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.

Several membsers of the Water Testing Blog staff have spoken with members of the military, both currently enlisted and recently discharged, and found out that some soldiers do not have access to simple, efficient tools they can use to test potential drinking water while deployed in foregin countries.

In most cases they carry packets of sanitizing/disinfecting tablets which they can use to put into their canteens to kill off bacteria, but what about lead, arsenic, cyanide and other items which can EASILY render an entire unit inoperable and take them away from their assigned duties?

Thankfully US Army, Navy, Air Force, and Marine Corps medical units deployed around the globe now have the ability to make use of simple water quality test kits which give them the ability to read basic water quality parameters quickly and easily.

Most of us know how badly we feel after ‘a night on the town’ filled with margaritas, martinis, cocktails and body shots because of dehydration. Now try to imagine how our soldiers must feel after a few MONTHS in the desert wearing full combat gear.

Safe drinking water means safer soldiers.

Thoughts of testing water for specific chemical parameters scares a lot of folks because they remember all the horrible nights they spent cramming for an upcoming Chemistry test in high school and/or college. Trust us when we say, “We feel your pain. Been there and done that.”

You should also trust us, though, when we say you don’t need complicated chemistry sets or highly specialized training to find out if your tap water contains dangerous levels of things like:

Worried about the quality of the drinking water in your home, office or school? Inexpensive, easy-to-use home water test kits are just a click or a phone call (800-861-9712) away!

Now, of course, should the results of your home water testing for key water parameters yield results above expected and/or acceptable limits, you will most certainly want to have a certified water professional perform more advanced tests on your drinking water and at no time should you rely on home water quality test kits if you have serious reason to suspect that your water contains know carcinogens or other life threatening contaminants. Leave that sort of testing up to the Water Testing Professionals in your area.

One of the most widely used testing methods for free and total chlorine makes use of something known as ‘DPD’ which stands for N,N Diethyl-1,4 Phenylenediamine Sulfate. The addition of DPD to water samples containing oxidizers such as free chlorine, bromine, iodine, chlorine dioxide and/or permanganate results in the formation of a reddish tint to the water whose intensity directly relates to the amount of oxidizer(s) present in the water sample.

At low oxidizer concentrations water samples turn a slight shade of pink in the presence of DPD and at higher oxidizer concentrations the sample will turn blood-red orange. In extremely high concentrations of oxidizers, as in above 10 ppm, the sample will turn blood-red and then go crystal clear due to the bleaching effect of the oxidizer(s) it contains.

Other oxidizers such as ozone and total chlorine do not react directly with DPD and require the addition of a compound known as Potassium Iodide (KI) before they will react with DPD.

• DPD-1 — Used to test oxidizer levels in water samples containing free chlorine, bromine, iodine, chlorine dioxide and/or permanganate.
• DPD-3 — Useless on its own, but when added to samples already containing DPD-1 and free chlorine, total chlorine, bromine, iodine, chlorine dioxide, permanganate and/or ozone, pink through blood-red color development will occur in the sample.
• DPD-4 — The combination of DPD-1 (N,N Diethyl-1,4 Phenylenediamine Sulfate) and DPD-3 (KI) to samples containing free chlorine, total chlorine, bromine, iodine, chlorine dioxide, permanganate and/or ozone will result in pink through blood-red color development in the sample. Simply put, DPD-1 + DPD-3 = DPD-4.

DPD comes in various forms, the most common of which include tablets, powder pillows, liquids and ReagentStrips^TM. Each works equally well when used correctly and may typically be interchanged with one another, though all do have their pros and cons.

• Tablets: One of the cheapest forms of DPD available and has a very long shelf-life. Difficult to break apart and dissolve in cold or hard water samples and may leave suspended solids floating around in samples.
• Powder Pillows: Inexpensive form of DPD. Difficult to dissolve in cold or hard water samples and may leave suspended solids floating around in samples. Users also complain of ‘annoyance value’ associated with having to tear the foil pillows open and pour the DPD powder into the sample vials. Not well-suited for outdoor testing.
• Liquids: Shorter shelf-life and much more unstable than other forms of DPD, considered ‘messy’ by many users, but also probably the expensive form of DPD.
• ReagentStrips^TM: Convenient delivery method for DPD, rarely leaves undissolved solids in samples regardless of temperature or hardness, decent shelf-life, and available in bottles of 50 or individually wrapped tests (excellent for field work).

The majority of people in the United States already know that our country sends a lot of aid to foreign countries in the form of water purifiers and water quality test kits in the wake of heavy rains or other natural disasters which result in massive flooding… and now we must turn our attention to the plight of millions of Americans whose homes, neighborhoods, schools and places of business have fallen victim to the mighty power of the Mississippi River and its tributaries.

As flood waters begin to recede back towards the river banks which once held them in place, the returning residents of recently flooded areas face seemingly endless hours of cleaning, millions of dollars in property damages… and uncertainty as to what sort of contaminants the flood waters have left on their lawns, on their roads, and in their wells.

The same millions of gallons of river water which burst through levees also tore through landfills, soaked up runoff/drainage from septic systems, picked up debris from swere systems, scrapped up trash from the streets, and carried the carcasses of countless animals and bugs whose lives it claimed.

Large amounts of that ‘dirty’ water may have found its way down into aquifers through open wells and other means so now the water getting pulled from wells could contain any number of natural and/or manmade chemicals.

Individuals and companies looking to perform multiple tests on numerous water sources may want to consider picking up a water testing kit like the Well Drillers’ Master Kit, as it contains a good number of tests for items which can have and adverse effect on human health:

“Salmonella in Tomatoes”

Article Written by MIKE STOBBE, AP Medical Writer.

ATLANTA - An outbreak of salmonella food poisoning first linked to uncooked tomatoes has now been reported in nine states, U.S health officials said Tuesday. Lab tests have confirmed 40 illnesses in Texas and New Mexico as the same type of salmonella, right down to the genetic fingerprint.

An investigation by Texas and New Mexico health authorities and the Indian Health Service tied those cases to uncooked, raw, large tomatoes.

At least 17 people in Texas and New Mexico have been hospitalized. None have died, according to the U.S. Centers for Disease Control and Prevention.

Another 30 people have become sick with the same Salmonella Saintpaul infection in Arizona, Utah, Colorado, Kansas, Idaho, Illinois and Indiana. CDC investigators are looking into whether tomatoes were culprits there, too.

In Texas and New Mexico, raw large tomatoes — including Roma and red round tomatoes — were found to be a common factor in the 40 illnesses. But no farm, distributor or grocery chain has been identified as the main source, said Casey Barton Behravesh, a CDC epidemiologist working on the investigation.

“The specific type and source of tomatoes is under investigation,” she said.

Salmonella is a bacterial infection that lives in the intestinal tracts of humans and other animals. The bacteria are usually transmitted to humans by eating foods contaminated with animal feces.

Most infected people suffer fever, diarrhea and abdominal cramps starting 12 to 72 hours after infection. The illness tends to last four to seven days.

Many people recover without treatment. However, severe infection and even death is possible. Infants, the elderly and people with weakened immune systems are at greatest risk for severe infections.

In Texas and New Mexico, the patients ranged in age from ages 3 to 82. Of the 40, 38 were interviewed. Most said they ate raw tomatoes from either stores or restaurants before becoming ill between April 23 and May 27.

Another 17 cases are under investigation in New Mexico, CDC officials said.

As a result of this recent outbreak of illnesses related for foodborne contaminants, many restaurants and supermarkets have pulled tomatoes off the shelf and/or stopped serving them until they hear an official OK from Federal, State and Local Health Officials.

So if you thought water testing had very little to do with the handling and processing of fresh produce such as tomatoes, you thought wrong. At each step of the handling process the quality and nature of the water used to sanitize/disinfect, wash, rinse and clean the dirt off of fruits and vegetables needs continuous monitoring.

Monitoring Free Chlorine Levels in (Produce) Wash Water:

Many fruit and vegetable packing houses rely upon the WaterWorks^TM Free Chlorine Check test strips with a detection range of 0-25ppm to let them know if the wash water contains enough free chlorine residual to effectively keep their finished product free of contaminants.

Monitoring Free Chlorine Residuals Used to Wash Equipment:

Healh officials on every level require the operators of fruit and vegetable processing plants to clean off their machinery with a strong disinfectant solution. WaterWorks^TM Free Chlorine (High Range) test strips have a detection range of 0-120ppm, a range well suited for monitoring the free chlorine residual levels in the solutions used to hose down (wash) the equipment in a fruit and vegetable processing plant.

Making Sure No Chlorine Remains on the Fruits and Vegetables:

The presence of chlorine residual on fresh produce leads to premature rotting of the product so workers in fruit and vegetable processing plants check the total chlorine levels in water used in the final rinse stage with products like the WaterWorks^TM Total Chlorine test strips before allowing the produce to go into its final packaging.

An article published in the Health section of the http://www.dailymail.co.uk web site on June 2, 2008 stated that a study done at Birmingham University (in England) found a correlation between pregnant women drinking certain types of tap water and the occurence of serious birth defects in their unborn children.

“Drinking or even showering in tap water can double the risk of having deformed children,” says study.

Drinking tap water while pregnant may double the risk of serious heart or brain defects in the unborn child, research suggests.

A study of almost 400,000 babies found a clear link between chemicals formed during chlorination and the occurrence of a trio of birth defects.

Drinking water, showers, swimming pools and even the steam from a boiling kettle can all contain the problem chemicals called trihalomethanes, or THMs, the researchers said.

While the study was carried out in Taiwan, it is thought up to one in six British homes is exposed to levels even higher than those found to cause concern, with concentrations tending to be particularly high in the spring and autumn.

The researchers stressed it would be impractical for pregnant women to avoid tap water and said the onus was instead on the use of disinfection methods which limit levels of the chemicals.

The Birmingham University study compared details of birth defects with the level of THMs in tap water.

The analysis of almost 400,000 babies showed those born into regions where levels were around 80 per cent more likely to have a hole-in-the-heart defect and more than 50 per cent more likely to have a cleft palate.

Their odds of suffering anencephalus - a condition that causes much of the brain, skull and scalp to be missing - were almost doubled, the journal Environmental Health reports.

While birth defects are rare - occurring in about 2 per cent of births - the three flagged up in the study are among the most common.

It is thought the chemicals may harm the unborn baby directly. Alternatively they may damage the woman’s eggs. Although the study did not prove that the chemicals caused the birth defects, it is not the first to make the link.

Researcher Professor Jouni Jaakkola said: ‘Our findings don’t just add to the evidence that water chlorination may cause birth defects, but suggest that exposure to chlorination byproducts may be responsible for some specific and common defects.

THMs are the products of a chemical reaction between chlorine and organic compounds common in lakes, rivers and reservoirs.

The amount of THMs made during chlorination vary according to where the water comes from and the disinfection process, meaning highly chlorinated water does not necessarily have the highest levels.

Home water filters may not be entirely effective at removing the chemicals and bottled water may also be tainted.

Professor Jaakkola said the solution was for water companies to use disinfection procedures that keep the production of THMs to a minimum.

He said: ‘Water disinfection has an important purpose in reducing microbial load and reducing acute gastro-intestinal infections.

‘Some have claimed it is the best public health measure ever introduced.

‘We are talking about rare health effects and a modest risk increase.

‘I don’t suggest stopping using tap water but we have to be conscious that at population level some risks may be related to increased levels.’

The Drinking Water Inspectorate, which is tasked by the Government to monitor the safety of tap water, said its own, larger-scale research had failed to find a link between THMs and birth defects.

Principal inspector Sue Pennison said: ‘Obviously we will review this research, engage our health expert colleagues, and look to see if it means we need to do anything more. But there’s no reason for people to be worried.

‘Chlorination is reliable and has been used for centuries. The only reason diseases like cholera and typhoid are not in our water supply is because of chlorination.’

The water industry trade body, Water UK, said it would consider the findings but chlorination in the UK meets World Health Organisation guidelines. ( source )

Testing for Disinfection Byproducts?

There are no ’simple’ ways to test for disinfectionm byproducts (DBP’s), but homeowners can find out if the water supplied by their public water systems possibly contains disinfection byproducts by using a test kit like the WaterWorks^TM Free and Total Chlorine Test Kit. See below:

WaterWorks^TM 2 Free and Total Chlorine

The test strips above have two pads: 1 for measuring Free Chlorine Residual and 1 for measuring Total Chlorine Residual.

• No Color on Either Pad: This typically means the water contains no chlorine at all. If on a residential water system, a person may want to re-test and/or consult your local water authority. Please note, though, that the absence of free and total chlorine does NOT necessarily mean the water does not contain disinfection byproducts. A possibility exists that all of the chlorine (or chloramines) added at the water treatment plant have left the water before getting to where it was drawn for testing.
• Color on Both Pads: This means both free and total chlorine exist in the sample water and a possibility exists that the water also contains disinfection byproducts.
• Color on Free Chlorine Pad Only: This should not ever happen because the total chlorine concentration represents the sum of the free chlorine plus the combined chlorine in the water. You cannot have free chlorine registering w/o it also registering as part the total chlorine concentration.
• Color on Total Chlorine Pad Only: If the public water system uses a chlorine/ammonia based disinfectant system then the water will more than likely NOT contain disinfection byproducts. If, however, the public water system uses a free chlorine residual as its disinfectant, then a good chance exists that the water contains disinfection byproducts.

Don’t forget that you can always find out definitively whether or not your tap water contains disinfection byproducts by simply calling your local water company and asking questions. As a general rule, the law requires them to divulge that sort of information upon request to anyone who asks.

The term biguanide refers to a sanitizer that uses a complex polymer as its base rather than traditional chlorine or bromine molecules. Use of a biguanide sanitizer elimiates the offensive ‘chemical smell in a pool/spa, puts a stop to the bleaching of hair and swimwear, reduces eye irritation and makes it possible for those with allergic reaction to chlorine or bromine to enjoy a dip in the pool/spa.

Mixing Biguanide With Chlorine/Bromine?

A definite no-no. The chlorine or bromine will destroy the biguanide polymer and in some cases cause insightly preciptates to fall out of solution. You will NOT enjoy cleaning up a pool or spa in which biguanides have met up with oxidizers such as chlorine or bromine.

Switching Between Biguanide and Chlorine/Bromine Sanitizers?

For those who seek to switch from a biguanide system to chlorine/bromine system, or vice versa, make certain you remove ALL of the former system’s chemicals before adding the new system’s chemicals.

In the case where a person wants to switch from a chlorine/bromine system over to a biguanide system, they should perform a test for Total Chlorine/Bromine before adding any of the biguanide chemicals. Test strips work well for this application and pool/spa owners can choose from a number of multi-parameter test strips to get the job done:

• Pool Check 6-in-1: free chlorine, total chlorine/bromine, pH, total alkalinity, total hardness, cyanuric acid
• Pool Check 5-in-1: free chlorine, total chlorine/bromine, pH, total alkalinity, total hardness
• Pool Check 4-in-1: free chlorine, total chlorine/bromine, pH, total alkalinity
• Pool Check Low Chlorine 3-in-1: free chlorine, pH, total alkalinity

And for those who REALLY want to make sure no chlorine resides in thei water, try using the WaterWorks^TM Ultra Low Total Chlorine Strips. Their lowest detection block starts at 0.005ppm total chlorine — an incredibly detection level for a dip and read test strip!
