ATSDR’s Evaluation

Focused on dry-land soils Future site development

Residential Commercial/industrial

Divided property into ½ acre grids Current distribution of contamination in soil Some off-site soils Other pathways

Fish and shellfish Marsh Groundwater

10

Mercury Contaminant Map

Mercury Contaminant Map with ½ Acre Grids

11

Health Evaluation

Used average concentration per grid Estimated exposure doses for children,

adults, and workers Compared these doses to health guidelines Compared these doses to human and animal

studies Described possible harmful health effects Identified ½ grids that are a health concern

For residential use For commercial or industrial use

12

Dark and medium blue grids concern for PCBs in soil

13

Dark blue grids concern for mercury in soil

14

Dark and medium blue grids concern for lead in soil

15

Dark blue grids concern for PAHs in soil

Certain dry-land areas have chemicals in soils-- PCBs -- Mercury-- Lead -- PAHs

About 30 acres health concern for residential use 65 half-acre grids

About 5 acres health concern for commercial or industrial use 9 half-acre grids

20

Conclusions

Some uncertainty exists in these conclusions.

PCB and mercury contamination remains in the marsh area near the site

Clinker waste found on Clairmont Lane

Recommendations

Do not develop the LCP Chemicals Site for residential, commercial, or industrial use unless steps are taken to prevent contact with PCBs,

mercury, lead, and PAHs in soils.

22

Recommendations

Collect sediment and fish samples from the Altamaha Canal the on-site pond

Continue to monitor fish and shellfish from the Turtle River and the marsh near the LCP Chemicals Site

Investigate the clinker waste found in a back yard on Clairmont Lane
