Summary Table: Risk Estimates for Cancer and Noncancer Adverse Health Effects

 

Contaminants	Highest Detected Indoor Air Level1 (mcg/m3)	Noncancer Health Comparison Value2 (mcg/m3)	Estimated Noncancer Risk	Cancer Health Comparison Value2 (mcg/m3)	Estimated Increased Cancer Risk
EDF	0.8	9	minimal	0.0017	moderate3
PDC	4	400	minimal	0.077	low
BCH	33	4004	minimal	---	---
MFBDC	71.6	70	low	---	---

1The highest detected indoor air levels exceed typical background indoor air levels and/or public health assessment comparison values

 2Comparison values are determined for a 70-kg individual who inhales 20 cubic meters of air per day.  The cancer comparison value is the air concentration corresponding to an increased lifetime cancer risk of one-in-one million.

3The cancer risk estimate assumes continuous (i.e. uninterrupted) exposure for 24 years, which probably overestimates the amount of time that people spend in their basements, particularly if basements are used as storage areas.  Consequently, using these exposure assumptions likely overestimates the cancer risk.  If it is assumed that 8 hours per day are spent in the basement, the estimated cancer risk for EDF is low.

4Based on PDC.

Remedial Actions	Location	Date	Function	Results
(engineering controls designed to reduce exposure)
Groundwater migration-control trench & 7 pumping wells (IRM-1)	Agre eastern (downgradient) property line	Jan 1996	Designed to trap and remove contaminants in the groundwater flowing off Agre property	Concentrations of contaminants in off-site monitoring wells was reduced by 95%
Bioventing system (IRM-2)	Railroad Spurs (overburden soil) south of Agre property	Dec 1997	Biodegrade petroleum hydrocarbon contaminants in the overburden soil & aquifer	Biodegradation is working but not enough to significantly reduce high concentration of contaminants
Sump pump and air-tight cover (Aluminum Bilco door and air-tight neoprene seal)	Residence  A basement (Washington St)	Apr 1998	Minimize potential for exposure to contaminants in sump water & vapor	Water is not physically accessible and airtight seal prevents vaporization
Air Filtration Devices	Residences A,B basements (Washington St)	Apr 1998	Remove vapors that might be enter the residence from soil-gas	Contaminants not detected in indoor air
