Today’s question came to us from ‘AnThony07′ who asked, “Pool store guys said to fix pH after alkalinity. Why not just fix the problem pH they pointed out?”

Many folks mistake pH for alkalinity and at other times they mistake alkalinity for pH. Do the two have a lot in common? Well, sort of, but they also have enough differences that they both matter and need to get addressed separately and in the correct order.

Simply put,

• pH – A measure of how acidic or basic a water sample is.

• Alkalinity – A physical count of the ‘molecules’ that make a sample acidic or basic.

Yes, yes, we know… we oversimplified that by a mile… but for most pool owners that model works quite well.

On a more real-world level, think of it this way: If you walked into a room and wanted to change the overall mood or opinion of the room, would you have better luck exacting change on a room full of people or a room with fewer people in it?

Obviously you could get the change in mood or opinion in the room if it contained fewer people, right? Well the same goes for pool water. A pool with low alkalinity will change pH very easily as a result of outside influence (i.e. addition of acidic rain water, depositing of leaves that give off acids as they decompose, etc.) whereas a pool with the proper amount of alkalinity will take longer to have its pH altered by outside influences.

Conversely, a pool with too much alkalinity could, over time, go out of balance (acidic or basic) and then it would take a whole lot of persuading (i.e. the adding of chemicals) to correct the pH — and a lot of times the pH will shoot from one end of the spectrum to the other after the addition of, for the average pool owner, an unpredictable quantity of pH correction chemicals.

So… Does alkalinity matter, Anthony? You bet it does!

Moral of the story

Before you go WASTING MONEY on chemicals to fix the pH, make sure you have the proper amount of alkalinity in your pool water! If you don’t want to travel to the pool store every time you think your alkalinity may need checking, pool water test strips such as those manufactured by AquaChek or Pool Check work quite well, cost very little and provide fast, accurate results on-the-spot.

Or, for those who want to perform more in-depth testing so they can fine tune their pool water’s quality, pool water testing meter’s such as the eXact Micro 7+ Pool Testing Meter make it possible for the the average pool owner to test for a large number of important pool water characteristics — without the need for complicated mixing, measuring and interpreting of chemical reagents.

WaterSafe Science Project Test Kit

• Lead – individual test
• Bacteria – individual test
• Pesticides – individual test
• Nitrates – individual test
• Nitrites – individual test
• Chlorine – individual test
• Hardness – individual test

Students can test various sources of water and compare the results or they can test the same water at various times to check for variances in its quality. Whichever way students decide, they will find the WaterSafe Science Project Kit very easy and safe to use.

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.

Have you tried to find a reputable water testing company in your area and had no luck? If so, then you and ‘Joyce B’ should get together for coffee because the two of you have the same trouble right now…

“I have searched for hours. How does one find a water testing company? We live in Northern Colorado and can find no information on this. It’s very frustrating.”

Yes, Joyce, we agree. The internet has become so cluttered with nonsense that finding valuable resources such as reputable water testing companies has turned into a truly annoying adventure.

Thankfully the United States Environmental Protection Agency has put together a way for people to locate certified water testing laboratories in their State of residence. For you, Joyce, the EPA’s web site directed us to the following pdf file which lists State Certified Drinking Water Labs in Colorado.

For all you other folks interested in locating a certified water testing lab in your area, take a look at the EPA’s State Certification Officers for Drinking Water Laboratories. By each name you will find a link to that particular state’s web page with links to its approved drinking water testing laboratories.

Do we have to use a lab to test our water?

We strongly advocate using a certified drinking water testing laboratory in situations where the water has not gotten tested in a long time or people have good reason to suspect contamination of some sort. That does not mean, however, that people ought not perform spot check testing on the quality of their drinking water using at-home drinking water test kits made by reputable companies like SenSafe and WaterSafe because sometimes a drastic change in an easily monitored water quality parameter (i.e. pH, alkalinity, heavy metals, etc.) can indicate the presence of a much larger and potentially much more dangerous problem.

Now that the drilling has gone on long enough, people in the affected areas have started to reap some serious financial benefits from the activity and proponents of hydraulic fracturing now say that entire communities would suffer great losses (i.e. get decimated) if companies stopped drilling for natural gas nearby.

Restaurants, stores and other businesses in communities in and around areas where natural gas companies have set up hydraulic fracturing sites have experienced tremendous gains and as pointed out during a recent 60 Minutes broadcast, one community gained over 57,000 jobs.

Proponents of fracking tout facts and figures of that nature as additional evidence that fracking presents itself as a win-win situation from all angles.

Opponents view those facts and figures as good, yes, but for how long? As soon as the gas gets extracted or vanishes for an unknown reason, so will the money and so will the jobs. Life will return to normal for the permanents of those small farming communities, right?

Sure… Except for all the drilling equipment and structures left in place because it would cost more to tear them down and truck them elsewhere. Permanent eyesores left for future generations to gaze upon and wonder if any still contain dangerous fluids that may have started seeping into the ground as the equipment sits unattended, uninspected, and without proper maintenance.

HARRISBURG, Pa. — To supporters, it’s a 21st century economic boom that will benefit millions across the Northeast. To critics, it could be this century’s biggest national eco-disaster, tainting water supplies for tens of millions.

…

Combining a new process of horizontal drilling with fracking, drillers are unlocking vast deposits there and in other formations around the U.S. such as the Barnett Shale in Texas — a boom that could ensure cheap and plentiful natural gas for many years to come for homeowners, factories and power plants.

…

The drilling frenzy in the Marcellus Shale is also credited with enriching landowners and pumping new life into trucking companies, short-line railroads, quarries and steel-pipe makers, as well as the restaurants and hotels hosting out-of-state drilling crews.

An industry-financed study by Penn State projected that the boom would generate tens of thousands of jobs and hundreds of millions of dollars in state and local taxes in the coming years.

…

However, the use of fracking is raising pollution concerns across the Northeast.

While the industry maintains that fracking has been proved safe over the decades, homeowners are coming forward with tales of wells producing brown, foul-smelling water or water polluted with methane and chemicals.

In the northeastern Pennsylvania town of Dimock, a hotspot of Marcellus Shale exploration, some residents no longer use their polluted well water and can light their taps on fire because of methane they say seeped into their wells because of drilling. ( source )

Hopefully before this whole fracking thing (that almost sounded rude, right? Ha ha.) goes too far and we place weening ourselves off of OPEC’s oil and wallowing in ‘get rich quick’ wealth over the safety of our drinking water supply… someone will step in and implement some regulations the EPA can enforce.

Some have argued that the government ought to require drilling companies to pay for mandatory third party testing of well water near drilling sites and continue to pay for testing in the affected areas long after their wells have run dry.

Needless to say, the drilling companies have fallen back on their argument that hydraulic fracturing poses no risk to the aquifers through which their boring equipment must pass because of the thick metal casing and cement drilling companies use to insulate surrounding ground from chemicals and compounds used their processes.

They also say that the actual insertion of fracking fluids takes place close to two miles below the surface, more than a mile and half away from the locations of most aquifers.

Our opinion of hydraulic fracturing?

At this point we believe erring on the side of caution makes the most and that allowing hydraulic fracturing, an industry not nearly as regulated as most others that could have serious effects on the environment, to continue unchecked could result in horrifying consequences for millions of people, if not entire vast regions of the country.

Testing of the water around hydraulic fracturing sites (by third party, independent laboratories) and compiling the data will help learn more about the effects of fracking on the environment. We believe that sort of testing and data compilation needs to get done before we let Big Business and our own greed get the best of us — and allow us to accidentally poison our own wells, the very source of our existence.

Should a pool be checked daily using The Taylor Kit and Chemtrol unit , while the pool is closed because of a chemical imbalance reading from the Chemtrol unit? The ORP reading was (456), 7.4 Ph, the Taylor Kit reading was .5/? 7.2 Ph Or should we wait a day or so and then check the chlorine levels again and hope the chemical levels have risen back to normal.

Thank you for your service and time, it is greatly appreciated.

First things first: We don’t know of ANYplace where daily testing, if not HOURLY testing, of pool water quality does not get mandated by the local health department… so your question about whether or not you should test water quality daily kind of confuses us.

Regarding the readings taken by the ‘Chemtrol’ unit, we would always suggest performing periodic manual testing just to make sure the sensors in the automatic unit have not gone out of calibration. Chemical dispensing units rely upon the readings taken by the automatic sensors to help them determine how much sanitizer or other water balancing chemical to add. Therefore, keeping an eye on the automatic sensors’ accuracy makes a whole lot of sense!

Waiting a day for levels to stabilize?

Depending upon the strength and efficiency of the pool’s circulation system, you may not have to wait an entire day. As a general rule you can retest the quality of the pool water at any time, but it makes a lot more sense to retest after the water has ‘turned over’ fully after setting the chemical feeder’s levels and/or adding chemicals.

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.

You can also find replacement reagents for several different chlorine test kits on ChlorineTests.Com, which naturally means you will find DPD tablets on the site for sure.

And now for a few basic chlorine testing facts:

• Test kits containing only OTO as their chlorine testing reagent will test for total chlorine only.

• Free chlorine testing requires DPD-1. Adding DPD-3 to the sample after adding DPD-1 allows a person to test for total chlorine.

• The USEPA has set the maximum contaminant level for chlorine in drinking water at 4.0ppm. This limit applies to both free chlorine levels and total chlorine levels.

• When testing for parameters other than chlorine, some test kits will require the use of chlorine eliminating agents such as sodium thiosulfate before testing can take place.

• Water containing the same amount of total chlorine as it does has very little or no free chlorine.

• The difference between the free chlorine level and the total chlorine level equals the chloramine concentration.

Hi – We just got a pool put in (a 24′ round) and it does not hold any chlorine. We pour a gallon in at a time and test the next day and we have almost no chlorine showing up and also our water stays cloudy. What are we doing wrong? Thanks. Annie.

Well, Annie, we will start with the type of chlorine you most likely have: liquid. Sodium hypochlorite works very well as a chlorinating agent, disperses into pool water seamlessly, and has a relatively low cost (usually around $2 per gallon if bought in 5 gallon jugs).

Aside from liquid chlorine’s tendency to bleach any clothing it touches and weigh a lot in those bulky 5 gallon containers, liquid chlorine also lacks any kind of stabilizing compound in its chemical makeup. Without a stabilizer such as cyanuric acid, the chlorine added to a pool via liquid chlorine can readily exit the pool for a number of reasons (i.e direct sunlight, warm water temperatures, etc.)

If you have not already added pool stabilizer (cyanuric acid), you may want to do so pretty soon. We do, of course, suggest you test your pool for cyanuric acid before adding any chemicals… in case some other, more insidious reason exists for your pool not holding a chlorine level.

Unsure as to how you can test pool water for cyanuric acid? You can take water to your local pool store, use a liquid test kit or use something like the 6 Way Pool Check test strip.

Other Chlorine Eaters

By any chance do you have a fair amount of leaves, tree branches, dead animals, dead neighbors, or other debris in the water? If so, the chlorine will act like a human and choose the easiest (biggest) target to attack rather than go after smaller, harder to attack targets. Get the debris out right away.

Don’t Skimp on the Filtration/Circulation

The cloudy water in your pool may come from poor water circulation and/or filtration as well as the low chlorine level you initially inquired about. Until you clear up the water, try running the filter 24 hours a day if you do not already do that.

If after running the filter a full day you do not see an increase in pump pressure on the gauge attached to the filter and/or the strength of the jets pushing water back into the pool has not diminished, you may have filter problems. Now on the other hand, if you DO see increased pressure and diminished return jet strength, backwash the filter and it will begin collecting more junk from your water at a faster rate.

Simplified List of Steps for Annie to Take

Granted we cannot possibly address Annie’s problems completely since we do not know all of the factors affecting her water condition, but the we have personally used slight variations of this advice to help quite a few people clear up their pool water.

• Remove large debris from pool, if present… especially any dead bodies.

• Test stabilizer level and adjust if needed by adding cyanuric acid per the instructions given by the chemical’s manufacturer.

• Test other critical water parameters such as pH, Alkalinity, Copper, Iron, Hardness, etc. and make corrections as needed — per instruction(s), of course.

• Add more liquid chlorine… roughly 1 gallon per 10,000 gallons of pool water.

• Run filter 24 hours a day until problem clears up.

• Backwash filter when necessary to improve filtration and water circulation.

Never hesitate to go in and pester your local pool store employees for pointers, free water testing and advice. They relish the opportunity to snicker behind your back because they cannot believe you cannot figure out what pool chemicals you need… but try not to let that deter you because they know a lot about how to properly maintain pools and generally give good advice!
