Elevated copper levels in drinking water may significantly increase your exposure to copper and cause adverse health effects. You may find that there is a metallic taste in your drinking water before copper levels are high enough to cause adverse health effects. You may also notice blue or blue-green stains around sinks and plumbing fixtures. The only way to be certain of the copper level in your drinking water supply is to have the water tested. It is recommended that you use a laboratory that is state certified to analyze copper levels in drinking water.
If you are being served by a public water system, the owner of the utility will have results of copper sampling which has been done in parts of the distribution system. If the EPA action level of 1300 ug/l for copper is exceeded in more than 10% of samples collected, the utility must conduct further testing to determine if the corrosivity of the water is contributing to an increase in the copper levels. They are also required to optimize corrosion control measures to reduce the corrosivity of the water to acceptable levels. If you have any questions regarding copper monitoring, contact your water utility.
If you are experiencing elevated copper levels in drinking water, it may be likely that lead levels are also elevated. This is especially true if the plumbing system in your home or apartment contains lead solder joints, lead service lines, or brass fixtures. Since lead and copper enter drinking water under similar conditions, it is advisable to test for lead when testing for copper.
