III. Identify and Analyze Potential Adverse Effects to Ground-Water Resource <br /> Section III deals with the process required to identify and analyze existing and potential threats to the <br /> quality and quantity of the ground-water resource. The analytical process involved in developing ground- <br /> water vulnerability mapping, as outlined in step C, is the culmination of the initial investigative process. <br /> Development of ground-water protection and management strategies will come via addressing problems and <br /> conditions indicated by the vulnerability analyses. <br /> A. Allocate resources as required to locate and map existing and future land use activities or <br /> circumstances which are generally accepted as having potential to adversely affect ground-water quality <br /> 1. agricultural practices (agrichemical use, feedlots, <br /> animal waste lagoons) <br /> 2. hazardous material storage and spill incidents <br /> 3. legal and illegal landfills and dumps <br /> 4. underground petroleum tanks and leakage incidents <br /> 5. recharge and wellhead protection area abuse <br /> 6. on-site waste treatment and disposal are-2s <br /> B. Allocate resources as required to identify, locate and map existing and future land use activities or <br /> circumstances which have potential to adversely affect ground-water quantity <br /> 1. well overuse or overdevelopment of aquifer capacity <br /> 2. impervious surface coverage of recharge areas <br /> 3. diversion of ground water for large-scale irrigation of crop lands, golf courses, etc. <br /> C. Allocate resources as required to develop ground-water quality and quantity vulnerability analysis <br /> 1. develop ground-water quality vulnerability analysis mapping by overlaying previously developed <br /> physical environment mapping with mapping of land use activity having potential ground-water <br /> quality effects <br /> 2. develop ground-water quantity vulnerability analysis mapping by overlaying previously developed <br /> physical environment mapping with mapping of land use activity having potential ground-water <br /> quantity effects <br /> 3. investigate feasibility of using ground-water models for estimating effects of land use activities on <br /> ground-water quality and quantity <br />
