This report discusses the emerging development of nationwide alert systems to recover missing adults, such as those with mental impairment (such as Alzheimer's disease), developmental disabilities, or suicidal tendencies. This report provides an overview of such alert systems in 11 states: Colorado, Delaware, Florida, Georgia, Kentucky, North Carolina, Ohio, Oklahoma, Rhode Island, Texas, and Virginia. This report also provides a discussion of issues for Congress to consider with respect to the federal role, if any, in developing state alert programs for missing adults.

From abstract: This report presents preliminary results of stream sediment and ground water reconnaissance in the Greensboro National Topographic Map Series (NTMS) 1° x 2° quadrangle. Stream sediment samples were collected from small streams at 1240 sites for a nominal density of one site per 13 square kilometers (five square miles) in rural areas. Ground water samples were collected at 774 sites for a nominal density of one site per 25 square kilometers (ten square miles).

Supplementary data including stream characteristics and additional elemental analyses to accompany a report on hydrogeochemcial and stream sediment reconnaissance in North Carolina, Virginia, and Tennessee.
