This is my first time in this site,so I will give my feedback after.

In water testing for conductivity, the required measurement for potable water is what level, and the level of over 550 micro siemens is potable and any effect on the taste?

Thank you

We will begin by saying that scientists define conductivity in the following manner: A given quantity of water’s ability (or inability) to conduct electricity at a specific temperature. Dissolved solids in a water sample make it possible for the sample to conduct an electrical charge and therefore the greater the quantity of dissolved (usually inorganic) solids, the great the water’s conductivity value.

With that said, 100% pure water would contain no dissolved inorganic solids and therefore conduct no electricity.

Government & Regulatory Guidelines

To our knowledge the USEPA has not, yet, included conductivity in its Primary or Secondary Drinking Water Standards so we do wonder where Geoffrey got the value of 500 micro Siemens for a threshold for potable water.

We have seen situations, however, where regulatory bodies have placed upper limits on conductivity as a means of triggering more in-depth water quality evaluations. As an example, we have read that the EPA imposed a 300 to 500 micro Siemens threshold that would stop the issuing of coal mining permits in certain areas.

Conductivity and the taste of the water?

Quite frankly we believe the taste of the water would get determined not necessarily the the quantity of dissolved inorganic solids, but rather by the nature and character of the solids. In other words, dissolved salts would impart a salty taste while dissolved metals would more than likely impart a bitter, metallic taste to the water.

Do high conductivity readings always mean unnatural or man-made contamination of a water supply?

No, not at all. Higher than expected levels of conductivity may quite often result from virtually any activity that disturbs the area around a body of water. High winds during dry weather patterns can result in dust getting blown into water and pretty much any activity that ‘loosens’ or jars loose small pieces of solids could result in additional solids finding their way into a body of water.

Scientists have not, yet, found a clear and definitive link between elevated conductivity levels and the harmful contamination of water, though waters with definite contamination issues have, in many cases, also had elevated conductivity levels.

As an example, ‘J. Mampilly’ from India installed a system and now seeks to determine if he has installed the correct unit. He asked,

I would like to know about how i can confirm the effectiveness of my water purifier. Labs in India that can certify and throw light on the camparative quality of water before and after using a water purifier. Thank You

Unfortunately we do not have familiarity with water testing laboratories in India and cannot directly assist with this situation. We can suggest, however, that you contact your local health department and ask them for a list of certified water testing laboratories in your area.

Before…

In order to know what type of filter or what filtering capabilities you should purchase, invest (yes, we said invest) in a thorough water analysis performed by a qualified water testing laboratory. Here, again, we suggest contacting your local board of health and asking them, for a list of certified drinking water testing labs. Alternatively, or if no labs exist in your immediate vicinity, you can use the services of accredited water testing companies such as National Testing Labs.

No matter what, though, always have your water tested BEFORE deciding on a water treatment system. Oh, and one more thing: Don’t think for one second that a salesperson doing an in-home water test has the same water testing tools or qualifications as a reputable water testing laboratory. Remember: 99% of all salespeople attempt to sell things and not accurately analyze a situation — especially if accurately diagnosing a situation could cost them a sale!

And after!

As ‘J. Mampilly’ has done, we should ALL take an interest in comparing the quality of water that comes out of our water filter systems. Only then will we know if the money we invested in (not spent on!) a quality drinking water filter system performs as expected.

Testing water quality beforehand gives us not only an idea of what we need to filter out of our water, but also a checklist of water quality parameters to monitor post-filtration. Should follow up water testing reveal that these ‘issues’ did not get corrected or suddenly show up months after the installation of a water system, perhaps the water filter has stopped working or never really worked properly in the first place and needs service of some sort.

And in conclusion…

Many people go through life ‘deaf, dumb and blind’ when it comes to the quality of their water — until an (initially) unexplainable health problem pops into their life. Then, and unfortunately sometimes too late, those same people get very interested in the quality of their water and want to punish or otherwise penalize others for allowing them to consume tainted, polluted and/or contaminated drinking water.

Although we feel much sympathy for the victims of poor quality drinking water, most of us here in the United States have the ability to at least once every great while perform basic testing for critical water quality parameters such as heavy metals (i.e. lead, mercury, copper, iron, etc.), coliform bacteria, pesticides (i.e. atrazine and simazine), chlorine levels (free and/or total), total hardness, total dissolved solids, and many others.

Many times the contaminants in a water supply will have no taste, carry no odor and not appear before the naked eye. Only testing will alert you to their presence.

A company we have talked about in the past, Crystal Quest, has come out with a commercial (or whole house) reverse osmosis water filter system that uses (2) two 4″ x 40″ TFC HF1 Membranes, (1) one 4.5″ x 20″ Big White 5 micron sediment filter, (1) one 4.5″ x 20″ Big White 10 micron carbon block filter and, (1) one 4.5″ x 20″ Big White 1 micron sediment filter to effectively filter source water pushed through by a single 1 HP Multistage Goulds Pump and Motor (110/220 Volts AC, 60/50 Hertz).

Neatly packaged on a powder coated (white) aluminum, lightweight frame, this unit also boasts an inline TDS monitoring system so operators can keep a watchful eye on the purity of water produced by the system.

What good does monitoring TDS do?

When operating properly, a reverse osmosis system like the one pictured here, or like smaller, point-of-use versions such as the Crystal Quest Thunder 1000 CP, which combines reverse osmosis and ultrafiltration, will strip water of pretty much any dissolved matter… so if a TDS meter detects dissolved solids in water post-filtration, then something has gone wrong during the filtration process and one or more of the filter elements may need replacing.

If, by chance, your water usage does not require such a high volume of purified water on a daily basis, you may wish to consider the 2,500 gallon commercial reverse osmosis system or, if you just need a system for in-home use, you can find a number of units worth taking a look at on the Filter Water Web Site.

• Chromium will appear in nature in one of three forms: Chromium(0), Chromium(III) or Chromium(VI).

• Chromium(0) gets used in the production of steel.

• Chromium(III) and/or Chromium(VI) may appear in compounds used for chrome plating, making dyes and pigments, tanning leather, and preserving wood.

• Chromium(III) aids the human body in its use of sugar, protein and fat, though health officials suggest not using excessive amounts of dietary supplements containing chromium compounds.

• Higher levels of chromium(VI) may cause irritation to the lining of the nose, ulcers in the nose, runny nose, and other breathing problems such as asthma, coughing, shortness of breath, and/or wheezing. While both Chromium(III) and Chromium(VI) in air can cause the aforementioned problems, effects occur at much lower concentrations of Chromium(VI) than Chromium(III).

• Chromium(III) and Chromium(VI) may exist in drinking water and have no associated tastes or odors.

• If ingested, Chromium(III) compounds tend to have less toxic tendencies and appear to cause fewer health problems than Chromium(VI) which causes anemia, irritation of the stomach, ulcers in the stomach, and ulcers in the small intestine.

• Some laboratory animals exposed to Chromium(VI) experienced sperm damage and damage to the male reproductive system.

• Some Chromium(VI) compounds may cause skin ulcers and a percentage of the population have extreme sensitivity to Chromium(VI) and/or Chromium(III) with allergic reactions manifesting themselves as severe redness and swelling of the skin.

• The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have determined that Chromium(VI) compounds are known human carcinogens. ( source )

• Some developmental effects have been observed in animals exposed to Chromium(VI). ( source )

Regulations, rules and recommendations pertaining to Chromium?

The EPA has determined that exposure to chromium in drinking water at concentrations of 1 mg/L for up to 10 days is not expected to cause any adverse effects in a child. The FDA has determined that the chromium concentration in bottled drinking water should not exceed 1 mg/L. The Occupational Health and Safety Administration (OSHA) has limited workers’ exposure to an average of 0.0005 mg/m3 chromium(VI), 0.5 mg/m3 chromium(III), and 1.0 mg/m3 chromium(0) for an 8-hour workday, 40-hour workweek. ( source )

What NSF/ANSI Standards apply to chromium in drinking water?

Standard 53, Standard 58, and Standard 62.

For more information on the specifics of those NSF/ANSI Standards and others, take a look at the NSF International Web Site. It offers a wealth of information for both the consumer AND water professionals alike.

Removing chromium from drinking water?

As far as units for the average consumer, pretty much only reverse osmosis makes any sense. One could use a process like distillation, but it has a flow rate that most likely would not meet homeowner needs and a much higher entry cost.

As an example of a reverse osmosis that carries NSF Certification for chromium reduction, you may want to take a look at the Pentek RO-3500 which has a price tag of under $270 and appears to offer a lot of filtering power for the money.

Pentek RO-3500 Reverse Osmosis Water Filters have tested and certified to NSF/ANSI Standard 58 for the reduction of Pentavalent Arsenic (Arsenic V), Barium, Cadmium, Copper, Hexavalent & Trivalent Chromium (Chromium VI & Chromium III), Cyst, Fluoride, Lead, Nitrate/Nitrite, Radium 226/228, Selenium, TDS and Turbidity.

So anyways, an independent environmental monitoring group in the Chesapeake Bay area (Chesapeake Bay Foundation) announced that results of recent water quality testing indicate definite improvements in the bay’s overall condition.

With its crab population rebounding and water quality slightly better, the Chesapeake Bay is showing signs of improvement, the region’s leading environmental group says, but the estuary remains seriously impaired and needs a strict pollution “diet” to ensure its restoration.

The Annapolis-based Chesapeake Bay Foundation upped the estuary’s overall health score by three points in its latest “state of the bay” report, while warning that it remains in critical condition, barely above a failing grade.

“That the bay is getting better is a huge development, but sadly not the whole story,” William C. Baker, the foundation’s president, said in a release accompanying the report. “Dead zones, fish kills and water contact advisories are constant reminders of how far we still must go.” ( source )

Got a body of water in your area that you’d like to keep an eye on? The Chesapeake Bay Foundation probably uses quite a few advanced tools such as multi-parameter meters to measure a wide range of critical water parameters but in all honesty, sometimes using simple tools such as a TDS Meter or Eco-Check, a very popular product which tests for nitrates, nitrites, hardness, total alkalinity, and pH all with a single dip of a test strip and typically costs less than $14.00 for a bottle of 25 tests.

Drastic changes in basic water quality parameters sometimes serve as warning signs that other, more serious water quality problems exist.

TDS Meter
0 – 9,990 ppm

First of all, we want to say that the total number of offending water departments found to have a chronic history of failing to conduct required water testing numbered… 34 out of around 2,800. For those interested in statistics, that amounts to roughly 1.2 percent of the water departments in the State of Missouri.

“Oh… Well that’s in Missouri. That sort of thing doesn’t happen where I live.”

With recent budget cuts all across the board in pretty much every department of every city government in the country… we find it hard to believe that anyone could not think that some people, somewhere, would attempt to save money by cutting corners.

Jefferson City, Mo. — The Missouri Department of Natural Resources today released a list of 34 drinking water systems in the state that have chronically failed to complete drinking water testing required by state law.

The systems listed have at least three major monitoring violations in a 12-month period. While failing to monitor does not necessarily mean the water is unsafe, routine testing by a facility is a crucial part of maintaining a safe water supply.

The department requires all public water systems to test for bacteria at least once a month to verify these systems are providing safe drinking water to the public. The vast majority of community and non-community public water systems in Missouri comply with all monitoring requirements and meet all drinking water standards. This current list of 34 chronic violators represents only 1.2 percent of the approximately 2,800 public drinking water systems in Missouri.

…

To view more details on the violators listed, visit the department’s Website at dnr.mo.gov/env/wpp/chronic/index.html.

These systems’ owners have been sent multiple violation notices in addition to certified letters informing them that chronic failure to monitor is unacceptable. ( source )

Do we think people need to immediately stop drinking water from the tap because a few water department here and there decided to cut corners when it came to testing? Absolutely not!

The United States has one of the best, if not THE best, infrastructures for the purification and distribution of safe, clean drinking water in the world. That does NOT mean, however, that problems don’t manifest themselves from time-to-time — as demonstrated by the excerpts above from an article about water testing deficiencies in Missouri over the past 12 months.

Do we think more people need to step up to the plate and take responsibility for making sure the water they drink contains no harmful bacteria? Of course we do! With so many inexpensive and easy-to-use test kits available we see no reason why people — especially private well owners — should not perform periodic testing for basic water quality parameters.

Delicious. Who’d like a glass of cloudy tap water?

Today’s question comes from ‘Tanya’ and if you have ever gone out to eat at a restaurant, picked up a glass of water, taken a sip, and then noticed cloudiness in the glass as you went to put it back down… you will understand why Tanya sent us an email.

Tanya asked, “We live in the country and obviosuly don’t have access to city water. It would cost a small fortune, they say, to connect us up to the water lines running about 5 miles from where we live. Our well gives us water that tastes OK and don’t leave stains on our stuff like we’ve read other people’s water can do but it always looks cloudy like stuff is floating in it. Is that dangerous? What can we do about it? Thanks a bunch. Tanya.”

As for whether or not your water poses any danger to you or anyone else that drinks it, well, that all depends on what contaminants it contains. Often times the visible stuff floating in your water will not harm you…

…but other times it will. Only testing can tell you if the contaminants you see in the water pose any danger.

We suggest getting your water tested by a certified water testing laboratory such as National Testing Labs or contacting your local health department to see if they offer free or low cost water testing programs in your area.

Then, depending upon what the lab report tells you, you may want to look into getting a water filter system designed to remove the contaminants it has identified.

Do NOT just run out and buy the biggest and most powerful filter you can find, though. Not all filters remove the same contaminants and believe us when we say you will get very mad at yourself if you spend a few hundred (or more) dollars on a water filter that doesn’t even remove contaminants in your water!

Need help selecting a filter? Read the tutorials on sites like FilterWater.Com, WaterFilters.Net, FiltersFast.Com, and IsoPureWater.Com

What if it’s just… non-harmful junk?

In cases when the lab comes back and tells you that your water has nothing particularly harmful in it, and that it simply contains a large number of total dissolved solids, you may want to look into installing a sediment filter designed to remove small, suspended particulates from drinking water.

As an example, the Crystal Quest Whole House Sediment Filter uses a special NSF-certified resin media which effectively removes suspended solids down to the 20-40 micron range and does other things, at the same time, to improve the quality of the water passing through it.

First, water travels through a 20″ sediment cartridge that removes unwanted contaminants such as sediment, silt, sand and dirt. Sediment filters also extend the life of water softeners, water filters, and prevents damage to control valves or pumps that you may have installed after this unit.

Second, water travels through a specially blended bed (1.5 or 2.0 cubic feet depending upon model) of sediment removal media (CQ-S 100) equipped with an Automatic Microprocessor Control valve that regulates the amount of time water spends in contact with the media. Longer contact times with filtration media typically means more effective filtering and better conditioning of the water.

Third, water travels through a 20″ solid carbon cartridge which removes or reduces levels of compounds such as chlorine and organic contaminants which typically contribute to bad taste and odor in drinking water.

Will this or any other system work for you?

Depends… You will first need to get your water tested before you even know what contaminants you need to remove.

Start there.

Two experts on the gas drilling process called hydraulic fracturing, or fracking, told a group of Pennsylvanians that they should have their private well waters tested before any drilling begins near their homes. Neglecting to have such testing performed could lead to problems if fracking contaminates their wells.

According to a report in the Citizen’s Voice, Peter Wulfhorst and Bryan Swistock, educators with Penn State Cooperative Extension, held a seminar in Luzerne County to discuss water quality issues related to fracking. If water contamination occurs within 1,000 of a drilling platform, Pennsylvania law presumes that drilling is the cause. As such, most drillers will volunteer to test wells within that area prior to beginning operations. Wulfhorst and Swistock said property owners should take the drillers up on such offers. Gas companies lose that presumption of guilt if property owners turn water testing down, Citizens Voice said.

The pair also said property owners should pay for their own testing if they can afford it. Such tests should look for barium, chloride, elevated levels of total dissolved solids, the pH factor, and methane. These chemicals are often associated with natural gas drilling. When a property owner commissions such tests, a lab employee or independent consultant should obtain the water samples and keep a copy of the chain-of-custody report.

According to Citizens Voice, Wulfhorst and Swistock also said there are some things property owners should look for after drilling commences that could indicate their well water has become contaminated. Water that “looks like Alka-Seltzer,” could contain methane, or if it leaves red stains it could have high iron levels.

…

The chemicals that make up that fracking fluid are cause for concern. They may include, among other things, barium, strontium, benzene, glycol-ethers, toluene, 2-(2-methoxyethoxy) ethanol, and nonylphenols. All have been linked to health disorders when human exposure is too high. Thanks to a move by Congress in 2005, fracking is exempt from federal regulation under the Safe Drinking Water Act, so drillers don’t have to disclose what is contained in their fracking fluids. ( source )

So tell us, people… If the gas/oil company offers to perform testing on your well water before they begin fracking, why would you NOT take them up on the offer? The logic behind NOT taking them up on the offer just… isn’t there. In fact, the very idea of NOT taking a valuable service for FREE goes against the very tenets of human nature!

Now don’t get us wrong. If the oil/gas company offers to test the water THEMSELVES and does not SHARE the results — all of the results — with land owners, then land owners should consider having testing done on their own by a licensed, certified water testing service come out to the property, take well water samples, perform testing in an accredited laboratory in accordance with accepted testing procedures, and basically make sure the data obtained from the testing could get introduced in a court of law if needed down the road.

What if land owners have already allowed drilling to begin?

Certified testing can take place at ANY time and the results of that testing will serve as the point against which the results of all future testing will get compared. So again, make sure the testing gets done right the first time!

Can homeowners do any testing on their own?

Of course! The two fracking experts (note: We still chuckle each time we use the word ‘fracking’ in that manner) stated that land owners ought to keep an eye on several basic water parameters. Changes in pH, Total Dissolved Solids (TDS), Iron, and/or Chloride levels may signify that aquifer contamination has occurred and that land owners ought to seriously consider having more in-depth testing of their well water performed.

I need to find out about the testerORP/Redox for using at the pool

And finally, what did they have to say?

Could you explain what could be tested at the pool’s water by tested ORP/Redox (ORPTester 10 model)? How often do I have to conduct the tests?

Thank you,

Ella

Thank you, Ella, for bringing up the topic of ORP Meters and what they test. Many people have heard of ORP Meters, but not many understand a whole lot about them.

Rather than get into a discussion about gaining and losing electrons that would bore everyone to tears, we will instead sum up ORP Meters’ usefulness by saying that they measure the effectiveness of oxidizers (i.e. chlorine, bromine, non-chlorine shock, and hydrogen peroxide, etc.) in the water.

For you more technical types out there, in a chemical reaction an oxidizing agent will take electrons away from other compounds/elements in the mixture and a reducing agent will donate electrons to the other compounds/elements.

Many automatic chemical dispensing systems rely upon ORP testing units to determine how much and when to add chemical sanitizers to pools.

Frequency of testing?

Whether it has to do with chlorine testing or testing for pretty much ANY pool water parameter, if your pool falls in the category of ‘public’ you will want to consult with your local health department… as regulations vary by locale.

What testing is required for public pools?

This also varies by location so once again you will want to consult with your local health department.

Oh, and before we forget, some health departments may not recognize ORP testing as a definitive way of measuring sanitizer levels. Also, simply measuring the sanitizer level in a swimming pool will not tell you everything you need to know in order to make sure the water stays safe.

Pool water parameters typically tested?

Sanitizer (i.e. free & total chlorine) levels, pH, total alkalinity, calcium or total hardness, stabilizer (cyanuric acid) levels, TDS, and water metals (i.e. iron & copper).

As we said before, you will want to check with your local health department to see what parameters they want you to test and how often they want you to test them.

Today, a woman named ‘Sylvia’ who lives in an area where a lot of drilling has started asks,

Looking to by a TDS monitor for personal use.

We have a lot of gas drilling starting where I live, I’m having my well and water checked by a professional well service. But there are a few of us that would like to have a tds monitor for after the fact to keep a check on our water instead of constantly having to pay a professional to find out if there has been any change. I would like to know if you have a tds monitor that would pick up pH, barium, chloride, and methane. iron manganese, hardness (calcium and magnesium), sodium, total organic carbon, strontium, oil&grease, detergents, lead, arsenic, alkalinity, coliform bacteria, sulfate and nitrate. Volatile organic compounds (VOC’s) or a subgroup of VOC’s called BTEX (benzene etc.) along with radionuclides like gross alpha, radium and radon.

The first thing we need to point out: TDS Meters cannot detect all of those things. This does not mean, however, that they do not have their use in monitoring water quality in regions where gas drilling, or other industrial activities, take place.

Wikipedia describes TDS in the following manner: “Primary sources for TDS in receiving waters are agricultural and residential runoff, leaching of soil contamination and point source water pollution discharge from industrial or sewage treatment plants. The most common chemical constituents are calcium, phosphates, nitrates, sodium, potassium and chloride, which are found in nutrient runoff, general stormwater runoff and runoff from snowy climates where road de-icing salts are applied. The chemicals may be cations, anions, molecules or agglomerations on the order of one thousand or fewer molecules, so long as a soluble micro-granule is formed. More exotic and harmful elements of TDS are pesticides arising from surface runoff.” ( source )

Given the possibilities of what TDS meters COULD possibly detect, one could safely say that regardless of whether or not a person lives near gas drilling or not, a sudden change in TDS readings might warrant further investigation.

Sudden and/or drastic changes in the pH levels of source water may also serve as good reason to perform additional testing so having a pH meter handy may also prove beneficial.

At-Home Testing vs. Laboratory Testing

In a situation like Sylvia’s where a myriad of both simple and complex drinking water contaminants could show up at any time, we feel confident saying that no at-home test kit will protect her and her neighbors fully and we hope that local health officials will step up to the challenge of keeping tabs on local water quality by implementing a full regimen of independent testing… instead of blindly trusting the results handed down from private industry.

Without knowing how much your local lab charges for a ‘full battery’ of testing, Sylvia, we will suggest contacting companies like National Testing Labs to see what they have to offer.

Inexpensive Spot Checking Options

As we previously stated, occasionally testing the TDS and pH levels of source water may provide clues as to whether or not it contains contaminants. You may also want to test for the following:

• Chlorides
• Nitrates/Nitrites
• Heavy Metals (Collectively)
• Heavy Metals (Independently — Lead, Copper, Arsenic, Iron, Chromium, etc.)

A company by the name of Industrial Test Systems, Inc. manufactures an excellent test kit known as the Well Driller Master Test Kit which offers a number of useful tests designed for use on well water at a reasonable price — usually around $200 — and the kits come with multiple tests for each parameter.
