-2- Ms . Brustman distributed two MPCA informational sheets to all present in which the historical background of the discovery of the ground water problems affecting the water supplies in �Arden Hills, .New Brighton, and St. Anthony was given along with recommendations from CH2M Hill for temporary City -action should the levels of 'contamination increase to an undesirable level. The study recommended the City should continue to closely monitor the quality of- the water;.. plan for . implementation of permanent means of obtaining clean. water; adoption of a water conserva- tion program in case a well has to be closed; and in the event two wells should have to be taken off line, and conservation doesn ' t provide adequate drinking water, immediately .implement one of the temporary measures . suggested by the engineers . These options and- their costs were discussed by Mr. Schilling who reiterated it would be much less expensive for the City to tie-in to the Roseville water system than with that of Columbia Heights or to install either an air stripping or carbon filtra- tion system, or combination of both, on the existing wells. Drawbacks of the latter two options were explored at length with ' the engineer who said his firm's experience with the air stripping filter system in Tacoma .had been .that the discharge of -pollutants from the stacks had been pretty well diluted and widely dispersed but the cost of the system itself is prohibitive for this purpose , and the cost and difficulty of disposing of the carbon made the, operation and maintenance costs of the carbon filtration system very expensive. Frank Budnicki , 3124 Wilson N.E. , asked whether it' had been determined which direction' the underground water flowed in this area and was told that generally , water could be expected to flow from northeast to southwest, but pumping could divert some of the flow. Mr. Lee assured him that after the two year study in which wells would be sunk at various points there should be a more definitive answer to his question upon which the City could base a permanent solution. Mayor Sundland indicated he perceived that the Council was working on the assumption that contaminant levels in the City wells would increase and, since both Roseville and St. Paul, who provides the water for Roseville, had indicated to Mr. Schilling they would be amenable to continuing a discussion with St. Anthony about the possibility of the City connecting with their water system on a temporary basis , believes there is a general consensus on the Council that a discussion should be initiated with the officials of both cities to determine the possibility of St. Anthony making both a temporary and permanent connection to their water system in the event the City ' s drinking water becomes unsafe to drink. The hearing was closed at 8 : 19 P.M. Rosemary Franzese was present to report to the Council the actions taken by the Planning Commission during 'their June 21st meeting as reflected in the minutes for that meeting. At 8: 20 P.M. the Mayor opened a public hearing on the request from Arkand Partnership for approval of a Planned- Unit Development Concept Plan for Phase'. 1 -.of the Kenzie Terrace Redevelopment Project which the Commission had recommended the Council approve as presented.
