H. Ground-Water Resource Analysis <br /> Section II deals primarily with the process to collect the data and create the database required to assess <br /> existing quality and availability of ground water. There is also an emphasis on determining the extent of <br /> the existing demand for ground-water supplies and for assessing the implication of existing water <br /> conservation strategies on ground-water quantity and quality. Much of the effort to collect the data related <br /> to existing ground-water quality and availability exceeds the capabilities of County staff and thus lies within <br /> the realm of water resource experts. It should be anticipated that having experts work in this portion of the <br /> data collection process represents a potential for significant out-of-pocket expense to the County. Much of <br /> the work involved in developing water demand projections can be accomplished by County staff with <br /> limited input by water resource experts. <br /> A. Allocate resources to collect data on quantity of ground water <br /> 1. Obtain and analyze the accuracy and utility of existing data related to well yield and use <br /> 2. Obtain additional data related to existing well yields, demands, etc., as required to supplement <br /> existing data <br /> 3. Obtain additional hydrogeological data, including ground-water recharge rates and recharge areas, <br /> to supplement existing general hydrogeological data as required <br /> 4. Project maximum/minimum ground-water yields <br /> 5. Create ground-water quantity database/mapping <br /> B. Allocate resources to assess existing ground-water quality <br /> 1. Obtain existing test results/water quality data from existing wells <br /> 2. Obtain supplemental data related to existing well water quality as required <br /> 3. Create database/mapping for existing ground-water quality <br /> C. Allocate resources to determine groundwater demand <br /> 1. Use existing records and statistical methods to estimate existing ground-water demands, based on <br /> current population, land use and surface water utility service areas expansion projections <br /> 2. Project future ground-water demand based on statistical analysis of land use projections, surface <br /> water utility expansion plans <br /> 3. Create database/mapping for existing and projected ground-water demand <br /> D. Allocate resources to analyze potential affects of water conservation/efficient water use management <br /> strategies on the ground-water quality and quantity <br /> Note: Analyzing the potential effects of water conservation strategies will be complex for both water <br /> resource experts and County staff. There are two divergent schools of thought on this issue, each <br /> school represented by water resource specialists holding impressive credentials. One school holds that <br /> water savings are something to be sought as a means of obvious and simple resource conservation. The <br /> other school holds that ultimate or net consumptive losses from water use are very small. This school <br /> is concerned that water conservation does not lead to a reduction in the production of sanitary wastes <br /> so that the same quantity of waste is contained in a smaller volume of water. The relationship between <br /> the volume of waste per volume of water is known as waste concentration or waste strength. The <br /> school of thought which is concerned about the relationship between conservation of water and <br /> increased waste strength theorizes that water conservation could lead to more severe waste treatment <br /> and pollution problems. <br />
