Re: GROUNDWATER POTENTIAL EVALUATION LOT 1, SEC 12, TP 18, R10, W6M, KDYD, PLAN 53655 HULLCAR AREA - ARMSTRONG, BRITISH COLUMBIA

1.0 INTRODUCTION

Kala Groundwater Consulting Ltd. (Kala) was retained by Mr. Hany Morgan of Armstrong, BC to investigate and report on the groundwater potential for a proposed subdlvision in the Hullcar area of Armstrong, BC. Tnrs report concerns the Phase 1 - Groundwater Potential Evaluation Program conducted by Kala between July and August 1996. Th~s project was authorized by Mr. Harry Morgan. on July 19, 1996.

Sections 1.0 to 2.0 provides background mformation, Section 3.0 to 7.0 provides review findmgs, and Section 8 .O provides conclusions and recommendations. Site location, and interpretation diagrams are shown with Appendx A.

2.0 BACKGROUND

Mr. Morgan proposes a residential subdlvision comprising approximately 7 large residential lots. Lot sizes will be in the order of 2 ha. The overall development area is approximately 18.2 ha. in size. The client desires to demonstrate sufficient potable water for each of the proposed 7 lots.

The study area may be spatially described as 50'31' North, 119'1.5' West at a mean elevation of 5 18m ASL. The legal description of the property is LOT 1, SEC 12, TP 18, R10, W6M, KDYD, PLAN 53655, (herein referred to as the site). The subject property is located north of Hullcar Road in the Salmon Valley area west of Armstrong BC. Access is gained from Hullcar Road west of the Deep Creek intersection.

2.1 Scope of Services

The site assessment consisted of the collection, synthesis, and analysis of available information. Information and materials included hydrogeological reports; geological reports and maps, terrain, topographc and soils maps; aerial photographs; climatological dormation and water well records on file with the Ministry of Environment. It should be noted that water well records are submitted voluntarily to the Ministry of Environment Lands and Parks (MOE) and as such some local records may be absent. Fieldwork consisted of one site visit. Kala personnel visited the site on July 30, 1996 to assess existing site condltions. In general the terms of reference for this review included:

2.2 Method of Investigation

Potential groundwater resources are not amenable to dlrect observation. Kala applies conventional hydrogeologic practices to provide a professional opinion as to the presence or absence of groundwater resources withm a specific area based on a thorough review of existing site condltions The purpose of this GPE program was to determine the occurrence and dstribution of groundwater resources w i h and adjacent to the subject property. Groundwater resources at the site were investigated for the purpose of possibly developing a surface water source with a safe sustainable yield of approximately 2,270 L/day for each lot niilthm the 7 lot proposed subdlvision. A site reconnaissance visit was undertaken and the following documents were reviewed:

Review of pertinent geological, topographcal, and groundwater maps; Review of existing aerial photographs; Review of any existing reports and water well records from the BC Ministry of Environment; Review of Ministry of Health records regarding local groundwater and surface water quality.

3.0 PHYSIOGRAPHY

The site is located withm the Shuswap Highlands an area of moderate relief. The site is located with a broad northeast tending valley. Local relief is in the order of 3OOm The valley floor is utilized chiefly for agricultural applications. The site is moderately to gently sloping comprising both cleared and wooded areas. The area was subjected to several glacial movements during the Pleistocene resulting in massive glacial erosions and the subsequent deposition of glacial, glacio-fluvial and glaciolacustrine sediments. The physiography of the area is the product of archaean geological events that were significantly modified during the Pleistocene. The closest perennial stream to the site is Lyster Creek located approximately 2 km. west. A site location and general topography map is shown in figure 1.

Altitude and physiography determine local climate. The climate of the Hullcar area is designated as a transition between Koppen's BSK (middle latitude steppe climate) and the cooler Dfb (humid, continental climate). The region is characterized by frozen ground and snow cover of several months duration. Average temperature of the coldest months is below O°C and the average temperature of the warmest month is under 2OoC. Precipitation averages approximately 544 d y e a r based on 21 year norms. Table 1 provides a summary prevalent annual climatic mformation:

Environment Canada - Summerland Research Station - indicates an annual estimated evapotranspiration rate in the order of 2 8 0 d y e a r for the Sorrento area. If 70% of th s value occur between June-September each year that would be the equivalent of approximately 1 .Smm/day of evapotranspiration losses from the property area.

5.0 GEOLOGY

The surficial geology of the site comprises terraced sands and gravels of glacio-fluvial origin, and ice contact kettle and kame s e h e n t s materials overlying a shallow topography controlling bedrock surface. The northeast tending valley was a meltwater channel during the last glaciation. To the immediate north of the site the hdlsides are composed of shallow glacial tills overlaying bedrock.

The underlying bedrock is composed of andesite and agglomerate of the Tsalkom Formation (Mount Ida Group). Bedrock was not exposed locally, dnft cover appeared to be greater than 30m thick (refer to Appendix C).

The following discussion regarding the occurrence and distribution of groundwater within and surroundmg the study area is based on an assessment of prevailing geological conditions and an evaluation of water- well records on file with the Ministry of Environment. As the submission of water well logs is strictly on a voluntary basis all local well logs are not submitted. DuMg Kala field reconnaissance, efforts were made to locate and assess other outstandmg water wells.

1 1 reported water wells are completed withm 800m ra&us of the proposed development area. Of the 11 wells five are completed within fractured volcanic bedrock at depths of up to 151m below surface. Bedrock yields are reported to be in the range of 0.1-2.0 L/s. Six wells are completed within unconsolidated drift at up to 43m below sudace. Drift completed wells have reported yields in the range of 0.1-1.4 L/s. Table 2 summarizes the five local water well logs reviewed by Kala:

It is reported that a number of newer local Lvelis hate been completed which are not yet on the BCGS systems. Reference numbers pertain to Ministry of Environment well (tag) numbers. Based on Table 2 findings groundwater reserves tvithin the surrounding morainal tills, terrace sand & gravel deposits and fractured bedrock appear low to moderate. The groundwater review indlcates low to moderate yielding wells from both dnft completed and bedrock completed wells.

In addition to the above information Kala contacted representatives of the water well dnlling firms outlined in section 8.0 to discuss past experience in the project area. Each of the drillers contacted reported generally favorable condltions throughout the area with groundwater uscally intercepted within 65m of surface. Local water chemistry is anticipated to be hard with e!evated TDS and mineralization, based on a review of Ministry of Health records.

7.0 PROGRAM FINDINGS

A limited evaluation of available geological and, surface and groundwater information pertinent to the study area suggests the presence of a water bearing formation beneath the subject property within 60m of the surface.

8.0 CONCLUSIONS

Based on the Kala site review conducted in accordance with generally accepted hydrogeologic practices and the scope of services outlines in Section 2.0, Kala provides the following conclusions are submitted for client consideration:

The subject property is located north Hullcar Road in the Hullcar area west of Armstrong BC. The client desires to undertake the construction of a 7 lot residential subdivision; No perennial streams traverse the property; The climate of the assessment area is designated as a transition between Koppen's BSK (middle latitude steppe climate) and the cooler Dfb (humid, continental climate); The suficial geology of the site comprises deposits of morainal till sheets whch appear to control the northern and central portions of the site. The north portion of the site comprises steeper bedrock slopes; Based on the Kala review of prevalent geologic concfitions across the site it is the opinion of Kala that indwidual water wells y-ieldmg in the range of 0.2-0.4 L/sec. may be completed within 60m of surface across most of the lots. Th~s yield will be attained via screened water wells completed within local unconsolidated deposits such as interstitial strata withm the till sheet, shallow wells w i h the isolated surface sands or fractured deeper bedrock wells; Wells completed withm either fractural bedrock or unconsolidated drift will in all likelyhood yeld
