3 EXECUTIVE SUMMARY: Subsequent to the discovery of a nearby contaminated site, the Bronxville School District engaged Omega Environmental Services to conduct a preliminary investigation related to potential Vapor Intrusion. The investigation consisted of real-time VOC screening, as well as representative soil and ground water sampling as describe below. Results of the sample analysis revealed: - All VOCs, hexavalent chromium, herbicides, and PCBs results were none detected. - A few pesticides are present in soil and groundwater above NYS limits. - Heavy metals and PAHs (Polynuclear Aromatic Compounds) were identified in soil and groundwater above NYS limits. It is Omega s understanding that the area is to be returned to an asphalt paved parking lot thus preventing direct contact exposure. PRESENT SITE ACTIVITES: Due to flooding issues a new storm water drain system is being installed in the Elementary School Parking lot. The project includes soil excavation and de-watering activities. This exposed soils and groundwater for sampling and VOC screening. Groundwater is reportedly present at a depth of only 5 feet below ground. TESTING METHODOLOGY: Prior to soil sampling the excavated work area was screened for airborne Volatile Organic Compounds (VOCs) using a calibrated PID (Photoionization Detector) capable of reading to a ppb (parts per billion) level. Two soil piles existed on the site on the day of inspection. One is located at the northwesterly end of the parking lot. This pile was reportedly from previously excavated soil earlier in the project. A second newer pile was present at the southeasterly corner of the parking lot (near Midland Ave.). Soil was being added to this pile on the day of inspection. A composite soil samples were collected from each soil pile from a depth of 6 to 2 into each pile ( and ). Also, the excavation was being extended to the northeast (along Midland Ave.) on the day of inspection. Once the excavation was close to the final planned depth (approximately 0 feet below ground surface (bgs)), a sample of freshly exposed soil was collected (307-06). Two dewatering wells exist along Midland Ave. Although not true groundwater samples for potable water assessment in accordance with NYS DEC requirements, the samples were intended Page 3 of 9: Elem. School Parking Lot GW/VI Investigation Report, {Omega Project#: 6-307} Omega Environmental Services, Inc. 280 Huyler Street - South Hackensack, NJ Tel: (20) Fax: (20)

4 to determine if significant contamination was present. One sample was collected from each well by directly filling glassware from the water discharge hoses (307-0 and ). A groundwater monitoring well exists in the Elementary School parking lot. Groundwater was encountered at a depth of approximately 5 feet bgs. The well was purged of 5 volumes of water and a sample collected. All samples were hand delivered to Accredited Analytical Laboratories in Carteret, NJ. All samples were analyzed for the following parameters: Volatile Organic Compounds (VOCs) plus a library search of unidentified VOC compounds (EPA method 8260). Semi-volatile Compounds/BNAs (SVOCs plus a library search of unidentified SVOC compounds (EPA method 8270). Heavy Metals Target Analyte List (TAL) of 22 metals. Hexavalent Chromium (Cr6). PCBs Pesticides Herbicides ANALYTICAL RESULTS: No airborne VOCs were detected above background levels. No odors, distressed vegetation, or discolored soils were detected.

Vapor Intrusion concerns are generally related to VOCs. Therefore, the results of this testing do not indicate that further Vapor Intrusion investigation is warranted at this time. The presence of a few pesticides is likely due to local usage. The presence of heavy metals and PAHs may be due to background levels or, more likely, poor quality historic fill. RECOMMENDATIONS: Once the work in the area is completed, it is Omega s understanding that it will be returned to an asphalt paved parking lot. The groundwater on site should not be used for any potable purposes. Use for irrigation purposes may be acceptable, but further evaluation would be required. Page 7 of 9: Elem.
