Bridgeton Landfill Air Monitoring

September 2013 Updates

Follow-Up Review of Air Monitoring Data

Follow-Up Review of Air Sampling Data

 

September 26 - 30

The Department of Health and Senior Services (DHSS) has reviewed air quality screening data collected by the Department of Natural Resources (DNR) at Bridgeton Landfill from the afternoon of September 26 to the afternoon of September 30, 2013. On June 7, DHSS began issuing follow-up reviews of the daily air quality screening data on a twice-weekly basis.

On April 23, DNR began routine, twice daily, surveillance of hydrogen sulfide, benzene, and odor levels around the entire periphery of the landfill. In addition, DNR has provided continuous monitoring of reduced sulfur compounds (reported as hydrogen sulfide), sulfur dioxide, carbon monoxide, and total volatile organic compounds (VOCs) at three fixed locations. DHSS has reviewed both sets of data to identify potential public health concerns for short-term health effects. Generally, samples are collected near the property boundary and dispersion is expected to reduce exposure downwind of the sample locations.

Odors

DNR reported light odors during this time period at locations north, northeast, south, and west of the landfill.

Hydrogen Sulfide and Other Reduced Sulfur Compounds

Average hydrogen sulfide concentrations were well below levels of public health concern.

Sulfur Dioxide

Average sulfur dioxide concentrations were below levels of public health concern, except for several hours at one monitoring location.

Benzene and Total VOCs

Benzene was not detected in ambient air at any of the surveillance locations around the landfill during this time period.

Carbon Monoxide

Average carbon monoxide concentrations were well below levels of public health concern.

Radiation Rates

Gamma radiation rates were well below levels of public health concern.

The Department of Health and Senior Services (DHSS) has reviewed air sample data collected for the Department of Natural Resources (DNR) near Bridgeton Landfill on September 25, 2013. Samples were collected at two locations upwind of the landfill and two locations downwind of the landfill for laboratory determination of concentrations of volatile organic compounds (VOCs). DHSS has reviewed this data for evaluation of potential public health concerns of short-term health effects.

VOCs

Concentrations of VOCs were well below levels of public health concern. Downwind of the landfill, 10 VOCs were detected in ambient air in concentrations that generally exceeded concentrations detected upwind of the landfill. VOC concentrations ranged from 0.25 parts per billion (ppb) to 11.0 ppb and did not exceed health-based screening levels for acute exposure.
