High doses of copper, for example a dose of 15 mg can cause nausea, vomiting, diarrhea, and intestinal cramps. In drinking water, the primary source of lead is from pipes, which can present a risk to the health of children and adults. However, some states, such as Nebraska and Delaware, have difficulty maintaining copper levels below this goal. Copper . Therefore, a public water system must take action to reduce the amount of lead in the water if more than 10 percent of the water samples have lead levels over 15 ppb. A maximum acceptable concentration (MAC) of 0.005 mg/L (5 g/L) is proposed for total lead in drinking water, based on a sample of water taken at the tap and using the appropriate protocol for the type of building being sampled. Lead in drinking water fails to leave a . It serves no health benefit in humans and can only cause damage. perfectly safe to consume at low levels.

Microbiologically contaminated drinking water can transmit diseases such as diarrhoea, cholera, dysentery, typhoid and polio and is estimated to . Drinking water with more than 1,300 micrograms of copper per liter of water (g/L)* can be a health risk for everyone. The Action Level for copper in water has also been set at 1.3 ppm because EPA believes, given present technology and resources, this is the lowest level to which water systems can reasonably be required to control this contaminant should it occur in drinking water at their customers home taps. Recommendations officially state the limit for nitrates at 10 mg/L. Lead and copper are common metals found in the environment. Because no safe blood level has been identified for young children, all sources of lead exposure for children should be controlled or eliminated.

Lead and copper in drinking water present a potential health risk to building users. Safe and sufficient water facilitates the practice of hygiene, which is a key measure to prevent not only diarrhoeal diseases, but acute respiratory infections and numerous neglected tropical diseases. One more fact to be noted by the scientists from this study was that copper pot is as active in regular drinking-water (pH 7.830.4) as that in distilled water (pH 6.70.05), and the level of copper released in the regular drinking water is far less (17716 ppb) than that in distilled water (~420 ppb). Copper was also commonly used in plumbing systems and is susceptible to corrosion. The World Health Organization (WHO) recommends no more than 0.47 mg of copper per cup (2 mg per liter) of water. For treated drinking water, 2% of the samples were below the detection limit, and for those samples above the detection limit (n=1026), the median copper level was 0.009 mg/L with a maximum of 0.8 mg/L. Typical sources of copper from food range from less than 2 milligrams (mg.) to 5 mg. per day. Immediate effects from drinking water extremely elevated levels of copper . Lead is restricted in municipal drinking water by the SDWA to 15 ppb. According to the Environmental Protection Agency (EPA), it is safe to maintain copper levels in water at 1.3 parts per million (or 1.3 mg/L) or less. The EPA's stance is that there is no "safe" level of lead in drinking water for human health. What is the best pH water to drink?

In Western Australia all mains water supplies are continually monitored by the Department of Health to ensure copper levels do not exceed Australian Drinking Water Guidelines.These guidelines set two levels for copper: 1mg/L for aesthetics to prevent taste and staining problems 2mg/L to prevent any health related problems They considered communities in which 10% of the water samples, measured during a statewide survey in 1995, had copper concentrations greater than 5 mg/L. Lead is strictly banned because it can be toxic even in low doses, especially for infants and young children. At these levels, harmful health effects are unlikely to occur. Drinking water that is lower in pH can leach metals from pipes and fixtures, such as copper, lead, and zinc. The best pH for drinking water sits at a 7 right in the middle. The drinking water standard for copper is 1.3 mg/L (milligrams per liter), a level that is enough for the body to make red blood cells, but will prevent health effects.

However, EPA's current "action level" of fifteen parts per billion in drinking water. Any volume over this level is considered unsafe and must be dealt with accordingly. When excess copper is present, water has a metallic flavor (at 3 mg/l) and can leave a blue to green discoloration to surfaces. Children are especially susceptible to lead and copper exposure because their bodies absorb these elements at higher rates than the average adult. This corrosion occurs when the water has low pH or is acidic, and/or when the water has a low mineral content. What are safe levels of copper in drinking water? LCR also establishes a nonenforceable maximum contaminant level goal (MCLG) of 0, the level of lead in drinking water at which no adverse health effects are likely to occur. The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be pegged at 1.3 mg/L. The Australian Drinking Water Guidelines recommend that the level of copper in drinking water should be less than 2 mg/L (milligram per litre) to prevent any health-related problems and less than 1 mg/L to prevent taste and staining problems.
