Queens Community Air Screen Results - Locust Grove Civic Association

Air samples were collected at the same location on two consecutive days in South Ozone Park in the borough of Queens. The samples were collected for 1-hour with a 6-liter sampling canister and analyzed using a laboratory method which evaluates the presence of 43 toxic air pollutants. During sampling on October 12, the winds were from the east, northeast and from the east, southeast during sampling on October 13.

Twenty-two toxic air pollutants were detected and all were well below the short-term health-based air concentration values. Therefore, the results would not be considered a potential public health threat or an immediate public health concern. The results also are below or within an order of magnitude of the long-term health-based air concentration values and similar to concentrations found in the DEC's ambient air monitoring network. Based on these comparisons, DEC staff concluded that follow-up sampling will not be considered at this time.

Samples were collected in a residential neighborhood approximately 5000 feet from the primary source of concern, Jamaica Wastewater Treatment Plant. The contaminants released from the plant that would be reported by the sampling method in this Program are toxics such as chloroform, bromodichloromethane and dichloromethane. The concentrations found in the two samples collected were low for chloroform and dichloromethane, and bromodichloromethane was not detected. Common odorous gases released from wastewater treatment plants include hydrogen sulfide and ammonia. These gases are not captured by the sampling method used in this program.

In conclusion, this short-term screening assessment did not identify concentrations of toxic air pollutants that would be considered a public health concern. Additionally, the results do not indicate the need for follow-up sampling at this time.
