RE: April 4th technical meeting on BWIP geology and hydrologic CGC: 4o -6otesting plans

Dear Russell,

The technical meeting was for the most part a rehashing of majorproject plans for the benefit of new participants. RHO gave theirusual slide shows and handed out copies of the view graphs

_ (attached). The locations of planned seismic and magnetic surveysare-shown in the attachments as well as well locations and types --

of tests planned. RHO did not go into a lot of detail. It seemsthere were conflicting meetings so the usual large DOE and RHOcontingent was not present. Dave Dahlem ran the meeting for DOEand most presentations were done by Sue Price, Steve Baker orSteve Strait.

Basically, what transpired was Bill Brewer argued with RHOconcerning the coincidence of earthquake swarms and structuralfeatures. He produced a set of maps with overlays which showedthe earthquake swarms located at triple junctures of knownfractures or faults. The faults and fractures were taken from U-2photos, Side Looking Airborne Radar (SLAR) and all other data thatBrewer had collected. I asked him for a set of maps but he didn'thave enough copies, so I think we should officially request them.(Draft request is attached.)

It appears that DOE and RHO have decided to fund the WashingtonState University (WSU) geophysical well logging-proposal. Itseems that Jeff Brown from Pullman will be involved, which seemedto please Brewer. Although details were not discussed, itappeared that the proposed work will be done by WSU, as opposed toRHO, but RHO may still be controlling the purse strings.

Brewer also requested a new higher resolution SLAR survey be doneon the Hanford site since the Texas sites were getting one. RHOseemed interested in this, possibly as a joint venture betweenWashington State and DOE.

' PDR

I took the opportunity to criticize the boundary conditions usedin the RHO model and the Interagency approach and mentioned thatour studies indicate the Yakima Valley to be geochemicallydistinct from the Pasco Basin. To my surprise, Baker agreed withmy statements. He said he also believed the Yakima Ridge was aground-water divide and agreed that the USGS use of Sadis Creekand areas in the Yakima Valley were not adequate for boundarycondition determination.

I also criticized the fact that RHO had extremely limited fieldmeasurements of head in deeper units outside the HanfordReservation. I also stated we considered field measurements ofboundary conditions to be mandatory to verifying flow pathpredictions. Baker asked if we expected RHO to ring the PascoBasin with wells. I stated that some wells would be necessary atkey locations but we did not expect a lot of them. They thenasked where I would place them. I said that modeling work couldbe undertaken to help determine optimal well locations and that wewould certainly like-to participate in these decisions. Theyseemed amenable to this. Therefore, we should undertake someadditional tasks to investigate these locations in next year'scontract.

Basically, my conclusions regarding the meeting are as follows:

1) It was productive from the standpoint that we got todiscuss some of our technical conclusions in the-EA whichwill influence site characterization work planned by RHO.

2) The presentations themselves did not tell'us anything newexcept locations of geophysical surveys.

3) It was also apparent that we need to get an RFP outquickly for a tectonics oriented firm to follow thegeology aspects more closely.

4) Some new contract tasks should be investigated for FY 86.

If you have any questions, please feel free to call.

Sincerely,

Linda Lehman

OVERALL OBJECTIVES AND GENERAL PLANS FOR FY86+

'iil

OBJECTIVES or PLANS

1. Determine location and dimensions ofhydrologic barrier.

Locate and drill 3 wells into thePriest Rapids for constant dischargepumping tests and hydrochemical analyses.

Assess need for additional wells forconstant discharge pumping tests on basisof initial tests.

Assess need for additional geophysicsand seismic data on basis of initialtests.

2. Determine present geologic andhydrologic characteristics.

Assess structure through boreholeverification

A. Structure Verification

1 to 3 boreholes to a maximum depthof 1500 feet

B. Age Determination of Last Activity

2-10 closely spaced boreholesthrough sediments

Assess hydraulic properties of thestructure through additional hydrologictesting at different scales.

3. Determine future geologic and hydrologic Develop conceptual and numerical models.characteristics.

4. Documentation of Results Compile status reports and update plans;compile final report.
