Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole.The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs).
The Department of Ecology began a vehicle inspection program in 1982, requiring vehicles registered within the state to be inspected for emissions quality. The program ended on December 31, 2019, following a 14-year phase-out approved by the state legislature in 2005 as air quality in Washington cities had improved to above federal standards.
The Oregon Department of Environmental Quality (DEQ) is the chief regulatory agency of the government of the U.S. state of Oregon responsible for protecting and enhancing the state's natural resources and managing sanitary and toxic waste disposal. The agency employs approximately 700 scientists, engineers, technicians, administrators, and ...
Mar. 7—National and state officials are zeroing in on the West Plains as PFAS well-testing begins this week. Speaking from the center of the exposure in Airway Heights, EPA Regional ...
Ecology is asking the Airport to sign an order that may well put it in legal jeopardy with the federal government. We believe this approach by Ecology is arbitrary, capricious and unlawful," he wrote.
[1] [2] These documents include maps, field notes and well logs relevant to geothermal exploration and development. Some of the information was originally gathered for use by the oil industry. [ 3 ] NGDS facilitates the digitization of this data, and ensures that data from various sources is stored in a compatible format to facilitate ...
May 28—Free PFAS well testing has restarted on the West Plains as the EPA and state Department of Ecology determine the scope of contamination. Testing conducted by the government agencies first ...
Density logging is a well logging tool that can provide a continuous record of a formation's bulk density along the length of a borehole.In geology, bulk density is a function of the density of the minerals forming a rock (i.e. matrix) and the fluid enclosed in the pore spaces.
