~ ; , Steve Lee (MPCA) explained that In 1981, PCA became aware of the well contam- Ination and began a ground water study to determine the cause and who was affected. Lee said the money is now in hand and the study Is going forward. Lee explained that various levels of wel I contamination were detected In the triangle area, 7 badly contaminated: 3 In New Brighton 4 i n Arden HI II s 24 wells have low level contamination (cons i dered usab Ie potab I e water)., Lee explained EPA conducted a feasibility study which was completed the end of June, which would provide a temporary water system by means of a 4" watermaln; noted that PCA recommends a main large enough to provide fire lines; the 12"/8" watermaln pro- . posed Is currently being considered in Chicago and Washington, D.C.; believes EPA wi I I fund 6" and probably 12"; do not have a final decision on this. Questions and Comments from the Floor Mr. Harry Werllen, 4647 Highway 10, said he works for the City of St. Anthony; stated we only want water to our houses; do not need to pay for a 12" line; al I we need is an 8" main. Christoffersen explained that the 12" line coincides with the master plan; noted that the pressure loss is greater in a smaller line; feels It is desirable to main- tain pressure for fire protection purposes. Mr. Werllen said there is no reason for a 12" line; 8" mains service St. Anthony. Christoffersen noted that the proposed water line is not looped. Mr. Richard De Witt, 4651 Highway 10, said the original proposal was a 6" main. Lee said a 6" main would meet State Code. De Witt asked If service lane will be torn up. Christoffersen said that part of It wi II be; construction wi II be as far off the paved surface as possible, but In the street right-of-way. Christoffersen explained the improvement proposed Is the same plan proposed in 1980. It was explained that Arden Manor Mobile Home Park Has no fire protection from Its own system; fire trucks wil I have to obtain water from the City hydrant system on trucks. It was noted that an emergency connection can be made at the Prior Avenue entrance to Arden Manor (north side of Highway 96). Jeanne Winiecki, 4471 Highway 10, asked If the source of the well contamination has been determined. Lee indicated (on a map of the area) the several sources of contamination In the arsenal (hi I I, Building 502 and the north side, etc.); also noted the approximate location of the most highly contaminated wells In New Brighton and Arden Hil Is. Lee said "trace levels" have been found In two wells south of Highway 96; noted that the trace levels found south of Highway 96 do not meet health criteria for contamination (water Is considered usable). Jim Breske, 4659 Highway 10, said he Is concerned about aval lability ~f ambulance service during construction; explained he is on kidney dialysis; reported that he hooked up to the Arden Manor water system when his wel I was found to be contaminated. Breske asked If he would have assessments for the proposed improvement if he is hooked up to Arden Manor water system. . -2-
