  • Frederick Farm Well Contamination: Borehole Camera Analysis of Bedrock Structure

    Rodgers, Michael D.; Richards, Paul L.; The College at Brockport (2015-05-01)
    A borehole camera analysis was conducted at the Frederick Farm to characterize bedrock structure, quantify fractures, and establish the condition of the well casing. Through the use of a GeoVISION Jr.™ and recording equipment, footage of the camera decent was recorded for data analysis. The 5 ft well casing appeared intact and was properly constructed within bedrock. The well above the water table contained few fractures and appeared to be weathered. Flowing water was visible in the two main fractures, located on the south (5.5 ft depth) and south-western (13.5 ft depth) walls of the well respectively. The water table interface was observed at 31.125 ft depth. Below the water table the well was laden with many fractures. The size of the fractures appear to increase in size with depth, with the larger fractures approaching ~1 ft in thickness. Also noted in this interval were areas of enhanced chemical weathering, particularly below 62.5 ft. The bedrock fracture profile is indicative of a well built within heavily fractured karstic limestone.
  • Use of Ground Penetrating Radar to identify the presence and orientation of Graves in St. Brigitts Cemetery, Bergen New York

    Rodgers, Michael D.; Richards, Paul L.; The College at Brockport (2013-01-01)
    Ground Penetrating Radar (GPR) was employed to determine the location of all caskets buried at the St. Brigitts cemetery, located at the intersection of Munger Rd and Rte 33 in Bergen, New York. The study, which located 432 sites in the cemetery where caskets are buried, will assist the Diocese of St. Brigitts Church in their plans to improve the cemetery. These improvements include the refurbishment of existing headstones, the replacement of headstones where none currently exist, and the identification of land areas where new graves may be located.
