Active Groundwater Monitoring Network Water Level Event Type

Stations from Station Header which have an Active/Physical status in the SDMS data model (hydro_stn_evnt table), and which have an event type of "Water Level". Groundwater is the source for over 97% of the public and domestic drinking water supplies in SJRWMD. In addition, over 73% of industrial/commercial and 66% of agricultural water needs are supplied by groundwater sources. The 2000 District Water Supply Plan indicates that the population within SJRWMD is projected to increase by about 50%, to nearly 5.2 million, by the year 2020. Total water demand is projected to increase about 35% by 2020, to nearly 1.85 billion gallons per day (Vergara 2000). As the demands on water resources increase, it is important to have an ongoing program to provide the data and information needed to assess groundwater level and quality conditions and understand what information can be obtained from groundwater monitoring. Existing and anticipated sources of groundwater may not be adequate to supply water for all existing and future needs through 2020 without causing unacceptable impacts to water resources and related natural systems. Potential impacts include declines in groundwater levels and quality, reduction in spring discharge, increases in seawater intrusion, harm to native vegetation and wetlands, and interference with existing legal users. Projections of future water resource conditions were developed with modeling techniques that used the best information available. The accuracy of the model projections can be improved in areas where there is currently a lack of data. As a result, improved groundwater monitoring well networks were devised, addressing both regional and subregional data needed for long-term water supply planning and water resource protection. Data obtained from the well networks increase our understanding of the hydrogeologic, climatic, and human factors that affect water resources, and this information is used to assess the effectiveness of water management programs. Groundwater monitoring is administered in the through the Water Resources Assessment section, a Field Services (well construction) section, and a Geophysical Logging section. WRI is responsible for data collection from the network wells. The objectives of the Water Resources Assessment section are to: Design, construct, and maintain water level and water quality monitoring well networks Evaluate and refine the networks to optimize the spatial and temporal data collection Evaluate and analyze the data collected from the networks using statistical, geostatistical, graphical, and mapping methods to produce useful information Assess the effectiveness of the information derived from the networks to meet current and future water management needs Distribute and publish the network data, information, and interpretations as required by users for water supply planning, minimum flows and levels, consumptive use permitting, and other District programs.本数据集选取SDMS数据模型（hydro_stn_evnt表）中状态为“活动/物理”的站点表头对应的站点，且其事件类型为“水位”。 在SJRWMD辖区内，公共及民用饮用水供应中超过97%来自地下水。此外，辖区内73%以上的工业/商业用水以及66%的农业用水需求亦由地下水供给。 《2000年辖区供水规划》显示，到2020年，SJRWMD辖区内人口预计将增长约50%，达到近520万；总需水量预计将增长约35%，达到近18.5亿加仑/日（Vergara，2000）。 随着水资源需求持续攀升，建立长效项目以获取评估地下水位与水质状况所需的数据及信息，并明确地下水监测可提供的相关信息，显得尤为关键。若不对水资源及相关自然系统造成不可接受的影响，截至2020年，现有及规划中的地下水水源或不足以满足所有当前及未来的用水需求。潜在影响包括地下水位与水质下降、泉水排放量减少、海水入侵加剧、本土植被及湿地遭到破坏，以及对现有合法用水户的用水权益造成干扰。 未来水资源状况的预测是基于现有最优信息，通过建模技术生成的。在当前数据匮乏的区域，模型预测的准确性可通过补充数据得到提升。为此，研究人员设计了优化后的地下水监测井网，以满足长期供水规划与水资源保护所需的区域及次区域数据需求。 从监测井网获取的数据有助于加深我们对影响水资源的水文地质、气候及人为因素的理解，而这些信息可用于评估水资源管理项目的实施效果。地下水监测工作由水资源评估科、现场服务（井体建设）科以及地球物理测井科负责统筹实施。WRI负责该监测井网的数据采集工作。 水资源评估科的工作目标如下： 1. 设计、建设并维护水位与水质监测井网； 2. 对监测井网进行评估与优化，以实现时空数据采集的最优化； 3. 采用统计、地质统计、绘图及制图方法，对从监测井网采集的数据进行评估与分析，以生成实用信息； 4. 评估从监测井网获取的信息在满足当前及未来水资源管理需求方面的有效性； 5. 根据用户需求，分发并公开监测井网的数据、信息及解译结果，以支撑供水规划、最小流量与水位管控、用水许可审批及辖区其他相关项目的开展。
