gam. ' a3 - <br /> ry �I <br /> - � Mr. H. C. Winsor <br /> September 16. 1987 <br /> Page 6 <br /> Benzene concentrations are contoured on Figure 3. It appears that <br /> 711 the plume has migrated towards Well 12. Toluene concentrations <br /> exceeded the DHS action _level for drinking water in Wells W-1, W-2, <br /> and W-3. Xylene concentrations are above the DHS action level for <br /> drinking water in Wells W-2 and W-3. No action levels have been <br /> i F <br /> established for total fuel hydrocarbons. <br /> Table 3.
