1.0 SUMMARY AND CONCLUSIONS

I .

i

b-

The recent t e s t d r i l l i n g program, which included the construction and preliminary pump tes t ing of a screened test-production well, on R.W. Por te r ' s Property on White Lake Road s o u t h of Kitley Lake, has shown the following:

1 . I n the area o f the intersect ion of White Lake Road and the Access Road t o the R.W. Porter Property, the overburden sediments are t h i n . Two t e s t holes were d r i l l e d t h r o u g h 2 .4 t o 3.0 m ( 8 t o 10 f t ) o f clay, compact gravel and t i l l . I n the f i r s t t e s t hole, a f r ac tu re zone between 4.3 and 6 .7 m (14 and 2 2 f t ) i n red-coloured bedrock yielded a b o u t 2.3 L/rnin ( 3 gpm). The second hole contained no water-bearing zone t o the t o t a l depth of 13.1 m (43 f t ) .

2 . The sediments a t the s i t e of Test Well No. 1-1991, i n the central par t of the Kitley Valley, contain a coarse sand aquifer between 3.7 and 9.1 m ( 1 2 a n d 30 f t ) i n which a screen was s e t between 6.63 and 9.39 rn ( 2 1 . 7 5 a n d 30.8 f t ) ; the aquifer i s non-flow ar tes ian w i t h a confining layer o f c lay t o 2 . 4 m ( 8 f t ) a n d a s t a t i c water level close t o surface.

3. Test Well No. 1-1991 was pump tes ted a t a constant r a t e of 9.1 L/sec (120 igpm) f o r f ive hours, a t the end of which the pumping water level was i n the screen and was s t i l l drawing down. The capacity of Test Well No. 1-1991 i s c l ea r ly much less t h a n the t e s t r a t e of 9.1 L/sec.

4. Following the termination of p u m p i n g , the water level recovered f a i r l y rapidly, showing good recharge a t the time of the t e s t on June 14 . From the recovery d a t a , a moderate aquifer t ransmissivi ty of 337 m2/day (2 .26 x 104 igpd / f t ) i s calculated. Under the prevailing hydrogeoJogic conditions, aquifer transmissivity i s not considered t o be the control l ing fac tor insofar as aquifer a n d well capacity i s concerned; ra ther , the nature of aquifer recharge a t the end of the summer drought will ult imately determine the amoun t of groundwater which can be exploited by wells.

l i

5. Assuming that there is no significant seasonal decline in the water level in Test Well No. 1-1991 and, based on projected drawdown to 100 days of continuous pumping, a theoret ica l capacity of about 3.03 L/sec (40 igpm) is calculated for Test Well No. 1-1991.

6. A chemical analysis of a water sample collected from Test Well No. 1-1991 near the end of five hours of pumping shows a moderately highly mineralized water which is fairly hard and typical of groundwater quality in the B.C. Interior. The water quality shown by the analysis is certainly acceptable for domestic use; the analysis also showed the water to be free of iron.

-- 7 . Before finalizing subdivision plans, the capacity of the aquifer in the

Kitley Valley must be better evaluated at the time of minimum groundwater conditions, to ensure that recharge conditions are satisfactory at that time.

2.0 RECOMMENDATIONS

All things considered, before proceeding with additional t e s t d r i l l i n g or other work necessary t o "prove u p " a water supply source fo r R.W. Por t e r ' s proposed Kitley Lake Subdivision, i t i s obvious t h a t the aquifer encountered in Test Well No. 1-1991 should be be t te r evaluated as a long-term water supply source. We recommend the following:

1 . During the summer, monitor the water level in the well in an e f f o r t t o determine i f there i s a seasonal decline a n d , i f so, the amount of the decline. Semi-monthly water level observations would be sui table .

2 . A t the end of the summer, when groundwater conditions are minimum, a t the time of no recharge and high evapotranspiration, carry o u t an aquifer t e s t - i n p a r t i c u l a r , t o evaluate the aquifer recharge s i tua t ion .

3 . From the r e su l t s o f 1 . and 2., decide on whether additional t e s t d r i l l i n g should be carried o u t a n d , i f so, where.

This report has been prepared to:

1. Describe the results of the test-production drilling at three sites on R.W. Porter's Property on the west side of White Lake Road south of Kitley Lake.

2 . Outline a program for completing an evaluation of the groundwater potential on R.W. Porter's Kitley Lake Property so that subdivision plans can be formulated based on the quantity of groundwater available.

~-... A "Concept Plan" for subdivision of R.W. Porter's Kitley Lake Property is given in a report by G.G. Runka Land Sense Ltd., dated September 1980, and i denti f i ed as "Overview Expl anatory Notes to accompany LAND RESOURCE MAP FOLIO". The subject Porter Property is legally described as a combination of:

Sb of N3, Sec. 10, Tp. 88, S.D.Y.D. (k135 acres/k54 hectares);

N$ of S3, Sec. 10, Tp. 88, S.D.Y.D. (k.145 acres/k59.5 hectares);

D.L. 2454s, except Plans 19670 and 20503 and Lot 1 of Plan 23864

Lot 2, Plan 23864, D.L. 2454, S.D.Y.D.

(kt-115 acres/k46.5 hectares);

Meetings in Penticton on March 25, 1991, at Century 21's Office, and later onsite at the Property, were held to discuss subdivision possibilities and groundwater exploration. Present at the office meeting were: Mr. Bob Porter, Property Owner; Mr. Bob Little, representative for the Owner; Mr. Len Fox, P. Eng., now of REMAX Penticton Realty; Mr. Keith Robbins of Robbins Water Well Drilling Ltd.; and Mr. Ed Livingston, P. Eng., of Pacific Hydrology Consultants Ltd. Except for Mr. Fox, all present at the office meeting subsequently were present at discussions in the field where three sites for test-production drilling were selected: two sites in the area of the intersection of the Property Access Road and White Lake Road, where there are presently two dug wells, and the third site in the Kitley Valley on the road which crosses the waterlogged area.

4.0 TEST-PRODUCTION DRILLING AND WELL CONSTRUCTION

4.1 General

, "

L

The test-producti on dri 11 i ng program was car r ied o u t by Robbi ns Water Well Dri l l ing L t d . u s i n g a cable tool d r i l l rig and 150 mrn (6") diameter casing. As i t turned out , the t e s t hole a t the t h i r d s i t e i n Kitley Valley was completed as a screened Test Well (No. 1-1991) . The approximate locations of the two Test Holes and the Test Well are shown on Figure 1 i n Appendix A . The d r i l l e r ' s l i thologs and other de t a i l s about the two Test Holes and the Test Well are contained i n Appendix B.

4.2 Test Holes No. 1-1991 and No. 2-1991

The f i r s t t e s t hole (No. 1-1991) was d r i l l e d a short distance s o u t h of the intersect ion of the Property Access Road w i t h White Lake Road. I t was d r i l l e d t h r o u g h 1 . 5 m ( 5 f t ) of so f t sandy clay over 1 .5 m ( 5 f t ) of compact sand and gravel where i t reached varicoloured volcanics of the Kitley Lake Member of the Marron Formation of ear ly Tert iary Age, which underlie the subject area. A t Mr. L i t t l e ' s ins t ruc t ion , d r i l l i n g was continued t o a depth of 20.4 m (67 f t ) i n the rock. A small f rac ture zone i n the interval 4.3 t o 6 . 7 m ( 1 4 t o 22 f t ) yielded a small amount of water, which was shown by bail t es t ing t o be a b o u t 2.3 L / m i n ( 3 gpm) . A t o p was welded on the 150 mm ( 6 " ) diameter casing, which was in s t a l l ed t h r o u g h the overburden t o a depth of 3.35 m ( 1 1 f t ) .

The second Test Hole (No. 2-1991) was d r i l l e d i n the same general area, on the south s ide of the Property Access Road i n d c lose t o White Lake Road, a t a s i t e between the two ponds. Test Hole No. .2-1991 encountered 2 .4 rn ( 8 f t ) of compact sediment over bedrock. A t t h i s s i t e , the casing was recovered.

U

4.3 T e s t Well No. 1-1991

The t e s t hole a t the th i rd s i t e i n the Kitley Valley encountered a sand and gravel aquifer between 2.4 and 9.1 rn ( 8 and 30 f t ) , overlain by clay and underlain by 0.9 m ( 3 f t ) of compact sediment, described by the d r i l l e r as " t i l l " , above so f t red bedrock.

Samples of aquifer sand and gravel i n the interval 4.3 t o 9.1 rn ( 1 4 t o 30 f t ) were shipped t o Pacific Hydrology and sieve analyses were carr ied out t o design a screen; the sieve analyses p lo ts a re included i n Appendix B. Based on these analyses, 2 . 4 rn ( 8 f t ) of 150 mm ( 6 " ) nominal diameter Johnson s t a in l e s s s tee l well screen, consisting of 1 . 2 rn ( 4 f t ) of 2.54 mm (0.100") s l o t over 1 . 2 m of 3.05 mm (0.120") s l o t was i n s t a l l ed between 6.63 and 9.39 m (21 .75 and 30.8 f t ) . Details of the construction o f Test Well No. 1-1991 are shown on Figure 2 in Appendix B (Page B - 4 ) .

Development o f Test Well No. 1-1991 was carr ied o u t by standard we1 1 development techniques of bai 1 i n g , surging and pumping, u n t i 1 the amount of sand t h a t could be brought in to the well was reduced t o an

'acceptable level .

5.0 PUMP TESTING

5.1 Test Procedure

i Following completion of the well development, Robbins Water Well

Dri l l ing L t d . carr ied out a constant-rate pumping t e s t fo r 300 minutes ( f i v e hours) a t a r a t e of 9.1 L/sec (120 igpm). Following the termination of pumping , the recovery of the water level was observed fo r 30 minutes.

5.2 Test Results

Data collected d u r i n g the pumping t e s t are included i n Appendix C , along w i t h s t a n d a r d s t r a igh t l i ne plots of the data on semi-logars-hmic g r a p h paper.

The plot of the drawdown d a t a (Figure 3, Page C - 4 ) shows t h a t :

1 . More t h a n half of the drawdown which occurred d u r i n g the 300 minutes of pumping took place in the f i r s t minute of pumping. However, since the residual drawdown i n the f i r s t minute a f t e r pumping stopped was only 1.00 m (3 .29 f t ) , compared t o 4 .78 m (15.67 f t ) i n the f i r s t minute of p u m p i n g , i t seems l ike ly t h a t an aquifer boundary was intercepted almost immediately a f t e r p u m p i n g s t a r t ed .

2 . A negative aquifer boundary was de f in i t e ly intercepted a t about 90 minutes a f t e r the s t a r t of p u m p i n g ; t h i s boundary i s ref lected i n a steepening of the drawdown p l o t .

The plot of the recovery o f the water level following the termination of pumping (Figure 4 , Page C - 5) sh6ws t h a t recharge conditions were cer ta in ly good a t the time of the t e s t on June 1 4 , a s ref lected i n rapid recovery of the water level t o the pre-pumping s t a t i c level . From the recovery p lo t , an aquifer t ransmissivi ty of 337 m2/day (2 .26 x lo4 igpd / f t ) i s calculated. This i s a moderate t ransmissivi ty showing good water-yielding capabi l i ty f o r the aquifer. However, under the prevail ing geologic conditions, the aquifer transmissivity i s n o t the constr ic t ion t o well capacity; ra ther the nature of recharge a t the end of the summer d r o u g h t w i l l be the main f ac to r determining well capacity.

7.0 GROUNDWATER QUALITY

A water sample was col lected near the end of the pumping t e s t and submitted t o Analytical Service Laboratories L t d . (ASL) for analysis. The report from ASL i s contained i n Appendix D.

The ASL analysis shows a groundwater typical of the B.C. In te r ior . The water i s hard and moderately highly mineralized. I t i s a calcium + magnesium/bicarbonate type water. The groundwater represented by the ASL analysis meets guidelines of B.C. Ministry of Health and Health and Welfare Canada fo r a l l parameters checked. The groundwater i s generally of good qua l i ty f o r domestic uses.

The laboratory conductivity, a general measure o f the mineralization of a water o f 443 microsiemens, i s i n c lose agreement w i t h the conductivity of 400 microsiemens of the outflow of Kitley Lake, measured w i t h a f i e l d meter conductivity a t the time o f the f i e l d investigation of March 25, 1991.

8.0 COURSE OF ACTION

f 'I

Under the prevailing circumstances, i t i s obvious t h a t careful pump t e s t ing of Test Well No. 1-1991 m u s t be carr ied o u t a t the end of the d r o u g h t period t o provide a r e a l i s t i c basis for evaluating the capacity of the aquifer in the Kitley Lake Valley. Depending on the outcome of such t e s t i n g , i t may also be advisable t o continue the groundwater exploration program. If the aquifer which y ie lds water t o Test Well No. 1-1991 i s a local isolated p a t c h and n o t par t of a continuous aquifer f i l l i n g the Valley, i t may be possible t o construct other s imilar wells in other patches o f aquifer . On the other h a n d , i f there i s one continuous aquifer f i l l i n g the valley t o Kitley Lake, which receives only limited recharge, additional wells may n o t y ie ld more water.

As mentioned previously, the amount o f seasonal f luctuat ion in the water t a b l e w i l l give some clues a s t o the scale of groundwater f l o w system and thus t o the nature o f recharge. This knowledge, combined with a careful p u m p i n g t e s t of l e s t Well No. 1-1991 a t the end of the summer d r o u g h t , will e i t he r provide a basis for establishing the groundwater potential on R.W. Po r t e r ' s Kitley Lake Property or for defining w h a t i s necessary t o be t te r evaluate the groundwater potent ia l .

All things considered, the following course o f action i s recommended:

1 .

2.

3.

Monitor the water level in l e s t Well No. 1-1991 on a semi-monthly basis throughout the summer.

A t the end of the summer d r o u g h t , ca r ry o u t a long-duration pumping t e s t o f l e s t Well No. 1-1991, ensuring t h a t the discharge water from the t e s t i s conveyed o u t of the Kitley Lake basin by direct ing i t over the ridge t o the eas t .

A t the end of the long-duration pumping t e s t , co l l ec t a water sample and obtain a par t ia l analysis t o determine whether there are s ign i f icant seasonal changes in groundwater q u a l i t y .
