The first half of this training will cover the instruments used to collect water level data and field data collection at groundwater sites. The second half will cover groundwater data processing in AQUARIUS Time-Series and highlight workflows and the application of some data corrections and edits.
Provide the history of the Network, current funding opportunity, and a request for USGS scientists to evaluate and update sites in the Network. Candice Hopkins will provide more information regarding steps to update the NGWMN portal in a companion presentation.
The National Groundwater Monitoring Network (NGWMN) is a compilation of selected groundwater monitoring wells from Federal, State, and local groundwater monitoring networks across the nation. The NGWMN is designed to be a curated network of wells that are of known quality and can provide insight to groundwater araciality. The NGWMN Data Portal provides access to data in the Network; monitoring locations must be added to the network through a manual process. Each Water Science Center can select wells they deem appropriate for inclusion in the NGWMN. This session will cover criteria for wells to include in the NGWMN, give tips on how to determine if wells should be added or deleted, and review the application that can be used for this process.
This presentation will cover groundwater site establishment, characterization, operation and maintenance, and quality assurance. The talk will also discuss instrumentation used to collect water level data and considerations for measurement frequency.
This presentation will discuss what well integrity is and its importance as a foundation of quality assurance at groundwater well sites. The talk will highlight office and field-based approaches to evaluating well integrity including use-cases.
The goal of this open-forum/listening session is to provide groundwater expertise for Q&A and to promote interaction and networking within the USGS groundwater community
Groundwater flow meters that measure horizontal flow direction and velocity have been used by the USGS in a variety of investigations across the country. Traditionally, these instruments required on-site operation and supported investigative studies of contaminant plumes (such as TCE and PFAS) to aid in site characterization and remedial planning, as well as to evaluate aquifer test responses and production well influence. As part of the NGWOS Illinois Basin Study, groundwater flow meters have been deployed for long-term, telemetered monitoring at two testbed sites to help characterize groundwater flow and direction to assess groundwater–surface water interactions between streams and nearby agricultural areas. Recently, as part of the NGWOS Research and Development sub-program, work has commenced to develop a heat pulse flowmeter that is capable of measuring flow direction and velocity in 3-dimensional space rather than being limited to the horizontal plane. This presentation will provide an overview of available technologies, guidance on proper deployment and operation, case studies, best management practices, and research and development of a new multi-dimensional instrument.
