During an investigation in Delaware of health effects associated with elevated copper levels in drinking water, the NCEH found that gastrointestinal symptoms consistent with copper toxicity were not higher in people living in households with high copper levels than in those in control households (CDC, 1998~. The NCEH is conducting ongoing studies to assess the impact that prenatal exposure to disinfection byproducts (DBPs)

Surveillance is a critical component in the effort to reduce the impact of waterborne illness on public health; it is necessary to document the occurrence of illness, to investigate potential Biological agents, to plan and evaluate the effects of interventions, and to ensure appropriate care for people in need of services. Public health officials need surveillance methods that allow them to rapidly detect WBDOs and to initiate preventive measures (e.g., advisories to boil water)

As a complement to public health actions where areas of high exposure are identified, investigators could conduct epidemiological studies to document the health effects of exposure to the COC, and laboratories should develop biomarkers of human exposure to link levels of human exposure to health effects. These activities, both of which are currently being carried out by the NCEH for a wide array of chemical exposures, complement the information gained from experimental research on the effects of exposure of animals to chemical toxicants.

The NCEH is addressing the feasibility of conducting a study to assess MTBE exposure and health effects from contaminated groundwater in two eastern states. The planned study will be a case control epidemiological survey of water use and health effects, and the EVES will measure blood levels of MTBE to evaluate exposure, and DNA abducts and red blood cell apoptosis to evaluate health effects.

We at the CDC will continue to work with state and federal colleagues to address public health issues related to drinking water and to provide human health data to regulatory agencies for consideration during decisionmaking processes.
