The study outlines the initial process of developing a Groundwater Protection Plan for the Village of Olalla. Olalla obtains its water supply from one water well; currently there is no treatment of this water well. This report presents the basic components of steps 1 and 2 of the Well Protection Toolkit with emphasis on aquifer and wellhead characterization. Includes maps showing 60 day, 1, 5 and 10 year capture zones; catchment areas contributing recharge. RDOS, 20 pp., NTS Map 082E05

Golder Associates Ltd. (Golder) has completed the initial phase of Groundwater Protection Planning (GWPP) for the Village of Olalla (Olalla). The work was completed under the direction of the Regional District of Okanagan Similkameen (RDOS). The aquifer in Olalla is located along the valley of Keremeos Creek and has not yet been characterized by the BC Ministry of Water, Land and Air Protection (MWLAP) under their province-wide Aquifer Classification Program. However, based on the review of well logs available for the area, the aquifer is considered to be an unconfined aquifer for the purposed of this GWPP. RDOS is the owner/ operator of the municipal water distribution system in Olalla and is the primary water purveyor extracting groundwater from the aquifer within Olalla. They supply water for domestic use. This first stage of this GWPP was generally limited to the characterization of the aquifer and determination of the approximate capture zones for the single community well which comprises the RDOS system. The assessment was based on the review of information from reports available for the area, climatic data, and a windshield survey through the Study Area. The overall GWPP process generally follows the well protection toolkit (WPT) process developed by MWLAP. The scope of work for this initial phase of the GWPP consisted of the following: 1) Assist with the establishment of a Groundwater Protection Planning Committee (GPPC) with representation from the users of the aquifer, community members, government representation and technical experts; 2) Assist the planning committee with the establishment of goals, determining information needs and the development of an action plan; 3) Gather and review available information on the aquifer, prepare maps of the extent and sections through the aquifer to identify physical properties including aquifer thickness and flow direction; 4) Identify data gaps and complete a field reconnaissance to collect additional information; 5) Identify aquifer recharge and discharge areas, as well as an overall aquifer water balance, based on the established physical properties; 6) Estimate with analytical methods, the extent of well head capture zones for the large capacity water wells using the Calculated Fixed Radius (CFR) method; and 7) Report preparation. Issues related to the ability of the local aquifers to sustain the current and future water supply requirements of the District and water quality were not addressed in this study.
