How To Test For Copper In Water? Step By Step Guide

How-To-Test-For-Copper-In-WaterWater is a luxury and should always be treated like such and for that purpose, it should always be consumed when it is pure and contaminant-free. Sometimes though, water may incorporate other impurities, minerals, and metals which disturbs its pH and composition in order for it to be used in a healthy manner.

Most often, it could be related to the use of copper in the pipeline system of your household water supply, the mineral content or presence of metals in water, faulty pipelines that have deteriorated, etc. A fun fact is that copper is a chemical that is naturally produced within the soil so it is quite simple that it can be mixed with your supply of water, especially in the case of well water or the use of private water reservoirs.

This article will provide an easy step-by-step guide to testing for copper in water and help you figure out how you can do it effectively.Here are some of the things you need to know if you want to know if UV-treated water is safe to drink or not:

Private Testing


The first thing you can do is to test for copper in water by yourself by using home test kits that are easily available everywhere. The type of test depends upon your preference, amount, or presence of copper in water or the capacity of the water that needs to be tested.

The best part about these private test kits is that they are inexpensive and readily available so you can even carry them everywhere. Some of them target the water just for copper testing while others may include testing for other kinds of impurities.

Steps For Testing:

  • The first step is to collect the water that you need to test for the presence of copper, the water should be about 30 ml. 
  • Dip the testing strip into the water and let it sit there for 30 seconds to a minute and you should be able to see the colour change on the testing strip.
  • Again, wait for 2 minutes then compare the colour on the testing strip with the given chart (included in the kit)
  • This will help you identify the level of copper in water so you can take the next step.

Specialist Testing


A better way to check and test your water for copper is to get it tested by a certified institution that will offer you a better view of what actually is going on with your water supply. Most labs have a similar way to test the water so there is not a big difference in terms of whichever lab you select. The biggest benefit of a lab test is that not only do they detect the presence of copper but also give detailed results on what kind of treatment you should go for.

Steps For A Lab Test:

  • The first step is to contact a lab of your choice and they will send you a testing kit in your mail.
  • The kit usually comes with vials, so your job is to collect the water in question which you feel has copper in it, then send it by mail to the laboratory.
  • Because the lab tests are more thorough and comprehensive than home test kits, it will take around a week to get the results and after that, you will be given your results in your email.

If The Test Is Positive

After you have conducted your tests in your own selected and preferred method, the next step is to determine what to do. First of all, figure out the reason behind the presence of copper in your water; is it your copper pipelines that supply water into your house, or is it because the deteriorated pipes have allowed the copper to seep into the water from the soil.

A lot of water filter systems such as the Ro water system, ion exchange or water softening system as well as the filtration systems with carbon technology. The reverse osmosis system is more thorough, and it removes most TDS including copper.

Also, make sure to test your water at least once a month so that you can determine the levels of copper based on its cause.

Additional information

You must wonder how and why copper gets in your water, so here are the answers. First, it is a chemical that is produced in natural conditions such as in the soil, and rocks specifically in a water aquifer system if you are using groundwater.

In addition, human actions such as farming and industrial activities also result in the transfer of copper into the soil in the form of waste material. Lastly, the most common reason is the corrosion of your plumbing system which desperately calls for attention.

So how can you identify if your water has copper? Because that is the first sign that you will see and take action on. If you keep noticing bluish and green markings around your bathroom, pipes, faucets, or in your water after you use it, then this shade reflects low levels of copper.

If you are drinking the water and taste bitterness like a metal presence, then it is obvious that your water has copper elements in it. The environmental protection agency does keep a check on the presence of water in copper on a daily basis but in case you are using a private well, chances are your water may have a higher copper content.


Is copper in drinking water dangerous for health?

Yes, it acts like a slow poison and accumulates gradually in your liver, lungs, and blood. This weakens your entire immune system.

Does copper cause rust?

Yes, you can notice green stains on your faucets and metal fixtures all around the house and it also leaves a stain on your laundry.

Final Thoughts

In conclusion, if you have to test for copper in water, the steps and ways are quite simple, and the way that you select depends on your personal preference. The above-mentioned methods are simple and authenticated to successfully test for copper in your water supply.
