Evaluation Of Production-Well Performance In Response To Formation Clogging And Rehabilitation For The Keweenaw Bay Tribal Fish Hatchery, Brock O. Howell
Evaluation Of Production-Well Performance In Response To Formation Clogging And Rehabilitation For The Keweenaw Bay Tribal Fish Hatchery, Brock O. Howell
Dissertations, Master's Theses and Master's Reports
Temporally, the KBIC (Keweenaw Bay Indian Community) Hatchery wells have manifested general trends of declining specific capacity and higher energy consumption due to mineral precipitation in and around the production wells. Monitoring data, laboratory water analyses, and downhole video logging have confirmed that naturally occurring minerals are precipitating and clogging the screens and, likely, the surrounding formations. The reduction in fluid pressures in and around the well-screens from active pumping wells is typical but, ultimately alters the geochemical and physical conditions such that dissolved minerals precipitate on and around the well-screens, therefore, effectively clogging the well. The clogging from mineral …

Located in Antrim County, Michigan between the coasts of Torch Lake and Lake Michigan is a hydrocarbon plume that has impacted surrounding residential wells. The plume is comprised of benzene, toluene, ethylbenzene, and xylenes (BTEX) and primarily resides in the shallowest groundwater aquifer. The plume is suspected of having originated from an underground storage container that was removed in 1979. A conceptual model was developed for the site, comprising of a simplified hydrogeological model. Groundwater modeling was performed using Aquaveo's groundwater modeling software (GMS). PEST parameter calibration was performed on the hydraulic conductivity and recharge values using data from surrounding …
