detected in that well from 1999-2010. There is a new emerging contaminant found in the groundwater, in and around the ponds, known as perfluorinated compounds (PFC's). The EPA has set an advisory level of 0.07 ug/L for PFC's. Some properties, down gradient of the plumes and ponds with potable wells, have been identified with elevated levels of PFC's. The military is providing bottled water and installing granulated activated carbon filtration systems to those properties. Both VOC and PFC testing is recommended by the military should the Board of Health approve the irrigation well. Tom Desmond of Desmond Well Drilling, representing 130 Wheeler Road, introduced himself to the Board. Mr. Desmond stated that this is an installation for an irrigation well. The irrigation well will be used primarily to irrigate the lawn and water the bushes on the property. Lucy Burton made a motion that the Board of Health approve the irrigation well at 130 Wheeler Road with the condition that there is annual testing of the irrigation well water for PFC's and VOC's and a Deed Restriction placed on the property. If contaminants are found above the allowable limits, then the well will be decommissioned at the homeowner's expense. Brian Baumgaertel seconded the motion. The motion was unanimously approved. 7:55 PM — Commercial Site and Septic Plan Review--61 Echo Road. Raul Lizardi-Rivera of Holmes and McGrath, representing 61 Echo Road, introduced himself to the Board. Mr. Lizardi-Rivera commented that the proposed site development is for an electrical company and used primarily by the owner, Driscoll Electric. The front of the building will be office use for the electric company, and the rear of the building to be leased and used as a warehouse. The proposed septic system will be located at the front of the property. A two-compartment septic tank is proposed along with a primary leaching field and a reserve area. At the rear of the property will be a holding tank for the warehouse portion of the building, and floor drains will also be installed in the warehouse. Glen Harrington remarked that his industrial tight tank recommendations have been included to the Board of Health Commercial Requirements. The additional requirements are: 1. A plumbing permit for tight tank installation. 2. The tank should be sealed to insure water tightness. 3. Concrete tanks shall be a monolithic-type construction. 4. The tanks shall be tested watertight by holding a full level of liquid for a minimum of 24 hours and be witnessed by the Plumbing Inspector or an Agent of the Board of Health. Lucy Burton made a motion that the Board of Health approve the Site and Septic Plan for 61 Echo Road with the condition that all of the Mashpee Board of Health Requirements for Commercial Buildings are included. Brian Baumgaertel seconded the motion. The motion was unanimously approved. 8:00 —Commercialliindustriial Site Plan & Septic Review—29 Echo Road. Raul Lizardi-Rivera of Holmes and McGrath, representing 29 Echo Road, introduced himself to the Board. Mr. Lizardi-Rivera stated that this project is a small 1500-square foot building. The septic system is proposed to be in the rear of the property. A two-compartment septic tank along with a primary leaching area and a reserve area are proposed. These two leaching areas will be installed at the same time. Glen Harrington remarked that his comments to the Zoning Board of Appeals for the Special Permit a year ago were: "The plan meets the minimum requirements for Title V. If the facility becomes a dispensary for recreational marijuana, the use is expected to substantially increase so installing a larger leaching facility now is recommended. The reserve area will also be installed at the same time as the primary so there is a failsafe built into the situation". 2
