Sharlene Pilkey, Vice-Chair } �,-_2,u.L, . "' DATE: March 23, 1993 SUBJECT: Revised Interim Report of the Water Resource Committee Please find attached the Water Resources Committee ' s Interim Report which has been revised to address the BOCC ' s questions and comments from the Board' s December 1992 Goal Setting Retreat. The report contains two main sections: 1) an outline for the process to define the groundwater resources of Orange County and 2 ) the first year work plan and budget. The Committee finds that there is a strong need to determine the existing status of ground-water quality and quantity in Orange County. In addition, the Committee believes that it is essential that we begin to analyze the impacts of human activity on this critical resource and to develop strategies to protect it . Others have gone there before us and have lost the resource for lack of foresight and planning. It is important to note that approximately forty percent of the population of Orange County is currently dependent on wells and more areas dependent on well water are being developed rapidly. Yet we have no idea how much ground water we have, where it is located or how much population or industry we can safely accommodate. The importance of the governmental role as steward of our ground- water quality and ground-water exploitation increases in direct proportion to population growth. Stewardship becomes even more critical because of the nature of the resource. That is, ground water often does not show obvious signs of overuse or water quality degradation until redress of those problems is beyond the capability of available ground-water remediation tecnology. The occurrence of isolated incidents of ground-water depletion and degradation in Orange County is a matter of record. It is prudent to assume that occurrence of such incidents will be an accelerating phenomenon in Orange County and in every other geographic area that houses a growing and technologically advanced population. The committee believes that it is essential for the future of Orange County to continue the ground-water project. To support this assertion, we ;lope that it will be possible for one or more of its members to address the BOCC at one of its future meetings to explain details of our findings . Finally the Committee wishes to thank the County Commissioners for their strong support during our deliberation= . INTERIM REPORT OF THE WATER RESOURCES COMMITTEE MARCH 23 , 1993 ( REVISED ) INTERIM REPORT OF THE WATER RESOURCES COMMITTEE BACKGROUND To gain public participation in and support for the development of a water resources protection long range planning program, the commissioners formed a Water Resources Committee in the spring of 1992. The committee was to meet for a period of 12-18 months to determine the sources of information available to assess ground-water quality and quantity and to develop recommendations for a water resource investigation and planning process which would implement the other three objectives associated with the commissioners'Water Resource Quantity and Quality Goal. As part of its activities, the committee was to present a status report to the commissioners in time for their annual goal-setting retreat. This interim report is therefore presented for consideration. In six months of deliberation on the subject of water resources, the Water Resources Committee has reviewed a great deal of information regarding: a) Investigative processes available for use in Orange County that are currently in use elsewhere to study water resources; b) Existing programs, regulations, and policies addressing water resource issues; c) The spectrum of human activities that have the potential to affect, in varying degrees, the reliability of the water resource; d) The nature, extent and utility of both currently available and potentially obtainable information pertaining to the availability and quality of the water resource; e) The nature and reliability of available and obtainable information pertaining to known and potential threats to the water resources; and f) The costs associated with obtaining data and developing programs necessary to insure the protection of the water resource. GOAL STATEMENT Currently, nearly forty percent of Orange County residents rely on ground water as a source of drinking water. This resource is finite and is susceptible to over use, contamination, and reduction in recharge to aquifers (through impervious surface coverage of recharge areas). Better understanding of this resource is needed to effectively guide Orange County's efforts to manage, utilize and protect its ground-water resource. Orange County will seek to improve its understanding of this resource by a process of identification and evaluation. This process will build on previous surface water efforts undertaken by the County, with the ultimate goal being to develop an integrated ground- and surface- water management plan which complements the County's long-range planning process. SUMMARY OF FINDINGS Based on the information reviewed, the Water Resources Committee has arrived at a number of informal but critical conclusions or findings, summarized below, which have convinced the members of the committee to reaffirm the intent of the Commissioner's water resource investigation goal and to recommend that Orange County proceed with the investment of the financial and staff resources required to pursue the water resource investigation. • Finding 1. Potable water is a finite resource in Orange County. The availability of potable water is an issue that has both public health and economic development ramifications. A scarcity of potable water hinders the economic development potential of the County, while a decline in either quantity or quality represents a potentially serious public health problem. • Finding 2. Ground-water and surface-water quantity and quality issues are inextricably interrelated in that ground water represents the source of fifty percent of average stream flow. However, currently available knowledge and expertise on quantity, quality, protection and management issues is far less advanced than that achieved in regard to surface waters in Orange County. It is essential that future efforts to expand and develop the overall water resource database - and the level of expertise needed to evaluate and manage the resource -be focused on the ground-water resource. • Finding 3. Generally, ground water is considered a reliable source of potable water in terms of both quantity and quality. Although there have been isolated incidents reflecting ground-water quality and quantity problems, there is currently no documentation of widespread problems with either ground- water quantity or quality in Orange County. However, as the population grows and human activities increase within the County, the potential for degradation of this relatively unspoiled resource also increases. In spite of a heightened awareness of potential problem, there is very little existing documentation which addresses the vulnerability or sensitivity of Orange County's ground water to any particular threat. • Finding 4. The lack of adequate knowledge regarding the quantity and quality of ground water hinders the development of public policy or programs of citizen education necessary to insure that the resource is properly developed, managed and protected. In a similar vein, the lack of adequate ground-water knowledge forestalls the evaluation of the long term utility implications of existing and proposed development patterns within the County. • Finding 5. Communities in North Carolina and other states have begun ground-water resource investigations to establish a technical iasis for ground-water development and management programs. These investigations relied on technical expertise provided by both staff and outside experts. The US Geological Survey and other governmental/private agencies are possible contract sources of technical expertise, particularly in the effort to acquire, analyze and map technical data involving the yield, and movement and transport of the ground-water resource. • Finding 6. If the County is to develop and implement a technically sound, comprehensive ground-water resource management program, it will be necessary to provide the staff and financial resources required for an in-depth water resource investigation. It will also be necessary to allocate the resources and time to develop effective strategies, policies, and regulations required to address issues, concerns and problems which are exposed by the investigation. Important information about Orange County related to demographics, physical land use, utility service and other features relevant to ground- water resources exists in a variety of formats. This information must be consolidated into a cohesive database, preferably through the County's GIS system, so that it can be used to evaluate ground-water quantity and quality issues and implications. The process of investigation and development of strategies will require several years of effort by County staff, experts, citizen advisors and elected officials. • Findint 7. The work accomplished to this point supports the need for a ground-water investigation and management program and steps to initiate the program should be continued. Activities which have potential to adversely affect the ground-water resource continue unabated and with unknown effect. Acquisition of data and information related to these activities also continues with no concerted effort to ensure that the data is formatted and stored for ease of future integration into a cohesive water resource database. It is important that the portion of the ground-water protection and management initiative that is most readily accomplished and definitive be incorporated into an interim/preliminary strategy. Interim tasks and costs, some of which have applicability beyond the ground-water program, can be recommended to the County Commissioners for funding and integration into the County staff workplan in fiscal year 1993-94. NEXT STEPS FOR THE COMMITTEE The committee has begun to outline the elements which might be included in an investigation of the water resources of Orange County. At its current stage of development, the draft outline does not provide an adequate basis for determining or predicting the ultimate scope and cost of the effort required to define, manage and protect the County's ground-water resources. The committee's next steps would be to refine and finalize this outline, and to attach cost estimates to the various elements of the plan as follows: Develop scope of study for ground-water quality and quantity analysis • Defuie tasks and anticipated results for analysis process • Develop time and cost estimates associated with tasks • Investigate technical assistance and funding resources • Make ground-water analysis recommendations to BOCC Develop public education plan Analyze duality and utility of existing data Develop data acquisition plan Provide oversight for 1993/94 staff work plan The committee would also complete the other work outlined in its charge. In addition, the committee recommends that adoption of the following FY 1993-94 workplan as a relatively low cost method to organize and augment ongoing County activities so as to begin.to educate the public and to start a systematic collection of information needed for a water resource management and protection program. If the FY 1993-94 workplan is approved, the committee should continue its work at least through FY 1993-94. FY 1993-94 STAFF WORK PLAN - INITIAL STRATEGIES AND COST ESTIMATES The Year One Work Plan outlined below represents the portion of the water resource investigation process that can be accomplished as a preliminary phase of the overall ground-water development, management and protection program, Many of the tasks included within the outline can be accomplished at little expense, or in conjunction with other County initiatives. The Water Resources Committee would oversee this work while completing its charge. Develop public information programs • Develop public education brochures re/lated to facts about well use and maintenance, abandonment of wells, proper well locations, and common household and rural activities which can adversely affect well yields and water quality • Begin to publicize the County effort to embark on a water resource protection and management program • Develop systematic public input process for reporting ground-water resource problems and other information which would lead to an enhanced understanding of the resource Augment staff resources as required to assist in development of general data base related to water resource concerns • Utilize new interns and temporary employees to research water resource data availability and to collect and collate data for preparation for GIS entry • Utilize new interns and temporary employees with environmental health, planning and geography backgrounds and GIS experience to translate existing data for GIS database development. • Utilize new interns and temporary employees to field verify or obtain latitude/longitude or State Plane coordinate data to locate critical water resource affected activities Create interdepartmental teams to address means of acquiring water resource data in areas of common interest and expertise • Determine areas of exper*..;e in water resource-related issues, exchange information, concepts, ideas • Develop standard data collection forms for well permits and tests, special use permits, building permits, inspections, environmental impact statements, waste treatment system permits, agricultural BMPs and pesticide permits, etc. Accelerate development and implementation of County GIS capabilities • Acquire global positioning satellite technology as required to provide latitude/longitude locations of water quality and quantity activities • Improve and expand general staff accessibility to GIS equipment and training • Provide staff position for GIS systems applications specialist • Develop guidelines/procedures for enhanced, GIS compatible records/data management • Purchase GIS applications training and data developed by outside agencies as required to take advantage of GIS information applicable to Orange County water resource issues • RESOURCE ALLOCATION ESTIMATES FOR YEAR ONE WORKPLAN Work<Plan Item <;1:Resources;Needed Capital ' Resources Needed...--Staff.Time Public Info Program $ 1,000 for materials 192 hours General Database $ 15,088 2 pt-time interns*** 200 hours Inter-dept Teams $ 500 for forms 576 hours GIS-Related GPS Receiver $ 3,000 *Training $ 6,000 ($3,000 per 160 hours (80 per person) person) *GIS - Terminals $ 13,000 for equipment **Personnel $ 4,800 1128 hours ..:;. • * Accelerated from 1993-1998 CIP for GIS implementation ** Position requested under land records/GIS implementation (10% of$48,000) ***New intern positions PROPOSED PROCESS FOR GROUND-WATER RESOURCE INVESTIGATION AND DEVELOPMENT OF RESOURCE MANAGEMENT STRATEGIES The committee has begun to outline the elements which might be included in an investigation of the water resources of Orange County. The outline indicates the direction the committee is taking, even though much work remains to be done to determine the costs and timespan associated with these elements. I. Physical Environment, Land Use and Development Analysis Section I deals primarily with the process to collect and enter into the GIS data base information related to the physical environment of Orange County. These physical data include geography, current and projected land use and land cover and delineation of areas with existing or potential ground-water demand. This section also provides for the evaluation, in terms of accuracy and potential usefulness, of the data included under this section. Data acquired and mapped under this section provide a major component of the information needed to determine existing and potential ground-water demands and existing and potential adverse affects to the quality of the ground water. Though this information can be more readily collected and mapped by experts, it is within the technical capability of County staff, if staff has access to sufficient resources. In the event that the water resource investigation does not proceed from this point, the information in Section I would eventually be obtained and marl. d by County staff in response to other projects and initiatives unrelated to the water resource investigation. A. Allocate resources to collect data 1. Geography, topography 2. Geology, hydrogeology 3. Soils 4. Current/projected land use, densities, impervious surfaces 5. Municipal-type utility service areas 6. Community well/waste treatment system service ar: s 7. Vegetative ground covers (forests, lawns, crops, pastures) 8. Transportation corridors B. Allocate resources to evaluate collected data 1. Determine if data accuracy sufficient to be useful 2. De'...rmine if data is or can be formatted for development of electronic database 3. Determine if collected data is essential if found to be inaccurate or difficult to format for database development C. Allocate resources to develop mapping database 1. Develop appropriate i�rocesses/procedures for use, manipulation, and retrieval of data 2. Develop physical environment/land use/development projection database/maps H. Ground-Water Resource Analysis Section II deals primarily with the process to collect the data and create the database required to assess existing quality and availability of ground water. There is also an emphasis on determining the extent of the existing demand for ground-water supplies and for assessing the implication of existing water conservation strategies on ground-water quantity and quality. Much of the effort to collect the data related to existing ground-water quality and availability exceeds the capabilities of County staff and thus lies within the realm of water resource experts. It should be anticipated that having experts work in this portion of the data collection process represents a potential for significant out-of-pocket expense to the County. Much of the work involved in developing water demand projections can be accomplished by County staff with limited input by water resource experts. A. Allocate resources to collect data on quantity of ground water 1. Obtain and analyze the accuracy and utility of existing data related to well yield and use 2. Obtain additional data related to existing well yields, demands, etc., as required to supplement existing data 3. Obtain additional hydrogeological data, including ground-water recharge rates and recharge areas, to supplement existing general hydrogeological data as required 4. Project maximum/minimum ground-water yields 5. Create ground-water quantity database/mapping B. Allocate resources to assess existing ground-water quality 1. Obtain existing test results/water quality data from existing wells 2. Obtain supplemental data related to existing well water quality as required 3. Create database/mapping for existing ground-water quality C. Allocate resources to determine groundwater demand 1. Use existing records and statistical methods to estimate existing ground-water demands, based on current population, land use and surface water utility service areas expansion projections 2. Project future ground-water demand based on statistical analysis of land use projections, surface water utility expansion plans 3. Create database/mapping for existing and projected ground-water demand D. Allocate resources to analyze potential affects of water conservation/efficient water use management strategies on the ground-water quality and quantity Note: Analyzing the potential effects of water conservation strategies will be complex for both water resource experts and County staff. There are two divergent schools of thought on this issue, each school represented by water resource specialists holding impressive credentials. One school holds that water savings are something to be sought as a means of obvious and simple resource conservation. The other school holds that ultimate or net consumptive losses from water use are very small. This school is concerned that water conservation does not lead to a reduction in the production of sanitary wastes so that the same quantity of waste is contained in a smaller volume of water. The relationship between the volume of waste per volume of water is known as waste concentration or waste strength. The school of thought which is concerned about the relationship between conservation of water and increased waste strength theorizes that water conservation could lead to more severe waste treatment and pollution problems. III. Identify and Analyze Potential Adverse Effects to Ground-Water Resource Section III deals with the process required to identify and analyze existing and potential threats to the quality and quantity of the ground-water resource. The analytical process involved in developing ground- water vulnerability mapping, as outlined in step C, is the culmination of the initial investigative process. Development of ground-water protection and management strategies will come via addressing problems and conditions indicated by the vulnerability analyses. A. Allocate resources as required to locate and map existing and future land use activities or circumstances which are generally accepted as having potential to adversely affect ground-water quality 1. agricultural practices (agrichemical use, feedlots, animal waste lagoons) 2. hazardous material storage and spill incidents 3. legal and illegal landfills and dumps 4. underground petroleum tanks and leakage incidents 5. recharge and wellhead protection area abuse 6. on-site waste treatment and disposal are-2s B. Allocate resources as required to identify, locate and map existing and future land use activities or circumstances which have potential to adversely affect ground-water quantity 1. well overuse or overdevelopment of aquifer capacity 2. impervious surface coverage of recharge areas 3. diversion of ground water for large-scale irrigation of crop lands, golf courses, etc. C. Allocate resources as required to develop ground-water quality and quantity vulnerability analysis 1. develop ground-water quality vulnerability analysis mapping by overlaying previously developed physical environment mapping with mapping of land use activity having potential ground-water quality effects 2. develop ground-water quantity vulnerability analysis mapping by overlaying previously developed physical environment mapping with mapping of land use activity having potential ground-water quantity effects 3. investigate feasibility of using ground-water models for estimating effects of land use activities on ground-water quality and quantity IV. Develop Local Ground-Water Resource Management Strategy Alternatives Section IV begins to address problems identified by the water resource investigations. The Water Resource Committee recommends that the BOCC create a steering committee comprised of a broad spectrum of County citizens. The purpose of the steering committee is to develop a priority list and strategies for the water resource issues to be addressed. The steering committee is also to be charged with developing a program to educate the public about the findings of the water resource investigation and the methods by which problems are to be mitigated. An important facet of the public education process is a feedback loop which allows citizens input into the initial development of water resource protection strategies and into the process of evaluating the success of those strategies as well. A. Create a strategic issue steering committee comprised of a diverse cross- section of Orange County citizens B. Identify proven and potential problem areas and issues C. Prioritize proven and potential problem areas and issues D. Develop methods/alternatives for dealing with problem areas and issues 1. Identify and analyze management strategies used elsewhere for similar problems 2. Develop new or modified management strategies 3. Identify cost, resource allocations, legal actions, and regulatory actions required to implement management strategies E. Develop public education and feedback processes as required to enhance and expedite ground-water protection initiatives V. Recommend Management Strategies to BOCC Section V involves recommending a water resource protection and management initiative to the BOCC. It is likely that this process will involve much public discussion and input from citizens and elected officials and staff from all jurisdictions in Orange County. VI. Implement Management Strategies and Feedback Loop to Monitor Success of Strategies, Modify Strategies as Required Section VI involves not only implementation of management strategies, but monitoring of the success of the strategies. The monitoring can be a complex process, because it may involve not only long-term monitoring of the water resource itself, but also the monitoring of the effectiveness of the interaction of County government and its policies with citizens and other local jurisdictions. The monitoring may in some instances indicate a need for modifying strategies which are imbedded in policies and regulations, and in other instances indicate an need to develop strategies to address other water resource issues that were not recognized in the initial process.
