Well Water Question From Reidsville, NC

Water Testing Blog — Fri, 11 Nov 2011 13:03:34 +0000

We recently received an email from ‘Janelle’ in North Carolina who wrote,

“I’m trying to find someone to come test my well water. I’m in Reidsville, NC. And we are just renters I have never had well water before and I would like to know what’s in it. When it rains really hard for a few days the water smells like fish. Then sometimes like onion do you know of a company that test wells in Reidsville??”

While we do not know of a specific company that tests well water in your area, Janelle, we suggest contacting your local health department and asking them if they can provide you with a list of qualified local water testing laboratories.

Water Quality Test Kit for Well & City/Tap Water

We took the liberty of doing a quick Google Search for ‘well water testing in Reidsville, NC’ (click the link, Janelle!) and while no immediate matches popped up, a few companies appeared to have locations w/in 20 or 30 miles of where you live, Janelle.

You should also check out the EPA’s North Carolina Water Page. It contains a number of links and phone numbers that may prove useful.

Regarding the ‘fishy smell’ in well water?

Without actually testing the water we suspect that your water may contain some form of organic matter whose levels change in accordance with the changing of the level of the aquifer from which your well draws its water. From what we have read the organic matter usually does not pose much of a health threat, though in some instances it can, and it typically poses more of an aesthetic nuisance than anything else.

Sources also indicated that certain types of bacteria in one’s well may also cause well water to possess a fishy smell at times.

Regarding the ‘onion smell’ in well water?

Most resources we viewed suggested changing the anode rod in the hot water heater since it, over time, can begin collecting mineral deposits or fail in other ways that can result in water coming from the water heater smelling like onions and sometimes, though we neglected to mention this in the previous section, like fish.

Treating for onion water and fishy water?

As noted a moment ago, making sure the anode rod in the water heater has not gone bad or become encrusted with unwanted mineral deposits makes for a wise course of action if water in a home has taken on an onion or fishy smell.

One site we found said the following about diagnosing and treating water that contained foul odors:

“This type of odor may indicate the presence of organic (non-pathogenic) matter. The most common method of treatment for this type of odor is activated carbon filtration or chlorination followed by carbon filtration. It is helpful to attempt to diagnose the cause of the odor so that proper treatment is designed. You may also test your well water for bacteria and nitrates to confirm portability of the water.” ( source )

No matter what, though, Janelle, make sure you get the water tested by a certified water testing laboratory — preferably one that specializes in diagnosing problems with well water.

Well Water Testing and Fracking Contamination

Water Testing Blog — Mon, 31 Oct 2011 15:49:56 +0000

We have written about the importance of testing ground and well water before, during and after hydraulic fracturing many times in the past and will more than likely continue to do so for a long time to come. The potential (and real!) dangers posed by the injection of such large quantities of mysterious chemical cocktails deep into the Earth warrants our doing so.

Today’s question about well water testing and possible well water contamination by hydraulic fracturing came to us from a woman named ‘Terri’ in Pennsylvania who asked…

why is the cost so high to test water for fracking contamination? after the recent flooding it only cost $25.00 to see if the well water was safe to drink. is it best to have a local company test the water or should we send it to Penn State or out of state? how often after the drilling starts do you recommend water to be tested?

Thank you for this question, Terri, and we bet other folks facing the unwanted financial burden of paying for more ground/well water testing than the average homeowner with a well have wondered the exact same thing.

Well Water Testing (2 or 3 parameters)…

In our experience, well water testing that costs roughly $20 to $30 usually includes the following tests: Nitrates/Nitrites and Coliform Bacteria.

Some kits and marketed laboratory testing packages may include other tests, but not much more and definitely not nearly the number of tests included in the laboratory testing packages typically used to analyze water that may contain contamination resulting from hydraulic fracturing.

Testing for Fracking Fluid (potentially 100′s of parameters)…

From the very beginning companies that used hydraulic fracturing as a means of extracting natural gas from rock and shale formations deep in the Earth have kept the list of ingredients in their fracking fluids out of the public eye.

However, according to information posted on Wikipedia (10/28/11)…

“Chemical additives used in fracturing fluids typically make up less than 1% by weight of the total fluid. They are biocides, surfactants, adjusting viscosity, and emulsifiers. Many are used in household products such as cosmetics, lotions, soaps, detergents, furniture polishes, floor waxes, and paints.[33] Some are also used in food products. A list of the chemicals that have been used was published in a U.S. House of Representatives Report.[34] Some of the chemicals pose no known health hazards, some of the chemicals are known carcinogens, some are toxic, and the health hazards for the rest are unknown. The report does not include the concentration of each chemical used or the amount used.

A 2011 study identified 632 chemicals used in natural gas operations. Only 353 of these are well-described in the scientific literature; and of these, more than 75% could affect skin, eyes, respiratory and gastrointestinal systems; roughly 40-50% could affect the brain and nervous, immune and cardiovascular systems and the kidneys; 37% could affect the endocrine system; and 25% were carcinogens or mutagens. The study indicated possible long-term health effects that might not appear immediately. The study recommended full disclosure of all products used, along with extensive air and water monitoring near natural gas operations; it also recommended that fracking’s exemption from regulation under the US Safe Drinking Water Act be rescinded.[35]“

So as you can clearly see, the potential for harm befalling a person exposed to fracking chemicals could certainly clearly exist — even if it may take a while to happen through prolonged exposure to fracking chemicals in the air and/or in their drinking water.

With the number of chemicals and ‘other things’ possibly present in fracking fluid, and the mystery surrounding many of those additives true identities, responsible testing laboratories must use a shotgun approach when analyzing samples for the fracking fluid… because they have no solid idea of what exactly to look for.

The Best way to Test for Fracking Fluid?

Terri mentioned Penn State in her inquiry and at this point we feel the scientists at Penn State may very well have the best idea of what has transpired in that region due to their close proximity and the amount of time and resources that institution has dedicated to tracking the activities of gas drilling companies in the area.

Moral of the Story?

If companies intend to begin hydraulic fracturing in your area then you really ought to have the quality of your water tested before, during and after drilling.

If companies have already started drilling and you have not, yet, had a qualified water testing lab analyze your water, you really ought to have that testing done right away.

Water Testing for Industry

Water Testing Blog — Mon, 29 Aug 2011 13:03:57 +0000

Most days we entertain questions from folks who want to make sure industrial facilities have not somehow contaminated or otherwise altered the quality of their water. Today’s question, however, deals with testing water before it gets used in a manufacturing operation.

Hi.

We are a detergent manufacturing company here in Malta and we need to make regular checks on water that is used in the manufacturing process especially for nitrates, bacterias, sulfide and others. What you can suggest me ?

Thanks and Regards

Jesmond F.

Thank you, Jesmond, for your inquiry. Given the items you wish to test for, we have a few suggestions:

SenSafe manufactures a product it calls ‘Water Quality Test Kit‘ and we believe it contains tests for all of the items you mentioned.
Another kit made by SenSafe called the Well Driller Test Kit includes tests for all of the tests you asked about and will make it possible for you to test quite a few water samples — up to 50 samples in some cases.
No if you’d rather use a meter to perform testing, naturally we suggest the eXact Micro 7+ Meter which, according to the latest information we’ve read, can test for Ammonia, Bromine, Chloride/Salt, Chlorine Dioxide, Chromium (Hexavalent), Copper, Cyanuric Acid, Fluoride, Iodine, Iron, Low Range Total Hardness, Manganese, Nitrate, Nitrite, Ozone, Acid pH, Alkali pH, Potassium, Sulfate, Sulfide, and Turbidity. Granted the meter cannot test for bacteria, but you can always pick up tests for bacteria separately.
Speaking of separately, simple dip-n-read test strips exist for the purpose of testing each of the tests you asked about — with the exception, of course, of bacteria which uses a presence/absence ‘mug’ test procedure if you wish to test down to drinking water standards: Bacteria, Sulfides (as hydrogen sulfides) and Nitrates.

Hopefully one or more of the options above will suit your water testing needs.

Reduced Fee Water Testing

Water Testing Blog — Tue, 02 Aug 2011 13:03:31 +0000

As a special treat for the lucky residents of McHenry County in Illinois, and in honor of Safe Drinking Water Month, the McHenry County Department of Health has decided to offer coliform bacteria and nitrate testing for the reduced rate of $18.

While not the be all, end all signs of well and ground water contamination, the presence of either certainly warrants immediate action and, in our opinion, the performance of more thorough testing by a certified drinking water testing laboratory.

Testing wells regularly is the only way to determine whether well water is safe to drink; many contaminants are colorless and odorless. Water from a public or municipal water system is regularly tested for contaminants regulated by federal and state standards. ( source )

For those not living in McHenry County, we suggest contacting your local health department to see what sort of free or reduced water testing programs they have available. Many times programs of that nature go under advertised (or not advertised at all).

If no options exist that way, do not simply do nothing… it’s you water, your health… and ultimately your life!

Inexpensive screening methods exist that will allow you to quickly and economically perform basic water tests on your own that will let you know whether or not you should spend the money required for more laboratory testing.

While at-home drinking and well water test kits work as great screening tools, one should not rely on them to fully diagnose every possible water contamination problem.

We absolutely LOVE posting about free water testing… and this free water testing announcement comes to use from Scott County, Minnesota where the Minnesota Department of Agriculture will offer free nitrate testing for County residents beginning at 8 am this Saturday (7/30/11) at the county Highway Garage at 600 Country Trail E. (located next door to the county hazardous water facility).

Directions: Take Highway 282 a half-mile west of the intersection of County Road 17, Highway 282 and Highway 13.

Homeowners should bring at least a half cup of water in a clean plastic or clean glass container. Run the water for five to ten minutes prior to collecting and if you have a water filtration system installed, make sure you take a sample of water both before and after the filtration unit. People with water softeners need only take one sample, though.

Make sure you refrigerate the sample(s) if you do not intend to go and have them tested right away. Also, make sure all testing gets done within 24 hours of sample collection.

And… if my well contains nitrates? What then?

If you test your water for nitrates and find that it does, in fact, contain nitrates, you will most certainly want to have your water tested by a certified water testing laboratory in your area or by a reputable mail-in water testing lab such as National Testing Laboratories to see if any other problems exist.

Then, using the results of your comprehensive water test, select the correct water filtration system to remove and/or reduce the levels of unwanted drinking water contaminants found in your water.

Nitrate Filters for ‘Big Blue’ Filter Housings

Water Testing Blog — Wed, 06 Jul 2011 13:03:07 +0000

Yesterday we discussed a few testing and removal options for nitrates. Today we’d like to address an issue brought to our attention by several readers: nitrate filters for existing filter housings.

A good number of water filter companies have started using one of several common sizes (20″x2.5″, 10″x2.5″, 20″x4.5″, 10″x4.5″) for their housings in an effort to standardize product lines between manufacturers and give consumers more filtering options once they own a particular type of filter system.

Many people refer to those sizes as ‘big blue’ sizes since at one time, and still to this day, a very popular brand of water filter (Pentek) manufactured its products using blue polypropylene.

Free Testing for Nitrates Drinking Water

Few words capture the attention of people more easily than the word ‘free’. The very idea of getting something (hopefully of worth) in exchange for absolutely nothing appeals to the deepest, most sincere part of the human soul.

Picture of Blue Baby Syndrome
Source: Wikipedia User

Today we’d like to highlight the free nitrate testing program that will run from July 18 to July 20, 2011 in Douglas County, Minnesota.

Sponsored by the Minnesota Department of Agriculture and the Douglas County Soil and Water Conservation District, free nitrates in water testing will get offered to residents who bring samples of their well or tap water to the County offices in Alexandria.

Why test for nitrates?

For starters, the USEPA has deemed them a health hazard if consumed in too great a quantity — especially for young children and babies.

A condition known as Blue Baby Syndrome, experts believe, may result when nitrates hinder the ability of hemoglobin to carry oxygen in the bloodstream.

Reduced amounts of oxygen in the bloodstream can cause developmental problems and could even result in the death.

ST. PAUL, Minn. – The Minnesota Department of Agriculture (MDA) and Douglas County Soil and Water Conservation District (SWCD) will offer a free nitrate water-testing clinic July 18-20 at the County offices located at 900 Robert Street, Suite 102, in Alexandria. Clinic hours will be 8 a.m. to 5 p.m.

The clinic is the latest in a series of water-testing clinics sponsored by MDA. Nitrates are the most common contaminants in Minnesota’s groundwater, and in some areas of the state a significant number of wells have high nitrate levels. With that in mind, experts recommend that homeowners who get their drinking water from wells should test their water regularly.

“Nitrates in drinking water can be a risk to human health,” MDA Commissioner Dave Frederickson said. “Public drinking water supplies are monitored for nitrates, but it’s important for homeowners with private wells to check their water and take action if their water has high nitrates levels.” ( source )

For those not lucky enough to live in a place offering free nitrate testing, do not fret because everyone has the option of performing at-home testing for nitrates for less than $0.50 per test AND get dependable results in just a few short minutes. The WaterWorks Nitrate/Nitrite Test Strip gives homeowners and water professionals the ability to quickly determine if a Nitrate or Nitrite problem may exist in a body of water.

Filters to remove nitrates from drinking water?

Several different styles of filter exist to remove nitrates from drinking water. Depending upon the amount of water you want to filter and the amount of nitrates in your source water, pricing for a simple disposable nitrate removal filter start around $120, pricing for higher capacity undersink nitrate filters start around $125, and pricing for more sophisticated whole house nitrate removal systems starts around $1,370.

Teens Alarmed by Water Testing Results

We always think it a good thing when people take interest in monitoring the quality of their water supply source(s) and today we’d like to recognize the efforts of students in Derby, KS for their work in sampling and evaluating water from the Arkansas River.

Not only did these students participate during the school year as part of a class activity, but they also plan to continue sampling and testing water from the Arkansas River over the course of the Summer. Water quality parameters tested include calcium (hardness), chlorides, ammonia and nitrates. Students pull samples from both riverbank areas and from areas much further beneath the water’s surface.

When asked what they thought about the results obtained from testing back in the classroom, Dakota Denton, a junior, replied “A lot of levels are high, and they’re unsafe to drink, let alone eat the fish or any animal that comes out of the water.”

For more information on the testing performed by these students, take a look at the full news story on the KSN News Web Site

Water Test Kits for Classrooms?

Many people STILL have the impression that testing water requires complex testing equipment and mixing potentially hazardous reagents/chemicals… and an advanced degree in chemistry to interpret the results.

Trust when we say, “Get rid of those awful preconceived notions about water testing! Even children in grade school can test water these days!”

Granted they may not have the ability to test of things like antimony, strontium or one of the funky additives commonly used in gasoline, but they most CERTAINLY can test for things like Lead, Bacteria, Pesticides, Nitrates, Nitrites, Chlorine, Hardness and pH.

In fact, the WaterSafe Science Project Kit 10-pack (WS425SPT) works a comprehensive test kit for comparing the water quality of up to 10 different water samples and gives reliable water test results within minutes. The bacteria test may, however, take up to 24 or 48 hours.

Whether attempting to introduce children to the world of water chemistry or arming older students with the tolls they will need to devise their own creative science/research project, the WaterSafe Science Project Kit makes water testing for 8 basic water quality parameters safe, fun and easy!

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.

Nitrite/Nitrate Testing

Test Kit for Atrazine

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.

Water Quality in RV’s and Motor Homes

Water Testing Blog — Tue, 04 Jan 2011 13:03:06 +0000

Very little beats the feeling of freedom offered by an RV or Motor Home. Each day a person or whole family can wake up in one place, get ready for the day as if at home, travel to a whole new place over the course of the day, get ready for bed as if they had never left home.

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 pesticides such 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.

Test for Lead in Water

Test for Atrazine/Simazine

Test for Nitrates/Nitrites

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 RV-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.

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, we don’t think that would make a whole lot of sense.

Culligan RV-EZ-4

In a case like this, and we actually hate to say this, we believe most people will opt for the Culligan RV-EZ-3 because it costs roughly half as much as the Culligan RV-EZ-4.

We also see an interesting dilemma for people not not bothered by investing an extra $60 into their RV or motor home water filtration system: The Culligan RV-EZ-4 does not filter out or reduce all of the contaminants that the Culligan RV-EZ-3 does.

Clearly no easy way to determine the best product for an end user exists… but no matter how you slice it, some amount of filtration when facing a wide range of potential contaminants will always trump no filtration!

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.
