The process of developing a Groundwater Protection Plan was initiated for the Town of Oliver. The first three steps of the Well Protection Toolkit are utilized to review existing data and reports. Using the calculated fixed radius method the time of travel zones was delineated for each well for 60-days. A regional contaminant inventory was also completed. Includes an aquifer and water well location map and municipal water well logs. True Consulting Group, 38 pp., NTS Map 082E04

Golder Associates Ltd. is pleased to present the results of our investigation, which was conducted in order to initiate the process of developing a Groundwater Protection Plan for the Town of Oliver. The GWPP is being developed to allow for the protection of groundwater quality and sources. With the development for the GWPP, the Town of Oliver has complied with the requirements of the Interior Health Authority. Golder has undertaken the first three steps as outlined in the Well Protection Toolkit developed by the Groundwater management Section of the BC Ministry of water, Land and Air Protection, namely, Step #1 - forming a community planning team, and Step #2 - defining preliminary well protection areas and Step #3 - identify potential contaminants. Given the dependence of the Town of Oliver on groundwater as a source of water supply, and the risk of groundwater contamination from pressures related to agriculture land use and other sources, the implementation of a Groundwater protection Plan is important. This report presents the results of the following activities: 1) Review of existing data and reports; 2) Regional and time of travel zone contaminant inventories. The Study Area considered for the preliminary steps in the development of the GWPP included the Town of Oliver and areas immediately surrounding the Town. The Town is located in the southern Interior of British Columbia, within the Okanagan Valley, approximately 20 kilometres north of the Canada/ U.S. border. Currently, the Town's main source of municipal water is groundwater supplied from eleven water wells, nine of which are currently in use. The rural area of Oliver is supplied from surface water during the irrigation season and groundwater at other times. The Town's eleven wells are located within the limits of the Town, and areas to the north and south of the Town. The wells supply water to both the Town of Oliver and outlying areas located within the Regional District of Okanagan Similkameen. In addition to the existing eleven municipal water wells, Golder has recently monitored the drilling of additional water well in the Blacksage area. This brings the total number of municipal water supply wells for the Town of Oliver to twelve. Preliminary time of travel zones were estimated using the calculated fixed radius ("CFR") method. The CFR method of analysis depicts time of travel zone as being circular, and tends to overestimate areas with relatively flat hydraulic gradients, and underestimate areas with steeper gradients. The results for the 60-day time-of-travel zone estimations using the CFR method indicate that the individual time-of-travel zone extents range from a radius of approximately 90 m at the Buchanan Road Well to approximately 200 m at the CPR Well, Blacksage Wells 1 through 3 and the Miller Road Well. In summary, the preliminary contaminant inventory for the ten municipal water wells indicated primarily agricultural and residential land uses within the preliminary 60-day time of travel zone for each Town well. Some commercial/ light industrial land uses were identified within the 60-day time of travel zones for a number of identified wells. It is recommended that the final 3 steps of the Well Protection Toolkit be completed to assist the city to better manage and protect drinking water sources.
