1 .O INTRODUCTION

Kala Groundwater Consulting Ltd. (Kala) was retained by Mr. Ron Watt, of Armstrong, BC, to investigate and report on the groundwater potential for a proposed subdivision in the Hullcar area of Armstrong, BC. This report concerns the Phase 1 - Groundwater Potential Evaluation Program conducted by Kala in May, 1997. This project was authorized by Mr. Ron Watt, on April 2 1, 1997.

Sections 1.0 to 2.0 provide background information, sections 3.0 to 6.0 provide review findings and Section 7.0 provides conclusions and recommendations. Site location and interpretation diagrams are detailed in Appendix A, and analytical chemistry results are included in Appendix B.

2.0 BACKGROUND

The study area may be spatially described as 50’ 3 1’ North, 119’ 15’ West at a mean elevation of 500m ASL. The legal description of the property is Lot A, Plan KAP48214 and Part of Lot 2, Plan 5283, Sec 26, TP 34, KDYD, Except Plans 34479 and KAP48214, (herein referred to as the site). The site 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.

Mr. Watt proposes to subdivide the property into two residential lots. Lot sizes will be in the order of 2.lha. The overall development area is approximately 4.2 ha. The client desires to demonstrate sufficient potable water for each of the proposed lots.

2.1 Scope of Services

Potential groundwater resources are not amenable to direct observation. Kala applies conventional hydrogeologic practices to provide a professional opinion as to the presence or absence of groundwater resources within a specific area based on a thorough review of site conditions. The purpose of this GPE program was to determine the occurrence and distribution of groundwater resources within 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 6,550 L/day for each of the lots.

The site assessment consisted of the collection, synthesis, and analysis of available information. The following documents were reviewed:

Review of pertinent geological, topographical, and groundwater maps; Review of pertinent terrain, topographic, and soils maps; Review of climatological information; Review of existing aerial photographs;

0 Review of any existing reports and water well records from the BC Ministry of Environment, (MoE); Review of Ministry of Health records regarding local groundwater and surface water quality. 0

It should be noted that water well records are submitted voluntarily to the MoE, and as such some local records may be absent. Fieldwork consisted of one site visit. Kala personnel visited the site on April 16, 1997, to assess existing site conditions.

3.0 PHYSIOGRAPHY

The site is located within a broad northeast-tending valley in the Shuswap Highlands, an area of moderate relief, in the order of 300m. The site is moderately to gently sloping comprising both cleared and wooded areas. The valley floor is utilized chiefly for agricultural applications. An area of groundwater seepage was noted approximately in the centre of the property. The closest perennial stream to the site is Lyster Creek, located approximately 2 km west. Parkinson Lake is located approximately 1.0 km south. A site location and general topography map is shown in figure 1.

The physiography of the area is the product of archaean geological events that were significantly modified during the Pleistocene. The area was subjected to several glacial movements during the Pleistocene resulting in massive glacial erosions and subsequent deposition of glacial, glacio- fluvial, and glacio-lacustrine sediments.

4.0 CLIMATE

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 D b (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 m d y e a r based on 21 year norms. Table 1 provides a summary of prevalent annual climatic information:

Reference: Canadian Climate Normals Atmospheric Environment Services, Env. Can. 198 1 n = not available

Environment Canada - Summerland Research Station - indicates an annual estimated evapotranspiration rate in the order of 280mdyear for the Armstrong area. If 70% of this value occurs between June-September each year that would be the equivalent of approximately 1 .8mdday of evapotranspiration loss 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 materials, overlying a shallow, topography-controlling bedrock surface. The northeast-tending valley was likely a meltwater channel during the last glaciation. To the north of the site the hillsides 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 and drift cover appeared to be greater than 30m thick. A surficial geology map is detailed in figure 3, Appendix A.

6.0 HYDROGEOLOGY

The following discussion regarding the occurrence and distribution of groundwater within and surrounding 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. During Kala field reconnaissance, efforts were made to locate and assess other outstanding water wells.

Eleven reported water wells are completed within a 1 km radius of the proposed development area. Of the eleven wells, five are completed within fractured volcanic bedrock at depths of up to 15 1 m below surface. Bedrock yields are reported to be in the range of 0.1-3.6 L/s. Six wells are completed within unconsolidated drift at up to 43m below surface. Drift completed wells have reported yields in the range of 0.1-1.4 L/s. Table 2 summarizes the eleven local water \vel1 logs reviewed by Kala:

Table 2 - Existing Water Wells

UNC = Unconfined BED = Bedrock

It is reported that a number of local wells have been completed recently and have not yet been recorded on the BCGS systems. Reference numbers pertain to Ministry of Environment well (tag) numbers. The groundwater review indicates low to moderate yielding wells from both drift-completed and bedrock-completed wells.

In addition to the above information Kala contacted representatives of the water well drilling firms outlined in section 7.1 to discuss past experience in the project area. Each of the drillers contacted reported generally favorable conditions throughout the area with groundwater usually intercepted within 65m of surface. Local water chemistry is anticipated to be hard with elevated TDS and mineralization, based on a review of Ministry of Health records.

The wells are each reported to be capable of yields in excess of 0.06 L/s or (6550 L/day). The residents report that the groundwater quality is generally adequate with moderate hardness and mineralization.

Kala installed a bedrock-completed water well located to the southwest of the subject property within the central valley area. The well was undertaken on behalf of the Spallumcheen First Nation. The water quality appears similar to that reported local to the Todd Road area with elevated hardness and mineralization. The groundwater is amenable to water treatment using conventional ion exchange softeners with iron out filters if desired. This type of groundwater is typical to the Spallumcheen Valley and upland areas. A copy of the water chemistry data is included in Appendix B.

7.0 CONCLUSIONS AND RECOMMENDATIONS

A limited evaluation of available geological, 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.

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

0 The subject property is located north of Hullcar Road, in the Hullcar area west of Armstrong BC. The client desires to undertake the subdivision of the property into two residential lots; 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 surficial geology of the site comprises deposits of morainal till sheets which appear to control the northern and central portions of the site;

It is the opinion of Kala that individual water wells yielding in the range of 0.1-0.2 L/sec. may be completed within 80m of surface for each of the two lots. This yield would be attained via screened water wells completed within local unconsolidated deposits such as interstitial strata within the till sheet, shallow wells within the isolated surface sands or fractured deeper bedrock wells; At a pumping yield of no greater than 0.1 L/sec. (8,640 L/day), it is the opinion of Kala that drawdown interference will not be a concern provided a minimum separation distance between wells of 75m is observed; The pumping of water wells within the subject property will not detrimentally impact existing surrounding wells; Kala recommends water chemistry samples be collected for potable analysis.

8.0 CLOSURE

The GPE prepared under this cover is for the expressed use of Mr. Ron Watt and agents. This report is valid only in it’s entirety. No individual part or portion of the report may be used without the written consent of Kala. A GPE is an expression of professional opinion based on conventional hydrogeological practices. Other groundwater bearing formations may exist on the subject property and every effort has been made to review pertinent materials. Kala can not implicitly or explicitly warranty or guarantee the presence or absence of groundwater within the study area.

Kala appreciates the opportunity to assist you with this project. If there are any questions or concerns, please contact the undersigned in Kamloops at your convenience.
