26 Citations | Furthermore, our findings support the existing hypothesis that the available concentration of hydrogen ions, rather than DO, is the limiting factor for copper release into drinking water. |
| The results support the safety of the World Health Organization's provisional guideline value for copper in drinking water during infancy. | |
19 Citations | Theory and practical experiences suggest that higher copper levels in drinking water tap samples are typically associated with newer plumbing systems, and levels decrease with increasing plumbing age. |
| Copper in natural water samples can be determined easily. | |
22 Citations | Current policies and regulations pertaining to food fortification, nutritional supplements, and drinking water appear to be effective in providing for adequate copper intakes in many populations, although high levels of exposure, through overzealous fortification, supplementation, or drinking water exposure, may be possible under some circumstances. |

What is copper contamination in water?2 answersCopper contamination in water refers to the presence of excessive copper ions in water, which can have negative effects on both the environment and human health. Copper is a heavy metal that can pollute the environment and is difficult to eliminate. Drinking water can become contaminated with copper through various sources, such as copper pipes used in household plumbing. Exposure to copper-contaminated water can lead to gastrointestinal issues, hepatic problems, renal damage, and even exogenous pigmentation, such as green hair. The ability of water to retain copper depends on the nature of the complexes formed with organic materials, such as humic and fulvic acids, as well as anthropogenic substances like ethylenediaminetetraacetic acid (EDTA). These complexes can determine the toxicity of copper to aquatic biota and its transport in the environment. Overall, copper contamination in water is a significant concern due to its potential health and environmental impacts.
What places experience copper contamination in water exceeding standards?5 answersCopper contamination in water exceeding standards has been observed in various locations. In Alaska, un-reclaimed drill-holes and drill waste disposal practices have resulted in elevated copper concentrations in surface water and sediment at certain sites. In homes in New South Wales, Australia, detectable concentrations of copper in drinking water samples exceeded the Australian Drinking Water Guidelines in 5% of cases. At the Erdenet Mine in Mongolia, water samples from tailing water, the Khangal River, and groundwater showed high concentrations of copper. These findings highlight the need for improved regulatory oversight and measures to mitigate the environmental impact of copper contamination in these areas.
Which places in europe experience copper contamination in water exceeding standards?5 answersCopper contamination in water exceeding standards has been observed in the Rosia Poieni ore deposit in the Apuseni Mountains in western Romania. The mine waters in this area are acidic and transport large amounts of toxic elements, including copper, into the environment. Additionally, private houses in the Sibylline Mountains National Park in central Italy have been found to have substantially higher copper concentrations in their water, possibly due to release of metals from old metal pipes. These areas are experiencing copper contamination in water that exceeds the standards set by Italian and European legislation for drinking and natural mineral water.
