To the untrained eye each ‘glowing’ report tells a wonderful water quality success story and most of the reports use pristine pictures of crisp, clean water flowing beautifully from a sparkling faucet to paint a picture of water quality perfection.

We congratulate every water department that passed Federal muster and thank them for doing a fine job.

We scold every water department that failed Federal muster. Please get your acts together and do a better job this year!

The problem with annual water quality reports

In a good number of the reports we have looked through we found a rather ugly truth buried in the tables, charts, and pretty pictures: Yes, the water tested below Federal Guidelines for potentially hazardous metals like lead, chromium, etc. and disinfection byproducts (DBP’s), but detectable levels of those drinking water contaminants existed in the water.

Health officials have stated for a long time that ANY amounts of toxic metals like lead in drinking water or chromium may cause serious health problems — especially in young children. Exposure to metals like lead may lead to lower IQ’s, developmental problems, behavioral issues, and impaired learning abilities.

Oh, and one more thing: When last we checked, the medical community agrees that any concentration of lead in drinking water constitutes an unsafe concentration of lead in drinking water.

Why are Federal Guideline concentrations higher than medically ‘safe’ concentrations?

The United States Environmental Protection Agency set the maximum allowable contaminant concentration levels for most unwanted drinking water contaminants… a long time ago. In some cases the levels for some contaminants may have hit the books more than 50 years ago!

One must also remember that regardless of the toxicity of a drinking water contaminant, the number of potential drinking water contaminants that the USEPA has to keep tabs on grows by leaps and bounds each year. We imagine that a case load of that magnitude would result in a standard operation procedure based on the following principle: Squeaky Wheel Gets the Oil.

Contaminants making the news and/or waves in the health community probably get the bulk of attention, laboratory time, and financial resources while research and legislation on other, less newsworthy (but no less dangerous!) drinking water contaminants get put on the back burner.

Moral of the story?

As with anything in life, you should take your local water department’s Annual Water Quality Report with a grain of salt. Read through the data and verify for yourself that when your water leaves the treatment facility it contains NONE of the drinking water contaminants that you hear about on the news or that you find in the EPA’s Primary Drinking Water Standards List — especially if you have small children in the house.

When setting MCL’s (maximum contaminant levels) for drinking water contaminants, the weight of a person gets factored into the equation and health officials typically set MCL’s using the weight of an average sized adult, not a child.

Chicago’s first round of testing for a toxic metal called hexavalent chromium found that levels in local drinking water are more than 11 times higher than a health standard California adopted last month.

But it could take years before anything is done about chromium contamination in Chicago and scores of other cities, in part because industrial polluters and municipal water utilities are lobbying to block or delay the Obama administration’s move toward national regulations. ( source )

As some of you may recall, we wrote about chromium showing up in drinking water in the past and from the sounds of things we will very likely find ourselves writing about it many more times.

The discovery of hexavalent chromium in drinking water is renewing a debate about dozens of unregulated substances that are showing up in water supplies nationwide. Potential health threats from many of the industrial chemicals, pharmaceutical drugs and herbicides still are being studied, but researchers say there is strong evidence that years of exposure to chromium-contaminated water can cause stomach cancer.

Test results obtained by the Tribune show that treated Lake Michigan water pumped to 7 million people in Chicago and its suburbs contains up to 0.23 parts per billion of the toxic metal, well above an amount that researchers say could increase the long-term risk of cancer. ( source )

For those of you not familiar with the articles previously written about chromium in drinking water on this site, the following links will really come in handy:

• Chromium in Drinking Water
• Chromium in Drinking Water Information
• Specifics From EWG’s Report on Chromium in Drinking Water
• Meter to Test Chromium in Water

We have written more, but the ones above ought to give you a pretty good understanding of the chromium in drinking water situation facing many areas of the United States. Water supplies previously deemed ‘safe’, and we include both municipal and private water supplies in this statement, have come under new scrutiny and many do not measure up to the current quality standards.

Speaking of tests, can the average person test for chromium in drinking water? Of course they can — but as always the best testing solution comes in the form of analysis by a certified water testing laboratory.

If, however, you would like a fast and easy method to test for the presence of chromium in water, you will definitely want to take a look at the chromium test strips produced by SenSafe. They make field testing for hexavalent chromium in water a simple and inexpensive process.

We think that will change now that the Environmental Working Group (EWG) has released the findings of recent tests performed on municipal water supplies around the United States.

The Environmental Working Group (EWG) released a report today stating that at least 31 U.S. cities have tap water that is contaminated with a dangerous chemical known as chromium-6.

…

According to the Environmental Working Group, chromium-6 is technically deemed cancerous if inhaled. However, the EWG are investigating the extent to which chromium-6 is cancerous when ingested. Water supplies are usually contaminated with chromium-6 by eroding steel and metal plating facilities.

Rebecca Sutton, a senior scientist with EWG and lead author of the study, explained to CNN that there are a significant amount of documented studies showing a positive correlation between contact with chromium-6 and an increased risk of stomach cancer in humans.

As stated in EWG’s report, “Studies in both animals and people show that exposure to [chromium-6] via drinking water leads to elevated chromium levels in tissues, particularly the gastrointestinal tract, blood, liver, kidneys and spleen, and in increased toxicity.”

Opting for bottled water isn’t necessarily a safer choice either because it isn’t guaranteed that there aren’t traces of chromium-6 in it. “There is no legal limit for [chromium-6] in bottled water either, so consumers cannot assume it is free of the contaminant,” stated in the report.

Sutton recommends investing in a quality water filter to protect yourself.

The cities with the highest level of chromium-6 in their tap water are Norman, Oklahoma; Honolulu, Hawaii; and Riverside, California. ( source )

We often get email from ‘unhappy’ readers who claim we exaggerate points and repeat ourselves ourselves ourselves. Oh, well we prefer to think of it as stressing important points and emphasizing them by means of repeated exposure because sometimes a message just doesn’t get fully understood the first time a person hears it.

As an example, no matter how many times we tell people they have ultimate responsibility for the quality of their drinking water, a good number of people STILL think some agency in the government goes around testing tap water at private citizens’ homes as a courtesy and warns citizens when their water contains unwanted contaminants that entered the water supply after it left a water treatment facility.

Let us say again that no such branch or division of State, Local or Federal Government exists!

On occasion a water department worker MAY test the water coming out of fire hydrants in your neighborhood but they will not knock on your door and ask if you’d like a free municipal water test. If you want to know what the water at YOUR house or place of business contains, YOU will have to test it or have it tested.

OK, well how do I test for chromium in tap water?

Easiest method for chromium testing: Chromium test strips manufactured by SenSafe detect Chromium (VI) levels down to 0.1 ppm (mg/L).

Water Metals Test Kit

Ordinarily when a water treatment facility’s product tests positive for too great a concentration of a heavy metal such as lead, copper, iron, mercury, etc. all sorts of people — especially environmental watchdog groups — lay the blame on the doorstep of the water treatment facility.

But not this time. Environmental Working Group (EWG), a lobbying group hailing from Washington, D.C., regards the finding of hexavalent chromium in several public water supplies as a problem, yes, but not necessarily all the fault of local water treatment facilities.

Instead, EWG would like for people to place the blame with the sources of chromium contamination.

Makes perfectly good sense to us. Stopping the flow of pollutants from entering the water supply sure would take a lot of the burden off of water treatment plants and ultimately off of the end user… AKA: All of us in the general public.

A Washington D.C. based environmental group says it’s not trying to put blame on local cities for contamination of hexavalent chromium. A single sample taken an Avion Water Company customer’s tap was one of 35 taken across the country that showed levels in excess of what the State of California is proposing as a public health standard. “This is an upstream pollution problem that needs to be stopped at the source. We need better water source protection and while we do advocate all utilities do their own testing for this and let their all their customers know the results, this doesn’t mean that they’re the ones responsible for the pollution.”

Leanne Brown with the Environmental Working Group says the only consumer level filtering system that can remove this chemical is a reverse osmosis system. Hexavalent chromium can come from manufacturing, pulp mills, and leather tanning. ( source )

So where does that leave average people like us? In the exact same place as before this result… in charge of making sure we have safe, clean drinking water going into our glasses.

Obviously a problem with chromium-6 pollution exists in this country and we, as end users, will not know whether or not we personally have chromium-6 (hexavalent chromium) in our own water supplies unless we perform testing on a periodic basis.

How to test for chromium-6 (hexavalent chromium) in your water

As usual, nothing beats laboratory testing of your water by a certified water testing laboratory (i.e. National Testing Labs)… but that does not mean each and every test needs to get shipped off to a lab.

Periodic testing for chromium-6 using at-home drinking water test kits between annual (or more frequent) lab testing provides continual piece of mind and does not cost a fortune.

SenSafe manufactures a simple dip-n-read test strip for hexavalent chromium (chromium-6) that provides results in under 2 minutes… and 50 tests costs somewhere in the neighborhood of around $14.00 (about $0.28 per test!).

Detection Levels for the SenSafe product: 0.1, 0.25, 0.5, 1, 2.5, 5, 10, 25, 50 mg/L (parts per million).

If we found one metal, might there be more?

No one can answer that question honestly… without conducting additional testing. A home or business owner might assume that the presence of chromium or other heavy metals such as lead, mercury, etc. also exist in their water supply, but as we said, without additional testing no one will know for sure.

A good way to test for metals commonly found in drinking water?

If you want a fast and inexpensive testing method for metals in drinking water that will tell you if you have a dissolved metals concentration greater than 10 parts per billion in your water, take a look at the Water Metals Check Test Strips.

While this product will not tell you exactly WHICH metal(s) your water contains, it will allow you to quickly and easily determine whether or not you will want to opt for other, more ion specific testing.
