STATE OF RHooE isLANo G PtevloENCE PLANTATIONS Executive CHAM 4Et Ptovf D ENCE A JOSEPH 4Amm Axv GovtaMCe January 14, 1981 Mr. Boyce Grier, Director Region I U.S. Nuclear Regulatory Commission 631 park Avenue King of prussia, pA 19406 f
Dear Mr. Grier:
I am enclosing for your information and consideration a variety of documents in response to questions raised by NRC and also in support of requests the State of Rhode Island has already or 4
is herein making to NRC with regard,to decommissioning of the UNC Recovery Systems plant in Wood River Junction.
A brief explanation of attachments and a number of specific action requests follow.
We would appreciate your earlies possible response to and action on these.
1.
Residential Well Testing:
Affected communities have requested tnat tney oe notid:.ec of any future NRC well testing before
~
it takes place.
This can be ccordinated through the Gcvernor's Office.
A number of additional residents have requested tes:s (See Attachment "A")
2.
School Wells:
Bud Crocker asked for state data on the testing nistory for the three schools located in the general vicinity of UNC Recovery Systems (See Attachment "3").
Also attached ("C") is an assessment of the potential of contamina-tion of these wells by UNC derived contaminants prepared by Herb Johnston of the Geological Survey.
As you will note, Mr. Johnston finds no potential for contamination due to major differences in hydraulic gradients and drainage basins.
3.
Municipal Wells:
Bud Crocker also asked for data on semi-annual state testing of Westerly's well fields.
I have for-l warded this request to appropriate officials.

Mr. Boyce Grier Page Two January 14, 1981 4.-
Deep Monitoring Well:
As Attachment "D" indicates, the State is of tne opinion that a " cable tool" type well should be driven to bedrock in the vicinity of the existing T-6 monitoring well.
Again, as indicated in "D", we feel there are significant advantages to drilling a " cable tool" type well; advantages which would accrue to all parties to this situation.
We urge NRC to insure that such a well is driven and that this is done as agreed at UNC expense.
As Attachment "E" indicates, there are compelling technical reasons for delaying the actual drilling of the well until -
after winter weather breaks in March.
According to USGS hydrologists, present sub-free:ing temperatures will have a significant negative impact on the quality of data that can be expected.
They have assured us that a delay in drilling will not compromise the public health.
5.
Additional Monitoring Wells Along Pawcatuck:
We urge NRC to require UNC Recovery Systems to sinx at least two additional monitoring wells within the presently defined contaminant plume along the banks of the Pawcatuck River.
These need not be large diameter or sophisticated in design.
One should be sunk to_a depth below the bottom _of the contaminant plume, while the oIher should extend about half way through the plume.
The purpose of these wells would be to provide early warning of any contamination flowing at levels of
-sufficient depth to have a potential of flowing under the river and contaminating ground water on the other side.
Wells of this sort should be an integral component of a public assurance program.
6.
Hydrologic Model'ing:
The State requests a status report on tne nycrologic evaluation being performed under NRC con-tract by Don L. Warner, Inc.
We would also appreciate earliest possible notification of the results of Dr. Warner's investigations.
7.
Examination of the Site for Additional' Sources of Radiological contamination:
Arter extensive ciscussions, 5 tate orricials came to tne conclusion in December that the most efficient means of locating additional contamination sources, if any exist, would be to first identify anomolies in NRC overflight data.
This data was obtained in August of 1979 under contract to the Department of Energy.
Unfortunately, as indicated in Attachment "F", we have found such severe defects in the aerial data as to render it for all practical purposes useless.
We strongly reco= mend, therefore, that at the very least-NRC have this aerial survev done again proueriv.
We would prefer, however, detailed and dependable data.a ground level surve it would produce more We

Mr.'Boyce Grier Page Three January 14, 1981 urge NRC to conduct such a survey as soon as possible.
8.
NRC's Draft Soil Decontamination Criteria:
A number of State agencies anc commissions nave oeen asked tc review
~
and comment on the draft submitted to the State on December 2.
We have also asked for comments from experts in our university j
system.
We will be forwarding comments as they are received i
and would be aided in this effert if we had a clearer idea as to the comment deadline NRC has La mind.
9.
Testing of the Pawcatuck River:
The State Department of Environmental Management is sampling aquatic vegetation above and below the UNC plant site, but does not have the capability to perform similar tests of river bottom sediments.
Since such testing would indicate whether the contaminant plume has had any cumulative impact on the river, it is important that it be done periodically.
We, therefore, strongly recommend that NRC test sediment samples from above and below the plume site for radiological and nitrate contamina-tion.
The State will collect and transmit these samples if this would be helpful.
10.
Indian Cedar Swame:
We do not believe that the potential for contamination of this off-site area is great.
- However, spot sampling and isotopic analysis of sediments and vegeta-tion would confirm this conclusion and do much to allay public fears.
We would urge NRC to perform necessary analyses.
The State will obtain a limited number of samples, if this is acceptable.
11.
Source of Fission Products:
We are aware that NRC has conducted an investigation of tne sources of fission contamination in UNC's lagoon wastes and the contaminant plume associated with lagoon leakage.
We would appreciate a status report on this l
investigation as soon as possible.
12.
Waste Processing and Packaging Investigation:
We are also" aware tnat NRC nas concuctec an investigation of problems with UNC's lagoon waste processing and packaging programs, particularly I
their quality assurance procedures.
The State is extremely anxious that transfer of lagoon wastes to approved disposal facilities begin again as soon as possible.
However, we cannot permit such transfer until we are satisfied that deficiencies which led to past problems have been identified and satis-factorily rectified.
It is, therefore, critical that NRC's investigation of this matter be expedited and that the State receive earliest possible notice of its results.
This request i
is of highest priority.

Mr.'Boyce Grier Page Four January 14, 1981 13.
Illegal Pumoing of Lagoon Wastes:
The State has conducted an independent interview of tne individual alleging illegal
? umping of UNC lagoon waste out onto the ground.
A transcript aas been forwarded to NRC in support of its formal investiga-tion of these allegations.
We would appreciate early notice of the results of your investigation.
We are also forwarding for your consideration (See Attachment "G") suggested testing procedures for obtaining physical evidence of pumping.
As you will note, we feel that it will be most productive to test for ions of aluminum,. calcium, potassium, sodium, flouride and nitrate, all of which we know to be present in high con-centrations in the lagoons.
14.
Development of a Long Range Decommissioning Strategy:
As I have incicatec in my letter of January 13, we nave requested a meeting with UNC within the next month to discuss their long range decommissioning plans.
We feel so strongly that such a meeting is necessarv at this time as to have made it a precondition for further shipment of wastes off site.
We strongly urge NRC to attend and participate in this meeting.
We would also wish to discuss with NRC representatives long range testing, monitoring and quality assurance efforts which NRC and the State can and will implement as an integral part of a decomdissioning program.
It would be highly-desirable in this regard to coordinate our efforts along compatible line's.
15.
Scheduling of a NRC Hearing:
The State does not believe tnat a formal NRC nearing on the UNC situation would be productive at this time.
However, we are of the strong opinion that such a hearing should be scheduled in the not too distant future when we have a clearer picture as to the direction the decommissioning process is likely to take, but have not gotton so far into that process that we are too late to influence its outcome.
In order to prepare in an orderly and cooperative fashion for a NRC hearing, we would appreciate it if NRC attorneys were made available to discuss the procedures necessary to initiate and conduct such a hearing with our Office of Attorney General.
Dan Schat, Esq. (401-274-4400) should be considered our contact point for this purpose.
I apologi:e for the considerable length of this letter, but feel that we have arrived at a juncture in dealing with this -matter where clarification of relatively few issues will allow us to expedite the decommissioning process to the benefit of all involved.
Where any of our questions or requests would be more properly directed to other NRC officials, I would request that you forward a copy of this letter to them.
I an available at (401) 277-2074 if I can clarify or amplify any of our points.

Dear Mr. Grant:
This is a response to your request, made at a meeting at the State House on December lith, for my commen: on the possibility that well 3.'
water supplies at three public schools might become contaminated by 7
was:e water that has leaked into ground water from lagoons at the United Nuclear Corporation plant at Wood River Junction. The schools V
in question are the Charlestown Elementary School on State Route 112 In Charlestown and the Chariho Regional High and Vocational Schools in Richmond.
2~
The flow direction of contaminants in ground water in the area of concern can be approximated from water table maps prepared by the USGS. These maps, prepared in cooperation with the Rhode Island Water Resources Board, are available in the following publication:::
\\t:5 1*~
" Ground Water Map of the Carolina quadrangle" Rhode Island Water Resources Board GWM 9 (1960)
" Availability of ground water in the lower Pawcatuck River basin, Rhode Island" USGS Water Supply Paper 2033 (1974)
~
Water level measurements made as part of an on going USGS-WRB cooper-ative study of ground-water development alternatives in several major ground water eservoirs in the Pawcatuck River basin indicate that no significant changes in water table configuration have occurred since the above ci:ed maps were done.
Ground water flows in the direction of the steepes: hydraulle rw ent (slope of the water table), from areas of high altitude to areu.icw al ti tude.
Natural gradients in :he Pawcatuck River basin cause g r od
~
water to flow toward, and into, nearby streams.
Al though natural ly water table gradients can be altered (:hereby changing flow direction)

by large withdrawals from wells, present net withdrawals-frem aquifers by wells in the Charlestown-Richmend area are far too small to have any significant effect en the configuration of the water table. (Most p.;
of the water pumped from wells in this area is returned to the ground nearby by way of septic systems, which results in little net withdrawal).
USGS water table maps show that the water table at the Charlho Regional schools is more than 10 feet above the nearby Pawcatuck River,and that 8
the water table at the UNC lagoens is about 10 feet above the river.
This means that ground water is flowing toward, and into, the river from both sides. Under the present regimen of pumping, there is no
- ~
possibIII y that well water at the Charlho schools could become centam-e inated by waste that has leaked from UNC lagcens.
in the case of the Charlestown Elementary School, there is no possibility
~ ~ "
whatsoever that the well water supplies could be centaminated by wastewater frem the UNC lagoens.
The school is situated in a com-E; pletely different drainage area, which has virtually no subsurface hydraulic connection with the UNC lagoon area.
E' Sincerely yours hI

SUBJECT:
United Nuclear Cor:: oration Monitoring Well It has been agreed by the ecm=ittee to sttidy groundwater monitoring at the Lhited Nuclear Corpora:icn site in Charlestown, Rhode Island that a monitoring well will be installed by LWC in the vicinity of existing well T-6.
The new well will extend to bedrock or to a depth of at least 200 feet. There are at least two methods of installing this well (the hydraulic rotary me:hed and the cable tool methed); how-ever, the comittee did not reccmend the methed of ccnstruc icn.
Our objective with this well is to obtain approximately 1 gallen water sa=ples and approximately 1 quar sediment sa:ples that are representatives for the depth frcm which they are taken. The samples should be taken at about 10 foot inte:vals through the :ene of contam-inatien and at 15 to 20 foot inte:vals below the :ene of contard.natien.
.The sampling intervals should be Adjusted or additional samples collec-ted at major changes in lithology.
Problems that are likely to be encounted with the hydraulic rotary methed such as removing the drilling mud that. invades the fe=atien, plugging the sampling well point sc een and preventing drilling mud from entering the sample pipe instead of the groundwater cu weigh the speed and cost advantage of the rotary method. The cable tool per-cussien d-illing method gives a better record of the fe:=ation and the
- rim amcunt of water added shculd be relatively easy to pu=p out before sa=pling.
l It is therefore requisted that United Nuclear Corpora:icn be re-l qu:. red to install the groundwater monitoring well in the vicinity of existing well T-6 by means of the cable tool method. Mr. Kenneth L.
Kipp, hydrologist for the U.S. Depawent of the Interior, has requested Michael Powers of Goldberg, Zoino and Associates, Geohydrological Censultant to UNC, to develop specifications for well reccccending the cable tool method of ccnstn:ction. A copy of Mr. Kipp's letter is attached.

Dear Mr. Powers:
As agreed in our telephone conversation last week, I a= sending this let:er briefly describi=g our desires for the specifica: ions for che well to be dr led by UNC a: the ~4 cod River Junc:1on si:e.
Our objective wi:h this well is :o obtain large volume (approxi=ately 1 gallon) wa:er sa=ples :ha: are represen:ative of the ground water at the depths from which they are taken and to also obtain represen:a:1ve sedime== samples (approxima:ely 1 quar ) a: the same depths.
We would like to have sediment and water samples from about 10 foo: Etervals down through the zone of ground-water con: amination and 15-20 foot~ intervals below the zone. At those depths where i: 15'not possible te pump'a water sample, only a sedimes sample would be necessary.
Adjustment of ene sampling depths or addi:icnal samples would be desirable at major changes h lithology.
Our preference is for a percussion or cable cool drilled hole over a hydraulic rotary hole wi:h dr1111=g mud.
Although the drilling procedure is fascar with a rotary rig, the difficulties in removi=g the mud tha:
hvades the formation, the possibd'dty of plugging :he sampling well point screen with drilling mud duri=g installation, the problem of preve= ting dr1111=g - d from preferen:1 ally entering the sampling pipe instead of forma: ion water, an.1-:he possibili:y that bacteria is :he drilling mud may reduce the nitrate concen::at on, outweigh the speed and d
l cost advantage'of rotary drilling.
Cable cool percussion drilling gives I
a better record of :he formations and the =hd - amount of water added should be relatively easy to pump out before sampling.
A preferred i
method of wa:er sampling would be to inser: a 2" well poin: below the bot:om of the casing and use an inflatable packer to seal off the column of water in the well before pump 1=g a ground water sample. The USGS could probably provide the packar for 8" and 6" casing. We would like 1
- o. experiment wi:h :he addi: ion of a tracer such as li:hium chlorida to the va:er which is added to the hole in order to ge: some idea of how much residual added wa:er is presen: in a given sample.
It would also be I
nice to perform condue:1vi:7 and =1::a:e analyses at the d:di' 4g sica to :all when we have emerged fro = the bot:om of the con-"42:ed zone.

Mr. Malcolm Grant M
Governor's Office Office of Policy and Progran Review State House Prosidence, Rhode Island 02903 Dea Mr. Grant:
Specifications for drilling a deep test well at the United Nuclear Corporation plant at Wood River Junction are being prepared by UNC's ground-water consultan: Mike Powers of Goldberg Zoino Associates.
Mike says he is presently planning to request that the test well be completed during February,1981, because of UNC's desire to complete the well as soon as possible.-
Ken Kipp, a USGS research hydrolo' gist who plans to be present to collect samples when the well is drilled, has expressed concern that snew storms and subfree::ing temperatures may severely hamper sampling operations and adversely affect the quality of data obtained.
! h.-
If at all possible, he would prefer that the hole be drilled no scener than March or April, 1981.
S
!~ d A substantial amcunt of time and money will be invested in this l [.
tes well.
In our Judgment, this investment should not be compromised by doing the fieldwork in weather that is likely to affect the quality of information obtained.
I have talked with il*
Bob Gregg, UNC plant manager, about cur concerns. He is willing to postpene drilling until af ter February as long as UNC is not I
held responsible for the delay.
The primary purpose of this well is to determine the depth of grcund water centamination; a secondary purpose of the well is to determine l
whether centaminants are present in fine grained sediments, where they may be moving more slowly than in coarser sediments. This informa:len will enable us to better determine the total volume of contaminated ground water present and to be::er determine the time it will take fer contaminants to flush from all sediments.
If this well were nc; drilled, it would simply make it more difficult to predic:- flushing time.
Delay in drilling the well, therefere, poses no additional risk with regard to public health.

SUBJECT:
United Nuclear Corcoration The report of " Aerial Radiological Survey of the area st: rounding the United Nuclear Corporation Recove:y System Facility", prepared by the United States Depart: ent of Energy dated August 1979, has been reviewed. This aerial survey only included half of the UNC property.
One portion of the repor: (abstract) is stated that the survey consist of flying north south, lines spaced 60 meters apart. Another portion of the report indicates the flight lines were oriented in a east west direction. These two statements are inconsistent. The report indicates that increase in levels of radioactivity were found in the nor-J: west corner of the site.
The levels of radioactivity found in the north-west corner were reported to be the Icwest found, apparently below background for the area. Elevated activity appears to have been found near the gravel bank in the northeast corner of the area.
Because of these inconsistencies, it is felt that the report has little value.
It is recommended that another survey be under-den covering the entire property of United Nuclear Corporation.
