Copper (Cu) in Tap Water
A technical paper by Olympian Water Testing specialists
Copper in Drinking Water
Copper is a mineral found in the earth and rocks that’s one of the essential trace elements [1]. Because copper pipes are found everywhere in plumbing, eventually the copper will corrode and enter the water supply in the home in quantities that can be hazardous to the water quality. So, too, will new copper plumbing that has not had a chance to acquire a mineral coating inside the plumbing system, spilling potentially unnecessarily high copper levels into the public water supply.
What we want you to know — in the most detail — about copper, whether corrosion or freshness impacts your water, and how you can avoid harming your health is our education mission.
How Copper Gets into Water
There’s no copper at all in any water sources. So where does the high copper come from?
The most common reason why drinking water has high copper levels is because it’s usually water that has been drained through copper pipes for a while, and that copper can build up to significant levels if left to sit overnight. So, copper is water mostly from the household taps, pipes, and old water heater [2]. Fortunately, this can be rectified with a simple as flushing the water for a few minutes. But copper may leach into the water from industrial effluent, copper-bearing rocks, and mining effluent.
Also, more copper in acidic and carbonated drinks can contact copper bottles, fittings and tubing. These drinks have a carbon dioxide, which will rust the bottle or the pipe, so this mineral goes in these drinks [3].
Foodservice establishments usually need to add a backflow control device or assembly to their carbonated drinks dispensers to avoid carbon dioxide contacting copper [4].
How Else Can You Be Exposed to Copper?
Copper’s Potential Health Benefits in Water Consumption.
But besides copper in the water you can get exposed to copper in other ways.
Drinking it from the air and touching copper-containing products [5].
Ingesting copper sulfate crystals. They are cheap, people have stolen them imagining it is candy [5].
Exposed to copper dust in your office or neighbourhoods where copper is mined, used in agricultural and other uses [5].
Copper is also found in nuts, avocados and wheat germ [6]. So if we have people at high risk, such as those with Wilson’s disease, this could be caused by eating these fruits.
Health Effects of Copper on the Body
A typical adult should get 2-3 milligrams of copper every day, the National Academy of Science tells us. Up to 9% of this comes from your food, and less than 10% of it comes from drinking water [7].
There is research that shows that water is a major source of 4–45% of your copper requirement [8]. That’s because the body excretes about half the copper you ingest, which keeps the body from getting copper poisoned. Although copper is found all over the body, it’s concentrated in the liver and kidneys. So it is not surprising that liver and kidney dysfunction are among the main complications of copper toxicity [3, 8].
Voici les signes that show copper high consumption: [8];
Gastric issues
Headache
Diarrhea
Nausea and vomiting
Drinking water containing more than 1300 micrograms of copper per liter will harm everyone in the long run, leading to kidney disease, liver disease and even death.
The smell of copper mists, dust and crystals can damage you as it can sting the nose and throat. It also causes headaches and vertigo. The effects unfortunately can be fatal in the extreme [3].
Keep in mind that infants and people with Menken’s and Wilson’s disease are sensitive and can be very seriously poisoned by copper as their bodies don’t easily break down copper [9]. Wilson’s disease, a genetic condition wherein the enzyme that processes copper becomes deficient or malfunctioning, and copper builds up in the liver, brain, corneas, kidneys and heart [10].
Babies can be given high copper content of breast milk – so the baby will develop the same symptoms as an adult exposed to high copper concentration in water or air.
Can Copper Cause Cancer?
The US Department of Health and Human Services would have to check copper for carcinogenicity before it could say if copper is carcinogenic. But so far there is no proof that copper causes cancer. Other relevant authorities, like the US Environmental Protection Agency or International Agency for Research on Cancer have not evaluated or identified copper as a carcinogenic mineral, mostly because there is no evidence and no research [11].
Is it Possible to Get Medical Tests to Check for Copper?
Yes. Some testing water companies measure copper in body fluids such as urine and blood and body tissues such hair and nails. You must visit your healthcare provider so that he/she can inform you if you should have a test and what kind of test would be best for you.
These measurements will tell you if you have been exposed to copper at all or if your body has problems regulating it. These tests aren’t like the usual tests you get at the doctors office, and can’t predict disease. If you have come in contact with copper, consult a nurse or doctor or dial poison control.
How to Tell if Copper Levels are Elevated in Your Drinking Water
Copper pipes over time form a natural film to avoid being washed away. But it’s probably not practical for plumbing under three years of age since it’s usually not time to form this coating [12].
Bitter Tasting Water
The usual effect of normal copper concentration in the water is green/blue staining on hand basins, taps, pipes, toilets and showers. Yet high copper concentrations will make water metallic or sour [13]. If your water is not tasting right, you have a contaminated water. -Then stop drinking the water and reach out to a professional water testing service for an inspection.
Is there a Way to Reduce Copper Levels in the Water?
In the home, the quickest way to lower copper in water is to run the water for 30 seconds or flush the toilet. Let the water run and put it in a bucket to water your plants in the garden. Then, you can go for drinking water water filters.
Lead and Copper Sampling
Copper and lead in water (both in municipal water systems and in wells) — community and permanent non-community water systems must monitor copper and lead according to state regulations [14]. Specimen for such tests must be from all points of use on the property and two draws from cold lines per fixture is the minimum. They even probe hot water lines for data nits.
As lead and copper are not present in source water, professional sampling can tell you if the pipes are conveying corrosive water and can give you data and guidance on how to best clean it.
Water samples that show you have too much copper in your water on a flush sample tell you that you have to overhaul the system extensively.
Home Water Treatment
In the US, the majority of people do not need to install water treatment to save them. But if you discover that the water you’re drinking is bad, or you’re not happy with its colour, smell or taste, you can get your water tested and treated if necessary.
Water treatment steps to take
How Copper Enters Drinking Water
The Source of Drinking Water
If you drink a public water system, then the health department probably regularly tests the water for contaminants to meet Safe Drinking Water Act guidelines [15, 16]. You can read more about the quality of your city water system drinking water in the Consumer Confidence Report [15]. Vous pouvez also retrieve this report from your tool.
In the case of a private well, then you’ll be more personally responsible for keeping the water safe to bathe, cook with and drink. Moreover, you will need to hire a water testing company for frequent water quality test.
The Reasons Why You might Need Water Treatment.
No one wants their water tested for the same reasons. Hence it is important to know why you need water treatment. These are just some reasons:
Worry about a particular lead, copper, arsenic or nitrate pollutant?
Water that feels, tastes or smells strange.
Water that has sediment or is cloudy.
It also indicates issues with copper and/or other heavy metals above the recommended levels.Expert testing shows problems with copper and/or other heavy metals above the acceptable limits.
Select Your Water Treatment Option
There are different kinds of water treatment depending on the purpose of the water treatment.
Osmosis Water Filter
With copper, you’re best bet is a reverse osmosis water filter. Reverse osmosis removes 97-98% of copper from the water [17].
There is a tank, membrane and faucet to the reverse osmosis system. Typical installation: the membrane is mounted together under the sink and the faucet is installed on top. In contrast, the tank stores treated water and can be located under the sink, where you enter the house, or is an independent countertop unit. This technology uses semi-permeable membrane to wash out ions, molecules and particles as the water flows [17, 18]. Hence such a device will repel copper ions over a semi-permeable membrane while water molecules are able to flow through.
Distillation
Distillation is another great water treatment technology because it can remove up to 99 % of all contaminants including copper [17]. The steam goes through a screen, and the copper goes into it. Filtered steam returns to water, which is dumped into a tank. The tank water is chilled and can now be pumped out.
: Keep in mind that distillation may not be as easy to install as reverse osmosis systems since it boils. Water is too slow to boil so only treat a small quantity in one go.
So, this would be the best for someone who has a lot of time, doesn’t use a lot of water, and is tidy. It will be also a good value proposition.
Ion Exchange Water Softeners
Water softeners with ion exchange strip up to 95 per cent of copper from the water [17]. Such softeners make use of resin beds, which syphon metal ions such as copper with negative ions through a process called ion exchange [17, 19]. They renew the beds of resins by flushing the softener with saltwater.
Acid Neutralizers
Acid neutralizers can even remove copper from water. Generally the most widely used type of acid neutralizer is lime-soda ash system that removes up to 65% copper from water [17]. So this isn’t necessarily for you if you need to get rid of a lot of copper. But maybe it is good for you if you live in a well and want to use neutral water.
Frequently Asked Questions
What is copper?
Copper is a metal element found in soil, rocks, air, and water. This is one of the essential minerals for the human body and can be found in many foods [1]. Additionally, copper is used in many industries, including the wiring, plumbing, cookware, dietary supplement, and pesticide industries [12]. This metal can also be combined with other metals to make brass and bronze pipes.
How do people get exposed to copper?
You can get exposed to copper in many ways. For example, you may ingest it from food and water, inhale it in the air, or touch products with copper.
Drinking water in your home may have high copper levels if you have acidic water or copper pipes. This type of copper overload will likely happen in a home or building that uses copper plumbing due to corrosion [2]. Additionally, one may ingest copper sulfate crystals.
What are the benefits of copper?
Copper is one of the essential minerals that people need to take in daily food. A healthy amount of copper in the bloodstream works alongside iron to form red blood cells and maintain the body’s immunity [3]. It is also important in iron absorption.
On the other hand, consuming large amounts of copper can lead to copper poisoning. The symptoms of copper poisoning include diarrhea and vomiting, abdominal pain, and in the long term, liver and kidney dysfunction and, eventually, death [3, 8].
Does boiling water help to remove copper?
Unfortunately, boiling water does not eliminate copper. On the contrary, when water evaporates, it can increase the concentration of copper in water and make the water even more dangerous when consumed.
Does copper affect pool water?
Yes, copper can affect pool water. First, it affects pool water by staining the pool. Additionally, copper can affect swimmers’ swimsuits, hair, and nails. For example, the green tinting on hair and swimsuits is normally blamed on chlorine in water but is often caused by copper [20]. Copper is introduced into the pool water to prevent the buildup of algae. However, to prevent staining, the levels of copper need to be kept below 1.0 ppm. One can check their pool water regularly to help monitor copper levels.
What is copper water, and what are its benefits?
Copper water has recently become a health trend. This trend has been inspired by Ayurveda, a holistic medicine system with its roots in India from over 3000 years back. It involves storing water in copper bottles, which is believed to improve health, aid digestion, and improve your general immune system.
While copper is good for your health, the amount in your diet should not be more than 0.9mg of copper daily. Therefore, there is no need for you to put your water in a copper bottle and infuse it with more copper.
How do you test for copper in water?
There are several methods for testing for water in copper. One can perform a test with a home test kit. However, it is often inaccurate and not advisable. It is recommended to contact a professional water testing company that utilizes state-certified partner NELAP laboratories to perform professional-certified testing.
If you have a private well, it is important to note that copper will not be in the groundwater that feeds it. Instead, the copper will likely get into the water through the plumbing system. Therefore, you need to test all or at least a representative sampling of points of use on the subject premises. This may include wash sinks, food prep sinks, bathtub and shower points of use.
Test for Copper in Your Drinking Water
While your water may taste normal if you take the steps above, you may still be concerned about copper levels. This step could especially be crucial if you have a child under one year or one of your family members has Wilson’s disease. In such cases, you will want professional analysis to ascertain if your drinking water has elevated levels of copper and the exact amount.
