r <br /> y r <br /> JUNE 11, 199' <br /> TOWN ELMLL <br /> 'resent: Dennis Balzarinil., Toni Fdala <br /> Meeting convened at :20 p.m. <br /> NUMTES <br /> Dennis made a motion to accept the minutes of May 14, 1997. Torn seconded the <br /> motion. All members were in favor 2- <br /> Torn attended an interesting conference `New Tools for Waste Water Systems"", The State is <br /> moving towards allowing use of the revolving loan fund for small cluster systems. It used to be <br /> only for large plants. with 0 interest loans, the total payments are half of what they would be <br /> over 20 years with interest. <br /> JI)ennts suggested choosing a target area in town to do a pilot. Worn agrees with that approach <br /> but it will take time to pick an area. <br /> If the town moves to require de-nitrifying systems for new developments, the Sewer <br /> Commission can target a new development for de-nitrifying systems. <br /> Bennis asked if there are any systems better than j t de-nitrification,, a system that deals with <br /> virus or colifonn <br /> Toni responded that viruses orgy move about 200 ft. in the soil before they die. Coliform dies <br /> even quicker than that. If there was a system on a coastal bank that had a break out problem <br /> (water coming out of the side of he bank) it could possibly still have cliforrn in i . <br /> The biggest sources of bacteria in the river is road runoff. <br /> Currently no one has yet put together a model of the Mashpee River watershed to show were all <br /> the nitrogen is corning from, including biological sources. The Kv report emphasized leaf litter <br /> as a source. The old bogs, with ditches, collect leaf litter and it flows into the river They are kept <br /> open by Mosquito Control. The KV report suggested doing something to reduce leaf litter by <br /> cutting back the tress along the bank and plant it with grasses. The report also suggested Ming <br /> care of the road runoff. <br /> The Waquoit study has taken 9 years, $4 million and in 2 gears they may have some answers. <br /> Tom does not think Mashpee should wait that long before doing something. <br /> George Heufelder,Barnstable County Health Dept. Thinks the de-nitrify�g systems.do work but <br /> they are expensive. He does not want to tell people they have to use them if they can't prove <br /> how well they work. <br /> ".Torn said tp just adopt a town wide bylaw requin'ng de-nitrifying systems is probably not a good <br /> solution because each ernbayment has a load of nitrogen it can handle, each one has to be looked <br />
