Summary

A total of 119 passive seismic soundings were collected with Tromino (MoHo s.r.l.) 3-axis seismometers in the Fountain Creek area to partially refine alluvial aquifer thickness (depth to bedrock) estimates, particularly over known or suspected paleochannels. Data were collected during June 21-24, 2021 with a team of 4-5 people, each equipped with a Tromino Blu or Tromino 3G passive seismometer. A subset of the data included measurements made for shear velocity calibration; this included data collected at 10 well sites where depth to bedrock was available from driller's logs, and 3 sites above cutbanks where bedrock outcropped and the thickness of alluvial sediments could be directly measured. Data were processed using a publicly [...]

Purpose

The Fountain Creek Alluvial Aquifer consists of alluvial sand and gravel deposits along the present-day channel of Fountain Creek south of Colorado Springs, CO and is a productive water supply for the communities of Security, Widefield, and Fountain. Several paleochannels, formed from erosion into the local shale bedrock and later filled with alluvial sediments, are believed to be important conduits for groundwater flow and potentially, contaminant transport. These data were collected to test the HVSR method for refining estimates of alluvial aquifer thickness in the Fountain Creek, CO area. More accurate aquifer thickness maps can be used to improve groundwater flow models in the area.
