Arsenic Variability in Water-Supply Wells

The USGS, in cooperation with the Town of Seabrook, New Hampshire and a private well owner, is assessing the variability of arsenic over multiple time scales. A network of three wells is being used to monitor changes in arsenic, arsenic species, a host of other chemical constituents, and the distribution of ages of groundwater entering the wells. The wells—one domestic bedrock aquifer well, one...

Recharge Estimates for Maine: 25-year Average, Range, and Uncertainty, 1990-2015

The USGS Soil-Water-Balance model (SWB) has been used to estimate potential recharge across the State of Maine. The average and range (minimum and maximum) of annual recharge were estimated for the 25-year period from 1990 to 2015. Datasets of estimated recharge and the modeled uncertainty in the recharge estimates are available for download.

Geospatial Dataset of Wells and Attributes in the New England Groundwater Level Network, 2017

The drought of 2016 affected hydrologic conditions throughout New England. Responses of USGS groundwater observation wells to this event, however, were not uniform and were sometimes markedly different from site to site. Although USGS scientists were able to provide explanations for most of these situations, the event highlighted the need for additional well information to develop quantitative and...
