Public Health Assessment for Petitioned Public Health Assessment Marine ShaleProcessors, Inc., Amelia, St. Mary Parish, Louisiana, Region 6. CERCLIS No. LAD981057706

摘要

Marine Shale Processors, Inc. (MSP), Morgan City, LA, processes solid andhazardous wastes in a large industrial kiln to ultimately produce an aggregate. This public health assessment is an evaluation of existing environmental data, both on and off site, local health outcome data, and community health concerns. The contaminants of concern identified in this assessment include lead and cadmium associated with the aggregate. Available data show there is contamination both on and off site resulting from activities at MSP. However, close examination of the environmental and potential human exposure pathways indicated contamination is below levels of health concern. Using the findings described and identified data gaps, ATSDR considers the site an indeterminate public health hazard. The conclusion is based primarily on the data gaps about the safety of the aggregate under conditions of chronic exposure and its use in areas where dust generation and inhalation could occur.
