Proving Coppers Benefits On Drinking Water
With Laboratory Testing

Water Testing Pure Copper Water Bottles For:

  • BACTERIA: Confirm copper’s effectiveness to kill bacteria and record the kill rate
  • COPPER CONTENT: Monitor the transfer rate of copper ions to drinking water
  • SAFETY: Check the level of copper ions do not exceed health guidelines
  • ALKALIZING: Record the alkalizing effect of copper on water
Test water from copper bottle

Water Eggs design, produce and supply copper water dispensers and water bottle products with your health in mind.

It is important that we can say with absolute confidence, the testing and research has been done to qualify copper as one of the best materials to use, if not the best, for water storage with health benefits.

Copper’s dynamic properties have been scientifically researched and verified by peer-reviewed studies.

Copper Kills Bacteria – Lab Verified

The water laboratory collected a river water sample known to be polluted with human waste and infected with E. Coli bacteria. The water testing lab found the water sample had an E. coli bacterial count of 5360 colony forming units (CFUs) per 100 ml of water!

The river water sample was placed in a Water Egg pure copper water bottle and 4 samples were taken from the copper bottle over the next 24 hours to monitor the number of bacteria in the water.

After only 4 hours the bacterial count was reduced by 78%.

There are many articles that discuss copper as being a highly effective antibacterial and being used in hospitals to reduce the incidence of hospital-acquired infections. Read more about copper’s antibacterial properties

Testing For Copper Content
The purpose of the next three (3) tests was to know how much copper is transferred from the copper bottle to the water inside, is the water safe to drink, and does the copper bottle transfer a nutritional value to your drinking water?

Why Copper Is Important
A marginal copper imbalance has been linked to impaired immune function, bone demineralization, and increased risk of cardiovascular and neurodegenerative diseases.

Copper Intake Guidelines
*The tolerable upper limit for copper is 10 mg per day (WHO)
*The recommended daily allowance (RDA) of copper for an adult is .9 mg per day (U.S. Department of Health and Human Services)

Test #1 – Check Copper Content Every 24 Hours

The Question: Is it safe to drink water from the copper bottle every day?

One water sample was collected from the copper water bottle every 24 hours for five days. The bottle was emptied and refilled with fresh water after each sample reading. The first reading showed the highest reading, which was 27% of the recommended daily allowance (RDA).

Note: The test bottle in this test was not a new bottle and was previously used to store water. It had not been used for thirty days and therefore some copper oxides were present on the inside surface of the bottle. This explains why the first reading was a higher reading than following four readings.

Test #2 – Measure Copper Content After 7 Days

The Question: Does copper accumulate in the water over time?

A pure copper Water Egg bottle was filled with pH adjusted deionised water (pH7 – neutral) and left to stand for 7 days. Without changing the water, 5 water samples were taken from the bottle to measure the copper content in the water sample.

The water lab tests found the copper content was stable and copper ions did not continue to accumulate in the water sample.

Result: The water inside the copper bottle was safe to drink and did not exceed the RDA.

Test #3 – Measure Copper Content During Continuous Use

The Question: If 2 litres/66 fl oz of water from the copper bottle is consumed in a 24 hour period, how much copper am I drinking?

Testing was done twice daily for 4 days. The first test sample was taken after 8 hours, and the second test sample was taken after 16 hours. After each sample reading the bottle was emptied and refilled with fresh water.

The amount of copper that could be ingested in a 24 hour period was on average 25% of RDA

Alkalizing Water With Copper

The Question: How fast does copper alkalize water?

Claims are made about copper’s ability to alkalize water.

The water laboratory tested two water samples over 10 days.

Findings: The alkalizing effect of copper was greater in the sample (A) pH of 4.2 than the sample (B) pH 7 – neutral. The most significant increase in alkalinity in both water samples (A) and (B) was in the first 24 hours. Overall, the alkalizing effect decreased the longer the water samples were in the copper bottles.
