Follow-Up Review of Air Sampling Data
Follow-Up Review of Air Monitoring Data
September 29 - October 2
The Department of Health and Senior Services (DHSS) has reviewed air quality monitoring data collected by the Department of Natural Resources (DNR) at Bridgeton Landfill from the afternoon of September 29 to the afternoon of October 2, 2014.
DNR provides continuous monitoring of reduced sulfur compounds (reported as hydrogen sulfide), sulfur dioxide, carbon monoxide, and total volatile organic compounds (VOCs) at three fixed locations as well as routine, twice daily, surveillance of hydrogen sulfide, benzene, and odor levels around the entire periphery of the landfill. 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 occasional light, moderate, and strong odors at various locations during this time period. DHSS continues to recommend that during periods of objectionable odor, sensitive individuals should stay indoors as much as possible, avoid outdoor exercise, and seek medical advice for any acute symptoms. Symptoms associated with exposure to strong odors include headache, nausea, and fatigue. Symptoms generally associated with strong odors typically disappear once the odors dissipate.
Hydrogen Sulfide and Other Reduced Sulfur Compounds
Hydrogen sulfide concentrations were below levels of public health concern. Hydrogen sulfide levels are measured by the highly sensitive Jerome meter, which detects hydrogen sulfide specifically. Reduced sulfur compounds were periodically detected by AreaRAE monitors, but previous sampling has shown that these detections are primarily due to a reduced sulfur compound with strong odor but lower toxicity.
Sulfur Dioxide
Sulfur dioxide concentration readings were recorded above levels of public health concern for several hours on October 1 and 2 in a residential location southeast of the landfill. During this time the monitors were experiencing fluctuations, potentially due to weather conditions including high humidity and changes in pressure from a passing storm. While sulfur dioxide readings were fluctuating, winds were predominantly from the south, rather than from the direction of the landfill. Exposure to the elevated levels of sulfur dioxide may cause respiratory irritation or other short-term symptoms, particularly in asthmatics or other sensitive individuals.
Benzene and Total VOCs
Benzene was not detected in ambient air at any of the surveillance locations around the landfill during this time period. There are no health-based screening values for total VOCs. However, total VOC data are used to identify the need for compound-specific sampling. To be proactive, DNR is performing weekly VOC compound-specific sampling in locations upwind and downwind of the landfill. The laboratory results are submitted for DHSS review of public health concerns and that analysis is regularly posted online.
Carbon Monoxide
Average carbon monoxide concentrations were below levels of public health concern.
Radiation Rates
Gamma radiation rates continue to be indistinguishable from natural background levels and were below levels of public health concern.

Reduced sulfur compounds were periodically detected by AreaRAE monitors, but previous sampling has shown that these detections are primarily due to a reduced sulfur compound with strong odor but lower toxicity. For less than two hours during this time period, the readings from one AreaRAE unit were determined by DNR to be inaccurate due to weather conditions including high humidity. As such, these data were considered erroneous and not evaluated. DNR staff used handheld instruments to confirm that actual levels were not elevated.
Sulfur Dioxide
Sulfur dioxide concentrations were below levels of public health concern during this time period, except for one hour at a commercial location southwest of the landfill. Exposure to the elevated levels of sulfur dioxide shown on that one monitor may cause respiratory irritation or other short-term symptoms, particularly in asthmatics or other sensitive individuals.
