which will leach out plastic containers. They take up lots of counter space, are slow in producing water, use a good amount of energy to boil water, produce heat and are expensive. I would never recommend buying distilled water in plastic! Counter-top reverse osmosis systems offer a less expensive way to produce water very close to the purity of distilled water, so close that they usually qualify as distilled water by measurement of 10 ppm (parts per million) or less. I do not suggest under counter systems with storage tanks because of contamination, quality of water issues, additional plumbing and expense. Like distillers they are slow to produce water, waste water as it takes 4-5 gallons of water to produce 1 gallon of pure water and take up counter space and when running you cannot use the faucet for anything else. Still this is my favorite method for producing high quality water at home and there are work around's to all these issues except for water wastage. Finally, for those who cannot use any of these options and must buy bottled water, I strongly suggest that you avoid all water bottled in plastic and put some effort into finding a quality bottled water packaged in glass. Most bottled water is just city tap water that they treat with one or more methods, bottle it and sell it to you at extreme markups and in plastic! If you can find a company that bottles a true spring water whose source is protected by hundreds or thousands of acres of undisturbed land, in other words a well protected watershed, treats it with some form of sterilization like ultraviolet light and bottles it in glass, I would definitely consider that source for my drinking water and to save on use you could also install a inexpensive counter-top carbon block filter to produce your water for cooking. That's all for now folks. Hope this was helpful and not too confusing. Perhaps if there is a conference call on this topic we can try to answer further questions. Peace, love and joy to us all, Craig |
