Feature: Updating Data Inputs, Assessing Trends, and Evaluating a Method to Estimate Probable High Groundwater Levels in Selected Areas of Massachusetts

The USGS, in cooperation with the Massachusetts Department of Environmental Protection, conducted an update to the Frimpter method for estimating the probable high groundwater levels in Massachusetts. This method is used to inform decisions and policies about selection of suitable sites for an unmounded septic system in terms of annual groundwater-level range.

Featured Map: 2015 Groundwater Withdrawals

Starting this month, we are featuring a groundwater map in each newsletter. This month's featured map presents estimated U.S. groundwater withdrawals by state in 2015.

Field Photo

Each summer, interns join USGS offices around the Nation in support of our water studies. In this photo, USGS intern Kira Waldman conducts field work in June 2019 as part of a long-term study near Bemidji, Minnesota, to understand mobilization, transport, and fate of crude oil in the shallow subsurface. Kira is pushing a sample screen into lake bottom sediments to collect a sample of pore water from below the lake bed to help us understand how contaminants may be migrating from an historical oil release into the lake. Kira's internship at USGS was supported by the Middlebury College Center for Careers and Internships.

Water Quality and COVID-19

For the latest federal guidance on water quality and COVID-19, please refer to:

USGS priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we have shifted our operations to a virtual mode and have minimal staffing within our offices. These changes have also impacted recent and planned field work and field data collection activities.
