Book Description
The purpose of these guidelines for investigating geologic hazards and preparing engineering-geology reports, is to provide recommendations for appropriate, minimum investigative techniques, standards, and report content to ensure adequate geologic site characterization and geologic-hazard investigations to protect public safety and facilitate risk reduction. Such investigations provide important information on site geologic conditions that may affect or be affected by development, as well as the type and severity of geologic hazards at a site, and recommend solutions to mitigate the effects and the cost of the hazards, both at the time of construction and over the life of the development. The accompanying suggested approach to geologic-hazard ordinances and school-site investigation guidelines are intended as an aid for land-use planning and regulation by local Utah jurisdictions and school districts, respectively. Geologic hazards that are not accounted for in project planning and design often result in additional unforeseen construction and/or future maintenance costs, and possible injury or death.

Guidelines for Preparing Hydrogeologic and Soil Reports Addressing Suitability for Alternative Wastewater Disposal Systems in Weber County, Utah
Author: Mike Lowe
Publisher: Utah Geological Survey
ISBN: 155791642X
Category : Science
Languages : en
Pages : 13
Book Description
Many lots in Weber County presently cannot be developed because adverse site characteristics (such as soil that percolates outside acceptable rate ranges or shallow ground water) make them unsuitable for conventional wastewater disposal systems (septic tank soil-absorption systems). The Weber-Morgan District Health Department and the Utah Division of Water Quality have developed designs for alternative wastewater disposal systems that may be used in such areas if hydrogeologic soil conditions are suitable, ground- and surface-water quality will not be degraded, and humans will not be exposed to wastewater pathogens. To demonstrate conformance with these criteria, hydrogeologic and soil studies of proposed sites will need to be conducted and results submitted to the Weber-Morgan District Health Department. Suitable hydrogeologic conditions include (1) site slopes no steeper than 4 percent, (2) soil percolation rates bewteen 60 minutes/inch and 1 minute/inch (5 minutes/inch for both Ogden Canyon and Ogden Valley), (3) depth to seasonal shallow ground water at least 2 feet (0.6 m) below the bottom of soil-absorption drain-field trenches or beds and 1 foot (0.3 m) below the original ground surface (location of trenches and beds with respect to original ground surface varies with alternative system type), (4) depth to bedrock or unsuitable soil at least 4 feet (1.2 m) belowthe bottom of soil-absorption drain-field trenches, (5) topographic and geologic conditions that prevent wastewater from surfacing or reaching surface-water bodies or culinary wells within 250 days ground-water time of travel, (6) ground-water flow available for mixing in the zone of mixing in the aquifer below the site such that average nitrate concentrations will not be increased more than 1 mg/L under the anticipated wastewater loading, and (7) nitrate in high concentration zones (plumes) will not exceed 10 mg/L at any depth or location when it reaches the alternative wastewater disposal system owner's property line, as determined using a defendable solute transport model. Additionally, soil conditions should be such that wastewater will be adequately treated before reaching ground or surface water.

Investigation of land subsidence and earth fissures in Cedar Valley, Iron County, Utah
Author: Paul Inkenbrandt
Publisher: Utah Geological Survey
ISBN: 1557918910
Category : Base flow (Hydrology).
Languages : en
Pages : 122
Book Description
This 116-page report presents the results of an investigation by the Utah Geological Survey of land subsidence and earth fissures in Cedar Valley, Iron County, Utah. Basin-fill sediments of the Cedar Valley Aquifer contain a high percentage of fine-grained material susceptible to compaction upon dewatering. Groundwater discharge in excess of recharge (groundwater mining) has lowered the potentiometric surface in Cedar Valley as much as 114 feet since 1939. Groundwater mining has caused permanent compaction of fine-grained sediments of the Cedar Valley aquifer, which has caused the land surface to subside, and a minimum of 8.3 miles of earth fissures to form. Recently acquired interferometric synthetic aperture radar imagery shows that land subsidence has affected approximately 100 miĀ² in Cedar Valley, but a lack of accurate historical benchmark elevation data over much of the valley prevents its detailed quantification. Continued groundwater mining and resultant subsidence will likely cause existing fissures to lengthen and new fissures to form which may eventually impact developed areas in Cedar Valley. This report also includes possible aquifer management options to help mitigate subsidence and fissure formation, and recommended guidelines for conducting subsidence-related hazard investigations prior to development.
