INTRODUCTION
The Merritt area was recommended by M. Wei (1986) f o r establishment of a
well f o r the Groundwater Observation Well Network Program to monitor
regional groundwater conditions i n the Nicol a-Col dwater Val ley. The c i t y of
Merritt i s located e a s t of the confluence of the Nicola River and Coldwater
River (Figure 1). Merritt i s underlain by a shallow fluvial sand and gravel
aquifer. Four h i g h capacity wells located w i t h i n the aquifer supply water
t o approximately 6000 residents.
Currently the consumption of the City of Merritt wells varies from a low of
1.5 mill ion gallons per day i n the winter months to a high of 5.5 mill ion
gallons per day i n the summer according to City of Merritt s t a f f .
Establishing a groundwater observation well i n this area will enable
long-term monitoring of water levels and water quali ty of the underlying
surfici a1 aqui fer. Water qual i t y monitoring is an important.. concern of
areas w i t h shallow surf ic ia l unconfined aquifers a s these aquifers are more
susceptible to groundwater contamination.
In September 1986 a f ie ld survey was conducted i n an attempt to locate an
abandoned well f o r use as an observation well. T h i s attempt, however, was
unsuccessful and i t was decided t o d r i l l an observation well. In November
1986, a d r i l l s i t e was selected by D. Kalyn i n conjunction w i t h the City of
Merritt s t a f f . The s i te is located on Crown Land along Coldwater Avenue

(F igu res 2 and 3 ) and i s c u r r e n t l y used as a recrea t ion l o t by the Minis t ry
o f Fores t s and Lands. An agreement w i t h B.C. Building Corporat ion was
obtained i n o rder to allow the d r i l l i n g of an observat ion well on this l o t
and t o allow monitoring of the well f o r a m i n i m u m 10 year period.
WELL CONSTRUCTION
D r i l l i n g and t e s t i n g was c a r r i e d out by M. Schib l i Water Wells of Lumby,
British Columbia, under Government Contract No. 84. Construct ion of the
well took place on March 2 t o 5 , 1987, and t o t a l c o n t r a c t c o s t s were
$4,462.82. These c o s t s a r e itemized and shown i n Appendix A. The 152mm
diameter well was d r i l l e d by the a i r ro ta ry method t o a depth of 17 metres
Well cons t ruc t ion d e t a i l s a r e i l l u s t r a t e d i n Figure 4. Due to boulders near
ground level, no s u r f a c e casing was i n s t a l l e d i n this well. D r i l l i n g

developed for 3 hours using compressed a i r w i t h the water conta in ing much
sand a t the start and clearing up considerably near the end of development.
Sieve analyses were performed from 3 separate samples taken a t depths
between 11.0 metres and 14.9 metres (Appendix A ) . Results of the sieve
analysis indicate t h a t a 50-slot screen would theoret ical ly retain 60
percent of the material. T h i s screen selection may be conservative for
production purposes, however, i t i s satisfactory for the wells intended use
of water level monitoring.
WELL TESTING
On March 4 , 1987, a constant ra te pumping t e s t was conducted us ing a
Berkeley 5 horse power submersible pump. The pump was s e t a t 11.7 metres
and the well was pumped for 6 hours a t a ra te o f 4.95 l i tres/second (78.5
USgpm). An o r i f i ce was se t up a t the end of the discharge l i ne
approximately 140 metres from the well i n order to measure the rate of
discharge. The i n i t i a l s t a t i c water level was 4.390 metres below the t o p of
the 152mm diameter casing and water levels stabil ized almost immediately
a f t e r pumping began (Appendix B ) . After 6 hours of pumping, the final water
level reading was 5.070 metres representing a drawdown of 0.680 metres or 8
percent of the total available drawdown to the t o p of the well screen.
Recovery was rap id w i t h the water level recovering t o w i t h i n 0.011 metres o f
the original s t a t i c water level only 4 minutes a f t e r pumping had stopped.
From the pumping t e s t resu l t s , a f t e r 360 minutes of pumping a specific

Ryznar S tab i l i ty Index value of greater than 7 i s said to be corrosive while
a value of l ess t h a n 7 i s considered to be incrustive. Using f i e l d and
laboratory resu l t s , an RSI value of 9.44 was calculated indicating the
groundwater has a potential to corrode. I t should be mentioned tha t this
well has been sampled i n l a t e 1987 for PCP contamination due to suspected
contamination from local mil 1 s using wood-preservatives. One sample taken
December 14, 1987 showed 25)~g/L PCP (Pentachlorophenol ) , (Wei, M. 1988).
HYDROGEOLOGY
A t present Groundwater Section has 2 1 well records i n Merritt. Some of the
wells were unsuccessful testholes and have been abandoned. Most of the
wells are l e s s than 100 f e e t deep and are completed i n t o a shallow gravel
and sand deposit which forms the principal aquifer i n the region. The
aquifer i s unconfined and is generally between 20 f e e t and 50 f e e t thick and
supplies several hundreds of gallons per minute to wells. The City of - -- -- .-
Merrit t and Co l l e t tv i l l e Improvement D i s t r i c t production wells are completed
i n the same deposit b u t i n a deeper gravel-fi l led channel. These production
wells have a capacity of about 1000 gpm to 1500gpm. T h i s channel, located
a t the northwest end of town i s apparently very narrow, up to a depth of 100
f e e t or more and may extend i n an east-northeast direction. Observation
Well No. 296 i s completed i n the aquifer b u t d id not encounter this channel
of coarse grained sediments by the Nicola and Coldwater Rivers.

The aquifer transmissivity, ranges between 5x104 and 10x104 gpd/ft , typical
of moderately transmi ssive aquifers. Regional fl ow appears to be downs1 ope
towards the west. Recharge to the aquifer may come from r ive r flow and
d i r e c t precipitation. The f ac t tha t the aquifer is permeable, unconfined
and located a t a shallow depth makes i t susceptible to pollution, regular
sampling of Observation Well No. 296 t o monitor water quali ty is recommended
and shou ld a lso include the tes t ing fo r PC contamination. q? The aquifer i s underlain by f i n d sand, s i l t and clay. T h i s depos i t outcrops
on the h i l l s ide beside the aquifer and forms an aquitard of about 200 feet
t o 250 f e e t thickness below the valley floor. The s i l t and clay deposit was
formed by depos i t ion of fine-gained sediments i n a prehistoric glacial lake
covering Merritt. The River Ranch wells just northeast of the c i t y are
completed i n t o sand and gravel layers i n or beneath this deposit. These
sand and gravel layers form flowing ar tes ian aquifers which reportedly
supply up t o 7000 gpm to wells b u t which are not well defined i n location.
Alluvial and glaciofluvial deposits associated w i t h the glaciolacustrine
deposit occur southeast and northwest of Merritt respectively (Figures 5 and
6 ) . Groundwater potential i n these depos i t s is unknown.
01 der unconsolidated deposits may l i e beneath the glaciolacustrine depos i t
and above bedrock. Presence of these unconsolidated deposits are inferred
from d r i l l log data only. Groundwater development i n these deeper deposits
have not been explored as most of the exploration, development and
exploitation of the groundwater resource has taken place i n the shallow,
- 8 -
productive sand and gravel aquifer i n which Observation well No. 296 i s
compl eted.
CONCLUSIONS AND RECOMMENDATIONS
1 1 1 1 I I 1 I I I I I I I I ,I
One 152mm diameter observation well was dr i l led for the Ministry of
Environment w i t h a t o t a l contract cost of $4462.82. The surf ic ia l
well was completed w i t h i n a unconfined aquifer t o a depth of 14.3
metres.
A1 1 water chemistry parameters tested are w i t h i n the maximum
acceptable concentration set o u t i n "Guide1 ines for Canadian Dr inking
Water Qual i t y 1978".
The observation well shou ld be sampled for complete water chemistry
analysis a t l ea s t once per year, and shou ld include tes t ing fo r PCP
contamination. The sampling shou ld be carried out i n l a t e summer - early Fa l l when groundwater levels are a t o r near their lowest.
The water level recorder ins ta l la t ion shou ld remain i n place for a
m i n i m u m period of 10 years. Water level and water qua l i t y data should
be reviewed periodically to monitor the groundwater conditions of the
aquifer.

Re: Establishment of Observation Well No. 296 - Merrit t , B.C.
Introduction
On March 5 , 1987, a Stevens water level recorder was installeG on the recently dr i l led observation well i n Merritt. T h i s well was dr i l led under government Contract No. 84 - "Drilling, Construction and Testing of One Groundwater Observation Well i n Merritt, B.C." The well i s located along Coldwater Avenue on Lot 3, Block 29, P l a n 570, KDYD ( see Figures 1 and 2 ) . T h i s property i s owned by the Crown and permission to d r i l l was granted by the British Columbia B u i l d i n g s Corporation.
The purpose of establishing this observation well i s t o monitor groundwater conditions i n the Merritt aquifer. The City of Merr i t t ' s residents rely exclusively upon groundwater for the i r domestic water supply. The potential e x i s t s f o r the City of Merr i t t ' s population to increase w i t h the new Coquihalla Highway now open and Merritt being on a major transportation route.
