As an example, ‘J. Mampilly’ from India installed a system and now seeks to determine if he has installed the correct unit. He asked,

I would like to know about how i can confirm the effectiveness of my water purifier. Labs in India that can certify and throw light on the camparative quality of water before and after using a water purifier. Thank You

Unfortunately we do not have familiarity with water testing laboratories in India and cannot directly assist with this situation. We can suggest, however, that you contact your local health department and ask them for a list of certified water testing laboratories in your area.

Before…

In order to know what type of filter or what filtering capabilities you should purchase, invest (yes, we said invest) in a thorough water analysis performed by a qualified water testing laboratory. Here, again, we suggest contacting your local board of health and asking them, for a list of certified drinking water testing labs. Alternatively, or if no labs exist in your immediate vicinity, you can use the services of accredited water testing companies such as National Testing Labs.

No matter what, though, always have your water tested BEFORE deciding on a water treatment system. Oh, and one more thing: Don’t think for one second that a salesperson doing an in-home water test has the same water testing tools or qualifications as a reputable water testing laboratory. Remember: 99% of all salespeople attempt to sell things and not accurately analyze a situation — especially if accurately diagnosing a situation could cost them a sale!

And after!

As ‘J. Mampilly’ has done, we should ALL take an interest in comparing the quality of water that comes out of our water filter systems. Only then will we know if the money we invested in (not spent on!) a quality drinking water filter system performs as expected.

Testing water quality beforehand gives us not only an idea of what we need to filter out of our water, but also a checklist of water quality parameters to monitor post-filtration. Should follow up water testing reveal that these ‘issues’ did not get corrected or suddenly show up months after the installation of a water system, perhaps the water filter has stopped working or never really worked properly in the first place and needs service of some sort.

And in conclusion…

Many people go through life ‘deaf, dumb and blind’ when it comes to the quality of their water — until an (initially) unexplainable health problem pops into their life. Then, and unfortunately sometimes too late, those same people get very interested in the quality of their water and want to punish or otherwise penalize others for allowing them to consume tainted, polluted and/or contaminated drinking water.

Although we feel much sympathy for the victims of poor quality drinking water, most of us here in the United States have the ability to at least once every great while perform basic testing for critical water quality parameters such as heavy metals (i.e. lead, mercury, copper, iron, etc.), coliform bacteria, pesticides (i.e. atrazine and simazine), chlorine levels (free and/or total), total hardness, total dissolved solids, and many others.

Many times the contaminants in a water supply will have no taste, carry no odor and not appear before the naked eye. Only testing will alert you to their presence.

Two questions we get on a regular basis:

    (1) “Do I Need a Water Filter?”
    (2) “How Do I Know if I Need a Water Filter?”

Quite frankly, we kinda’ wish someone would give us a penny for each time we’ve gotten that question in an email.. We’d have a ton of cash! But we digress.

As seemingly complicated and daunting as both those questions may seem, they both have the same answer: Only testing of your water, preferably by a certified water testing laboratory, will let you know if you need a water filter…

… And even then you will need to perform occasional water tests just to make sure the quality of your water has not changed since the last test (because it can!) and/or to make certain your water filter continues to function properly.

As with any matter that could possibly have detrimental effects on your health, though, you should always get a second opinion… or in this case read what the EPA says and plans to do regarding water quality in the United States:

The Environmental Protection Agency says most people don’t need to treat their drinking water at home to make it safe. But the agency adds that a home water-treatment unit can improve water’s taste, or provide an extra margin of safety for people “more vulnerable to the effects of waterborne illness” such as infants, the elderly or those with compromised immune systems. The EPA sets standards for about 90 contaminants that can end up in drinking water supplies—from micro-organisms to herbicides and discharge from industrial-chemical factories.

For each, the agency dictates a “maximum” amount allowed, and utilities are required to treat water and issue an annual report to customers about what’s detected. (If you’re drinking from a private well, you’re on your own.)

A home-treatment device may reduce such contaminants even further. Plus, the EPA sets drinking-water standards for just a fraction of the some 15,000 chemicals used in the U.S. In December, the not-for-profit Environmental Working Group released results of a three-year analysis of 20 million tap water quality tests performed by water utilities and found some 202 currently unregulated chemicals in water supplied across the country. That included rocket-fuel component perchlorate and MTBE, a gasoline additive. Other contaminants, such as copper and lead, may be introduced through corrosion of a homeowner’s own pipes or through leaching of brass or chrome-plated faucets and fixtures. There are DIY test kits starting at about $10 that can detect some contaminants, but a thorough analysis will require a professional to collect samples and send to a private lab.

“In almost every case, the utilities comply with federal standards but that doesn’t ensure that the water is safe to drink,” says Jane Houlihan, senior vice president for research for EWG. The EPA is evaluating the health effects of more than 100 contaminants currently unregulated in drinking water, including pharmaceuticals and disinfection byproducts, for possible regulation by 2013.

So… Do you need a water filter for your tap water or well water? Again, only testing will tell and since even the EPA suspects that it may have more drinking water contaminants to monitor, well, all of us here at Water Testing Blog know that WE will keep an eye on OUR drinking water quality and suggest you do the same, too.

Many people have the wrong idea about how much maintenance and testing a healthy aquarium requires. Notice we said, “healthy.”

An UNhealthy aquarium requires next to no maintenance. Simply add water to the tank, throw in some fish, wait for fish to die, scoop up dead fish, re-stock tank with live fish, and repeat the last two steps until common sense kicks in.

Eventually people catch on to the fact that an aquarium needs more attention than just adding fish and dumping in food once in a while. It takes some people longer than others to figure that out, true, but we can discuss that topic another time. For right now let’s stick to the topic at-hand: Testing Aquarium Water so that your fish don’t keep going belly up.

As you can see from the above test kits, you will have to test for a number different water parameters if you want to keep your fish healthy, happy and alive. Thankfully most aquarium test kits these days come with easy-to-follow instructions and the average person can complete the testing in just a few minutes.

Which water parameters matter most? Hard to say, but many pond and aquarium experts agree that a person ought to keep a close eye on the following water quality parameters if they hope to have clean, healthy water for their fish to live in:

• Ammonia Levels — As disgusting as it sounds to us, fish live in their own waste products, one of which is ammonia. Excessive amounts of ammonia result in respiratory problems for fish and if left untreated the fish will eventually stop breathing and die.
• Chlorine/Chloramines Levels — Extremely toxic to fish and pretty much all aquatic life even in small amounts. When adding fresh water to an aquarium, always make sure to test for and remove any and all traces of chlorine and chloramines.
• Nitrite Levels — When ammonia breaks down it forms nitrites, another very toxic compound which can cause respiratory distress in, and eventually the death of, fish.
• pH Levels — It ought to come as no surprise that fish don’t want to swim around in extremely acidic or basic water any more than you would want someone pouring hydrochloric acid or concentrated lye onto your skin. One thing to remember, though, about pH: Not all fish prefer the exact same pH so when choosing your fish, read up on their preferred water conditions — or risk killing some of your fish slowly and painfully.

The new test, which only takes about two minutes to complete, is reportedly able to identify perils associated with poorly treated water, though the chances of some reaching the ISS are extremely small. The new technique developed at the UU has just begun a six-month trial period aboard the ISS. “Now they bring water back on the space shuttle and analyze it on the ground. The problem is there is a big delay. You’d like to be able to maintain iodine or silver [disinfectant] levels in real time with an onboard monitor,” UU Professor of Chemistry and Chemical Engineering Marc Porter explains.

According to its developers, the new method is simple, effective and cheap. Water is sampled from the galley aboard the ISS, and then forced by a syringe to pass through a chemically imbued disk. The membrane modifies its color depending on the chemicals inside the water. The differences between the original hues and the new ones can be read with a commercially available color sensor, such as the one regularly used to assess the brightness and glossiness of car paint.

“Our focus was to develop a small, simple, low-cost testing system that uses a handheld device, doesn’t consume materials or generate waste, takes minimal astronaut time, is safe and works in microgravity,” Porter adds. Another bright side of the new technique is that it is currently being adapted for use back on Earth as well, where it could detect dangerous arsenic concentrations in drinking water. This type of tests could come in handy in places such as the US and Bangladesh, where the arsenic concentration is something to be reckoned with. ( source )

As the article stated, the odds of contaminated water ever reaching the space station in the first place are slim to none, but picture, if you will, a person floating around in near-zero gravity either throwing up all over the place or trying desperately to hold in explosive diarrhea… and you will quickly understand the importance of clean drinking water in space.

“WASHINGTON – Pick a tomato in the blazing sun and plunge it straight into cold water. If that happened on the way to market, it might be contaminated. Too big of a temperature difference can make a tomato literally suck water inside the fruit through the scar where its stem used to be. If salmonella happens to be lurking on the skin, that’s one way it can penetrate and, if the tomato isn’t eaten right away, have time to multiply.

That doesn’t mean people shouldn’t wash their tomatoes — they should, just probably not in cold water.

But as the Food and Drug Administration investigates the nation’s outbreak of salmonella from tomatoes, the example shows the farm isn’t the only place contamination can occur — and checking things like water quality and temperature control in packing houses and other supply stops is one key to safety.”

This raises the question of what sorts of water quality parameters packing houses should monitor on a regular basis.

Sanitizer and Disinfectant Levels — If the water used to wash, rinse and cleanse the tomatoes contains enough sanitizer, then theoretically no salmonella or other forms of bacterialogical contaminants could survive in the water. No contaminants in the water means no contaminants that a tomato could ‘suck up’ if submerged in cold water.

“Water is an automatic first suspect. Was clean water used to irrigate, mix pesticides sprayed on crops, wash down harvest and processing equipment, and wash field workers’ hands?

Then in packing houses, tomatoes often go straight into a dump tank, flumes of chlorinated water for a first wash. To guard against salmonella washed into the water in turn being sucked into the tomatoes, producers often keep wash-water 10 degrees warmer than the incoming crop, says food-safety scientist Keith Schneider of the University of Florida, also part of FDA’s tomato initiative.

Beyond packing houses, the industry points to cases where suppliers were shipped unwashed, warm tomatoes and dunked them in ice-water baths to firm them for further processing.

Another question: How often does the water have to be changed? Dirt, leaves and other sediment reduce the chlorine’s effectiveness.”

Produce handlers and packing houses could reduce the chances of accidentally passing fresh produce through improperly disinfected wash water by implementing test procedures and protocols which make use of simple, inexpensive chlorine test strips such as SenSafe^TM Free Chlorine Water Check, a product approved by the USEPA and by several states for drinking water compliance monitoring.

The manufacturer of this product also has dip-n-read test strips capable of detecting chlorine concentrations as high as 2,000ppm and as low as 0.005ppm.
