Subsequent well locations, based on the seismic work showed substantial improvement, with flow rates over six gpm in one of the wells. RayfractВ® seismic refraction tomography software allows reliable imaging of subsurface velocity structure including faults, strong lateral velocity variation and other velocity anomalies. Prior to the geophysical investigation, and based on results of the previous investigations, the threshold for a well installation to be considered a success was a sustained flow rate of 0.75 gpm. This software allows analysis of seismic refraction data using conventional wavefront and plus-minus methods as well as tomographic inversion based on the Waveform Eikonal Tomography (WET) method. Data were processed using the Rayfract software package, from Intelligent Resources, Inc.

The remainder of the lines had geophone spacing at 10-foot intervals. The receivers were placed at 5 feet spacing on seven of the ten lines. Seismic data were acquired with a 48-channel Geometrics Geode system using a sledge hammer as the seismic energy source and 4.5 Hz geophones as receivers. Rayfract is a simulation tool using Smooth Inversion Tomographic Method based on physically.for P-wave and S-wave surveys. Data were acquired along ten profile lines, ranging from 115-470 feet in length. Seismic refraction tomography (SRT) was selected as the most appropriate method for the site, based on the desired depth of penetration and numerous site constraints, including infrastructure, deep well casings, and surface modifications (parking lots, roads, riprap, and vegetated areas), especially those in areas of particular interest. The purpose of the survey was to investigate the depth to water table, depth to bedrock, and especially to characterize variations in bedrock seismic velocity along profile lines that might provide insight into more permeable zones that were anticipated at shallow depths and which could exhibit enhanced groundwater flow. RayfractВ® software allows reliable imaging of subsurface velocity with modeling of propagation of seismic first break energy. Subsurface velocity structure imaging for geotechnical engineering and exploration.

The seismic data was processed by using computer software such as Ras-24, Rayfract and surfer. RayfractВ® Seismic Refraction/Borehole Tomography software Intelligent Resources Inc. A surface geophysical survey was performed in a portion of Naval Station Newport that was impacted by historical releases of chlorinated solvents. to the site made accurate data collection more difficult.
