Proposed Project: Assessment of Exposure to Arsenic through Household Water, OMB No. 0920-0472—Revision—National Center for Environmental Health (NCEH), Centers for Disease Control and Prevention (CDC).

Background

Arsenic is a naturally occurring element present in food and water as both organic and inorganic complexes. Epidemiologic evidence shows a strong link between ingestion of water containing inorganic arsenic and an increase in certain cancers (e.g., bladder cancer, lung cancer). Although consumption of arsenic-contaminated food is the major source of arsenic exposure for the majority of U.S. citizens, in some areas of the United States, elevated levels of arsenic occur frequently in water. In such areas, ingestion of water can be the primary source of arsenic exposure.

Currently, point-of-use (POU) devices are the preferred method of treatment of private domestic well water containing elevated levels of arsenic. Bottled water and POU treatment systems are considered effective means of managing arsenic exposure based on the assumption that people's other water exposures, such as bathing, brushing of teeth, cooking, and drinking occasionally from other taps, contribute relatively minor amounts to a person's total daily intake of arsenic.

We propose to conduct a study to methodically test the validity of the commonly made assumption that secondary water exposures, such as bathing, will not result in a significant increase in arsenic exposure above background dietary levels. Specifically, we are interested in assessing total urine arsenic levels and levels of organic and inorganic arsenic species among people in areas in which ingestion of arsenic-containing water is controlled by either POU treatment or use of bottled water.

Potential participants who are interested in being part of the study will be interviewed by telephone. Recruited participants will be asked to participate in a survey interview about potential exposures to arsenic. Participants in the study will use short-term diaries to record diet, water consumption, and bathing frequency. In addition, we will assess long-term arsenic exposure by analyzing toenail samples for total arsenic.

The total annualized burden hours are estimated to be 2,689. Start Printed Page 46645
