Andrew, 1 hope you had & good I'haaksgivingr. That is not exactly what we are aslcing for. ,^ 5W[ ff' / ) j[ 1. we don't need additional aape. We need the XT locations of each eanpUng point, The beat way to present this is a table of well and/soil/flanple ID nuirbers in one column and their location in the aexe^-ed'lumn, Location should be las/long, TOt, or the Ohio State Plane Coordinates or sane other reference system that can be tied toto one of the standard coordinate systems. If you don't have the locations tied to a Standard coordinate system then elevation Mid feet (or mtarst MBting aad neifthiog would do a.s long as the plant release loeationa are in the Bane system. y.,^^^","f&'fv If you don't have the locations then please tell ua how you located the wells on the saps that you have suhmittafl. HE the locations wave not surveyed or found by GpS than the beat info you have would be O.K. as it long as allows us to map fcb locations as wall aa thsy are known, If you have the data ia a QIS format, arcview Eor example, that would be useful. We don't have autocad. itf What we want is the raw info that is needed make naps of measured concentrations fron well and soil ssiHplea. we want to be able to nuilse our own ttspa and to run geostatt on th data to evaluate nodel pradietione and to look tor Crenda. [)< W ^_ <^ 2. You presented a table with groundwater coneantratloas ia ona \ coluiim and the predicted air coneantratione in another.

We also need all the aodel inputs, including aeteorology data, geographic inputs, relMse estimates, eheBi propartiea, ate that were used to run the model. A list of all cha inputs used In each model run along with a sentence or two explaining how they wer chosen and what assumptions wera used would be the bast. At tha least we need to sea the input filae so 'WB cwt 686 how tha modgis were run. Similarly, we need to see the raw iKx3el outputs. We need fcp be able to confirm that the model ran correctly and the results are reproducible. Wft also nfeed to be able to make contour maps of the predicted concentrations, and to run statistical analysis of; the model outputs and the measured concentrationB / i S<A9 5<At'OZ.'"'Avft 0 ? r I ~ nQof^i-.

For clarification, I'm going to BUBtniaEize whaiC intormation you ara requesting to conduct an evalutltioa of air wnisiens verB-uB gro'undwKta;)? eonoentratione near Wash Worka. You would like the following information; A map displayin0 gyoundwater aanpling Ideations. I will incltldB isapa foe both the WV oEf-Bittt 0-2 aile radivB and the Ohio 0-2 mile radius. .dwg* >?Do you want this as an Autocad Eilft or same otb foisaafc (i.e., Excel spreadsheets that includa all of the data tor the locations displayed on the maps. Air modal input/output Cor modeled yvac 2000? re this correct, or do you want other modeled years ithe groundwater data is for year 2002)? I'a not sure what format I can gat the output data in, but will circle witti the air modeling team. it As soon as we resolve some of these Questions together and sent to you (on CD likely) asap. no later than Thursday. I can get the infoonation Hopefully you can have Thanks. .Andrew ASH027122 EID780402 EID780402 This coMMUnication is tws use ty thft intended recipient and contains information that Bay b privileged, eolElfideatial or eopyrigbtefl tiftder appli cable lav.
