All groups had equal chances of being affected by the All groups had equal chances of being affected by the contaminantscontaminants
Ground water was the source of drinking water supplyGround water was the source of drinking water supply
No threat from surface waterNo threat from surface water
No threat from indoor air to the residentsNo threat from indoor air to the residents
Contaminated water was used in all industrial processesContaminated water was used in all industrial processes
Soil and sediment posed equal risk and are not cumulativeSoil and sediment posed equal risk and are not cumulative

Conclusions Conclusions • Ingestion from soil and Ingestion from soil and sediment possess the highest sediment possess the highest exposure pathwaysexposure pathways
The soil and The soil and sediment are sediment are highly contaminated and are the highly contaminated and are the primary residue of most of the primary residue of most of the waste dumped by the companywaste dumped by the company
Dibenz(a,h)anthracene posed Dibenz(a,h)anthracene posed the largest cancer risk to the largest cancer risk to residents while Chyrsene was residents while Chyrsene was culprit for the non-cancer. culprit for the non-cancer.
Industrial workers Industrial workers were mostly exposed to arsenic, were mostly exposed to arsenic, and arsenic contamination posed and arsenic contamination posed the greatest hazard to arsenic.the greatest hazard to arsenic.
Most of the contaminants were Most of the contaminants were carcinogen thus making the carcinogen thus making the carcinogenic risk carcinogenic risk high while the non-cancer risk high while the non-cancer risk was non existentwas non existent
