This data set is a point data layer representing well yield at 7,287 bedrock wells in the Nashoba Terrane in central and eastern Massachusetts. The data were compiled from databases of the Massachusetts Department of Environmental Protection and U.S. Geological Survey. The data are described and interpreted in U.S. Geological Survey Scientific Investigations Report 2012-5155 by DeSimone and Barbaro (2012).

This data release contains well yield and ancillary data for 7,287 bedrock wells used in an analysis of bedrock well yield in the Nashoba Terrane and surrounding area in eastern and central Massachusetts. The data release also contains Geographic Information System (GIS) data layers of lineaments delineated from aerial photographs and digital elevation data for a part of the Nashoba Terrane study area. Ancillary data consist of well depth; bedrock geology, surficial geology, topographic setting, and wetlands at the well location; distance of the well to hydrologic and geologic features; and distance of the well to lineaments. The data were interpreted in U.S. Geological Survey Scientific-Investigations Report 2012-5155, and a data layer of estimated well yield in 200 by 200 meter grid cells throughout the Nashoba Terrane and surrounding area, based on kriging of yield data from the 7,287 wells, is included in the data release. The data release contains 4 separate items: 1. Well yield and ancillary data for 7,287 bedrock wells 2. Well locations 3. Lineaments in a part of the study area 4. Estimated bedrock well yield from kriging of well yield data These data are associated with the following publication: DeSimone, L.A., and Barbaro, J.R., 2012, Yield of bedrock wells in the Nashoba terrane, central and eastern Massachusetts: U.S. Geological Survey Scientific Investigations Report 2012-5155, 74 p., available at http://pubs.usgs.gov/sir/2012/5155

This data set contains information on well yield and ancillary information at 7,287 wells in the bedrock aquifer in the Nashoba terrane in central and eastern Massachusetts. Well yield was compiled from records in databases and files of the Massachusetts Department of Environmental Protection and U.S. Geological Survey. Ancillary data include well depth; bedrock geology, surficial geology, topographic setting, and wetlands at the well location; distance of the well to hydrologic and geologic features; and distance of the well to lineaments. The data in this data release were interpreted in U.S. Geological Survey Scientific-Investigations Report 2012-5155.

A dataset of well information and geospatial data was developed for 426 U.S. Geological Survey (USGS) observation wells in Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. An extensive list of attributes is included about each well, its location, and water-level history to provide the public and water-resources community with comprehensive information on the USGS well network in New England and data available from these sites. These data may be useful for evaluating groundwater conditions and variability across the region. The well list and site attributes, which were extracted from USGS National Water Information System (NWIS), represent all of the active wells in the New England network up to the end of 2017, and an additional 45 wells that were inactive (discontinued or replaced by a nearby well) at that time. Inactive wells were included in the database because they (1) contain periods of water-level record that may be useful for groundwater assessments, (2) may become active again at some point, or (3) are being monitored by another agency (most discontinued New Hampshire wells are still being monitored and the data are available in the National Groundwater Monitoring Network (https://cida.usgs.gov/ngwmn/index.jsp). The wells in this database have been sites of water-level data collection (periodic levels and/or continuous levels) for an average of 31 years. Water-level records go back to 1913. The groundwater-level statistics included in the dataset represent hydrologic conditions for the period of record for inactive wells, or through the end of water year 2017 (September 30, 2017) for active wells. Geographic Information Systems (GIS) data layers were compiled from various sources and dates ranging from 2003 to 2018. These GIS data were used to calculate attributes related to topographic setting, climate, land cover, soil, and geology giving hydrologic and environmental context to each well. In total, the data include 90 attributes for each well. In addition to site number and station name, attributes were developed for site information (15 attributes); groundwater-level statistics through water year 2017 (16 attributes); well-construction information (9 attributes); topographic setting (11 attributes); climate (2 attributes); land use and cover (17 attributes); soils (4 attributes); and geology (14 attributes). Basic well and site information includes well location, period of record, well-construction details, continuous versus intermittent data collection, and ground altitudes. Attributes that may influence groundwater levels include: well depth, location of open or screened interval, aquifer type, surficial and bedrock geology, topographic position, flow distance to surface water, land use and cover near the well, soil texture and drainage, precipitation, and air temperature.

This dataset describes water-level and associated data for wells open to various hydrogeologic units of Delaware that were used to create potentiometric surface contours for selected aquifers that underlie both the Coastal Plain of northern and central Delaware, and southern New Jersey. Water-level measurements were collected during October 2013.

This dataset contains the well location, construction information, and water-level measurements for 983 wells measured during a groundwater-level synoptic of 10 confined aquifers of the New Jersey coastal plain. Groundwater-level measurements were made from October 2013 to January 2014. Well-location and water-level data are publicly available from the U.S. Geological Survey's National Water Information System (NWIS).
