Good morning, Paige, and thank you for your inquiry.

All of the water test strip products we carry bear expiration dates not from date of opening, but rather expiration dates based on manufacturing dates.

With that said, the SenSafe™ Ozone Check product (MPN 481234) packaged in bottles of 50 tests a 24 month shelf-life from date of manufacture.

Proper Storage Matters:

As with any testing product, how one stores the product before opening and after opening matters a great deal.  Water test strips exposed to excessive temperatures (high or low), sunlight, moisture, and/or chemical vapors in the air (i.e. storing chlorine test strips near containers of dry or liquid chlorine) will have a negative effect on the accuracy, range and shelf-life of the products.

About SenSafe Ozone Check:

SenSafe™ Ozone Check detects ozone levels in water as low as 0.05 ppm and as high as 0.5 ppm in approximately 30 seconds without the need for expensive meters, messy chemical reagents, or complicated test procedures.

• Current inventory (as of 12/30/14) has expiration date of August 2016.

Detection range:

• 0, 0.05, 0.1, 0.2, 0.3, 0.4, > 0.5 ppm (mg/L)

Patented SenSafe™ aperture technology:

The SenSafe™ Ozone Check water testing product provides accurate ozone level in water test results in only 30 seconds and offers sush a low detection limt (0.05ppm) because of its patented aperture technology.

Simple test procedure:

Dip one SenSafe™ Ozone Check test strip into a water sample measuring at least 50mL (roughly 1 3/4 ounces) with constant, gentle back-and-forth motion for 10 seconds.

At the end of ten seconds remove the strip from the sample, shake one time to remove excess water from the testing window, wait 20 seconds, and match the color in the aperture window to the nearest color on the color chart on the bottle.

Chicago’s first round of testing for a toxic metal called hexavalent chromium found that levels in local drinking water are more than 11 times higher than a health standard California adopted last month.

But it could take years before anything is done about chromium contamination in Chicago and scores of other cities, in part because industrial polluters and municipal water utilities are lobbying to block or delay the Obama administration’s move toward national regulations. ( source )

As some of you may recall, we wrote about chromium showing up in drinking water in the past and from the sounds of things we will very likely find ourselves writing about it many more times.

The discovery of hexavalent chromium in drinking water is renewing a debate about dozens of unregulated substances that are showing up in water supplies nationwide. Potential health threats from many of the industrial chemicals, pharmaceutical drugs and herbicides still are being studied, but researchers say there is strong evidence that years of exposure to chromium-contaminated water can cause stomach cancer.

Test results obtained by the Tribune show that treated Lake Michigan water pumped to 7 million people in Chicago and its suburbs contains up to 0.23 parts per billion of the toxic metal, well above an amount that researchers say could increase the long-term risk of cancer. ( source )

For those of you not familiar with the articles previously written about chromium in drinking water on this site, the following links will really come in handy:

• Chromium in Drinking Water
• Chromium in Drinking Water Information
• Specifics From EWG’s Report on Chromium in Drinking Water
• Meter to Test Chromium in Water

We have written more, but the ones above ought to give you a pretty good understanding of the chromium in drinking water situation facing many areas of the United States. Water supplies previously deemed ‘safe’, and we include both municipal and private water supplies in this statement, have come under new scrutiny and many do not measure up to the current quality standards.

Speaking of tests, can the average person test for chromium in drinking water? Of course they can — but as always the best testing solution comes in the form of analysis by a certified water testing laboratory.

If, however, you would like a fast and easy method to test for the presence of chromium in water, you will definitely want to take a look at the chromium test strips produced by SenSafe. They make field testing for hexavalent chromium in water a simple and inexpensive process.

But, since we CLEARLY don’t live in a perfect world, many of us have tap water that tastes nasty and could also possibly contain some unwanted nasty contaminants. Therefore, until we can make this world perfect it may make sense to install some sort of water filter in your home and/or office if you want better tasting and possibly safer drinking water.

How much maintenance do water filters require?

About a year or two ago we would have said that all water filters require at least SOME maintenance in the form of filter cleaning, filter replacement that required tools, a semi-complicated backwashing procedure, etc. but not anymore.

Recently we have seen a lot more drinking water filters enter the marketplace with claims of ‘zero or low maintenance’. As an example, a company by the name of Crystal Quest has come out with a sealed countertop water filter that uses a 6-stage filter to remove unwanted drinking water contaminants from up to 10,000 gallons of drinking water.

After the filter stops working in 1 to 3 years, depending upon the amount of contaminants in the source water, simply disconnect its hose, dispose of the unit properly, and install a new one. No plumbing experience required!

Do disposable water filters really work?

We cannot say that all disposable water filters perform as they should, but we can say that the manufacturers of this unit have proof of its effectiveness. Take a look at the unit’s water test results on the FilterWater.Com web site.

Need a test kit for your drinking water? You may want to consider a kit such as the Water Quality Test Kit offered by the makers of SenSafe Water Test Kits.

Rebeka on 4/7/2011, said: “I was skeptical at first that a product would be able to tell me something that I thought I would have to pay a professional to test. To my amazement this water test kit worked very well for me with fast and accurate results. I’m very satisfied with the product, it was very easy to use.” ( source )

So… What does the Water Quality Test Kit test for? So glad you asked!

• Free Chlorine – 2 tests
• Total Chlorine – 2 tests
• Chloride – 2 tests
• pH – 2 tests
• Total Alkalinity – 2 tests
• Total Hardness – 2 tests
• Nitrate – 2 tests
• Nitrite – 2 tests
• Iron – 2 tests
• Sulfate – 2 tests
• Hydrogen Sulfide – 2 tests
• Copper – 2 tests
• Lead – 1 test
• Pesticide – 1 test
• Bacteria – 1 test

We did say that we would provide you with feedback from more than one user, so here you go:

Michelle on 1/27/2011, said: “This water quality test kit is a great product that I would recommend to anyone. I’m in the real-estate market, and some places I show my clients have less than desirable water. This kit is an easy way for my clients to find out what they are getting into as far as there water source goes. My clients and I have found this kit very helpful and I will continue using them. A+” ( source )

So there you have actual testimonials from real people about the benefits offered by the Water Quality Test Kit. Now can you see why all of us here at Water Testing Blog like that kit so much?

For a little over 30 bucks you can test your water for 12 drinking water parameters two times and lead, pesticides (atrazine & simazine) and coliform bacteria once.

Does this test kit take the place of laboratory testing?

No, no, no, and NO. Home drinking water test kits work well as a means of performing on-the-spot testing between laboratory tests. Not at-home drinking water test kit which has the user interpret the results takes the place of water testing performed by a certified, qualified water testing lab.

If so, then you and ‘Anne’ have some thing in common. Those evil little part stealing cretins stole Anne’s instructions for her test kit!

I had ordered the test kit a year back or so.
Now want to use the 2nd, duplicate set.

Anne

We would love to help you, Anne, but honestly we don’t have a clue as to which test kit you purchased or from what company you bought it. We would guess, though, that since you mentioned ‘second set’, that you may have purchased the Water Quality Test Kit from SenSafe.

If so, then you will find a link to that particular kit’s instructions and color charts under the image above. We hope this helps!

Looking for a water test kit?

We know of several reputable online merchants who carry reliable and affordable water quality test kits manufactured by industry leaders like SenSafe and WaterSafe.

• Filters Fast
• Filter Water
• Isopure Water
• Test Country
• Test Products
• Water Filters

Below you will find a few of the more popular water test kits offered on several of the sites listed above. These represent but a small fraction of the water quality test kits available these days so in our opinion, if anyone says, “I can’t find the right test kit”, they really haven’t looked for one.

Something to think about: The faucets and showers in motor homes use water from whatever and whichever filling station the motor home’s owner finds when it comes time to refill the storage tanks. Where did that water come from? Do you know? Probably not.

If traveling out in an area where a lot of agricultural activity takes place you may want to think about the possibility that the water contains harmful herbicides/pesticides like as atrazine. Additionally, potentially harmful levels of nitrates and/or nitrites may also exist in the water… especially if the water comes from a well.

Note: As far as we know, the chlorine tablets people add to motor home water storage tanks do nothing to reduce or eliminate the risks associated with ingesting pesticides (i.e. atrazine), nitrates, nitrites, heavy metals such as lead, lindane, MTBE, and other possible drinking water contaminants.

Does anyone make water filters for RV’s and motor homes?

As a matter of fact, a widely recognized leader in the personal drinking water filtration industry, Culligan manufactures an NSF Certified line of RV & Marine Water Filter Systems:

• Culligan RV-EZ-3 — Reduction Claims Validated for this unit by NSF: Atrazine Reduction, Cyst Reduction, Lead Reduction, Lindane Reduction, Turbidity Reduction, Chlorine Reduction (Aesthetic), Nominal Particulate Reduction (Class I), Taste and Odor Reduction.
• Culligan RC-EZ-4 — Reduction Claims Validated for this unit by NSF: Chloramine Reduction, Chlorine Reduction (Aesthetic), Nominal Particulate Reduction (Class I), Taste and Odor Reduction, Cyst Reduction, Lead Reduction, Mercury Reduction, MTBE Reduction, Turbidity Reduction, VOC Reduction.

  The Culligan RC-EZ-4 functions as a direct upgrade to the filters included in the EZ-1 & EZ-3 RV Water Filter Systems.

Each system, as you can see, removes/reduces a different number of potential drinking water contaminants. At this point we would NORMALLY suggest water quality testing as an efficient and effective means of determining which RV Water Filter System a person should consider… but since motor homes and TV’s draw their water from a different source each time they fill up, that may not make sense financially.

So, rather than spend a small fortune on testing supplies everyplace one stops to fill up the water tank(s), why not simply invest in a water filter so you don’t have to think about it anymore?

Clearly no one solution will work for all those who roam about the country in RV’s but no matter how you slice it, some amount of filtration when facing a wide range of potential contaminants in one’s water supply will always make more sense than having no filtration at all!

Testing the water before you fill up?

Although in most cases people probably do not have a whole lot of options when it comes to where they can fill up their RV or motor home water tanks while traveling through unfamiliar areas, it probably would not hurt to run a spot check on the water before hooking up.

A quick check for basic (and important!) drinking water parameters may keep you from filling your tank(s) up with water that will continue to harm you and your family until all its contaminants get diluted — some 5 or 10 fill ups later, depending upon how far you drain tanks down before refilling.

Remember: You always have the option of using bottled water for a brief stint if the water at a one particular filling station fails to make the grade!

Water test kits for RV’s and motor homes?

Hmmm… Until now we never really gave it a lot of thought. Having said that, both SenSafe and WaterSafe make excellent, and highly portable, water quality test kits that pretty much anyone can afford and use.

Water Metals Test Kit

Ordinarily when a water treatment facility’s product tests positive for too great a concentration of a heavy metal such as lead, copper, iron, mercury, etc. all sorts of people — especially environmental watchdog groups — lay the blame on the doorstep of the water treatment facility.

But not this time. Environmental Working Group (EWG), a lobbying group hailing from Washington, D.C., regards the finding of hexavalent chromium in several public water supplies as a problem, yes, but not necessarily all the fault of local water treatment facilities.

Instead, EWG would like for people to place the blame with the sources of chromium contamination.

Makes perfectly good sense to us. Stopping the flow of pollutants from entering the water supply sure would take a lot of the burden off of water treatment plants and ultimately off of the end user… AKA: All of us in the general public.

A Washington D.C. based environmental group says it’s not trying to put blame on local cities for contamination of hexavalent chromium. A single sample taken an Avion Water Company customer’s tap was one of 35 taken across the country that showed levels in excess of what the State of California is proposing as a public health standard. “This is an upstream pollution problem that needs to be stopped at the source. We need better water source protection and while we do advocate all utilities do their own testing for this and let their all their customers know the results, this doesn’t mean that they’re the ones responsible for the pollution.”

Leanne Brown with the Environmental Working Group says the only consumer level filtering system that can remove this chemical is a reverse osmosis system. Hexavalent chromium can come from manufacturing, pulp mills, and leather tanning. ( source )

So where does that leave average people like us? In the exact same place as before this result… in charge of making sure we have safe, clean drinking water going into our glasses.

Obviously a problem with chromium-6 pollution exists in this country and we, as end users, will not know whether or not we personally have chromium-6 (hexavalent chromium) in our own water supplies unless we perform testing on a periodic basis.

How to test for chromium-6 (hexavalent chromium) in your water

As usual, nothing beats laboratory testing of your water by a certified water testing laboratory (i.e. National Testing Labs)… but that does not mean each and every test needs to get shipped off to a lab.

Periodic testing for chromium-6 using at-home drinking water test kits between annual (or more frequent) lab testing provides continual piece of mind and does not cost a fortune.

SenSafe manufactures a simple dip-n-read test strip for hexavalent chromium (chromium-6) that provides results in under 2 minutes… and 50 tests costs somewhere in the neighborhood of around $14.00 (about $0.28 per test!).

Detection Levels for the SenSafe product: 0.1, 0.25, 0.5, 1, 2.5, 5, 10, 25, 50 mg/L (parts per million).

If we found one metal, might there be more?

No one can answer that question honestly… without conducting additional testing. A home or business owner might assume that the presence of chromium or other heavy metals such as lead, mercury, etc. also exist in their water supply, but as we said, without additional testing no one will know for sure.

A good way to test for metals commonly found in drinking water?

If you want a fast and inexpensive testing method for metals in drinking water that will tell you if you have a dissolved metals concentration greater than 10 parts per billion in your water, take a look at the Water Metals Check Test Strips.

While this product will not tell you exactly WHICH metal(s) your water contains, it will allow you to quickly and easily determine whether or not you will want to opt for other, more ion specific testing.

Sensafe EZ Coliform Cult E.Coli Test Kit

Many times you have seen us post articles urging private well owners to test for the presence of bacteria in their wells on a regular basis — ‘cuz no one else will ever volunteer to do it for them. We have even given links to a basic bacteria in water test kit from two different companies (SenSafe & WaterSafe) and to a more advanced bacteria test kit from SenSafe that lets a person find out not only if they have coliform bacteria present in their water, but also if they have E. Coli present.

Today we have information about the ‘tools’ required to take full advantage of the advanced bacteria test kit from SenSafe and how to properly use them to test for the presence of coliform bacteria in water samples.

How to use the Sensafe EZ Coliform Cult E.Coli Test Kit

• First of all, make sure to keep the test kit dry and in temperatures of 15-27 C (59-81 F).
• Wash hands thoroughly with soap and water before gathering your water sample. Dry hands completely.
• Carefully remove the bottle cap from the Sensafe EZ Coliform Cult E.Coli Test Kit.
• Add 100 milliliters of sample water but make sure not to overfill.
• Quickly put the cap back on the test bottle and secure it tightly.
• Shake test bottle vigorously until all of the media (solids inside the bottle) dissolve. Solution should turn a clear yellow color at this point. Turbid samples will have a less clear appearance.
• Either incubate the sample for 24 hours at 35 deg C/95 deg F — or — for 48 hours at 25 deg C/77 deg F.

• At the end of incubation period, look at the color of the sample. A yellow color indicates a lack of coliforms while a bluish green color indicates the presence of coliforms.

For those who wish to learn if their water sample contains E. Coli, two options exist:

1. Shine a UV light with wavelength 365nm from the bottom of the sample. If bright blue fluorescence occurs, the sample contains E. Coli. Where can you obtain a UV light source to perform this test? WaterFilters.Net carries the Sensafe NVF-4 Handheld UV Light.

2. Addition of Sensafe Kovacs Indole Reagent will also let you know if the sample contains E. Coli. Unfortunately we do not, at this time, have specific information regarding how this process works.

Wikipedia.org has this to say about vinyl chloride: “This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). At ambient pressure and temperature, vinyl chloride is a gas with a sickly sweet odor. It is highly toxic, flammable and carcinogenic.” ( source )

More than 300 McCullom Lake residents have signed up to get their wells tested for carcinogenic vinyl chloride at Rohm and Haas’ expense.

Of 515 surveys sent out last month by village government, 325 came back wanting the free test, while only 11 responded no, Village President Terry Counley said. Rohm and Haas offered in August to pay for it, more than four years into a series of lawsuits blaming pollution from its Ringwood plant for causing a brain cancer cluster.

“I’d say it’s a very good sign. We’re all in this boat together over here, and we need the answers,” Counley said.

Counley must select a water testing company from a list of firms accredited by the Illinois Environmental Protection Agency. Only people who signed up will get their wells tested, and Counley said he would like to get it done before winter.

Three former village next-door neighbors diagnosed with brain cancer filed the first lawsuits in April 2006, alleging that decades of seepage from a closed 8-acre waste pit fouled their air and groundwater with vinyl chloride and other chemicals.

Thirty-two lawsuits as of today blame the pollution for brain and pituitary tumors in McCullom Lake and the Lakeland Park subdivision in McHenry. ( source )

Thankfully the residents of that region in Illinois have banded together and taken a stand on the matter of well water pollution. With any hope these folks will find some answers from the testing… and after that we hope other communities will band together and investigate possible sources of suspected well water contamination.

Can the average person test their own water?

While the task of testing well or ground water for the presence of compounds such as vinyl chloride will remain in the hands of certified water testing experts such as National Testing Laboratories, the average person CAN test for other, more common drinking water contaminants.

Companies such as SenSafe and WaterSafe make easy-to-use, accurate at-home water test kits for a number of critical drinking water parameters such as arsenic in water, lead in water, bacteria in water, and heavy metals in water, etc.

Consumers have the option of purchasing drinking water test kits for individual parameters or in multi-parameter test kits such as the Water Quality Test Kit from SenSafe and the City Water Test Kit from WaterSafe.

We recently received an email from a parent whose son and friend want to perform arsenic testing on a number of water samples in their area and chart the results.

My question: My son and a co-student are wanting to do a science fair project on arsenic in the ground water. We wanted to check many samples. However, the cost of the kits are prohibitive. Is there a way that the cost of the kits may be reduced for such an endeavor?? (we wanted to use the 100 sample kit.) We would love to use your product and have it on display for the project. Please let us know if this is a possibility.. thank you so very much.

It pleases us to hear that some youngsters have taken an interest in doing a lot of ground water testing for arsenic using an Arsenic Quick Test Kit… because we know they work very well, do not require special training to use, and use safer reagents compared to other home arsenic test kits currently available on the market.

Having spoken with members of that company’s staff on numerous occasions, we can assure you that other people have successfully used versions of their field-ready arsenic test kit in science fairs in the past and done quite well.

UPDATE (8/14/2013): Previously we reported that we did not carry the Arsenic Quick Test Kit, but that has changed and the price for smaller versions as well as larger version of the product have all gone down since we first posted this article… almost three years ago!

Miniature arsenic test kits for spot testing?

In addition to full-sized arsenic test kits, we also now carry 2-test and 5-test versions of the Arsenic Quick as well as a version designed specifically for testing wood samples for arsenic.

Part Number: 481297-5 <2, 4, 6, 8, 10, 12, 15, 18, 24, 30, 40, 45 & >50ppb 5 Tests	Part Number: 481396-5 0, 5, 10, 20, 50, 100, 200 & >500 ppb 5 Tests
Part Number: 481396-5 0, 5, 10, 20, 50, 100, 200 & >500 ppb 5 Tests	Part Number: 481396-W Arsenic Test Kit for Wood 5 Tests

If memory serves us right, a student won some sort of National Award using an Arsenic Quick test kit.

Other water test kits for science fair projects?

Not all students have access to well water or surface water… but that does NOT mean they can’t use water testing as the basis of their science project. Why? Because even tap water varies from place to place and in some places its quality may vary on a daily basis.
