r. Howes asked about the volume of discharge per acre for well injection` <br /> . F S & w said it depends on the soil type, thumbnail is 5 gallons per square foot. <br /> Toni asked how much area is need for well injections? <br /> S &w said you would need a pipeline from the treatment to the discharge area and then a row of <br /> injection points with a pump at that location and a small pump house. It could easily fit within a <br /> surrounding neighborhood. <br /> Tom asked if extra treatment is needed for injection? <br /> S & w said here is but that cost is figured into this scenario. A.de-nitrifying Ater is needed at the <br /> treatment plan. <br /> Well injection is new in New England and Stearns and wheler is working to bring awareness to it <br /> through the Bamstable process. It may require hydro geological investigation. <br /> Torn asked how much investigation is needed to pin point a location? How much of that work i <br /> included in this proposal? Is there an adequate allowance in this proposal to prove a site is adequate <br /> for well injection? <br /> S&w said they included an amount in this scope to prove a site is adequate for any technology. This <br /> proposal represents their hest judgement for the arnount of work that will be needed for Mashpee. <br /> They included in their proposal installation of monitoring wells, soil samples, soil permeability, <br /> modeling for mounding of the entire area with projected flow. F <br /> . Stearns and wheler's time line shows the recommended plan being complete in July 2000 but the <br /> remaining SPA review is not complete until September.2 That is correct. <br /> . Torn asked them to discuss "the river" proposal further? <br /> S &w said in the town of Barnstable they did an evaluation of nitrogen loading in the 3 Bays area. <br /> They net with the 3 Bays Preservation citizens group and the idea of a big pipe scenario came about. <br /> The pose is to increase the flushing in the area, and pipe in water from Nantucket Sound to the top <br /> of the bay and increase the flushing. This would show immediate results, not in I -15 gears like other <br /> mitigation would. They then started to look at it in more detail: what size pipe and pumping system <br /> would it need? They looked at sizes, types and costs. Steams and W eler provided a capital cost for <br /> that proposal to Barnstable but they would need to look at the environmental feasibility of it. The cost <br /> would he significantly less than sewerxng significant areas of that watershed. The cost was greater than <br /> 10 million for the pipe. <br /> 'fora asked about the effects of introducing saltwater(from Nantucket Sound) into brackish water? <br /> S & w said that would have to be answered through an environmental study. <br /> . Worn said he slid not see a lot in the proposal about system pricing, cost allocation to households, to <br /> tax base. what is Stearns and wheler's approach and who would do that work? <br /> S & W said they have that expertise. On the engineering side, they can provide capital casts and <br /> operation and maintenance costs. They can also provide information on institutional alternatives: how <br /> does the costs get distributed to the users. "These will be tough decisions for the town. Steams and <br /> Meier has a lot of expertise in different ways it can be done. <br /> John said Mashpee expects a lot of commercial development participation. would Stearns and wh l r <br /> be prepared to work with them? <br /> They said very much so. Now is the time to begin to look at that so the commercial developers do not <br /> fee they are being"held hostage'. <br /> 3 <br />
