City Employee Gets Probation for Falsifying Water Test Results

Water Testing Blog — Fri, 03 Sep 2010 13:03:44 +0000

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.

6-Stage Inline Filter for Arsenic

Water Testing Blog — Wed, 04 Aug 2010 23:56:26 +0000

This multi-stage (six) inline filter does a lot more than just remove arsenic from water at a rate of up to 1 gallon per minute, a rate perfect for use with water fountains, bottleless water coolers, commercial coffeemakers, and ice machines. It uses all six of its filtration layers to effectively remove a number of drinking water contaminants.

In stages 1 and 6 water flows through pre and post one – micron filters capable of removing suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other types of unwanted matter.
In stage 2 water flows through a specially engineered arsenic removal/reduction media.
In stages 3 and 4 water flows through a media bed comprised of high purity KDF-55D ®, and KDF-85D ®, which operate using electrochemical and spontaneous oxidation/reduction (REDOX) principles. The combination of these two special media completely oxidizes any chlorine in the water.

As an added bonus, heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals also get removed/reduced during this stage of filtration.

While some KDF media beds can harbor unwanted bacteria, studies have shown that this particular unit reduces the likelihood of bacteria growth by as much as 90%, thus eliminating the need for silver, an element considered by some to pose health risks.

Worried about the possible addition of copper or zinc to the water in any significant amount? On a sample of water containing 2.3 ppm chlorinated water, testing after filtration detected <0.05 mg/l copper and only 0.46 mg/l zinc. The EPA has set the aesthetic levels for copper at 1.0 mg/l and 5.0 mg/l for zinc. Additionally, the human body requires both zinc and copper for good health. The FDA recommends a daily intake of 15 mg of zinc and 2 mg of copper.
In the fifth stage of filtration, water flows through granulated activated carbon (GAC) which adsorbs a wide variety of organic contaminants, such as any remaining chlorine (99.9%), chemicals linked to cancer such as Trihalomethanes and benzene, pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and a laundry list of other chemical contaminants that may exist in your source (i.e. tap or well) water.

What about replacement filters? Will I have difficulty finding them? Highly unlikely! The manufacturer of this inline arsenic filter, Crystal Quest has existed in one form or another in the commercial water purification industry for more than thirty years.

You can order replacement filters for the inline arsenic filter on FilterWater.Com, a leading online vendor of water quality improvement products from Crystal Quest and other manufacturers.

How do you know if you need a water filter?

The answer, quite simply, involves testing your water. You can either test it yourself using a home water testing kit like the Water Quality Test Kit from SenSafe… or you can have a certified water testing laboratory such as National Testing Labs analyze your water.

In cases where homeowners suspect contamination, we always suggest using a certified water testing lab. Better to play it safe than sorry because… It’s your water, your health… and your LIFE!

Water Filter to Remove Tannins

Water Testing Blog — Tue, 20 Jul 2010 13:03:33 +0000

The presence of tannins in drinking water can give water a “tangy or tart aftertaste. Some people have also attributed a musty or earthy odor in their water to tannins.” Also, “They normally have a faint yellow to tea-like color, and can cause yellow staining on fabrics, fixtures, china and laundry.” ( source )

For the reasons mentioned above, and possibly a wide range of others, most people would prefer their drinking water not contain tannins. If you find yourself in that category of people, then the whole house water filter for tannin removal ought to pique your interest.

In the first stage water travels through a 20″ sediment cartridge designed to remove sediment, silt, sand and dirt… an action which helps to extend the life of water softeners/filters and helps to prevent damage to control valves and pumps.

In the second stage, water travels through a 1.5 (or 2.0) cubic foot Tannin reducing mineral tank controlled by an Automatic Microprocessor Control valve which regulates the amount of time water spends in the tannin reducing tank. The longer time the water spends in contact with the special ion exchange media, the more effectively the media works to remove naturally occurring organics and organo-metallic complexes

In the third and final stage of filtration water travels through a 20″ solid carbon cartridge designed to remove volatile organic carbon compounds (VOC’s), insecticides, pesticides and industrial solvents.

Maximum Removal Capacities: 5ppm Tannins and 40 grains hardness
Maximum Iron and Manganese Levels: Combined Manganese and Iron levels must be below 0.2ppm (test for total iron, test for manganese)
Filter Life: 1.5 cu.ft – 5-7 years, 2 cu.ft – 7-8 years
Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the F.D.A.
Solid 316-Stainless Steel Tank
Stainless Steel Bypass Valve
10 Year Warranty on Resin Tank and Brine Tank Assembly
5 Year Warranty on All Computer Monitored Control Valves

Water Filter to Remove VOC’s, Oils and Hydrocarbons

Water Testing Blog — Mon, 05 Jul 2010 19:08:07 +0000

With all the talk about oil washing up on the shores as a result of the BP oil platform disaster, some people have started to ask a very smart question:

Could some of that oil somehow end up in my well water if I live close to the shore?

At this point no one can answer that question definitively, but rest assured plenty of people would prefer to err on the side of caution and have a water filter system capable of removing any trace elements of the BP disaster that may find their way into their water supply.

The Crystal Quest Mega Triple Undersink Water Filter, known by manufacturer’s part number CQE-US-00309 and good for proper filtering of up to 10,000 gallons of drinking water, uses a combination of three separate filter chambers:

Water flows through a sediment filter cartridge that removes sediment, silt, sand and dirt. This helps to extend the life of water softener and water filters and prevent damage to control valves and/or pumps.
In the second filter chamber, water flows through pre one – micron filter pads which remove suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.

It then flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals — copper and zinc (Eagle Redox Alloy® 6500 and Eagle Redox Alloy® 9500) — that works using electro-chemical and spontaneous-oxidation-reduction (REDOX) principles. At this stage chlorine gets instantaneously and almost inexhaustibly oxidized iron and hydrogen sulfide get oxidized into insoluble matter which attaches to the filter media, heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals also get removed by the electrochemical process.

In the next stage, water flows through the ion exchange resin, further reducing heavy metals such as lead, copper, aluminum, and water hardness.

Next, water passes through granulated activated carbon (GAC), a compound universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants such as chlorine (99.9%), chemicals linked to cancer such as THM’s and benzine, pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and hundreds of other chemical contaminants potentially found in drinking water. It also works to greatly reduce and/or eliminate bad taste and odors in drinking water.

The last section of this filter chamber contains another one-micron filtration pad for further reduction of undesirable particles.
In the third filtration chamber water travel through a solid carbon cartridge designed to remove remaining volatile organic carbon compounds (VOC’s), insecticides, pesticides and industrial solvents.

Province to Pay for Well Water Testing — Winnipeg

Water Testing Blog — Wed, 02 Jun 2010 23:28:14 +0000

Once again flooding has potentially contaminated private wells, and this time it happened up in the province of Winnipeg in Canada where government officials recently announced that the Province would pick the tab for well water testing.

Although we hate to hear about areas getting flooded out, we do love to read about governments stepping in to assist victims with making sure they have safe, clean drinking water once the flood waters have gone down.

The provincial government is encouraging people with wells in flood-affected areas to get them tested once flood waters recede.

Officials said the province will cover the full costs of testing.

The province normally subsidizes well-water testing but the well owner’s share is now also being waived for the month of June for flooded areas, said officials.

Manitoba Water Stewardship is also recommending that people with wells in flooded areas boil their water or use alternatives such as bottled water until test results confirm the bacterial safety of their water.

Water samples should be marked 2010 Flood and sent to Maxxam Analytics, Unit D, 675 Berry St., Winnipeg, MB R3H 1A7. More information is also available by calling 204-772-7276 or 1-800-665-8566 (toll-free). ( source )

As a general rule victims of flooding whose wells may have gotten contaminated should, at the very least, test their wells for bacteria, nitrates/nitrites, heavy metals (i.e. copper, lead and iron) and pesticides. Individual situations may merit additional and/or repeated testing.

Interested in having a certified water testing lab take a look at your drinking and/or well water? National testing Laboratories has several different levels of testing available to the general public for reasonable rates.

Pesticides in Children Linked to Increased Risk of ADHD Diagnosis

Water Testing Blog — Tue, 18 May 2010 23:32:55 +0000

Pretty much everyone we have ever met KNOWS that a chemical compound designed to kill creatures of even the smallest size could possibly have adverse effects on human beings. More to the point, though, a recent study of 1,139 children ranging in age from 8 to 15 years old found a definite link between the concentration of pesticide ‘markers’ in the children and the existence of ADHD or other behavioral problems.

We expect that the data generated by this study will definitely raise more than a few eyebrows and add fuel to the fire already burning regarding the topic of pesticide and herbicide use in the United States.

Exposure to pesticides used on common kid-friendly foods — including frozen blueberries, fresh strawberries and celery — appears to boost the chances that children will be diagnosed with attention deficit hyperactivity disorder, or ADHD, new research shows.

Youngsters with high levels of pesticide residue in their urine, particularly from widely used types of insecticide such as malathion, were more likely to have ADHD, the behavior disorder that often disrupts school and social life, scientists in the United States and Canada found.

Kids with higher-than-average levels of one pesticide marker were nearly twice as likely to be diagnosed with ADHD as children who showed no traces of the poison. ( source )

Several of us on the Water Testing Blog staff have small children and it saddens us to learn that supposedly ‘safe’, also known as ‘better than giving them candy or chips’, types of snacks may fall into the category of foods that may contain the toxins mentioned in the article.

In the end…

…we will start washing even the frozen fruits and, of course, testing our drinking water. If the government and big business can’t even keep toxins off of our supposedly safe foods, should we REALLY trust them to keep contaminants out of our drinking water?
