Ambient monitoring of volatile organic compounds at Los Alamos National Laboratory in technical area 54, areas G and L. Final report

PDF Version Also Available for Download.

Description

Ambient air monitoring for volatile organic compounds (VOCs) was conducted at TA-54 to characterize non-radioactive air emissions to determine if the Laboratory`s waste operations are releasing significant amounts of VOCs to the ambient environment. Samples were collected at four locations along the northern fenceline (dominant downwind side) of Areas G & L and at a background site located in Bandelier National Monument. Eight-hour integrated samples were collected in evacuated canisters during daylight hours on each of eight days during the summer of 1994, for a total of 40 samples. The samples were analyzed by gas chromatography following EPA Method TO-14 ... continued below

Description

Ambient air monitoring for volatile organic compounds (VOCs) was conducted at TA-54 to characterize non-radioactive air emissions to determine if the Laboratory`s waste operations are releasing significant amounts of VOCs to the ambient environment. Samples were collected at four locations along the northern fenceline (dominant downwind side) of Areas G & L and at a background site located in Bandelier National Monument. Eight-hour integrated samples were collected in evacuated canisters during daylight hours on each of eight days during the summer of 1994, for a total of 40 samples. The samples were analyzed by gas chromatography following EPA Method TO-14 for a target list of 68 analytes. In general, about two dozen volatile organic compounds (VOCs) were identified in each sample, including those collected at the background site, but the concentration levels were very low (e.g.; < 1 to 10 ppbv). The average total non-methane hydrocarbon (TNMHC) concentration ranged from 4.3 to 22.8 ppbv at the Area G and L sites as compared with an average of 4.2 ppbv at the background site. The measured concentrations were compared with action levels developed by the New Mexico Environment Department and were well below the action levels in all cases. Methanol and benzene were the only compounds that ever exceeded 1 % of the action level. The measured VOC concentrations were collected during the warmest months of the year and therefore should represent worst-case air impacts. Based on the results of this study, VOC emissions from Areas G and L have an insignificant impact on local air quality and pose no health risk to workers or nearby populations.
