Urine, Sweat, Skin and Cosmetics in Pool Water May Cause Cell Damage

Water Testing BlogChlorine, DBP, Disinfection Byproducts, Pool Water, Water Testing

Taking a leak in the swimming pool… now shown to potentially cause harmful cell damage. As if the whole ‘Ewwwww! GROSS!!!’ factor shouldn’t have ALREADY given people incentive not to do it, right?

Well we all know how lazy OTHER people… ahem… can be.

Public swimming pools are more dangerous than you might think, a new study suggests. When sweat and urine, among other organics, mix with the disinfectants in pool water, the result can be hazardous to health.

The findings, announced this week, link the application of disinfectants in recreational pools to genetic cell damage that has been shown to be linked with adverse health outcomes such as asthma and bladder cancer.

Pool water represents extreme cases of disinfection that differ from the disinfection of drinking water as pools are continuously exposed to disinfectants. But with so many people cooling off and exercising in pools and water parks (339 million visits across the United States each year), the disinfectants are a must to prevent outbreaks of infectious disease.

Chlorine and Pee Don’t Mix

The problem occurs when the sanitizers mix with organic matter.

“All sources of water possess organic matter that comes from decaying leaves, microbes and other dead life forms,” said study researcher Michael Plewa, University of Illinois professor of genetics. “In addition to organic matter and disinfectants, pool waters contain sweat, hair, skin, urine and consumer products such as cosmetics and sunscreens from swimmers.”

These consumer products are often nitrogen-rich, and when mixed with disinfectants, these products may become chemically modified and converted into more toxic agents.

Long-term exposure to these disinfection byproducts can mutate genes, induce birth defects, accelerate the aging process, cause respiratory ailments, and even induce cancer, according to the researchers. While the new study did not examine actual effects on humans, it suggests such research might be warranted. ( source )

So listen up, all you nasty bastards and batardettes out there who find it too burdensome to cart your fun -in-the-sun frolicking butts to the bathroom: STOP PEEING IN THE POOL!

Oh, and for all of you who think, “It’s my pee, so it won’t hurt me,” all the other pee rule violators think the exact same thing.

Question: Is Well Water Better Than City (Tap) Water?

Water Testing BlogChlorine, City Water Test, Disinfection Byproducts, Ground Water, Home Water Testing, Municipal Water Test, THM, Trihalomethane, Water Quality Testing, Water Testing, Well Water

We recently received an email from Emma in North Carolina and she wrote,

We’re building a new house right on the edge of where the local water plant stops delivering water and want to know if we will be better off hooking up to the water line or having well put in. Some people say we’re lucky to have a choice, but really it’s just one more decision we have to make and we already have so many! Can you help? Thanks!

Emma

As Emma implied, sometimes having a choice makes for a lot more work – if you choose to research the options properly.

Bacteria Check Water Test Kit

Hooking up to city water offers the security of knowing that the city has to test its water routinely before distribution and must inform you if it has experienced any ‘incidents’ which may put you in danger. On the flip-side, though, you will receive a bill each month to cover the expense of testing, monitoring, filtering and purifying the water going into your new home.

Investing in a well for your new home will rid you of that pesky water bill each month, but it will also make you 100% responsible for the quality and safety of water it produces once it passes an initial test done by the well drilling company.

Well Driller Test Kit: Master

We honestly do not have an answer, Emma, because some well water comes up cleaner and more pure than any water company could ever distribute… and other well water comes up nastier than backwoods swamp water and/or containing potentially dangerous chemical compounds whose origin even the best scientists in the World have trouble locating.

Pretty much all city water contains some form of disinfectant which can create unpleasant tastes and odors in drinking water. It can also irritate skin, bleach clothing, etc. and some water systems contain obnoxious (and smelly) levels of chlorine which can make water taste absolutely wretched.

While on the topic of chlorine, the most widely used disinfectant for public water systems, produces trihalomethanes (THM’s), a potentially carcinogenic disinfection byproduct, when chlorine molecules attack organic contaminants in water.

Getting back to the well water, commonly occurring events in the environment can change the quality of well water on a daily basis. Heavy rains, a lack of rain, temperature and even air pressure can radically alter the nature of water pulled from well – and let us not forget about pollution from industry which can seep into the ground 100’s of miles away from a well and still, somehow, make its way into that water that well produces at some point.

So, Emma, in the end, and if you want to make the best possible decision regarding where you will get your drinking water, we suggest you have a sample of water drawn from the aquifer your proposed well will access and have it tested by a certified water testing laboratory such as National Testing Laboratories. Contact the well drilling company you think you may use to drill, if you go that route, and ask them for advice on getting sampling and testing done. Do make sure they submit the sample to a certified water lab, though, and not do the testing themselves!

Then contact the local water company and ask for a copy of their latest water quality report, usually referred to as a Consumer Confidence Report and abbreviated as CCR.

With both reports in hand, weigh the pros and cons of each and remember that no matter which option you choose, you may STILL want to consider having a Whole House Water Filter System installed and/or purchasing point-of-use water filter devices for the shower, faucet and countertop.

Question: What is EPA Limit for Trihalomethanes in Drinking Water?

Water Testing BlogChlorine, Chlorine Testing, Combined Chlorine, Disinfectant, Disinfection Byproducts, Free Chlorine, Haloacetic Acid, Max Contaminant Level, Sanitizer, THM, Total Chlorine, Trihalomethane, Water Quality Testing, Water Testing

We’d like to thank “Trinity” for asking the following question about trihalomethane levels in drinking water:

“In school we recently learned that chlorine added to drinking water by water treatment facilities reacts with organic contaminants in the water and forms harmful compounds called trihalomethanes. Does the EPA have a guidleine which limits the amount of trihalomethanes are considered safe?” — Trinity in Washington

First of all, we want to clarify something in Trinity’s question: Not all forms of chlorine added by water treatment facilities will cause trihalomethanes to form. Adding ‘free chlorine’ to water containing organinc contaminants will result in the formation of thrihalomethanes while adding ‘combined chlorine’, also referred to as chloramines, to water containing organic contaminants will not.

Unsure of the difference between free chlorine and total chlorine? The following Water Testing Blog postings will help:

Getting back to Trinity’s question, though, prior to 2004 the EPA set the maximum contaminant level (MCL) for trihalomethanes in drinking water at 100 parts per billion (ppb). In 2004 the EPA lowered the MCl for trihalomethanes in drinking water to 80 ppb. ( source )

THM’s May Affect Pregnant Women and Their Unborn Children

Not many people actually enjoy the taste or smell of chlorinated drinking water, but did you know that recent studies have unofficially linked birth defects to chlorinated drinking water? It seems as though a pregnant woman’s exposure to chlorine byproducts called trihalomethanes (THMs) in drinking water, bath water, etc. may play a part in causing serious health problems for her unborn child:

“Expectant mothers can expose themselves to the higher risk by drinking the water, swimming in chlorinated water, taking a bath or shower, or even by standing close to a boiling kettle, say researchers.

The finding, based on an analysis of nearly 400,000 infants, is the first that links by-products of water chlorination – chemicals known as trihalomethanes, or THMs – to three specific birth defects.

Exposure to high levels of THMs substantially increased the risk of holes in the heart, cleft palate and anencephalus, which results in the absence of a major portion of the brain, skull, and scalp.” ( source )

Most water systems chlorinate the water they provide in an effort to eliminate parasites and bacteria in drinking water which could lead to waterborne ailments and illnesses.

Not sure if your water contains THMs? Maybe the next few statements will help:

  • Public water supplies that use free chlorine as their primary disinfectant (instead of chloramines) may contain THMs. The compounds form when free chlorine molecules lock horns with a biological contaminant during the disinfection process.
  • Public water supplies that use chloramines as their primary disinfectant (instead of free chlorine) typically do not contain THMs. However it should be noted that these water systems do periodically ‘burn’ their water lines with free chlorine in an effort to get rid of any biofilm that has formed and THMs do result from those ‘burn’ sessions.

Still unsure as to whether or not your drinking water may contain THMs? You have three options:

  1. Call your local water authority and ask them if they use free chlorine as the primary disinfectant or chloramines. If so, then your water most likely contains chloramines.
  2. Have your water tested by a certified water testing professional.
  3. Use reliable drinking water test kits for both free chlorine AND total chlorine.

Acceptable TDS Meter Readings Do Not Guarantee Safe Drinking Water

Water Testing BlogChlorine, DBP, Disinfection Byproducts, Haloacetic Acid, Home Water Testing, TDS, THM, Trihalomethane, Water Quality Testing, Water Test Kit, Water Testing

In a recent article by Andrew Zeigler in Water Conditioning & Purification Magazine, we found the following statement intended for dealers of drinking water treatment systems which we certainly do agree with:

“Stop using the TDS (total dissolved solids) meter as the only measurement of water quality. Disinfection Byproducts like Trihalomethanes, Volatile Organic Compounds, METHYL tertiary-butyl ether, chlorine, chloramines, cysts and lead are the primary contaminants to Public Water Systems. They have no impact on the conductivity of the water. Yet these do not register on a TDS meter. And public water systems primarily supply from surface water that tends to have low TDS levels.” ( Water Conditioning & Purification Magazine, March 2009, page 42 )

While TDS does play a large part in the determining whether or not your water will leave deposits on your fixtures, it alone does not indicate the relative safety and purity of your water. As always Water Testing Blog suggests that people get their water tested by Certified Water Analysis Laboratories if they suspect a serious health risk.

For all other water testing needs, simple at home drinking water test kits used in conjunction with TDS meters ought to work just fine. you can find more information about home drinking water test kits on this page.

Tests Find Bottled Water No Cleaner Than Tap Water

What happened to the days when you could TRUST a company not to misrepresent a product they touted as ‘pure’?

Our opinion: Those days died with the dinosaurs or they never really existed!

Looking for ways to cut back in these tough economic times? An environmental group suggests skipping the bottled water and drinking from the tap. It might even be healthier.

The Environmental Working Group says its tests how 10 popular U.S. bottled water brands contain mixtures of 38 different pollutants, including bacteria, fertilizer, Tylenol and industrial chemicals, some at levels no better than tap water.

Wal-Mart’s Sam’s Choice at several locations contained contaminants exceeding California’s bottled water quality standards and safety levels for carcinogens under the state’s Safe Drinking Water and Toxic Enforcement Act, according to the group’s laboratory tests. Giant Foods’ Acadia brand consistently retained the high levels of cancer-causing chlorination byproducts found in the suburban Washington DC tap water from which it is made.

Overall, the group says the test results strongly indicate that the purity of bottled water cannot be trusted.

“It’s buyer beware with bottle water,” said Jane Houlihan, Vice President for Research at EWG. “The bottled water industry promotes its products as pure and healthy, but our tests show that pollutants in some popular brands match the levels found in some of the nation’s most polluted big city tap water systems. Consumers can’t trust that what’s in the bottle is anything more than processed, pricey tap water.”

“For years the bottled water industry has marketed their product with the message that it is somehow safer or purer than tap water,” said Wenonah Hauter, executive director of the non-profit consumer advocacy group Food & Water Watch. “This new report provides even more evidence that the purity of bottled water is nothing more than a myth propagated to trick consumers into paying thousands times more for a product than what it is actually worth.”

EWG said that laboratory tests it commissioned at one of the country’s leading water quality laboratories found 38 contaminants in ten brands of bottled water purchased from grocery stores and other retailers in nine states and the District of Columbia.

The pollutants identified include common urban wastewater pollutants like caffeine and pharmaceuticals, an array of cancer-causing byproducts from municipal tap water chlorination, heavy metals and minerals including arsenic and radioactive isotopes, fertilizer residue and a broad range of industrial chemicals. Four brands were also contaminated with bacteria.

Unlike tap water, where consumers are provided with test results every year, the bottled water industry does not disclose the results of any contaminant testing that it conducts, EWG said.

Americans paid $12 billion to drink 9 billion gallons of bottled water last year alone, EWG said. Yet, the tests show several bottled waters bore the chemical signature of standard municipal water treatment–a cocktail of fluoride, chlorine and other disinfectants whose proportions vary only slightly from plant to plant. In other words, some bottled water was chemically almost indistinguishable from tap water.

The only striking difference, the group says, is the price tag. The typical cost of a gallon of bottled water is $3.79–1,900 times the cost of a gallon of public tap water. (source article)

So what can YOU do to help make sure the water you consume does not contain harmful chemicals? Simple: Learn everything you can about the source your water comes from. If it comes from a bottle, read the bottle label and research the company that did the bottling. By law they must divulge the source of their water and you may find out that they merely take water from their own local (municipal) water supplier, run it through an activated carbon filter, bottle it, and ship it to you.

Choosing a Water Filter: Distiller

Water Testing BlogArsenic, Arsenic Test, Arsenic in Water, Copper, DBP, Disinfection Byproducts, HAA5, Haloacetic Acid, Home Water Testing, Lead, Metals, THM, Trihalomethane, Water Filter, Water Quality Testing, Water Test Kit, Water Testing

Today we will continue to explore the different drinking water filtration systems available to the general public by discussing briefly the specifics of a drinking water filtration system known as a Distiller.

  • One part of a distillation system boils drinking water into steam and a second part recondenses the ‘purified’ steam back into water.
  • Distillation systems may take the form of countertop models and point-of-entry (whole house) systems.
  • Distillation systems work quite well for people whose unfiltered/untreated drinking water contains heavy metals and elements such as copper, cadmium, chromium, lead, mercury, arsenic, selenium, barium, fluroide and sodium.
  • Some people opt to combine a distillation systems with an activated carbon system for more complete drinking water purification. Adding the activated carbon drinking water filter to the purification systems allows it to remove bad tastes and odors and a well-rated activated carbon filter will filter out many hazardous contaminants such as heavy metals, disinfection byproducts (i.e. haloacetic acids and trihalomethanes to name a few), chlorine, radon, volatile organic chemicals, parasites, and pesticides.

Many have asked the difference between the different types of drinking water filters they could use in their homes, at work, or at school.

Activated Carbon Filter:

  • Positively charged and highly absorbent carbon media in the filter attracts and traps many drinking water impurities.
  • You will typically find these drinking water filter systems on countertops, as point-of-use faucet filters, and under the sink.
  • A good system for eliminating bad tastes and odors and a well-rated activated carbon filter will filter out many hazardous contaminants such as heavy metals, disinfection byproducts (i.e. haloacetic acids and trihalomethanes to name a few), chlorine, radon, volatile organic chemicals, parasites, and pesticides.

Drinking Water Filters: Why Install a Reverse Osmosis Water Filter?

Why Install a Reverse Osmosis Water Filter?

Many of our readers have asked questions about reverse osmosis drinking water filtration systems and want to know more about them. Hence the purpose and reason for this deviation from the normal subject matter in this Water Testing Blog entry.

“Today, people are increasingly concerned about the quality of the water that they consume. Under the best of conditions, it’s possible that water may contain hazardous contaminants, ranging from dissolved organic and inorganic materials, to suspended particles and microorganisms. If you live in a home with older pipes, you may also be exposed to lead in your water. Even the chemicals, like chlorine and fluoride, that many municipalities add to water to kill bacteria or to fight tooth decay may be harmful to humans. If such chemicals are not used, your water could be harboring deadly parasites. If you suspect your water may contain microorganisms, lead, or other contaminants, have your water tested.

To decrease their exposure to possible contaminants, many people drink and cook with bottled water or put distillers or disposable cartridge filters on their water supply lines and faucets. However, bottled water may not be any purer than the water taken from your faucet, distilled water requires boiling and tastes flat, and although charcoal filters improve the taste and remove odors from water, they do little to remove chemical contaminants and microorganisms. If you find your water is contaminated, choose the correct water filtration system to correct the problem.

Reverse osmosis (RO) is generally recognized as the best system for purifying water while retaining good taste. The EPA recommends reverse osmosis filters for microbiologically safe water. Yet, an RO system alone will still allow certain waterborne germs to pass through. To knock out these types of contaminates, most RO systems incorporate some additional type of filtering, usually a replaceable carbon post filter. ( source )”

Testing for Bromates

Water Testing BlogBottled Water, Bromine, DBP, Disinfection Byproducts, Water Quality Testing, Water Test Kit, Water Testing

At this time the staff of Water Testing Blog does not know of a simple testing method for bromates. This does not mean companies who bottle water cannot have their product(s) tested for bromates.

“MWH Labs has received accreditation for testing of bromate by EPA Method 317 under the Stage 2 Disinfection/Disinfection Byproducts (DDBP) Rule. Method 317 is, a very accurate and very precise analytical method for bromate, that avoids many of the problems with false negatives and false positives that are associated with the existing analytical method (EPA 300.1). Additionally method 317 is capable of detecting bromate as low as 1 ppb (vs 5 ppb for method 300.1), helping clients to more accurately assess their bromate treatment options. Bromate is regulated in bottled water and potable water at a level of 10 ppb.”(source)
