Identifying Real Copper: Look at Your Item To distinguish copper from brass, which is an alloy of other metals, examine the color under good white light. Real copper should have a reddish-brown hue, like a penny. Brass items tend to have a yellowish tint.

Dip the strip in the sample three times and remove without shanking off excess water. Hold the test strip level for 2 seconds. Place the strip on the results color chart to determine the copper level of your water.

1.3 mg per liter
EPA has set a goal for copper at a maximum allowable level of 1.3 mg per liter of drinking water, to protect against short-term gastrointestinal tract problems. However, some states, such as Nebraska and Delaware, have difficulty maintaining copper levels below this goal.

Typically, a total blood copper test is ordered along with a ceruloplasmin level. If the results from these tests are abnormal or unclear, then they may be followed by a 24-hour urine copper test to measure copper elimination and/or a copper test performed on a liver biopsy to evaluate copper storage in the liver.

Most copper contamination in drinking water occurs through the plumbing system, as a result of corrosion of the copper pipes or fittings. The physical and chemical characteristics of water vary, including its corrosive properties. Private well owners should be concerned with the pH of their groundwater supply.

Copper can be removed from drinking water by one of several different methods, including reverse osmosis, distillation, and ion exchange filtering. Reverse osmosis works by forcing water through a membrane that allows water to pass through but blocks ions such as copper.

Eating or drinking too much copper can cause vomiting, diarrhea, stomach cramps, nausea, liver damage, and kidney disease. People with Wilson’s disease and some infants (babies under one year old) are extra sensitive to copper. Their bodies are not able to get rid of extra copper easily.

What is a ceruloplasmin test? This test measures the amount of ceruloplasmin in your blood. Ceruloplasmin is a protein that is made in the liver. It stores and carries copper from the liver into the bloodstream and to the parts of your body that need it.

Running cold water from the tap for about one minute can reduce copper that accumulates when household plumbing is not in use. Use cold water for drinking and cooking. Because hot water dissolves more copper than cold water, limit consumption of water from the hot water tap.

The Color Test Copper and brass are easily confused as they look so similar, but it’s their color that distinguishes them. Copper has distinct red and pink tones. Brass, on the other hand, appears more yellow and tends to be much brighter.

All you have to do is clean your copper item with a mixture of table salt and vinegar and then observe the color change to find out if your object is made of copper. If the color that comes out after cleaning shinning reddish-brown, then it is indeed copper in a considerably pure form.

Drinking water with more than 1,300 micrograms of copper per liter of water (µg/L)* can be a health risk for everyone. Infants and people with Wilson’s disease may need water with an even lower level of copper to stay safe. Copper can get into your drinking water as it passes through your plumbing system.

Copper mugs are quite safe to drink out of especially when you avoid hot beverages. The safest mugs have lining on the inside which prevents copper from getting into your drink. Here are some of the safest copper mugs. They have stainless steel interior lining.

Having copper in your water can cause damage even if you do not drink it. This contaminant can build up on your fixtures and leave behind unsightly stains. When copper corrodes, it becomes a green-blue color rather than the red-orange color that is easily recognized as copper.

Copper pipes are safe unless the water in it is overly acidic or alkaline. Most municipal water has a balanced pH between 6.5 and 8, which is a safe range for copper pipes. Acidic or alkaline water may cause corrosion or leech copper from the pipes into the drinking water.
