MINUTES June 11, 1992 4 BOARD of HEALTH worth of pollution O rl "We have seen situations very similar to this one and in at least two instances in the more immedi- ate area. " "It was expected, in one of those areas, that the landfill was the problem so a hydrogeology study was per- formed. "Because of its location,, proximal to two ponds and their groundwater divided was very dynamic, most of the ni- trates in those areas were -scribed to cross circuiting of ones own septic system or a neighbors. " 'Periodically dif- ferent rain patterns during the year would shift either right across the well or slightly off the well explaining the wide degree of nitrates. " "The area we are talking about is near a pond so undoubtedly the groundwater flow in the area is in- fluenced by pond level. " "Another possible explanation is agricultural practices in the past however, that -is seemingly void .as most Of the. lots that were first tested came out with clean water then further down the road tested high in ni- trates. " i- trates. " "This would indicate between the time of major de- velopment, in that area and now, we have had some change in agricultural practices, 11 "It would be our contention at this point that the problem does not emanate from an agricultural practice that being, a cranberry bog. " ' 'Animal waste sewer- age practices are minimal in the area. " 'gone other possible explanation . is there have been limited soil borings to the point that could confirm there may be clay lenses, meaning the water may be drawing from the layer above that layor which is collecting sewerage. 11 w Mr. Greelish questioned Mr., Heufelder as to whether- the slightly elevated levels of sodium. found in the water levels could -have any correlation to the high nitrates counts Mr. Heufelder responded, sodium is very variable, as far as, sodium concentrations in wastewater and is difficult to trace. " Mr. Heufelder explained to residents the possible health risks- associated wit n'i trat' s and° available. options e t * A concerned resident qquestioned Nor. Rich as to the ap- proximate time frame water service could be brought down to service the -subdivision. , A. i Mr., Rich -responded, presently the management plan is in the process of- being updated. "The management plan will be completed some- time time this su mer. t1 R11 ter~ duality is our main priority. 11 'IT date we- have nothing on file which designates the antuitWoods subdivision as having water quality prob- lems. 11 "1 mould suggest the residents approach the. dater Commissioner's and inform thea of the water quality problems."
