Investigation of Hydrogeologic Mapping to Delineate Protection Zones Around Springs
Author: Mark E. Jensen
Publisher:
ISBN:
Category : Drinking water
Languages : en
Pages : 72
Book Description
Methods commonly used to delineate protection zones for water-supply wells are often not directly applicable for springs. This investigation focuses on the use of hydrogeologic mapping methods to identify physical and hydrologic features that control ground-water flow to springs to aid in delineating springhead protection zones. Two public-supply springs were selected as study sites to represent diversegeologic settings. One spring discharges from fractured dolomite and one from fractures siltstone, sandstone, and shale. Hydrogeologic mapping techniques, as applied in this study, are methods for mapping geologic or hydrologic features or geophysical/geochemical signatures of subsurface features. These data are often supplemented with information from subsurface investigations to aid in extrapolating surface results to aquifer depths. In this investigation, geologic mapping, fracture-trace analysis, topographic analysis, catchment area estimation, geochemical characterization, elemental isotope studies, and a tracer study were used to locate and describe potential ground-water flow boundaries and pathways and develop conceptual models for site hydrogeology. Results were integrated to estimate the zones of contribution to each spring and evaluated for use in the delineation of potential protection zones. Data from borings and hydraulic tests supported this characterization by providing direct and indirect information regarding susurface lithology and hydraulic parameters. In these case studies, results of hydrogeologic mapping allowed development of the conceptual model for site hydrology and evaluation of potential ground-water flow controls. Although definitive ground-water flow boundaries suitable for delineation of practicable protection zones could not be identified at either site, these techniques provided sufficient information to support an initial evaluation of potential protection zones. These results would also serve as a strong basis for additional investigations if more detailed or reliable delineations were warrented.

Landscape and Quaternary Environmental Change in New Zealand
Author: James Shulmeister
Publisher: Springer
ISBN: 9462392374
Category : Science
Languages : en
Pages : 342
Book Description
This book brings together an overview of the recent geological history, active earth and biological processes and human settlement of New Zealand. Topics covered include the very active neotectonic and volcanic setting. Mountain geomorphic processes are examined and new ideas about landsliding are highlighted. The exceptional sedimentary archives of the Whanganui Basin are also presented. As one of two land masses that extend into the southern mid-latitudes, New Zealand is ideally located to investigate changes in Southern Ocean climate. Related to this, mountain glaciation in New Zealand is a focus in global climate change debates. New Zealand also has a unique biota due to its long isolation and is the last major land mass to be settled by people. Advances in DNA technologies have revolutionised our understanding of the histories and processes involved. The book provides a comprehensive review of existing work and highlights new ideas and major debates across all these fields.
