The program was developed in response to the Groundwater Quality Monitoring Act of 2001 (AB 599), and is implemented by SWRCB in coordination with the USGS and LLNL. The Springand Fall Groundwater Monitoring Program s, are semiannual field efforts to document the status of wells, obtain water level measurements, and collect groundwater samples. Aquifers and monitoring network scale selection. The data collected will help resource managers to understand the location of water resources, whether there is evidence of fluids from oil and gas sources in groundwater, and the pathways or processes that contribute to the mingling of water and petroleum resources. Trends in annual minimum, mean, and maximum groundwater levels for 205 monitoring wells were analyzed across three regions of the system (East, Central, West Central) for four time... Water-level trends spanning 20, 30, 40, and 50 years were tested using month-end groundwater levels in 26, 12, 10, and 3 wells in northern New England (Maine, New Hampshire, and Vermont), respectively. Real-time monitoring provides groundwater data which can be acted on and reported in a timely manner. This almost doubled the number of water-level sites in the NGWMN. Groundwater monitoring network monitors the main aquifers in a study zone under hydrogeological solicited and un-solicited conditions. The owner or operator must indicate in groundwater monitoring strategies or plans the statistical method that will be used in the analysis of groundwater monitoring results (North Dakota Administrative Code (NDAC) 33.1-20-13-02). The U.S. Geological Survey (USGS) measures more than 20,000 wells each year for a variety of objectives as part of Federal programs and in cooperation with State and local agencies. The U.S. Geological Survey serves the Nation by providing reliable hydrologic information used by others to manage the Nation's water resources. Pressure transducers and automatic dataloggers are ideal for long term or continuous monitoring of groundwater levels. The USGS is instrumental in the distribution of water to citizens and commerce.
