The survey covers different types of waters, including treated and untreated well and surface supplies, and softened water (private and municipal). In each case the copper values are correlated with the age of the plumbing and the analysis of the water. The copper was determined by the modified diethyldithio-carbamate method. Although amounts of copper such as were found are toxic to many kinds of fish, they are not harmful for human consumption.
