3.0 PERMEABILITY AND POROSITY In response to the request for a record of all permeability and porosity evaluations made of the unconfined aquifer and the* Blue Bluff marl (letter from E. G. Adensamto D. O. Foster, dated February 19, 1985), the following discussidn and accompanying tables are submitted.
Logs of the holes in which permeability tests were conducted or from which samples were taken for analysis of permeability and/or porosity are included with this supplement.
3.1 Permeability Host of the permeability (hydraulic conductivity) testing was done during the initial site exploration, and was reported in the PSAR.The field tests performed in exploratory holes at the intake structure were done after the PSAR was initially submitted and were reported in the FSAR.
Two pumping tests were conducted in the unconfined aquifer at the request of the consultant designing the temporary construction dewatering system.
These data had not been submitted previously in the SAR.
In response to the request for all permeability data, a thorough review of the records of investigation, 1971 to the present, was made, and the data from these tests were found.
They have now been analyzed to determine representative permeability values and are submitted with this response.
The drilled holes or wells in which tests were conducted, or from which samples were taken for laboratory analysis are shown on the attached figure.
The holes drilled for the dewatering tests were not logged by a soils engineer or geologist.
However, the drillerts logs are submitted with this supplement.
I The hydraulic conductivity of the water-table (unconfined) aquifer was measured in the field by constant-head inflow methods (including open stand-pipe and permeameter tests), constant-discharge pumping tests, and variable-head inflow methods.
In addition, laboratory permeability tests were made on samples taken from one exploratory hole (107A) and on grab samples ' of backfill material.
Estimates of hydraulic conductivity were reported for selected soil samples.based on a theoretical relationship to grain size.
Hydraulic conductivity of the marl was measured in the field in exploratory holes by constant-head inflow methods.
In all but two cases, packers were used to isolate test intervals.
Two permeameter tests were conducted in weathered marl.
No laboratory tests of marl permeability were done.
3.1.1 constant-discharge (pumping) tests.
Two test wells, each with an array of 4 observation wells, were constructed in the vicinity of the Power Block excavation to conduct aquifer pumping tests.
Locations are shown on the attached Figure 3-1.
The purpose of the tests was to provide data on the permeability of the Utley limestone, which, beneath the site, is composed predominantly of shells in a matrix of silt and clay, but includes thin and discontinuous beds of lime.stone, sands and coquina.
It was throught in the initial plans for dewatering that the formation might be very permeable and act as a drain for dewatering.
The first well, W-l, was pumped at a rate of 36 gpm for a period of 97 hours0.00112 days <br />0.0269 hours <br />1.603836e-4 weeks <br />3.69085e-5 months <br />, and response was sufficient in all four observation wells for analysis.
The second well, W-2, was in a much less permeable zone of the formation than the first well, and response in the observation wells was negligible to small and analysis was not feasible.
The average yield of W-2 was 12 gpm but it fluctuated considerably and the test was terminated after 27 hours3.125e-4 days <br />0.0075 hours <br />4.464286e-5 weeks <br />1.02735e-5 months <br />.
The two tests indicated that transmissivity of the Utley limestone is relatively low and varies considerably from place to place.
It was concluded the formation would not be an effective drain for dewatering.
In addition to the two conventional pumping tests, constant-head tests were conducted in some of the observation wells.
During two of these tests, the water-level rise in an adjacent observation well was measured.
The response of observation well 2A to the constant inflow of
72 gpm at well 2B was adequate for analysis as an inverse of a pumping test.
The other test was not sufficient for analysis.
A summary of these tests and the analyses are provided in Table 3-3.
3.1.2 Constant-head tests.
Host of the field tests were of the type wherein water is introduced into the aquifer through the exploratory hole or completed well by maintaining a constant hydraulic head (pressure) in the hole.
The rate of inflow is monitored and permeability calculated with the data collected.
Inflatable packers were used to isolate a specified test interval in the exploratory holes.
In wells, the screened interval was assumed to be the test interval.
The procedure followed is that provided by Designation 18 of the u.s. Bureau of Reclamation Earth Hanual.
The data of these tests are included on the drill_logs of the tested hole, or on accompanying sheets with -the drill logs.
The tests of unconfined sands conducted in holes 183 and 184 followed the test procedure described as Designation 19, Permeameter Test, of the U.S.B.R. Earth Manual.
The intervals tested were determined by the screened portion of casing installed in the holes.
Results of the constant-head tests are listed in Table 3-1 and 3-2.
3.1.3 Falling-head tests.
In addition to the pumping tests conducted for dewatering design, falling-head tests were conducted in the temporary observation wells constructed for those pumping tests.
A measured volume of water was introduced into the well, and then the rate of decay of the
column of water in the well was monitored.
These data were analyzed by the falling head method, as described in the u.s. Bureau of Hines Open File Report 136-77, "Field Permeability Test Methods with Application to Solution Mining", 1977.
Results of these tests are listed in Table 3-3.
3.1.4 Laboratory Tests.
As part of the initial investigations to determine the foundation soil properties, laboratory permeability measurements were made of Barnwell -sand samples taken from borehole l07A.
Three of those samples were undisturbed samples.
The fourth was a disturbed sample for which permeability was measured at three densities.
Similarly, laboratory tests were made at three densities of two "gr-ab" samples of backfill material.
The backfill samples were selected for different amounts of material finer than the No. 200 sieve: one sample with 5.9~, and one with 11~ fines.
The testing procedure followed was to saturate the samples by the back-pressure technique, confine them at the effective overburden pressure, and then maintain a constant hydraulic gradient across the sample.
Results of laboratory tests are listed in Table 3-1.
3.1.5 Grain-size analyses.
A common method of estimating permeability of sands is by applying the approximate relationship to grain size found by A. Hazen for filter sands (Freeze, R.A., Cherry, J.A., "Groundwater",
1979, Prentice-Hall Inc.):
2 K = Ad10 The d10 value is the 10~ finer grain size, and if expressed in millimeters. A is equal to 1.0. and K is expressed in em/sec.
Although
I the approximation was developed for uniformly graded sands, it has been commonly applied as a rough estimate of other sands.
The estimates are listed in Table 3-1.
3.2 Porosity The drill holes, or sites, from which the samples analyzed were taken are shown on Figure 3-1, the porosity calculations are listed in Table 3-4.
The drill logs of the holes are also submitted.
The laboratory determinations of soil properties were directed to those units on which structural units are founded.
These include the Blue Bluff marl and the upper sands of the Barnwell Group.
No records have been found of any tests conducted on samples of the Utley limestone unit.
Porosity of the Blue Bluff marl was calculated from laboratory soil analyses of undisturbed samples taken in exploratory holes during the initial site studies.
The determined porosities range from 24~ to 62~.
There were 18 samples analyzed.
The mean porosity value is 47.5~.
Porosity of undisturbed Barnwell sands and/or silty sands (some from the water-table aquifer) have also been determined.
Fifteen samples were analyzed and porosity values range from 34~ to 61~ with a mean of 43.9~.
In addition, porosity in relation to density of two recompacted samples of Barnwell sands used for backfill material is provided.
Porosity of the Utley limestone is estimated from descriptions of the material.
Descriptions of the material are available from mapping of the power-block excavation and from exploratory drill logs.
0635g
I The Utley unit was exposed at the base of the cuts in the power-block excavation, and ranged from less than one-foot, to more than twelve feet thick.
Unfortunately, extensive slumping and regrading obscured this portion of the slopes and detailed description was not possible.
The more resistant, indurated limestone units tended to remain exposed.
Jointing and/or fractures were not reported present in the indurated limestone beds.
Cavities were present in the upper, thickest limestone unit on portions of the north and west slopes.
It is estimated that cavities make up 5~ of the unit in the excavation exposure.
More representative descriptions of the Utley unit are provided by the core recovered from the many exploratory holes drill~d throughout the VEGP site.
From these descriptions, the Utley limestone beneath the site is comprised predominantly of shells in a partially cemented matrix of silt, clay and sand.
There are discontinuous beds of hard dense limestone, relatively clean sands, and coquina.
Ho joints or fractures are reported in the material apart from the cavities.
Based on these descriptions, it appears that primary (intergranular) porosity remains (pores have not been filled by cementation).
Joints and fractures (other than the cavities) contribute a negligible quantity of openings.
The Utley unit beneath the VEGP site is classified as a partially cemented silty sand.
Total porosity varies from place to place and is estimated to range from lS~ to 60~ (depending on sample size, porosity would be lOO~ where cavities are present, and less than lO~ in the dense limestone beds).
Effective porosity is estimated to be 30~.

Holes 183 and 184 were drilled by Law Engineering Co. and no geologic drill logs were made from these holes.
The depth and interval tested were based on geologic information correlated from nearby drill holes.
The nearest hole to 183 is 139 and the nearest to 184 is l07A.
The following information ;s provided in Section 2.4.13.2.1.3 of the Preliminary Safety Analysis Report.
G.
Tests in the Shallow Sands.
Pump-in tests were conducted in two borinas to provide data for determining
~'le perneability-of the nonindurated, saturated sands overlying tl1e marl *. The two borings (183 and 184) are at opposite edges of the site area for Units 1 and 2, as shown on figure 2. 5-1.
Determining t:'1e perceability of those sands assists in designing a dewatering system and also provides data for estimating the rate of ground water movement.
VNP 1.
Procedure.
The test holes were drilled similarly to those for the tests conducted in the marl.
After drilling to the desired intervals to be tested, 2-inch diameter PVC pipe with a 10-foot screened interval was placed in each hole, and the holes flushed with clean water.
It was necessary to place a screen in the test interval:
othel:Wise, the nonindurated sands would cave.
The tests were conducted by personnel of Law Engineerinq Company on November 3, 1971, in accord with the method listed under Desiqnation E-19 of reference 4.
A constant head was maintained in the well by controlling the flow of water from a calibrated tank.
The discharge passed throuqh a line extending below the water table to minimize aeration of the water.
Determination of permeability is made wi th the following formula (condition of water table above the bottom of the tested interval) :
where:
k =
525.600 loge (~) 1; h2[(%rl-1/2 (~f2]
k = coefficient of permeability, feet per year h = height of water in the well, feet r = radius of well, feet Q = discharge rate of water, cubic feet per minute S = difference in head between water in the well and the water table, feet This formula is modified from the formula given in reference 4, in not adjusting the coefficient to conditions of water viscosity at 20 C temperature.
It is assumed this adjustment is small (temperature of the water used ranged from 20 to 22 C).
The borings were NX size, so that the radius was 0.15 foot, and the difference in head was maintained at a constant 2 feet in both tests.
The calculated permeabilities were 200 feet per year at Hole 183, and 267 feet per year at hole 184.

VNP 2.
Findings.
Data collected durinq the tests are listed in table 2.4-6.
In addition to the above, the following conditions held at each hole:
