We often get asked if people who have city/town water ought to test their drinking water from time to time. If you live in the city of Edgewood, Iowa, you no longer have to ask that question.

While the Iowa Department of Natural Resources says they do not believe any dangerous water safety issues avoided detection, the fact that a city employee responsible for testing the city’s public drinking water supply on a regular basis purchased only enough supplies for 100 tests — despite claiming to have performed 3,889 water tests between January 2006 and July 2009 — would make just about anyone curious.

A former Edgewood city employee has been sentenced to probation after he admitted that he failed to test the town’s water supply and submitted false reports to the Iowa Department of Natural Resources.

…

Harris, 43, pleaded guilty in April to one count of making false statements in a matter within the jurisdiction of the Environmental Protection Agency.

In the plea agreement, Harris admitted he sent false monthly reports to the DNR from February 2008 and July 2009. He falsely claimed testing for fluoride, chlorine and manganese. DNR tests showed less chlorine in the water than the 1.5 milligrams per liter required by state law to kill bacteria.

The review found lower-than-acceptable levels of fluoride, which reduces tooth decay, and manganese oxide, which helps remove cancer-causing radium from the water. Residents in the eastern Iowa town were not exposed to any short- or long-term health risks, a DNR officer said.

The DNR originally alleged that Harris claimed to have done 3,889 water tests between January 2006 and July 2009, but bought enough material for only 100 tests. Harris resigned in August 2009.

The investigation began after some residents complained about declining water quality. ( source )

OK, now having read that, does the statement, “DNR tests showed less chlorine in the water than the 1.5 milligrams per liter required by state law to kill bacteria.” make you feel… safe?

How about “The investigation began after some residents complained about declining water quality.” Does that give you any sense of security?

Can individuals test their city/town/tap water?

Of course they can! While only certified water testing laboratories can give the absolute last word on the safety and potability of drinking water, at-home drinking water test kits from companies like SenSafe and WaterSafe allow the average homeowner to test critical water parameters on their own, whenever they want, and for little money.

What water parameters should homeowners test?

Given the number of possible drinking water contaminants, the average homeowner would find it difficult (and expensive!) to test for them all… but as a general rule, if typically makes sense for people on city/town/tap water to test for water parameters such as:

• free chlorine residual
• total chlorine residual
• lead in water
• copper in water
• iron in water
• total hardness
• bacteria in water
• hydrogen sulfide

Should homeowners with city water test for other things? That all depends on where their water company gets its water. As an example, if the water comes from a well, other potentially harmful water contaminants such as pesticides and arsenic could find their way into the water supply and an ill-equipped water treatment facility may not have the proper technology installed to remove them.

As always, though, if you have serious reason to suspect that your tap water has ‘issues’, seek advice from certified water quality experts. Home water test kits serve as great field tests, but the final word regarding a water supply’s potability should come from a certified water testing laboratory.

While the average person does not have a need to for chlorine levels much above 3 to 5 parts per million, and even then they would typically only need to do so to make sure their swimming pools had a sufficient amount of free chlorine, but other folks have the need to test for free chlorine levels in excess of 25 or 50 parts per million on a regular basis. Below we will list a few of the places where you might expect to see a need for high range free chlorine testing.

Fruit & Vegetable Processing

After fresh produce leaves the fields it travels to a processing facility where it typically gets washed with a solution containing some sort of sanitizer such as chlorine, ozone, etc. In cases where the produce processing plant uses chlorine employees must make sure the rinse water contains a certain amount of free chlorine after it has passed over the fruit/vegetables.

Levels of free chlorine drop with an increase in biological load (contamination) and the rinse water having free chlorine left after use indicates that the produce no longer contains biological contamination on its surfaces.

Childcare Facilities

State laws require that childcare facilities clean their surfaces with properly mixed sanitizing and disinfecting solutions that contain an appropriate concentration of sanitizing or disinfecting chemicals. In many cases these facilities use chlorine bleach solutions for cleaning purposes.

As a general rule these solutions must contain anywhere from 50 to 200 parts per million free chlorine for sanitizing solutions and anywhere from 500 to 800 parts per million free chlorine for disinfecting solutions. In case like this the Waterworks High Range Free Chlorine Test Strips will not work because they have an upper detection limit of only 120 parts per million free chlorine, but WaterWorks Free Chlorine Check Ultra High II has an upper detection limit of 2,000 parts per million free chlorine and works well in this application.

Some states leave it up to individual childcare facilities to determine testing frequency of sanitizing and disinfecting solutions while other states, like North Carolina for example, have strict laws dictating how often childcare facilities must perform testing.

As of January 1, 2006, all licensed, non-in-home daycare centers in the State of North Carolina had to have the ability to test the chlorine bleach content in both their sanitizing and their disinfecting solutions. Previously the law stated that they had to test only the chlorine concentration in their sanitizing solutions. ( source )

If interested in purchasing a test kit for testing sanitizing & disinfecting solutions in a childcare facility, you can find them readily available on the Filters Fast web site.

Water Lines and Water Mains

Before a water line can go into service for the first time or go back into service after a breakage or leak has gotten repaired technicians must flush (burn) the lines with water containing a high concentration of free chlorine to clean out any and biological contaminants. Typically the technicians must test the discharge water periodically until the free chlorine level remains constant at a high level for a set amount of time.

Waterworks High Range Free Chlorine Test Strips work very well for this application.

Product-specific information about Waterworks High Range Free Chlorine Test Strips:

• Testing requires just 32 seconds
• Each bottle contains 50 ready-to-use tests
• Color chart has easily distinguished color blocks at 1, 5, 10, 20, 40, 80, 120 ppm
• No harmful chemicals or reagents to handle

Looking for a way to lower the amount of free chlorine and chloramines in the water you use in the garden… but don’t want the hassle of installing a complicated water filter?

If so, then we suggest you consider the Green Knight Hydroponic Dechlorinating Filter.

Functioning as an easily installed inline filter, the Green Knight screws right onto the average 3/4″ garden hose and promotes healthy plant growth by effectively reducing and/or removing potentially harmful chlorine from the water and also contains quartz crystals which aid plants’ absorption of vital nutrients.

Rainshow’r Green Knight uses a polyester pre-filter to catch sediment and then allows water to pass through 2 pounds of specially blended KDF55, 2 ounces of quartz crystal, and a final polishing stage which contains KDF73 filament media.

This product also comes with a sturdy 3-foot vinyl hose so that people can reap the benefits of the chlorine filter near the spigot/faucet w/o having to wrestle with a full-length garden hose. This works out well for rinsing off metal tools, washing mud off of dogs, etc.

Oh, and we learned something new while researching this product: People have found that reducing chlorine levels in rinse and wash water can greatly extend the life and luster of organic carnuba wax jobs on cars, boats, RV’s, etc.

Specific product details of the Rainshow’r Green Knight:

• Testing has shown that the unit removes 85% – 90% of Free Available Chlorine (FAC)
• Testing has shown that the unit also reduces chloramine concentrations by 65% – 75%
• Life expectancy: 30,000 gallons of source water assuming ‘average’ chlorine concentrations
• Suggested flow rate: Approximately 2 ppm
• Temperature rating: From 40F up to 110F
• Maximum pressure rating: 100 psi
• Freezing will cause irreparable damage to the unit, as will not running water through the unit at least twice a month after its first use.

Will the Rainshow’r Green Knight work as a drinking water filter?

Rainshow’r, the manufacturer of Green Knight Hydroponic Dechlorinating Filter designed this product for use in the garden and for outdoor applications, not for use a device to make water potable.

It lacks sufficient filter media capable of removing particulate matter and other contaminants such as organic chemicals, heavy metals (lead, iron, copper, mercury, etc.) and bacteria from source water.

The other day we received a question from a reader in California who asked a question about free and total chlorine readings in what she called the ‘high range’.

I work at the front desk of a company that works on water lines and the guys are always complaining about ‘powder pillers’ and so today I finally asked what a ‘powder piller’ was. I learned two things today. One never ask a cranky engineer a question unless you know what your asking cuz they’re called POWDER PILLOWS and two the guys use them to test chlorine and they are a real pain to work with on a job. Do you have something else the guys can use cuz they REALLY don’t like those things nad they don’t test very high either it seems. Thanks for helping. MandyMandy113

A very interesting question, indeed, Mandy, and definitely one many people besides yourself probably would like to have answered — especially that cranky ‘ole engineer! He probably has spent years testing for free chlorine residual in water mains using DPD-Based test kits that require users to tear open a tiny foil packet and pour a pre-measured amount of reagent powder into a small test tube or vial.

Believe it or not, opening those small foil packets, often referred to as powder pillows, and pouring their contents into tiny openings using dirty, wet hands in cold, windy conditions really DOES take a lot of concentration and effort. Who knew, right?

So anyways, Mandy, other options do exist and they have a few bonuses they your co-workers, even the cranky ‘ole engineer, might appreciate. One option in particular even has approval by the EPA for use when testing the free chlorine residual in drinking water! See how he likes THEM apples. We think he will.

The SenSafe Free Chlorine Water Check test kit for free chlorine residuals in drinking water detects free chlorine residuals as low as 0.05 parts per million in a matter of seconds and requires the user to do nothing more than dip the strip into a sample, wait a few seconds, and compare the color on the test pad to a color chart.

Now before you say, “Oh great… a test strip…” let us remind you that the USEPA has thoroughly evaluated the SenSafe Free Chlorine Water Check test strips and found them more than adequate for testing free chlorine levels in municipal water supplies.

In the past test strips had color charts with hard to read colors, but this products stands as testament to the fact that times have changed and test strip technology has progressed quite far. See for yourself.

Many people (like several of the people here at Water Testing Blog) have difficulty telling the difference between different shades of colors with red in them so the fact that Free Chlorine Water Check uses a reagent that turns different shades of blue can really make a difference in how accurately a tester can interpret test results.

Testing higher levels of free chlorine

Since Mandy’s co-workers work on water lines, they most likely need to test for higher levels of chlorine (between 20 and 50 ppm) when flushing a new line or putting a repaired water line back in service. For testing like that they probably had to dilute samples 4 or 5 to 1 so they could get readable results with their dpd-based test kits. Not a fun task, especially since they would need to carry a supply of chlorine-free water with them to dilute their test samples.

As an alternative to diluting and testing with dpd reagents, SenSafe created a dip-n-read test strip that uses the same reagent as Free Chlorine Water Check, but has the ability to accurately detect up to 120 parts per million free chlorine w/ no monochloramine interference: WaterWorks Free Chlorine High Range.

For years people have wisely invested money in shower filters designed to improve the quality of their shower water by removing chlorine, but what about those times when a person wants to kick back and relax in the tub by taking a hot bath? Shower water filters remove chlorine from only the water that comes out of the shower…

Good thing companies like Rainshow’r developed products such as the Bath 3000: Crystal Ball Bath Dechlorinator, an easy-to-use device capable of removing the chlorine from as many as 200 tubs of bath water.

Rainshow’r claims its product, the Crystal Ball Bath Dechlorinator removes up to 100% of free chlorine from your bath water in minutes.

Medical professionals and cosmetologists have often stated that removing chlorine from the water we bathe in/with will result in healthier, softer, and better looking skin.

For those not sold on the idea of removing chlorine from bath water, yet, please think about the following: Shower water containing chlorine hits your skin in spurts while bath water containing chlorine makes constant and continual contact with your skin for the duration of your bath.

Benefits of using a bath water dechlorinator include better lathering and suds’ing of soaps and shampoos, relief from dry skin, and removal of a known poison from the water. Also, with the Crystal Ball Bath Dechlorinator you will not need to mess around with plumbing fixtures, connect or disconnect any pipes, handle any toxic chemicals, or worry about changing out filters.

How does the Crystal Ball Bath Dechlorinator work? Quite simply, it converts chlorine ions to harmless chloride. Using a proprietary blend of KDF media safely locked away inside the Crystal Ball Bath Dechlorinator, it gets rid of the toxic effects of chlorine, chloramine, and chlorine gas sometimes found in bath water in a matter of minutes.

How long will the Crystal Ball Bath Dechlorinator last? That obviously depends on the amount of chlorine in your bath water to begin with and how often you take a bath, but Rainshow’r estimates that users will have to purchase a new Bath Ball approximately once a year or every 200 baths — whichever comes first.

Obviously removing chlorine from just bath or shower water will not suffice if you want to eliminate the risk of potential harm it can cause. Having said that, the first step to take involves testing for chlorine in your water supply. Use of a simple do-it-yourself chlorine test strip will give you a good idea of how much chlorine your water contains in a matter of seconds.

Once you know how much chlorine you have to remove, then you can set about selecting the correct shower water filter, countertop water filter, refrigerator water filter system or whole house water filter system.

We recently learned that the maker of SenSafe Water Test Kits has released a new version of the eXact Micro Meter Water Testing Kit that makes accurate chlorine testing with DPD-based chemistry easy for experienced testers and novices alike.

Introducing, for all your chlorine testing needs, the eXact Chlorine Photometer… a digital meter for testing chlorine that has a detection range of 0 to 11 parts per million for both free and total chlorine without the need for drop counting, crushing tablets or dissolving powders.

Using the same hardware platform as the eXact Micro 7+ Meter, this new kit comes with 100 tests for free chlorine (using DPD-1) and 100 tests for total chlorine (using DPD-4)

Aside from the 0.01 ppm resolution with +/- 0.02 ppm accuracy between 0.00 and 2.39 ppm chlorine and its high detection limit of 11 parts per million, the eXact Chlorine Photometer also offers a great deal of versatility for those who may want to test for other water quality parameters such as… Ammonia, Bromine, Chloride/Salt, Chlorine Dioxide, Chromium (in Hexavalent Form), Copper, Cyanuric Acid, Fluoride, Iodine, Iron, Low Range Total Hardness, Manganese, Nitrate, Nitrite, Ozone, Acid pH, Alkali pH, Potassium, Sulfate, Sulfide, and Turbidity.

If the need arises where you need, or want, to test for parameters other than free and total chlorine, simply pick up a bottle of the appropriate reagentstrip and follow the simple instructions in your meter’s manual.

Whether you need a basic test kit for chlorine & pH, a set of easy-to-use chlorine test strips, or an electronic chlorine testing meter, you will find the product to suit your testing needs on ChlorineTests.Com.

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.

Everyone loves a bargain, right? Well if you have waited to purchase a test kit for drinking water because you could never find one on sale, well, you no longer have a reason to wait.

FilterWater.Com recently dropped the price of Sensafe’s most popular test kit for drinking water quality, an easy-to-use test kit that tests for 15 critical water quality contaminants and does not require users to mix powders, crush tablets, or have a degree in chemistry to figure out the directions.

Considered by some the most complete do-it-yourself Water Quality Test Kit on the market, this water test kit tests up to 2 water sources for 15 critical water quality parameters and allows you to quickly and easily test your drinking water and/or check to see if your water filter does a good job.

In this particular drinking water test kit you will find the only available USEPA Approved Free Chlorine Test Strip as well as color-coded, visual, on the spot tests for 13 other parameters. The bacteria test kit, however, requires 48 hours, just as it does in kits manufactured by all other companies.

In total, the Water Quality Test Kit contains the following:

• Free Chlorine – 2 tests
• Total Chlorine – 2 tests
• Chloride – 2 tests
• pH – 2 tests
• Total Alkalinity – 2 tests
• Total Hardness – 2 tests
• Nitrate – 2 tests
• Nitrite – 2 tests
• Iron – 2 tests
• Sulfate – 2 tests
• Hydrogen Sulfide – 2 tests
• Copper – 2 tests
• Lead – 1 test
• Pesticide – 1 test
• Bacteria – 1 test

Included with the kit you will receive a chart so that you can compare your results to USEPA recommended levels is included.

And remember…

Despite the great price on this home drinking water test kit, no at-home testing can ever take the place of having a certified water testing laboratory such as National Testing Labs analyze your drinking water if you have serious reason to suspect contamination.

The Omnipure Inline Water Filter CL10ROT33-B received certification by NSF against NSF/ANSI standard 42 for the reduction of Chlorine, Taste and Odor. This filter uses granular activated carbon to reduce chlorine, taste and odor from your drinking water.

Economically priced at around $14, the Omnipure CL10RO T-33 Inline Filter has a 0.5 Micron, a water flow rating of 0.5 gallons per minutes, can handle water pressure up to 125 PSI, and has a life expectancy of 1,500 gallons or approximately 12 months.

You can use the Omnipure CL10RO T-33 Inline Filter in place of the Ametek INCF-10, Omnipure K2533 BB, and P3916.

This filter also replaces the following inline filters: Honeywell RF-66, Kenmore 46-38447 and Kenmore 4638447. The Omnipure CL10RO T-33 Inline Filter also works as Stage 5 of the 5-Stage PuROLine 5000 Reverse Osmosis System.

How Do I Know if I Have Chlorine in My Water?

Most often we hear, “How can I get rid of the chlorine taste/smell in my water?” but sometimes people have such low amounts that they cannot tell for sure if they have ANY chlorine in their drinking water and/or they have an impaired sense of smell and cannot detect the chlorine odors… but know they don’t want to drink it regardless of whether or not they can smell or taste it.

The easiest way to test chlorine levels in drinking water, Chlorine Test Strips, and at this time we recommend using test strip products from two manufacturers: SenSafe and Watersafe.

For some people the idea of a ‘tap water taste test’ makes no sense — because THEIR tap water tastes like chlorine (test for chlorine), smells like rotten eggs (test for hydrogen sulfide), has a metallic taste to it (test for heavy metals), and/or leaves deposits on fixtures (test for water hardness).

For the folks in Stevens Point, Wisconsin, though, this year the idea of a tap water taste test means honors and accolades because a panel of judges appointed by the American Water Works Association (AWWA.org) deemed their water the best tasting water (from a public water system) in North America.

(CHICAGO) – The American Water Works Association (AWWA) today announced that Wisconsin’s Stevens Point Water Department won the annual “Best of the Best” Water Taste Test. The event, composed of regional winners from water-tasting competitions across North America, was held at AWWA’s Annual Conference and Exposition (ACE10) in Chicago.

Stevens Point Water Department, now known throughout North America for its tasty water, has reliably provided Stevens Point residents with groundwater since 1922.

Second place in the competition was awarded to the New York City Department of Environmental Protection while Lincoln Water System of Nebraska and Silverdale Water District of Washington tied for third place. ( source )

So… if an area has the best tasting tap water, does that mean ever person on that water system has great water? Absolutely not!

The water used in competitions like the one above came straight from the water treatment facility… and did NOT travel through miles of water lines and the plumbing in a person’s house — and in those miles or in that plumbing any number of contaminants could enter the water.

As a general rule, most incidents of municipal tap water contamination occur because of a ‘failure’ between the water treatment facility and the faucet.

• Older water lines used metals now known to cause health issues so if your city has really old water mains, well, you do the math — and by do the math we mean wonder if your city still has lead in the walls of its service lines.

• Older homes used copper plumbing… which required solder that contained lead.

• Tree roots can have a tendency to ‘grab hold’ of buried piping and eventually some roots grow strong enough to create hairline fractures in water lines through which bacteria can enter the water supply. Tree roots can also weasel their way into water lines, thus introducing unwanted bacteria.

So whether you live in a town with the best water SUPPLY in the country or an area whose water didn’t make the final cut for this year’s competition, the end responsibility for making sure the water coming from your faucet contains no dangerous contaminants rests squarely on YOUR shoulders.

Granted if you find a problem and can show negligence on the part of the city, town, state, or some business the law will require that party to correct the problem, but rest assured they will not drop by your house periodically to test your water for potential problems.

You will have to do that.
