Many people believe well water cannot become tainted by contaminants because it typically comes from locations far beneath the surface. Water Testing Blog strongly suggests that you DO NOT BUY INTO THAT LINE OF THOUGHT.

We ‘yelled’ that last bit for a reason. Unwanted and potentially harmful contaminants can find their way into well water regardless of how far below the surface it comes from.

Hence the reason why well water professionals and health officials suggest having one’s well water tested yearly.

Today’s story about well water contamination came from Kansas where residents of Butler County have had to all but abandon the use of their drinking water wells because of an unpleasant chemical smell.

Specifically, the water coming out of the private wells has a gasoline like odor to it.

A bad odor and taste in the well water has some residents in a neighborhood east of Andover concerned. The Kansas Department of Health and Environment and a water testing lab are working to find the source of the problem, but residents in the area are becoming frustrated.

Eric and Brittney Hauck say the well water at their house in Butler County smells terrible and they fear it could be unsafe.

“There was the smell of gasoline, kind of a paint-thinner kind of smell,” said Brittney Hauck.

The Haucks immediately stopped drinking the water and contacted the KDHE. Ash Creek Associates out of Portland, Oregon came out to their house and tested the water.

Last week, the Haucks received the results which showed elevated levels of benzene and other contaminants. The testing company gave the Haucks bottled water and installed a charcoal filter at no charge.

A week later, the family and many other neighborhood residents are still waiting for answers from the KDHE about what’s causing their water to become contaminated. KAKE News attempted to contact both the testing company and KDHE but could not get a response because the offices were closed for the Martin Luther King Jr. holiday.

Some residents suspect the contamination may be coming from a petroleum pipeline that runs through their neighborhood. Until they can get some definitive answers about the safety of their well water, residents say they’ll continue to use bottled water for drinking, cooking and bathing. ( source )

We feel very bad for the Haucks and all the other folks in that area affected by the suspected contamination of the aquifer from which they draw their well water. Hopefully the KDHE will determine the source of the well water contamination quickly and make it so the Haucks and their neighbors can once again perform simple tasks like cooking and bathing with their well water.

Testing for benzene in drinking water?

The average person cannot obtain an off-the-shelf test kit capable of testing for the presence of benzene in drinking, tap or well water. That sort of testing must get done in a laboratory using advanced analytical techniques and equipment.

AS usual at this point we suggest contacting your local water department or board of health to see if they can provide you with a list of certified water testing laboratories. For those wishing to use a mail-in water testing service, you may want to take a look at the 83 water quality parameter test package offered by National Testing Laboratories.

Dear Sir, I mixed chlorine tablets(water purification Tablets) in water. my friend taken water in Test tube. mixed one drop of liquid then water color changed in yellow. what is name of that liquid. how to by that.please can sent details.

Hello, Kishore, and thank you for the inquiry about a liquid test reagent that turns yellow in the presence of chlorine. Based upon your description we suspect your friend used a chemical called ‘OTO’ to perform the testing. OTO stands for Orthotolidine dihydrochloride. It test for total chlorine (free chlorine plus combined chlorine collectively).

You can find OTO in most pool supply stores, as it normally comes in the more basic pool water testing kits for total chlorine and pH, the two most commonly tested pool water quality parameters.

Many companies also sell the two reagents separately since they do tend to ‘go bad’ after a year once opened and exposed to air.

If you want to perform more precise chlorine concentration testing for free chlorine, the compound most people have the most interest in (usually) when attempting to determine if water has had the proper amount of disinfectant added to it, you will want to invest in a drinking water test kit that uses DPD-based reagents. ( What is DPD? )

For an even simpler means of testing the chlorine levels in water samples you may want to consider a product such as the SenSafe Free Chlorine Water Check, an EPA Approved method for determining free chlorine concentrations in drinking water, or the WaterWorks 2 Free & Total Chlorine product that uses the same free chlorine testing method as the SenSafe Free Chlorine Water Check and also includes a separate test area for total chlorine.

Want to know more about the differences between free and total chlorine? Check out an article called Free Chlorine, Combined Chlorine, Total Chlorine.

One more thing about OTO before we go: We have heard that some countries have outlawed its use due to scientists having evidence that it may cause cancer in humans… so check local laws before making a purchase!

We hope this helps!

Hundreds of Stamford residents have registered for the health department’s new water testing program scheduled to launch early next month, leaving about a third of the tests budgeted for this fiscal year available.

Officials are encouraging Stamford homeowners to sign up for the public service, which is mandated under a new city ordinance the Board of Representatives approved late last year. The Health Department will share the data it gathers with state health and environmental agencies in an effort to better understand the scope of water contamination in the area of Scofieldtown Park.

The park is the site of a former landfill and had been thought for years to be the source of potentially cancer-causing chemicals discovered in nearby wells in 2009.

…

Premier Laboratory in Dayville won a competitive bid to perform the testing at a rate of $89.50 per test, Murray said. Homeowners will be charged a flat $100 fee, which will cover the cost of the test itself as well as mailing, printing and logistical expenses associated with the program. Murray said the public service is a good deal for Stamford residents, who would likely pay between $200 and $300 to have their well water tested privately. ( source )

Granted the testing will still cost residents $100, but one has to admit that the fee definitely ranks as a pretty decent bargain considering the alternative: full price. Local officials encourage residents to take advantage of this water testing deal and so do we.

A problem with well water clearly exists in that area and only a properly implemented (thorough) testing of well water in the region surrounding the suspected contamination site will allow officials to get a real good look at the scope and magnitude of the problem.

Removing and/or reducing VOC’s in drinking water?

Naturally the question that follows the discovery of contaminants in one’s drinking water has to do with how to remove or reduce them to ‘safe’ levels. In the article one family had a carbon block filter of some sort installed. Below you will find an example of a carbon block filter hooked up to the Pentek RO-3500 currently offered by numerous online water filter systems vendors like WaterFilters.Net and FiltersFast.Com.

She is testing for arsenic in apple juice.”

Thus far in our limited research we have found only one kit that we THINK may have the ability to perform testing on various juices: Arsenic Quick. Why do we think this kit may have promise? Quite simply, its design (hanging the test pad reaction area above the liquid getting tested and relying solely upon arsenic gas liberated by a small quantity of food grade acid) means the color of the juice ought not interfere with reading the resultant color of the test pad after at the completion of the test.

Food grade acid? Liberated arsenic gas? Is this test SAFE?

Having performed the test numerous times ourselves, we can assure you that the test procedure and required testing reagents pose little to no harm to people performing the tests.

Food Grade Acid – Instead of using more caustic and potentially dangerous acids like other kits, the Arsenic Quick Test Kit uses tartaric acid, an acid commonly found in various ingredients used in foods most of us eat on a daily basis.

Liberated Arsenic Gas – While the directions for the Arsenic Quick Test Kit instruct testing personnel to perform testing in a well-ventilated area, the amount of gas generated by such a small sample should pose no risks.

But, just the same… open a window in the kitchen and turn on the stove exhaust fan (if you have one), test in the garage w/ the door open, or take some other precaution that will keep fresh air coming into the test area.

Proper precaution in any testing environment, even if the testing environment seems safe, always pays off!

For the sake of this article, and because it would make his/her inquiry make more sense, we will assume that Malli intended to ask for a method of testing for FLUORIDE levels in water.

Regretfully we have not heard of any ‘new’ methods a person can use to detect fluoride levels in drinking water since we last addressed this topic. Therefore we will continue to suggest using a meter such as the eXact Micro 7+ Water Testing Meter that uses Fluoride (SPADNS) Reagent to detect fluoride levels in water as low as 0.1 ppm and as high as 1.1 ppm.

One could also use the mail-in fluoride testing services of a company called National Testing Laboratories to determine how much, if any fluoride their drinking water contains.

eXact Micro 7+ Water Testing Meter

Fluoride Test Reagent

So, Malli, once you determine if your water contains fluoride, next you will need to decide if you wish to remove or reduce that fluoride level… assuming you have fluoride in your water to begin with.

Removing/Reducing Fluoride Levels in Drinking Water?

When it comes to finding an effective means of reducing fluoride levels in drinking water, thus far our ‘research’ always points us down the same path… towards reverse osmosis water filters. The unit you see on the right, the Pentek RO-3500, has gone through testing and gotten certified by NSF/ANSI to Standard 58 for the reduction of Pentavalent Arsenic, Barium, Cadmium, Copper, Hexavalent & Trivalent Chromium, Cyst, Fluoride, Lead, Nitrate/Nitrite, Radium 226/228, Selenium, TDS and Turbidity.

Though definitely NOT the most expensive unit on the market, this filter has successfully passed third party testing, can produce nearly 8 gallons of crystal clear, filtered drinking water per day, and does so while reducing fluoride levels by more than 90%.

Moral of the story?

You will never know exactly how much fluoride, iron, copper, manganese, chlorine, salt, or other unwanted contaminants your water contains until you perform the appropriate tests on your water. Then, and only then, will you have the ability to make an educated decision regarding water treatment options.

While we have no evidence to support the notion that Arsenic Quick Test Kits will function properly with juice as the test specimen rather than water, we have used the kits extensively and know that the color of the juice ought not affect the results since the test pads react with ‘arsenic gas’ liberated from the sample inside the reaction vessel and not the actual water sample.

Note: We contacted the makers of Arsenic Quick Test Kits about the effectiveness of their Arsenic Quick Test Kits with juice as samples and will most certainly share any definitive information we learn.

Getting back to the topic of using Arsenic Quick Test Kits, at first the process may sound a bit complex — but trust us when we say it really does not take a rocket scientist to perform the testing. Hence the reason why a number of people, including folks at the USEPA and other high profile government (as well as non-profit) agencies, have recommended this kit as a viable and useful field testing option when faced with situations where a water source may contain inorganic arsenic as a contaminant.

At this point you may find yourself asking, “Wait, didn’t you say the test liberated arsenic gas?”

Yes, Arsenic Quick Test Kits do liberate small amounts of arsenic gas in the test vessel but the amounts generated should not pose a problem as long as the testing takes place in an area with proper ventilation. In other words, open a window, test in the garage w/ the door open or perform your testing outdoors.

Arsenic Quick Test Kits do not require typical controlled laboratory environments in order to yield quality results.

What about the science projects?

So glad you asked! Depending on where you live, Lisa, and how many bodies of water you have access to for sampling purposes, you could have quite a few really cool science projects for your daughter to work on.

A company called Water Safe manufactures a test kit called the Science Fair Project Test Kit which gives young (or old!) experimenters the ability to test up to 10 bodies of water for the following important drinking water parameters:

Bacteria	None
Lead	Below 15 ppb
Pesticides	Below 3ppb (atrazine), Below 4ppb (simazine)
Nitrite	Below 1.0 ppm
Total Nitrate/Nitrite	Below 10.0 ppm
pH	6.5 to 8.5
Total Chlorine	Below 4 ppm
Total Hardness	50 ppm or less

Do other options exist for more testing? Of course they do… but the WaterSafe Science Fair Project Test Kit offers a good sampling (8 parameters for 10 bodies of water) of tests for a reasonable cost — around $80. If that option does not suit your budget, WaterSafe also makes the same kit in a smaller size that tests up to 4 bodies of water for the same water quality parameters for around $40.

Got bigger testing plans?

If you believe you will want to perform long-term testing and will need 25 to 50 tests per water quality parameter, SenSafe manufactures a par of kits called the Well Driller Standard and Well Driller Master test kits which both come with plenty of testing supplies to keep testing projects of longer duration well-stocked.

We believe that saying has quite a lot of significance in the world of water testing, too, because water supplies all over the world could potentially have contamination issues… so testing the water locally will always make sense in our minds.

Having said that, today’s question comes to us from a gentleman named ‘Dan’ who wrote, “i live in a village in Haiti, about 30 minutes from Les Cayes. I need to test the water supply that the locals use. We suspect ground water contamination. What do you recommend?”

First of all, Dan, what sort of contamination do you suspect? More than likely we think you mean ‘bacterial contamination’ based upon the information we have read about the sanitary conditions in parts of Haiti so we will operate under that assumption.

With that in mind, take a look at products such as EZ Coliform Cult Bacteria Water Test Kit which make it possible for pretty much anyone to test for the presence of coliform bacteria in a water sample without the need for expensive lab equipment or incubation ovens. Additionally, with the use of a battery powered portable UV light source at the end of the testing period a person can positively identify E.Coli if present in the sample.

Simple things besides bacteria to test for?

The list of potential drinking water contaminants stretches on for miles and could, from estimates, possibly even circle the globe a few times!

Don’t let that daunting number dissuade you from performing due diligence by testing for some of the simpler, easier to detect and ‘definitely-worth-knowing-about’ contaminants. We will now list a few of the ones that spring to our minds right away, but please do not take this list as the final word in ‘simple’ drinking water contaminants most people can easily test for.

Now some of you may look at that collection of test kits and say, “Wow! That’s a lot to deal with!” but don’t worry, we would also like to take a moment to list for you some combination test kits that keep everything organized, provide easy-to-follow instructions and allow user to test for a number of water quality parameters.

In tests of 44 properties in Jasper County, 19 showed high levels of lead, prompting the city’s mayor to ask the U.S. Environmental Protection Agency and the Missouri Department of Natural Resources for help in testing for, and cleaning up, the element, according to the Los Angeles Times.

For more than 100 years, beginning in the mid-19th century, Jasper County was at the worldwide forefront of lead and zinc mining. The area included town names like Leadville Hollow and Minersville.

According to Dan Pekarek, director of the Joplin Health Department, a waste product from lead mining called “chat” was dumped in several spots around the city of Joplin, and simply covered with soil. Those sites we likely exposed when the F-5 tornado ripped through the city. ( source )

So… What does that mean for the residents of Joplin in terms of water quality and drinking water safety? It means they will more than likely begin regular testing for lead and other potentially dangerous metals in their drinking water!

The United States Environmental Protection Agency has determined that consuming food and drink containing levels of lead at or above 15ppb (parts per billion) can cause serious health problems.

Why did companies dump ‘chat’ all over the place?

At the time no one probably knew the dangers posed by the material so government did not really care where the material ended up. Hence the reason the article mentioned how people used it as fill material under houses, in yards, etc.

Now, however, science and the medical profession both agree that material containing such high levels of lead pose quite a threat, mining companies would need piles and piles of permits before they could dispose of a substance like ‘chat’ and they would more than likely remain on the hook for the safety of surrounding areas for many years.

Testing for lead in water? Soil?

Can the average person test for the presence of lead in their water and soil? Absolutely! SenSafe makes several affordable products that work well for field testing.

Right now (11/09/11) TestProducts.Com has SenSafe’s Lead in Water Test Kit available at a discounted rate of around 18 dollars for two tests and you can use the kit to test for the presence of lead in either soil or water.

A company called WaterSafe also manufactures a Lead in Water Test Kit, but that kit does not include instructions for determining lead levels in soil.

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.

Coliform Bacteria Test Kit

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.
