How Did That Get in There?
Copper can enter the water through contact with the plumbing. Then it leaches into the water by dissolving or wearing away of metal caused by a chemical reaction between water and your plumbing. Copper leaches into water mostly from pipes, but fixtures, brass faucets, and fittings can also be a source. The amount of copper in your water depends on all the different minerals already in the water, how long the water remains in the pipes, the amount of wear inside the pipes, and the water’s acidity and temperature.
