Lulac Village Park Apartments
1417 Horne Road 		June 15, 2000 Apartments sampled: 1505B, 1513A, 1521B, and 1447A. Samples were taken in each bedroom closet, next to an outlet in each bedroom, under the bathroom sink, and in each cabinet adjacent to the kitchen sink. In apartment 1447A the bathtub had been removed exposing a hole in the slab; a sample was taken 3 feet below the slab. All samples non-detect (0% methane)

* CREG - Cancer Risk Evaluation Guide are based on EPA's chemical specific cancer slope factors and an estimated excess lifetime cancer risk of one-in-one million persons exposed for a lifetime.
** intEMEG and chrEMEGs - are intermediate and chronic Environmental Media Evaluation Guide based on ATSDR's minimal risk levels. Minimal Risk Levels are estimates of a daily exposure to a contaminant that is unlikely to cause adverse non-cancer health effects.
"†" The CREG value was converted from micrograms per cubic meter to parts per billion (ppbv) so that it could be readily compared to the site measurements.
