*Within Ecology, most groundwater field assessment and research is conducted by the Environmental Assessment Program. For information on Ecology policies and regulations related to groundwater, see Water Quality Program’s Groundwater information page and Water Resources Program page. For additional information regarding cleanup and regulation of groundwater at specific facilities, see the web sites for the Toxics Cleanup Program, the Hazardous Waste Program, the Nuclear Waste Program Groundwater Page, and the Waste 2 Resources (Solid Waste) Program.

Links to Information on Groundwater in Washington State

Stumped about where to find information about groundwater in your area? We’ve compiled sources of information that we often head to when conducting one of our studies.

Environmental Assessment Program Standard Operating Procedures (SOPs) for Groundwater Monitoring

Documentation describing the standardized field methods we use during our groundwater studies:

Manual Well Depth and Depth-to-Water Measurements.

Installing, Measuring, and Decommissioning Hand-driven In-water Piezometers

Groundwater Sample Collection for Analysis for General Chemistry, Metals, and VOCs (expected early 2010)

Groundwater Level Measurement using Pressure Transducers (expected early 2010)

New Items of Note, Current Events & Announcements -

NEW - The U.S. Geological Survey has recently released the findings of a nationwide study of the water quality in private domestic wells. Since domestic wells are not currently regulated by the Federal Safe Drinking Water Act, they are not routinely monitored for chemical contamination. This study reveals that more than 20 percent of private wells sampled across the U.S. contain at least one contaminant at levels of potential health concern. To see the recent press release about the study, and link to the full reports, visit: USGS Press Release - Water Quality of Potential Concern in US Private Wells.

NEW - We've recently added a number of legacy Department of Ecology Water Resources Program Open-File Technical Reports related to groundwater to our map-based groundwater study bibliography. In the near future we'll be redesigning the map interface to make it easier to find groundwater studies in your area of interest.
