Many have asked the difference between the different types of drinking water filters they could use in their homes, at work, or at school.

Activated Carbon Filter:

• Positively charged and highly absorbent carbon media in the filter attracts and traps many drinking water impurities.
• You will typically find these drinking water filter systems on countertops, as point-of-use faucet filters, and under the sink.
• A good system for eliminating bad tastes and odors and a well-rated activated carbon filter will filter out many hazardous contaminants such as heavy metals, disinfection byproducts (i.e. haloacetic acids and trihalomethanes to name a few), chlorine, radon, volatile organic chemicals, parasites, and pesticides.

Why Install a Reverse Osmosis Water Filter?

Many of our readers have asked questions about reverse osmosis drinking water filtration systems and want to know more about them. Hence the purpose and reason for this deviation from the normal subject matter in this Water Testing Blog entry.

“Today, people are increasingly concerned about the quality of the water that they consume. Under the best of conditions, it’s possible that water may contain hazardous contaminants, ranging from dissolved organic and inorganic materials, to suspended particles and microorganisms. If you live in a home with older pipes, you may also be exposed to lead in your water. Even the chemicals, like chlorine and fluoride, that many municipalities add to water to kill bacteria or to fight tooth decay may be harmful to humans. If such chemicals are not used, your water could be harboring deadly parasites. If you suspect your water may contain microorganisms, lead, or other contaminants, have your water tested.

To decrease their exposure to possible contaminants, many people drink and cook with bottled water or put distillers or disposable cartridge filters on their water supply lines and faucets. However, bottled water may not be any purer than the water taken from your faucet, distilled water requires boiling and tastes flat, and although charcoal filters improve the taste and remove odors from water, they do little to remove chemical contaminants and microorganisms. If you find your water is contaminated, choose the correct water filtration system to correct the problem.

Reverse osmosis (RO) is generally recognized as the best system for purifying water while retaining good taste. The EPA recommends reverse osmosis filters for microbiologically safe water. Yet, an RO system alone will still allow certain waterborne germs to pass through. To knock out these types of contaminates, most RO systems incorporate some additional type of filtering, usually a replaceable carbon post filter. ( source )”

If You Can Visually Detect Problems With Well Water…

• Scale or ’scum line’ from too many from calcium or magnesium salts in water. total hardness test kit
• Unclear, murky or turbid water caused by suspended solids such as dirt, clay salts, silt or rust in water. tds test kit | tds meter
• Green stains forming on sinks or faucets as a result of high acidity. pH test kit
• Brown-red stains forming on sinks and fixtures, in the dishwasher, or on washed clothes may indicate the presence of dissolved iron in water. total iron test kit
• Initially cloudy water that clears up completely if allowed to sit undisturbed for a few minutes may have had fine/small air bubbles injected in it by a poorly working pump or because of a problem with filters.

If an Unusual or New Taste is Detected in Well Water…

• A salty or brackish taste in the water typically results from a high sodium content. chloride test kit
• Presence of an alkali/soapy taste may come from dissolved alkaline minerals in water.
• Acidity or a high iron content may result in a metallic taste. pH test kit | total iron test kit
• Chemical tastes are known to come from industrial chemicals or pesticides. pesticides test kit

If an Unusual or New Odor is Detected in Well Water…

• A rotten egg odor may be the result of dissolved hydrogen sulfide gas or certain types of bacteria in your water. Note, though, that if you only notice the smell coming from hot water, it is more than likely coming from a part in your hot water heater. hydrogen sulfide test kit
• You may notice a detergent odor and/or foaming water of seepage from septic tanks has gotten into your well.
• A gasoline or oil smell indicates (obviously) that some form of fuel oil or gasoline has found its way from a tank into the water supply.
• Decaying organic matter can result in a methane gas or musty/earthy smell coming from the water.
• Excessive chlorination of a well, or not waiting long enough after shocking a well with chlorine (obviously) results in a chlorine smell coming from the water. free chlorine test kit | total chlorine test kit

As always, if you suspect that your well has gotten contaminated in any way, always consult with a trained water professional. Do-it-yourself home water test kits like Well Water Check, COMPLETE Water Test Kit and the Drinking Water Test Kit serve as excellent screening tools but they do NOT have the same amount of accuracy as the results you can get from a certified water testing laboratory. It’s your well, your water, and ultimately — your life.

Many people fail to realize the impact that pesticides in water can have on wildlife, on aquatic life, and in what humans consider ‘extreme’ situations, on human life.

In an article by Jeff Barnard (Associated Press Writer) published on Yahoo News on Thursday August 14, 2008. . .

“GRANTS PASS, Ore. - Three pesticides commonly used on farms and orchards throughout the West are jeopardizing the survival of Pacific salmon, the federal agency in charge of saving the fish from extinction has found.

Under the settlement of a lawsuit brought by anti-pesticide groups and salmon fishermen, NOAA Fisheries has issued a draft biological opinion that found the way chlorpyrifos, diazinon and malathion get into salmon streams at levels high enough to kill salmon protected by the Endangered Species Act.

. . .

Banned from many household uses, tens of millions of pounds of the chemicals are still used throughout the range of Pacific salmon on a wide range of fruits, vegetables, forage crops, cotton, fence posts and livestock to control mosquitoes, flies, termites, boll weevils and other pests, according to NOAA Fisheries.

. . .

The chemicals are the first of 37 that NOAA Fisheries and EPA must evaluate by 2012 under terms of a settlement reached last week in a lawsuit brought by Northwest Coalition Against Pesticides and the Pacific Coast Federation of Fishermen’s Associations, which represents California commercial salmon fishermen.

A total of 28 species of Pacific salmon are classified as threatened or endangered from overfishing, dams, logging, grazing, urban development, pollution, irrigation, misguided hatchery practices and other threats.

Lecky said he could not say where pesticides rank in the threats to salmon, but eliminating the harm from pesticides would boost efforts to save them.”

This naturally leads all of us here at Water Testing Blog to wonder what sort of effect those same compounds may have on human life.

With that in mind, we sought out testing methods for ‘common’ pesticides currently viewed as harmful and/or toxic to human life and sometimes found in well, surface, and drinking water. We discovered the Pesticides in Water test kit which detects Atrazine and Simazine in drinking water at levels established by the United States Environmental Protection Agency as harmful to humans.

The Pesticides in Water test kit detects Simazine at the Maximum Contaminant Level (MCL) of 4 parts per billion and Atrazine at the Maximum Contaminant Level (MCL) of 3 parts per billion.

As always, though, if you have serious reason to suspect the accidental or intentional addition of harmful chemicals to your drinking water supply, we suggest you seek the testing services of trained water professionals.
