Technical Note: Increased Distance Between Galvanic Lead: Copper Pipe Connections Decreases Lead Release

It has recently been proposed that lead contamination of drinking water arising from galvanic corrosion of lead and copper pipe will be minimized if the lead and copper pipes are brought into direct contact when compared to pipe separations of 1 cm to 15 cm and external electrical contact via a grounding strap. A direct, four month test of this hypothesis was conducted with measurement of galvanic current and lead release to water.

Public Reporting of Healthcare-Associated Infections: Epidemiologists’ Perspectives

Public reporting of healthcare-associated infections is pervasive, with 33 states and the District of Columbia mandating public disclosure. The authors surveyed hospital epidemiologists on the perceived value of state public reports. Respondents believed consumers are unaware and do not consider the information important, but they indicated that epidemiologists have a role in consumer education.

Discussion: Effect of Changing Water Quality on Galvanic Coupling

Two galvanic pipe-loop couples (lead-copper and lead-bronze) were exposed to controlled changes in water quality (disinfectant, pH, alkalinity, and phosphate) and monitored for changes in lead and copper release. In addition, open circuit potential profiles were measured along the junction of dissimilar metals to determine the extent of the zone affected by galvanic coupling.

Do Specialty Courts Achieve Better Outcomes for Children in Foster Care Than General Courts?

This study finds that children in counties with unified family courts experienced shorter foster care spells and higher rates of reunification with parents or primary caregivers. Shorter foster care spells translated into improved school performance measured by end-of-grade reading and math test scores. Adult drug treatment courts were associated with lower probability of reunification with parents/primary caregivers.
