PROJECT AUTHORIZATION A proposal requested by GPU's Nuclear Environmental Controls Group-TMI was submitted by Ground / Water Technology, Inc. on April 7, 1981 for a hydrologic and geologic inve,stigation at the Saxton Nuclear Experimental Station, Saxton, Pennsylvania. This proposal included the following scope of services:
- 1. Assemble available technical literature and well 1 logs.
- 2. Conduct a_ detailed geological reconnaissance of 1 the s~ite and its immediate vicinity.
- 3. Review environmental reports, construction draw- )
ings and interview former employees to aid in the - evaluation of the influences of plant construction on the subsurface soils, rock and water environment.
- 4. Drill test borings, collect samples and install .
permanent devices which would allow for procure-ment of high quality groundwater samples and the j determination of groundwater levels.
- 5. Prepare a written report summarizing our activi-ties and giving a synopsis of the hydrogeological environment of the site. This report would also J
present our assessinent cf the probability of of f- i site migration of groundwater ~ based upon the geo- j logic research and field vrork included in this j program. ) 1 During a telephone communication with Dr. Martin McBride, ! (Project Lead, Nuclear Environmental Controls Group) the above scope of work was authorized, with the exception of the de- l tailed geologic reconnaisance'and the installation of ground-
]
water samplers /piezometers. Subsequently, after the completion l
.of the drilling program, the geological reconnaissance was i authorized.
PROJECT DESCRIPTION On May 7, 1981 Environmental Controls Group, and Ground / Water Technology personnel visited the site with personnel previous-ly assigned to the Saxton tate in order to select drilling locations. On the follow'.ng day, Ground / Water Technology.per-sonnel. visited the officss of the Pennsylvania State Geologist and the United States Geological Survey offices ( er Resource amo an newamc
2 Branch) located in Harrisburg, Pennsylvania. Both offices were able to provide geologic and hydrologic materials de-i scribing the Saxton site region. During the per.iod of May , 12 to May 22, 1981 drilling, sampling and rock pressure tests { were conducted at the Saxton site. During subsequent weeks,
- geologic research and laboratory testing of selected samples were completed.
SITE LOCATION AND DESCRIPTION The Saxton Nuclear Experimental Station, located in Bedford
-County, is situated in the valley of the Rayston Branch of the l Juniata River (Figure.1). The river meanders along 'ts i water-course while the overall flow direction is to the northeast.
- This river valley is border.ed on the northwest by A11egrippis
] Ridge and to the southeast by Terrace Mountain. The relief , from the river to the ridge tops exceeds 500 feet. l 4 The Saxton Nuclear Experimental Station was built a'djacent to an existing coal-fired generating station (Figure 2). The nuclear reactor had produced energy which ran the steam plant's generator. At present-the. coal-fired plant has been demolished 4 and Saxton Nuclear Experimental Station has been deactivated, and most of its structures remain. TEST BORING LOCATIONS Of primary interest in siting of test borings were the con-tainment structure and the radwaste treatment plant. The foundation of the containment structure was excavated into the bedrock to about 50 feet below ground surface. The rad-waste treatment plant facility was also founded in the bedrock with its deepest point being'about 25' feet below ground surface. Two test borings were drilled into rock near each of the above structures (Figure 2) to radiologically survey and test extrac-ted soil.and rock materials (B-2 through B-5). Test boring (B-1) on the east side of the site was also drilled into rock gomewe acecc.m:

Soil borings were also completed to supplement the above test I borings. Borings B-6 and B-7 were drilled to the top of rock in the vicinity of the radwaste treatment plant. B-6 was lo-cated approximately 25 feet west of the plant. B-7 was located as close as possible to the north side of the plant. i Two hand-dug pits were located just north of the reactor (GS-1 and GS-2). The pits were dug to a depth of 4 and 6 feet re-spectively. Soil samples were collected for both radiological testing and grain size gradation tests (see Appendix B). SOIL, ROCK AND GROUNDWATER SAMPLE ACQUISITION A CME-55 test boring rig was used to obtain split-spoon samples and to core the bedrock (NWX core). Generally, soils and rock were sampled continuously over the. full depth of borings B-1 and B-7. To prevent the possibility of any form of cross-contamination, samples were placed in separate plastic bags. The split-spoon sample barrel used to sample soils was washed with tap water, cleaned with a detergent, and rinsed with tap water after each sample was removed. The rock core barrel was also rinsed with tap water after each rock core was removed from the bore hole. When the rock core sampling portion was completed, the bore hole was pumped (generally about a half hour) to remove re-circulating water and to obtain a groundwater sample. On se-lected borings packer tests (rock pressure testing) were then undertaken. Upon completion of each boring, the hole was
, sealed with cement grout.
6 SOIL DESCRIPTION Split-spoon samples collected during the drilling program and samples from hand-dug pits near the reactor indicate that the surficial soil near the buildings is comprised of two types of construction backfill: (1) well graded reddish silty fine to coarse sand with some fine to medium gravel and (2) a well graded mixture of ash and cinders. Boring logs are presented in Appendix A. Both of these fill materials were reported placed during station construction. Laboratory mechanical analy-ses were performed on both the silty sands and the ash. The gradation curves of these materials are presented in Appendix B. The thickness of the fill generally ranges from 3 to 6 feet, although the fill may be thicker at locations where building construction excavation took place (e.g. waste treatment facility --see boring B-6). Underlying the fill materials is a boulder layer which was en-countered in the majority of the borings. ,This layer is gen-erally 4 to 6 feet thick and separates the fill material from the top of the bedrock. To sample the boulder layer NWX coring was attempted. Although samples of the boulders could be re-covered by this technique, the drilling fluid tended to wash away the fine materials in the interstices between the boulders. However, in a few of the core samples, some silty clay remained between the boulders and is therefore assumed to be the material making up the boulder matrix. The core samples indicate that the silt and clay was localized in the boulder layer and did not appear to be present in the fractured bedrock below that zone. BEDROCK GEOLOGY The geologic map of Pennsylvania (1:250,000 scale) compiled by the Pennsylvania Geologic Survey, Fourth Series (1960) identifies the bedrock material underlying the Saxton Experi-mental Nuclear Station as " marine beds" of upper Devonian age. These rocks,are described as gray to olive brown shales, gray-wackesN and sandstones. Geologic worksheets,.which will be the Q cxuow ncwom.wc
7 product of a future detailed state geologic map, were reviewed at the Pennsylvania State Geologist's office. These worksheets indicate that the area in the vicinity of the Saxton site will be identified as the "Foreknobs Formation", upper Devonian age, mapped by J.M. Dennison in 1970. He describes this formation as gray alternating sandstone and siltstone with red beds. Observations of the geology at road cuts.<in the area between Breezewood and Saxton, pennsylvania indicate that the paleozoic rocks of this area are folded, being a product of a mountain building event occurring probably during the late Devonian and continuing to the end of the Permian period. These road cuts show alternating layers of siltstone and sandstone beds with I red beds. Typical cross sections through the Appalachian Mountains of Pennsylvania depicted on.the geologic map of Pennsylvania in-dicate that the geology of this region is typically a series of major folds referred to as anticlines and synclines. Figure 3 is a sketch showing an idealized anticline and syncline. Since the geologic map of Pennsylvania does not specifically draw a cross section through the plant site, a geologic cross section was constructed through this region (Figure 4). This geologic cross section is drawn at a northwest-southeast orien-tation (Figure 1) and indic'tes a that the Saxton Nuclear Experi-mental Station is constructed on the limb of a major syncline that dips generally towards the east. A review of Pennsylvan'ia geologic literature indicates that the nearest location to the plant site where a published geo-logic study has been conducted is the Broad-Top Coal Fields, approximately five miles to the east. This report entitled, "The Broad-Top Coal Fields," by James H. ~ Garner was published in 1913 as Topographic and Geologic Survey of Pennsylvania Report #10. In this report, the Sroad-Top Coal Field is identified as the general axis of the syncline.

10 During the geologic, reconnaissance many bedrock outcrops were examined throughout the region. These outcrops sub-stantiate the premise that.the plant site is located on the western limb of a major syncline which strikes generally N 250 - 420E and dips approximately 150 - 450E. Some minor internal folding is present within various bedding members though the overall dip of the major structure is to the east. The fracture fabric of these Devonian rocks was also examined throughout the area. A well developed major fracture pattern occurs in most of the outcrops which strikes from N_500 - 75 0W and dips nearly vertical. A second poorly developed fracture set trends along the approximate line of the strike of the bed-ding and typically dips 450 - 600 to the west. GROUNDWATER IN THE PIPE TUNNEL AND~THE RADWASTE BUILDING During the initial site visit we observed the presence of water I both in the pipe tunnel and the radwaste treatment plant. The site representative informed us that, during certain times while the station was operational, water would bubble up through the joint between the pipe tunnel and the containment shell and would drain through the tunnel into the radwaste treatment plant. At that time, water in that facility was reportedly controlled by pumping.from the basement sump. Construction drawings indicate that the surface grade at the pipe tunnel is approximately 811 feet above msl and that the floor of the pipe tunnel is approximately 803 feet above ms1. i If we assume a groundwater elevation of about'807 feet (the average groundwater level observed during this boring program i was 3 to 5 feet below grade), then approximately 4 feet of l water should be present in the pipe tunnel. Since the rad-waste treatment plant is constructed predominantly below grade, ground water will drain from the pipe tunnel towards this " sink" during peri,ods when water is entering this constructed system. It would be expected that, during periods of high groundwater levels, water will enter the tunnel and recharge " sink" at HOTTER TECHNCL7sVlNf"
11 1 the radwaste treatment plant. Since the groundwater level fluctuates, during the drier portions of the hydrologic year water in the tunnel may actually re-enter the groundwater regime. l The higher water level in the pipe tunnel and the radwaste treat-l ment plant could, during the dry season, force water from the i structures back out thro'6gh zones which may not be water tight, such as the observed joint at the containment-tunnel junction. i HYDROGEOLOGIC SETTING l One of the objectives of this investigation was to characterize the subsurface stratigraphy as an aid in assessing the hydro-geology of the site. There are three distinct subsurface zones { which have different waterbearing and transmitting properties. ! l These zones are as follows:
- 1. A construction fill material, comprised of well 1 graded silty fine to coarse sand with some gravel 1 ash or cinders.
- 2. A boulder layer with silty clay in the interstices.
1
- 3. The bedrock of grey siltstones, sandstones and red !
beds. I During the drilling of the test borings, the groundwater level was measured at depths of about 3 to 5 feet. These measure-ments probably repre ant an average of the piezometric levels in the three subsurface zones, j i
. k TESTING RESULTS l
In order to obtain a relative indication of the ability of the ! various subsurface zones to transport groundwater, field per-meability tests were conducted in selected bore holes and labora-tory mechanical analyses were performed on construction fill-materials. Due to the nature of the rock coring technique, it was difficult to recover a good representative sample in the~ boulder-clay deposit. It is presumed that the clay retards groundwater flow, probably making the stratum relatively im-pervious. , h aouemmancovnc

. Mechanical (sieve) analyses were performed on two samples of.the red silty sand fill and on a sample of ash fill (refer.to Appendix B for results). A large portion of the {
red silty sand fill material was finer than the #200 sieve. ] Hydrometer tests were performed on these two samples to obtain the gradation of the fine-grained materials. Both samples were well-graded, containing about 45 percent pas-sing the #200 sieve. The well-graded nature of the fill suggests a very low permeability probably ranging between 10-6 cm/see to 10-8 cm/sec. Although it was_possible to perform a mechanical analysis on the ash fill material, the. validity of.the results is question-
- able since the friable particles may have been altered by the sieving action. However, visual examina' tion'in the field sug-l gests that this material has substantially greater permea-bility than the red' silty sand fill.
Packer tests (rock pressure tests) were conducted in bedrock at borings B-3, B-4, and B-5 to determine the apparent permen-bility of the bedrock. This field test entails pumping water' under pressure into selected sections of the bore hole isolated by pneumatic packers. The packer test apparatus used had a l test section of 6 feet between the upper and lower packer, f The test results (Appendix C) indicate a substantial range in i rock permeability, ranging from moderate values (about 1.06 x f 10-3 cm/sec) to negligible values (no flow recorded in the test section). The test results were compared with the RQD (rock quality designation) values obtained during the coring j of each test section to determine if RQD could be used as a [ reliable indicator for zones of high permeability. It appears { that a reasonably good correlation does exist between higher
-permeability and. low RQD. I The different bore holes show some similarities with respect '
j to RQD values. A zone of very low RQD values exists near the j top of the " natural" bedrock surface and is considered to be j- a weathered erosiona'l plane (Table 1). This premise i~s also 3-supported by the packer test results, indicating higher GRCAND WMTER TECWACGv N

14 permeability. values in this zone. Another zone of low RQD values occured at a depth between 40 and 50 feet below ground surface in borings B-3 and B-5. These low RQD values may be accounted for in two ways; (1) the zone may have been created during th'e construction of the reactor or (2) the zone may I be a naturally occurring more permeable layer. Since there is no evidence of construction excavation to depths of 40 or 50 feet at these locations, the low RQD values are attributed to a naturally occurring zone of higher permeability. Con-tinuity of this zone in the bedrock is inferred, since B-3 and.B-5 were drilled along the-strike of the bedding and since these zones are at approximately the same structural elevation
'in each boring.
CONCLUSIONS l 1 Field and laboratory testing, visual classification of' rock and soil samples, and geologic reconnaissance lead to the fol-lowing preliminary conclusions:
- 1. The site is located on the western limb of a major syncline, the bedding of which dips .from the river toward the site. A major fracture pattern within the bedrock strikes 1 generally to the northwest and has a near vertical dip.
- 2. The subsurface profile at the site is made up of three basic strata, encountered as follows:
- a. A construction fill, generally consisting of ;
silt, sand and gravel or ash and cinders.
- b. A layer of boulders in a silty clay matrix,
- c. Bedrock, consisting of siltstone, sandstone and red beds.
- 3. The relative permeability of the rock and soil'are as follows:
- a. In general, the construction fill and boulder l
, layers are less permeable than the bedrock,
- b. The boulder layer appears to act as a barrier to flow of groundwater between the construction fill and bedrock.
g caotuowerte recurotoonm

- c. The permeability of the bedrock varies with depth. The highest permeability is at the boulder layer-bedrock interface. This is probably a function of the weathered nature of the top of the bedrock, which is quite fractured resulting in this higher permea-bility. Other zones of comparatively high permeability may be present in the bedrock such as has been identified at borings B-3 and B-5.
- 4. Groundwater level observations in test borings indicaLe a groundwater gradient of 10 to 15 feet over a distance of 600 to 800 feet from the site to the river.
- 5. The combination of groundwater gradient, bedrock permeability, and bedrock structure (bedding and fracture patterns) indicates that the groundwater 4 has a potential to migrate from the site toward the river.
6 Groundwater entering the pipe tunnel through the joint between the pipe tunnel and the containment shell has the potential to drain into the radwaste ' treatment plant. As the groundwater levels decrease through the hydrologic year this process can reverse, i causing water to drhin back through the joint and l out into the groundwater regime. ' RECOMMENDATIONS If the results of the recently conducted radiological tests of the soil, rock and groundwater at the Saxton site warrant the implementation of a groundwater monitoring program for the more definitive determination of the groundwater flow regime, the strategy for locating the monitoring points should consider the following recommendations:
- 1. The field and laboratory tests cuciucted on both the soils and the bedrock at the Saxton site indi-cate that the bedrock is the predominant water bearing zone and consequently more emphasis should be placed on groundwater monitoring in the bedrock.
- 2. Geological information strongly supports the premise that groundwater traveling from a deep source (e.g.
the containment, seated approximately 50 feet into the bedrock will travel generally northwest, fol-lowing the structural orientation of bedding and the major fracture set. Therefore, any future monitor-ing points addressing contamination from structures gcxuowecomm:
16 j l founded in the bedrock should favor a northwest- I southeast orientation (Figure 5).
- 3. In the absence of precise groundwater elevation in-formation at the site, it is difficult to predict the groundwater flow paths which are not directly influenced by the structural controls of the l bedrock. The flow patterns at the top of rock are '
probably affected'more by the geomorphological con- j ditions and properties of the soil zones. The site i is surrounded on three sides by surface waters which could act as discharge points'for groundwater flow (Shoups Run to the east and,Raystown Branch of the Juniata River on the west and north). Topographi- ! cally, the most likely direction of shallow ground- ) water flow from the site appears to range from the southwest to the north (Figure 6). Therefore, ; baseline piezometry should be acquired in this area. ! l e 9 e i GGOtf40wifER TECHNOLOGUJC

- of sand. Mineralogical varieties such as feldspathic and glauconitic sandstones are recognized, and also, argillaceous, siliceous, calcareous, ferruginous, and other varieties according to the nature of the binding or cementing material.
Shale - A laminated sediment in which the constituent particles are predominantly of the clay grado. Shale includes the indurated, laminated, or fissile cla'ystones and siltstones. The cleavage is that of bedding and such other secondary cleavage or fissility that is approximately parallel to bedding. The secondary cleavago has been produced by the pressure of overlying sediments and plastic flow. Sil tstone - A very fine-grai ned consolidated clastJc rock composed predominantly of particles of siit grade. Strike - The course or bearing of the outcrop of an inclined bed or structure on a level surface; the direction or bearing of a horizontal line in the plane of an inclined stratum, joint, fault, cleavage plane, or other structural plane. It is perpendicular to the direction of the di p.
