How Dangerous are the Arsenic Quick Test Kits?

Water Testing Blog — Thu, 10 May 2012 13:03:51 +0000

We recently received a rather interesting question from ‘Chmst411′ who asked, “Are your arsenic test kits dangerous? We want to do an experiment with the kids for a school project but fear the arsenic gas you say gets ‘liberated’ during testing. How dangerous IS that gas and what risk does that acid used pose?”

Having worked with the Arsenic Quick test kits for a number of years now we can honestly say that they do not pose much of a risk at all. To answer your questions more directly, though…

Liberated Arsenic Gas – While true that this test procedure does generate a very small amount of gaseous arsenic, the volume created poses no risk to test personnel as long as the test gets performed in a normally ventilated room.

Use of Tartaric Acid – All of the Arsenic Quick test procedures require the use of an acid, true, but the acid in question (tartaric acid) qualifies as a food grade acid rather than a more aggressive industrial grade acid like other test kits use. Use of tartaric acid in the Arsenic Quick test procedure poses no real danger to test personnel.

So… should you fear the Arsenic Quick Test Kits because they use an acid as a reagent and generate a small amount of arsenic gas? Not in our opinion — and as we said, we have used them many times in the past 7+ years.

Compared to the other methods available to the public for testing drinking or ground water for free, dissolved arsenic, the Arsenic Quick line of arsenic test kits have a shorter total test time, safer reagents and simpler instruction set. And yes, we have used other arsenic test kits manufactured by other companies, as well.

Arsenic Levels Found in Well Water Deemed Unsafe

Water Testing Blog — Mon, 20 Feb 2012 13:03:01 +0000

Yesterday we touched on water quality issues in California involving unsafe levels of Chromium-6, a known carcinogenic compound, in well water. Today we sadly report that the same region of the country, Coachella Valley, California, also has troubles with higher than desired concentrations of arsenic in well water.

In addition to high levels of chromium-6 found across the Coachella Valley, residents in east valley also cope with high well-water concentrations of another naturally occurring element: arsenic.

Thousands of residents live in areas that contain hazardous levels of arsenic in their groundwater, a problem that would cost millions to remedy.

In January 2010, Riverside County environmental health officials knew of wells at 19 mobile home and RV parks that had tested positive for dangerous levels of arsenic ranging from 12 to 91 parts per billion, a Desert Sun probe found.

Studies have linked arsenic, a naturally occurring tasteless and odorless element, to risks of cancer when ingested over decades at levels of more than 10 parts per billion, according to state and federal health officials. Children are even more susceptible because of their low body weight.

Federal health officials used to consider any levels of arsenic above 50 parts per billion unsafe. In 2000, they lowered the standard to 10 parts per billion, based on new studies. ( source )

For those who do not already know, “The USEPA has determined that ingesting arsenic in too high a quantity can make a person very ill and possibly even cause death. Throughout history, and possibly even in some countries today, you can find arsenic listed as an ingredient in mouse and rat poison. Additionally, the USEPA classifies arsenic as a carcinogenic compound.” ( source )

Testing for Arsenic?

As usual we will bring up one of our favorite water test kit lines, the Arsenic Quick line of home, field and industrial water testing kits for As⁺³ and As⁺⁵ dissolved in water.

We like this product Arsenic Quick product line for several reasons including, but not limited to, its use of food grade reagents for improved safety, its fast and easy testing procedures, its ability to detect very low concentrations w/o the use of a meter, and its affordability.

For under $20 the average person can get a test kit that will let them know if their well water contains unsafe levels of dissolved arsenic and the testing won’t take more than around 15 minutes.

Arsenic Quick — 2 Tests
Detection Range: 5 ppb up to 500
Dissolved Arsenic in Water

Arsenic Quick II — 2 Tests
Detection Range: 1 ppb up to 160 ppb
Dissolved Arsenic in Water

For those in need of more definitive and potentially more legally defensible water testing options, contact your local health department for a list of local laboratories certified to perform the sort of water testing you require. And, as always, if no local labs exist, companies like National Testing Laboratories offer comprehensive water testing packages that include tests for a large number potential of water quality contaminants and critical water quality parameters.

Reducing Arsenic levels in Water?

Few methods for point-of-use arsenic reduction/removal exist for homeowners except for units such as the Pentek RO-3500 Reverse Osmosis System which bears NSF 58 Certification for the reduction of unwanted drinking water contaminants such as Pentavalent Arsenic, Barium, Cadmium, Copper, Hexavalent & Trivalent Chromium, Cyst, Fluoride, Lead, Nitrate/Nitrite, Radium 226/228, Selenium, TDS and Turbidity.

Other, more robust 4 and 5 stage reverse osmosis systems such as the Goldline 5-Stage Reverse Osmosis System also bear the NSF 58 mark and include additional features such as pre and post carbon block filters for additional water polishing.

Science Fair Project: Testing for Arsenic in Apple Juice?

Water Testing Blog — Wed, 25 Jan 2012 02:24:02 +0000

With so many news outlets discussing recent findings of arsenic in bottles of apple juice bearing brand names it comes as no surprise to us that we would receive an inquiry like the one we just got from ‘Hadiah’ who asked, “I would like to know exactly what arsenic testing kit i could use for my daughters science fair project. She is testing for arsenic in apple juice.”

Arsenic Quick™
0, 5, 10, 20, 50, 100, 200 & >500 ppb

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!

Testing for Arsenic in Juice

Water Testing Blog — Tue, 13 Dec 2011 02:39:09 +0000

We knew that this question would come along sooner or later. ‘Lisa’ wrote in and asked, “can my daughter use the arsenic water testing kit on juice? can you recommend any ideas for a science fair project?”

Arsenic Quick — 5 Tests
Detects <0.5 ppb to >50 ppb
Inorganic Arsenic (As+3 & As+5)

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?”

WaterSafe Water Test Kit
for Science Projects

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.

Teen Dies From Suspected Arsenic Poisoning

Water Testing Blog — Wed, 01 Jun 2011 17:07:59 +0000

Though the final word on how a 17-yr old boy may have succumb to the evils of arsenic poisoning have not come to light, it has raised the question of how much arsenic the water in a region of Australia really contains.

Up until this point no comprehensive studies of arsenic in water concentrations have taken place in this particular region (Mount Bundy Station, located 100 kilometers south of Darwin) and at least one person thinks that needs to change… Immediately.

An environmental engineer has called for more water testing in the Northern Territory following the death of a teenager of suspected arsenic poisoning.

17-year-old Ben Witham died last week in hospital after becoming ill on Mount Bundy Station, 100 kilometres south of Darwin.

Dr Gavin Mudd, from Monash University says little is known of the levels of arsenic concentrate in local water sources, particularly around retired mines.

“From a basic sustainability or environmental perspective, we should be gathering good data to prove there are no problems,” he said.

“Just because we have no data to show and we believe there’s no problem, that’s a very dangerous approach from a public health perspective.”

Northern Territory Police are preparing a file for the South Australian coroner, who is investigating the death. ( source )

What could the testing reveal?

Most importantly it could reveal whether or not residents in the area have received unusually high amounts of exposure to arsenic through their drinking water. Conversely, and just as important, it could reveal that water in the region has not become contaminated (to an appreciable extent) by local abandoned wells, the likes of which have caused contamination issues in other areas of the country (and world).

How difficult is it to test for arsenic in drinking water?

In a case like this we suggest that residents defer to the advanced equipment and sampling techniques used by qualified/certified water testing professionals. Then, once results (hopefully) come back with in an acceptable range, local residents could use a test kit from the Arsenic Quick line of water test kits to perform field testing to make sure no new sources of arsenic contamination have influenced the quality of their water.

Filter to Remove Chloramines

Water Testing Blog — Fri, 13 May 2011 01:50:57 +0000

Not a fan of chloramines in your drinking water? You now have a means of removing those pesky chloramines!

Chloramines? What are chloramines? Take a look at this earlier Water Testing Blog entry on Free Chlorine, Combined Chlorine and Total Chlorine and get a quick education on the topic!

Whether created as a byproduct of disinfection via free chlorine or the intended disinfectant in a water system, most people do NOT like the taste and odor of chloramines in their water.

Thankfully Pentek has come out with a product called the Pentek ChlorPlus 10 Chloramine Removal Water Filter Cartridge that fits in standard 10″ (x 2.5″) filter housings used in filter sytems produced by companies such as Pentek (obviously!), US Filter (recently acquired by Pentek!), Cuno, Filterite, Keystone, US Water, Water Resurces, Harmsco, and many other popular brands of water filtration systems. If your system uses a standard 10″ x 2.5″ housing, the Pentek ChlorPlus 10 ought to fit just fine!

Having said that last bit, please check the dimensions of your current filter and/or housing before ordering this product!

Looking for a 10″ replacement filter with NSF Certification? The Pentek ChlorPlus 10 uses a component tested certified to NSF Standard 42.

What does the Pentek ChlorPlus 10 remove/reduce? Using 1 micron carbon block technology this product (255416-43) should seriously reduce chloramine concentrations in drinking water and in doing so remove the (offensive) taste and odor associated with chlorine while also helping to pull out unwanted sediment, if present.

Springtime Water Testing Suggestions

Water Testing Blog — Wed, 02 Mar 2011 04:03:17 +0000

Warmer weather in most of the Northern Hemisphere means a lot more water will start to flow from one place to another… and as it does it could pick up all sorts of unpleasant, and potentially harmful, drinking water contaminants.

As an example, the rise and fall of aquifer levels in certain parts of the United States can have a pronounced effect on dissolved arsenic levels in the water contained in those aquifers.

As a second example, water from melting snows or from Spring showers traveling across the land in agricultural regions has a tendency to pick up potentially harmful bacteria and nitrates/nitrites that could work their way into poorly capped wells.

Simple Arsenic Test Kit

Other unwanted drinking water contaminants such as atrazine and simazine also get picked up runoff water making its way through the countryside. As you may recall, farmers in the United States used both of those compounds, especially atrazine, as an herbicide/pesticide for many years — and therefore it ought not surprise you that pockets of washed away atrazine lurk in many unsuspecting parts of the country.

State Agrees More Testing Needed at Quarry Site

Water Quality Test Kit
for 15 Different Water Parameters

No one would dare question the belief that industry has a way of making messes and leaving them for others to clean up… or just leaving them and hoping no one ever realizes a mess got made in the first place. Some folks in a New Jersey community believe they have caught a company red-handed at a closed quarry and have asked the State to step in.

Residents and public officials in Basking Ridge, NJ asked the Department of Environmental Protection (DEP) to put pressure on the operators of the closed Millington Quarry on Stonehouse Road because they had evidence which suggested contaminated soil may have gotten trucked into the site over a period of years and used as back fill material.

The DEP issued a letter to Millington Quarry, Inc. and Tilcon New York, Inc. recently stating that it requires additional soil and groundwater testing around the property of the now closed quarry… and they want the testing done in accordance with State approved testing methodologies before the cold weather begins.

Needless to say the DEP’s position pleased the residents and officials in Basking Ridge, NJ.

The Department of Environmental Protection (DEP) has called for additional soil and groundwater testing at the closed Millington Quarry on Stonehouse Road, to the approval of township officials.

Millington Quarry, Inc. and Tilcon New York, Inc., the company that had been quarrying the site before operations ceased last May, were this month informed that the DEP wants further testing at three areas of the quarry where water and soil samples showed a limited presence of contaminants. A letter to the quarry on Oct. 16 called for the quarry to follow the state’s methodology in conducting the additional testing before the onset of cold weather.

…

The township has been embroiled in a legal dispute with the quarry based on suspicions of contaminated soil being trucked into the property over a period of several years. The soil was used to fill in steeply quarried areas. Random testing of some of those truckloads by a township consultant identified the presence of some contaminants, according to township officials.

David Oster, a section chief with the DEP’s office of Brownfields Remediation & Reuse, wrote in his Oct. 4 letter that the quarry’s limited groundwater investigation into wells on the site had shown elevated levels of arsenic, lead and other volatile chemicals in one well, and arsenic exceeding the DEP’s standards in another.

The letter also reported findings of pesticides and other contaminants in some soil samples that exceed the DEP’s standards for residential and non-residential soil cleanup criteria. The quarry owners have long had plans to eventually sell the closed quarry property for redevelopment with home sites. ( source )

Stories like that make us wonder how many companies have knowingly dumped loads of fill material they knew contained higher than expected and/or allowed levels of contaminants in places — and gotten away with it. On second thought, maybe we don’t really want the answer to that question. It might scare us a lot more than we’d like!

Spot testing pays off in the end?

Of course it does and this story proves it! Without the township hiring a consultant to perform sampling and testing on the loads of material entering the quarry the town would never have gotten the data it used to persuade the DEP to intervene.

Remember: The article said “elevated levels of arsenic, lead and other volatile chemicals in one well, and arsenic exceeding the DEP’s standards in another” which means those potentially hazardous items could have seeped into the local groundwater supply undetected and then found their way into the local population’s drinking water if someone had not stepped up done a little bit of testing.

No one will step and test YOUR water for you, though, if you own a private well… and that means whatever contaminants your well pumps up become your responsibility to detect, report and ultimately get rid of.

Well Driller Standard Test Kit tests for Free Chlorine (50 EPA-Approved tests), Ultra Low Total Chlorine (50 tests), Hydrogen Sulfide (50 tests), Total Hardness (50 tests), Iron (50 tests), Nitrates & Nitrites (50 tests), pH (50 tests), Manganese (24 tests), Water Metals (50 tests), Bacteria (1 test)

No matter how you look at it, and regardless of whether you have well water or city water, responsibility for the quality of the water coming out of your faucet rests solely on your shoulders… and if you choose not to test, then you have chosen to blindly accept any contaminants that may or may not have entered your water supply.

Kits like the one on the left will do nothing to help you — and neither will anyone else for that matter — if you don’t keep tabs on the quality of your own water supply!

Want to test for a few more important water quality parameters? If so, then upgrade to the Well Driller Master Test Kit and add 10 Arsenic Tests, 50 Copper Tests, 2 Lead in Water Tests, and 2 Pesticide Tests!

Arsenic Test Kits for Science Fair Projects

Water Testing Blog — Fri, 08 Oct 2010 13:03:01 +0000

Now that school has started many students and parents have realized that a science fair looms in the near future… and the SMART ones have started looking for ideas already. The rest will wait until the last minute and wind up putting a bunch of ants in a jar and say they started an ant farm.

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… but to tell the truth, we don’t actually MAKE that test kit OR physically sell it. The kit gets manufactured by a company called Industrial Test Systems, Inc. ( www.sensafe.com/home.php ).

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.

As for whether or not they will cut you a special deal, we cannot say. Last we heard they did have special pricing available for educators so it may prove useful to give them a call and see what they say: (800) 861-9712

Don’t forget to tell them Water Testing Blog sent ya’!

Miniature arsenic test kits for spot testing?

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.

Test 4 Water Sources
Test 10 Water Sources

WaterSafe Science Project test kits allow students of all ages to participate in educational, hands-on activities related to water quality. Avaliable in two sizes, 4-packs and 10-packs, the WaterSafe science project test kits come with all the supplies needed to test for Lead, Bacteria, Pesticides, Nitrates, Chlorine, Hardness and pH.

Each kit also comes with step-by-step instructions, an outline for the water testing project, and a convenient data sheet to record the results.

Traces of Arsenic Found in Well Water Near Elementary School

Water Testing Blog — Fri, 01 Oct 2010 13:03:42 +0000

As the title stated, routine testing of well water yielded startling results… near an Elementary School in Durham, Connecticut.

Testing of water from several wells showed higher than ‘normal’ amounts of sodium, sulfates, hardness and… dissolved arsenic.

DURHAM — Traces of arsenic in some of the town’s wells have prompted the Department of Health to encouraging residents to test their water, according to a press release posted on the department’s website.

People who live or work around Brewster Elementary School are advised to have their water tested within the next three to six weeks. The department is also asking residents to fill out and submit a report — also on the department’s website — so officials can determine the extent of contamination.

Arsenic, which causes health problems like skin discoloration (melanosis), hardening of the skin (keratosis) and cancer, can contaminate groundwater naturally and through human activities such as mining. It can also come from pesticides and fertilizers that contain arsenic. ( source )

Health officials went on to say that although certain area wells did show elevated levels of arsenic contamination, people do not need to get alarmed just yet. They do not have enough test data to reach any firm conclusions and would like the private well owners to lend a hand and by conducting testing and reporting the results via a form currently available on the Durham Department of Health web site.

For those not aware of the dangers arsenic in drinking water may pose, take a look at some of the prior articles posted on this site:

Can the general public perform arsenic testing on its own safely?

Absolutely. The Arsenic Quick™ line of arsenic in water test kits offers allows users to quickly and accurately test for dissolved arsenic (As3 & As5) in drinking water in as little as 12 minutes.
