A naturally occurring reddish metal that appears in rock, water, soil, sediment and in the air, copper has unique physical properties which make it perhaps one of the most commonly used and important metals. You can find copper in pennies, as part of electrical wiring systems, and in plumbing. You can also find it used in some pesticides and algaecides.

As humans we require a minute amount of copper to live, but as with anything, too much copper in a short period of time and prolonged exposure to excess copper can have detrimental effects on our health.

For that reason health officials suggest testing your drinking water for copper, and other things obviously, on a semi-regular basis… especially if you live in an older home, in an area that has older water delivery lines, or if you have well water.

How can you test for copper?

Previously you would have to use a test kit that used drops, tablets, powders, etc. or have your water tested by a water testing laboratory. As usual we suggest that people use water testing labs if they have serious reason to suspect drinking water contamination and that owners of wells have their water tested by a certified water testing lab at least once a year, for occasional testing needs you can use copper test strips such as the John’s Copper product manufactured by SenSafe.

If you think you may have a need to test your water for copper, then you may also want to test for other metals such as iron, manganese, mercury, and lead.

A test kit such as the Well Driller Master Test Kit has all those tests and more.

Whether listed by the United States Environmental Protection Agency as a serious health concern or just a general nuisance, most people care about only one thing: Testing for metals in drinking water and removing them ASAP!

Why the Concern Over Metals in Water?

Health officials unanimously agree that excessive exposure to dissolved metals in water can in many cases lead to serious side effects such as cancer, organ damage, impairment of the nervous system, the development of a life-threatening condition where the immune system attacks its own cells, a reduction in the growth and development of cells, joint problems/diseases, circulatory system problems, and last, but definitely not least… death.

Younger people stand to suffer the effects of exposure to metals more than adults do to their small body masses. In other words, an 8 oz glass of water containing X ppm (parts per million) of heavy metals will result in a much higher dose in a child than it will in an adult who drinks the same glass of water.

Some health officials theorize that very young children and unborn babies whose bodies develop at a rapid pace absorb the metals readily into their systems. Exposure of this nature often results in learning difficulties, damaged nervous systems, memory deficiencies, and even behavioral problems such as hyperactivity and aggressiveness.

* The Pool Check^TM Copper test strips offer fast, accurate test results for copper, pH and alkalinity at a reasonable cost.

* The Pool Check^TM Pro Metals test strips offer fast, accurate semiquantitative test results for ‘all’ metals at once. It does not specify which metal(s) it detects, but it does give pool owners a better idea of how much staining potential their pool water has.

* The eXact^R Micro 7 pool and spa testing meter tests for many parameters including iron and copper.

* Other testing methods include using ‘wet’ chemistry kits from companies like Lamotte and Taylor, but they typically involve slightly more advanced testing techniques such as titrations. Wet kits also make use of messy dpd liquids, difficult to dissolve dpd tablets, and awkward dpd powder pillows.

For those who suspect that their source water contains metals, the SenSafe^TM Metals Check test strip will work quite well. It detects the metals commonly found in tap water and well water and provides accurate metals testing results in under 3 minutes.

Can Metals Stains in Pools be Removed?

For the most part, yes. The task will take effort, though, in some cases.

Vinyl liners typically resist staining quite well but the stains that do set in will not come off without a fight. Pool owners must use sequestering compounds and/or chelating compounds which attach themselves to the metal stains/deposits and more or less pull them back into solution. (See Jack’s Magic)

Owners of concrete and gunite pools suffer even worse fates when it comes to metals staining. Typically they must wash the stains away using diluted muriatic acid — and in some cases that means draining the pool completely before they can begin.

Due to the annoyance, expense and inconvenience associated with the removal of metals stains from pool liners and plastic fixtures, swimming pool professionals recommend testing for metals on a regular basis if the pool has a heater, uses a copper or silver ionizer, or has recently had water added to it that may have contained dissolved metals.

In unbalanced water, copper may ‘drop out of solution’ and cause staining of a pool’s submerged fixtures and pretty much all of its non-metal surfaces (i.e. vinyl liner, fiberglass bottom, concrete/gunite bottom, etc.). Typically a severe drop in alkalinity and/or pH can result in copper staining with the right amount of free dissolved copper present.

In the case where the pool in question has a heater tests for copper in pool water yielding positive results may mean the pool water has become corrosive and has started to eat away at the copper in the heating element(s) in their heater.

A second source of copper, and also a good reason to test for copper in pool water every once in a while, has to do with the pool owner’s choice of algaecides. Some of the algaecides on the market contain trace amounts of copper due to copper’s ability to effectively fend off an outbreak of algae in water whose chlorine or other oxidizer level has dropped. Long-term use, or most often improper overuse, of copper-based algaecides can lead to an excessive buildup of copper in the water. A severe change in alkalinity and pH, possibly as a result of a rainstorm or the addition of ‘new’ water to the pool, may cause that copper to ‘come out of solution’ and cause staining on the surfaces mentioned earlier.

Does Copper in Pool Water Always Mean Trouble?

Absolutely not! In fact, some pools rely on copper as their primary algistat and use very low levels of oxidizers such as chlorine to destroy any organics that do attempt to make the water their new home.

How Can Pool Owners Test for Copper in Pool Water?

Pool owners can test for the presence of free dissolved copper in their pool water using traditional wet kits, by taking a sample of their pool water into their local pool store for analysis, or by using a test strip such as the Pool Check^TM Copper test strip which detects free dissolved copper levels as low as 0.2ppm and as high as 2.0ppm in under a minute.

The Pool Check^TM Copper test strip also tests for pH and Alkalinity at the same time it tests for free dissolved copper residual. This product tests for pH and Alkalinity because they changes in those two pool water parameters can cause free dissolved copper to come out of solution, settle on surfaces, and stain whatever it lands on — sometimes permanently!

What metals could do all that?  Scientists debate that question quite often, but the point of the matter is that you don’t want ANY of the metals, debated or otherwise, in your water.

Sources of Metal Contamination in Drinking Water:

Metals find their way into your water supply in a number of ways.  While the water may have left its source (well, city reservoir, etc.) w/o metals in it, the instant it touched ANY metal it automatically picked up some ions — especially if the water had an unusually high or low pH for any reason.

Even if you think your house has all (new) PVC fittings and piping, keep in mind that your water provider does not use PVC piping to run the water from itself to your doorstep.  Oh, and those metal fittings called ‘faucets’ and the screens inside them contain metal as well. (reference)

So as you can see, consumers ought to consider doing a general test for metal ions their drinking water.  Critters such as aluminum, lead, cadmium and so forth can pop up from a number of sources and according to the United States Environmental Protection Agency and Health Professionals worldwide, people need to limit the amounts of metals they ingest.

Simple Test for Metals in Water:

Just a few short years ago consumers had to rely upon the ‘wisdom’ and ‘training’ of water system consultants (salesmen!) to tell them if they had metals in their drinking water. . . or they could shell out some serious dough and send their water off to a local lab for a complete and thorough analysis — which would tell them more information than they needed, yet probably wouldn’t tell them anything they could use to decide if they had problems with their water.

Thankfully those days have come to an end.  Consumers now have the option of testing their own drinking water for metals at a cost they can afford, and with an amount of ease they can tolerate.  A simple dip-n-read test strip for metals in water that detects levels as low as 10 ppb (typically reverse osmosis water is at this level or lower) and as high as 1,000 ppb (1 ppm) is readily available from a number of vendors.

While SenSafe(TM) Water Metals Check will not tell you specifically what metals your water contains, it will let you know that you may have a reason to have your water looked at by a water industry professional.
