| Abstract/Description or Keywords | A Well Protection Plan has been developed for the seven municipal water supply wells operating at the Powerhouse Springs well field. This is done in general accordance with steps laid out in the Province’s “Well Protection Toolkit,” which are as follows: 1. Define the Well Protection Area 2. Identify Potential Contaminants 3. Develop Management Strategies and Contingency Plans 4. Implement, Monitor, and Evaluate the Plan At the outset of this work, there was limited regional scale information about the Ring Creek aquifer, which is the source of groundwater to the Well Field. Therefore, the first objective was to define the aerial extent of the aquifer and identify predominant recharge sources, based on geological site reconnaissance, geochemical and isotopic analysis, and a hydrogeological water balance utilizing pertinent climate and hydrological data. The resulting conceptual model was incorporated into a numerical groundwater flow model, which was used to define well capture zones for the Well Field under current operating conditions. This preliminary work, is summarized in Piteau’s report entitled “Hydrogeological Assessment for Well Protection” dated May 2014. The Well Protection Plan presented herein defines a Groundwater Protection Zone (or GPZ), based on the one-year capture zone defined in the Hydrogeological Assessment. Land use activities within the Groundwater Protection Zone are reviewed, and associated hazards to groundwater quality and quantity are identified. The level of risk associated with each hazard is evaluated, and management options to mitigate these risks are suggested. These options were further refined based on feedback received from various stakeholders / user groups that attended a workshop on September 28, 2013. This Well Protection Plan also outlines contingency measures for possible contamination scenarios. ii. PITEAU ASSOCIATES ENGINEERING LTD. Our vision is that this document will assist the community in making land management decisions that are cognizant of the value and vulnerability of their water resource, and that it will be reviewed and modified on a regular basis as land use and community needs change over time. |
