1 55 Route 8 East, Suite 55 Cherry Hill, New Jersey T: F: July 9, 201 Mr. Michael T. Axelsson & Ms. Krystin Porcella 1 Meadow Spring Drive Bel Air, Maryland Subject: Point of Entry Treatment System Sampling Results May 14, 201 Sampling Event 1 Meadow Spring Drive, Bel Air, Maryland Dear Mr. Axelsson and Ms. Porcella: Brown and Caldwell (BC), on behalf of Drake Petroleum Company Inc. (Drake) would like to thank you for allowing us to conduct sampling of your point of entry treatment (POET) system on May 14, 201. The sampling was conducted to evaluate the effectiveness of the POET system that was installed to treat the water coming into your home. To help better understand the results, the following information is supplied: Pre-carbon filtration water sample of the untreated water coming directly into your home from your well; referred to as influent and denoted as 1 MEADOW-INF on the laboratory report. Mid-carbon filtration water sample collected between the granular activated carbon (GAC) vessels, this sample is collected between the second and third GAC vessels; referred to as mid-fluent and denoted as 1 MEADOW-MID2 on the laboratory report. Post-carbon filtration water sample of the finished treated water; referred to as effluent and denoted as 1 MEADOW-EFF on the laboratory report. Water samples were collected pre-, mid- and post-carbon filtration and were analyzed for volatile organic compounds (VOCs) including petroleum constituents, using a United States (US) Environmental Protection Agency (EPA) approved method for drinking water samples (US EPA Method 524.2). The following constituents were detected from the effluent post-carbon filtration sample: Chloromethane at 0.57 micrograms per liter (µg/l) and carbon disulfide at an estimated 0.11 µg/l. Chloromethane is not a petroleum-containing compound, and was below the Maryland Department of the Environment (MDE) groundwater standard of 19 µg/l for chloromethane. Carbon disulfide is used in a number of industrial applications and was below the MDE groundwater standard of 100 µg/l. The MDE groundwater standards can be found in MDE Cleanup Standards for Soil and Groundwater, Interim Final Guidance (June 2008). The sample results demonstrated that no petroleum-containing compounds were detected in the effluent water sample in exceedance of the regulatory limits, indicating that the POET system is functioning properly. Your analytical results of the pre-carbon, mid-carbon, and post-carbon filtration points are attached.

2 Mr. Axelsson and Ms. Porcella July 9, 201 Page 2 As you know, sampling of your water filtration system was conducted by Drake as part of a groundwater investigation being conducted in cooperation with the MDE and the Harford County Health Department. Drake would like to sample the water from your water filtration system again in the month of July as directed by the MDE. BC will contact you regarding the next round of sampling. Again, thank you for your patience and cooperation. If you have any questions regarding the enclosed test results feel free to call me at Very truly yours, Brown and Caldwell Carolyn Roth Project Manager cc: Eric Harvey, Drake, (via electronic submittal) Susan Bull, Maryland Department of the Environment (via and FedEx) Jeanette DeBartolomeo, Maryland Department of the Environment (via and FedEx) Peter Smith, Harford County Health Department (via and FedEx) Attachments (1) P:\Warren_Equities\Bel_Air_MD_Drake_Petro\1472_Bel_Air_MD\Reports\POET Letter\201_May\L07091(1_meadow_May_POET).docx
