Electrical Resistivity (ER) Data from the 1997 Infiltration and Tracer Field Tests

ER probes were placed both within the infiltration pond and at vertical depths ranging 0.3 m (1 ft) to 12.7 m (48 ft) within five wells, well II-5 and four of the slant wells (S-1 to S-4).

File names 0813-0827.xls, 0827-0909.xls, 0909-0917.xls, 0917-0922.xls, 0922-0926.xls, 0926-1002.xls, 1002-1006.xls, 1006-1010.xls, 1010-1014.xls, 1014-1018.xls, 1018-1022.xls, 1022-1026.xls, 1026-1029.xls, 1029-1101.xls

File type/format Excel file

Quantities measured (units) current (amps) and voltage (volts)

Number of probes 80

Probe locations Approximate probe locations are given in the file for probes located within the pond. For probes installed within wells, the file gives the well id and the distance down the borehole (ft). Coordinates of each well are given in the file well_coords.xls. (See the page on Site Characterization Data.)

Period of data collection 8/13/97 to 11/1/97

Frequency of data collection one-hour intervals

Description Each file name indicates the dates of data collections for data contained in the file. Each file contains two worksheets, one for current and one for voltage.

File names II5 graphs.xls, S1 graphs.xls, S2 graphs.xls,
S3 graphs.xls, S4 graphs.xls

File type/format Excel file

Quantities calculated (units) resistance (ohms)

Number of probes 80

Period of data collection 9/9/97 to 11/1/97

Description Each file contains four Excel charts of resistance vs. time for the well indicated by the file name. Each chart shows data for one of the pulses of the infiltration/tracer test.
