1 <br /> The bevels of contamination continue to be confusing, the high <br /> levels in Well 4 could indicate a source to the west of our <br /> site. <br /> We find the groundwater flow to be to the southeast at a <br /> gradient of 0 0033 Ft/Ft The gradient has remained fairly <br /> steady fluctuating between N30E and S50 E since April 1992. <br /> On April S, 1993, we measured the hydraulic conductivity of <br /> the wells at the site We did this by performing slug tests <br /> on 3 wells, see Table IV and Fig. 2 At each well we lowered <br /> a transducer below the water table and recorded the static <br /> water level relative to the transducer. We set the transducer <br /> to read feet of water. We then poured 5 gallons of tap water <br /> into the well as quickly as possible and started the data <br /> logger to record the readings from the transducer We <br /> processed the data and plotted it in Log form according to the <br />► <br /> Brower and Rice Slug Test, a copy is attached <br /> We found the hydraulic conductivity at the site to average <br /> 5. 71 Ft/day. The average porosity is 0 3 and this taken <br /> with the gradient indicates the velocity of the water at the <br /> site is 0. 06 Ft/day. <br />► <br /> IMOINQ _LIZI9I <br /> �v t tor.1jfeV4 <br /> Q 't �d <br /> nr <br /> Quarterly monitoring will continue ?�+ c5' Tv <br />►� NO 01979 <br /> Yours truly, Expires <br /> � Sam <br /> L p�' CAL�4 <br /> John Cussen <br /> Reg.
