Gro for GooD VES (Vertical Electrical Soundings) Data, Kwale County, Kenya (NERC grant NE/M008894/1)
Results of Vertical Electrical Soundings (VES) study conducted in Kwale County, Kenya in July and August 2017 by University of Nairobi and Water Resources Management Authority as part of the Gro for GooD project (https://upgro.org/consortium/gro-for-good/) to determine the existence of deeper aquifers.

Data Quality
Direct Current (DC) electrical resistivity method is commonly used to delineate aquifer composition, groundwater, bed-rock, fresh and salt intrusion (Robinson and Coruh, 1988; Burger, 1992; Telford et al. 1990; method detailed in Lowrie, 2007). VES was conducted in SSW-NNE direction parallel to the geological strike in the coastal area using ABEM SAS 1000 terrameter. Maximum current electrode separation was 1,000m. The array type was Schlumberger. Readings were repeated to get the value with the least standard deviation to increase data quality. Sites were identified in all the major geological formations and the survey conducted transverse to geological strikes. A total of thirty five (35) points were probed in a N-S orientation with current electrode separation of 500m. Potential was boosted at 32m, 80m and 250m during data acquisition to increase uniformity.
