Neil Woller

Senior Hydrologist

Neil Woller is responsible for technical hydrogeologic assessment, engineering geology applications, geologic studies and resource assessments, analytical and numeric ground-water modeling, and risk and environmental assessments. Neil is a Registered Geologist in Oregon, and a Licensed Geologist, Hydrogeologist, and Engineering Geologist in Washington.

Neil has more than 20 years of experience studying water resources in Oregon for both private and public organizations. He has completed hydrogeologic studies for landfill site characterizations, railroad tunnels, water supply studies, groundwater remediation designs, and geothermal resource assessments.

Neil was a Geologist for the Oregon Department of Geology and Mineral Industries for many years. Neil mapped the geology of large parts of the Oregon Cascade Range for the Department, and many of his maps have been published by the agency. In particular, he completed detailed geologic mapping in several federally designated Known Geothermal Resource Areas. He is the author or co-author of more than 20 publications and reports related to Oregon aquifers and geology. He had a major role in the statewide geothermal energy resource assessment completed under a US Department of Energy grant. He also completed energy resource assessments for the Bonneville Power Administration and other agencies. 

Neil was a Senior Hydrogeologist with the Oregon Department of Environmental Quality’s Site Response Sec-tion. In this position, he was Project Manager for the environmental cleanup activities of some of the State’s most seriously contaminated sites.

Neil has also completed many geologic and hydrogeologic studies for the private sector. He was the Principal Investigator for a major regional landfill siting and site characterization study. The landfill has a projected maximum size of 690 acres, and is the designated solid waste disposal facility for Clark County, Washington. He has also completed environmental studies of several other landfills and unregulated solid waste disposal sites. 

Neil also directed hydrogeologic studies performed for the US Army Corps of Engineers, Bonneville Power Administration, and other government agencies. At the request of the US Army Corps of Engineers, Neil developed a groundwater resource index system as a technical contribution to the National Study for Water Management During Drought. The resource index system was designed to be applicable to any drainage basin. 

Neil also evaluated potential impacts of the proposed lowering of Umatilla Lake (the 30-mile long lake formed by John Day Dam) on water wells in the surrounding area. He developed mitigation plans and estimated mitigation costs for the US Army Corps of Engineers and the Northwest Power Planning Council.

Neil has supervised water supply studies for fish hatcheries, golf resorts, and commercial developments. He sited, designed, constructed, and tested a water well on the Spokane Indian Reservation for a new tribal hatchery that is capable of producing 1,700 gallons per minute.
