PUBLIC HEALTH ASSESSMENT

UNION PACIFIC RAILROAD YARD
SACRAMENTO, SACRAMENTO COUNTY, CALIFORNIA


CONCLUSIONS

Based upon the information reviewed, CDHS does not consider the Union Pacific Railroad Yardto pose a current health hazard. The Union Pacific site may have posed a health hazard (skinchanges) to the people who lived at 2206 6th Avenue before the contaminated soil in thebackyard was removed in 1991, but not to other neighbors This is based on a toxicologicalevaluation that found, if a child played exclusively in the area of the backyard where the arseniclevels were highest, the child might have experienced noncancer health effects, such as skinchanges. However, if the child played on average throughout the backyard, the arsenic in the soilwould not have posed a health hazard. The soil in the backyard of 2206 6th Avenue would nothave posed a noncancer health hazard to adults living there. If any residents lived at this housefor seventy years, they would have an additional low increased risk of developing cancer basedon a life-time exposure to the arsenic in the backyard. This soil has been removed so there is nocurrent public health hazard for the residents of 2206 6th Avenue.
