Young Adults with Lived Foster Care Experience Who Later Experience Houselessness: an Exploratory Latent Class Analysis.

Young adults with lived experience in out-of-home care during childhood report later experiences of housing instability as common. Existing literature identifies a host of factors compounding an individual's risk of experiencing houselessness, but research has yet to explore constellations of characteristics which describe youth formerly in care who later become unhoused. This exploratory study leverages a public-private data linkage collaborative to integrate and de-identify child welfare data extracted from a Rocky Mountain state's administrative database and houselessness service utilization data from a regional provider in a large metro area of the state.

Spatial pattern of groundwater arsenic occurrence and association with bedrock geology in greater Augusta, Maine.

In New England, groundwater arsenic occurrence has been linked to bedrock geology on regional scales. To ascertain and quantify this linkage at intermediate (10(0)-10(1) km) scales, 790 groundwater samples from fractured bedrock aquifers in the greater Augusta, Maine area are analyzed, and 31% of the sampled wells have arsenic concentrations >10 microg/L. The probability of [As] exceeding 10 microg/L mapped by indicator kriging is highest in Silurian pelite-sandstone and pelite-limestone units (approximately 40%).
