STATUS OF EXISTING SYSTEI�IS ' <br /> The SBMA encompasses 82 houses, cottages , or other habitable buildings . <br /> Of these 82, approximately 40 were inspected by me during 1978. Ttao <br /> systems were found to be unquestionably non-conforming (outhouses) . <br /> The great majority of the balance were substandard either in location <br /> near wells or seasonal water table, or in size of drainfield. The <br /> remaining systems not yet inspected are scheduled for inspection in <br /> rsay, 1979. � - <br /> • TABLE 1 - STATUS OF DtISTING SYST�iS ' <br /> STR:ET 2'J,?SE h'lI.�ER OF HOUSFS ;IL"3ER I1:SPEGTD COh'FOR*iING SIJBSTAh'DARD NON-CONFOR'lING <br /> Tonkava Road 0 0 0 0 0 <br /> West Iake Street 13 1 1 - - <br /> Eaet Iake Street 9 9 � 0 7 2 <br /> Leaf Street 1 0 - - - <br /> Crestviev Avenue 14 13 - 13 - <br /> Tonica Avenue 9 9 0 9 0 <br /> Eileen Street 2 1 1 - - <br /> Bayside Raad ^ � 30 ' 1 1 - - <br /> Bedervood Raad 4 2 - 2 - <br /> 82 � 36 3 ' 31 2 <br /> Kriown non-conforming systems are circled in red on the attached map. <br /> Essentially all the East Lake Street houses are non-conforming according <br /> � to the Statewide Shoreland Management requirements. A 1974 study by <br /> McCombs-Knutson Associates analyzed ground and surface water samples <br /> from various locations in the Tonka Avenue-Crestview Avenue-East Lake <br /> Street area. Shallow groundwater samples. showed high concentrations <br /> of chloride and surfactants, indicating contamination, Surface water <br /> samples from� the unnamed tributary to Stubbs Bay had a high fecal <br /> • coliform count, indicating pollution from individual �on-site systems. <br /> The report recommended sanitary facilities be constructed. <br />
