Copper Concentrations In Water

Copper concentrations in tap water and possible effects on,

In total, water samples from 1674 households with infants were tested for copper. The mean copper concentration was 0.18 mg/L in the 1619 collected stagnation samples and 0.11 mg/L in the 1660 random daytime samples. There were notable regional differences in copper values.
