A laboratory study was conducted to test the leachability of regulated metals from cement-mortar linings inside drinking water pipes. Faucet water of known quality was introduced in the test pipes and maintained in static, pressurized conditions for extended periods of time. Water samples were frequently drawn from the pipes and tested for metals and other water quality parameters during the test periods. Significant amounts of barium, cadmium, and chromium leached out from the cement-mortar linings in two of the three test pipes during the first 14 days of water stagnation. Barium and chromium continued to leach out at detectable levels as the pipes were subsequently refilled. The authors recommend that the water industry be selective in choosing cement for lining pipes.
