The initiative is funded by Generation U (therein called the client) and is oriented at providing enough quality water for consumption use at the church premises. 1.1 Background Strata Imaging (U) ltd was assigned this contract by the client to carry-out a detailed hydrogeological survey upon success then drilling can be proceeded by the driller of the client’s choice after a successful survey. The Borehole-siting process entailed carrying out detailed geophysical survey in order to identify potential spots within the premises having sustainable groundwater potential for drilling borehole(s) with yields of at least 500 litres per hour. The project is oriented at provision of adequate safe water at (or within proximal walkdistance to beneficiary church as a means of providing enough safe water for consumption, in so doing improving the living standards through reducing the level of waterborne related diseases). Objective The main objectives of this groundwater exploration survey were: 1. Identification of potential groundwater spots or areas for successful drilling of One (1) hand-pump borehole (s) with a yield of at least 500 liters per hour. 2. Strategically locating the water source at (or in proximal walk-distances) to the beneficiary residential area of power generation project. 3. Appropriate integration of water source into the fragile sanitation and Working conditions of the beneficiary church in order to minimize inter-groundwater contamination, thus ensuring sustainable safety of the water. 4. Contribute to attainment of millennium-development-goals (MDG) in conformity to international-water-and-sanitation sphere standards oriented at: provision of sustainable safe-water, in proximal walk-distances to the beneficiary project. 1.3 Goal The overall objective of this Hydro-geophysical survey is to ascertain the availability of adequate safe and sustainable underground water to enable success in the drilling process. August 2021 Generation U Groundwater exploration report in Busia district. 2.0 Implementation The project was implemented in 4 phases namely: Phase1: Inception studies, area(s) familiarization, and Reconnaissance. Phase2: Desk studies (analysis of existing water sources data, Maps and Aerial photo interpretations) Phase3: Detailed Geo-physical surveys and Phase4: Geophysical data analysis, documentation and reporting. This report includes details of all activities carried out in each phase, field data sets, GISlocation maps, hydro-geological, geophysical analyses and interpretations, suitable site selections, recommendations per site, and conclusions. The report briefly highlights both technical hindrances or social difficulties encountered, and general remarks. 2.1 Familiarization and Reconnaissance surveys This was carried out for all areas in which the surveys were planned. It involved: technicalvisual assessment of geographical layout of the areas, patterns of locations of existing boreholes (other water sources), drilling-success rate(s), awareness creation interviews with leaders, and beneficiary’s preferential locations considering proximity, walk distances and the security zone. During the process, resistivity profiles lines were planned and the resistivity VES’s were carried out at anomaly points (low resistivity values) to cover the area. GPS coordinates of VES points were taken. 2.2 Desk study This phase involved literature review and analysis of existing hydro-geological data(if any) to establish vital geo-physical parameters, challenges, typical VES shapes and characteristics, anomaly ranges, lithological data, typical drilling depths, and success rates. In addition, to increase accuracy of resistivity profiling, GIS-aided ground-proofing techniques that entailed: Aerial photographic interpretation, structural lineament identification and superimposition of geo-referenced aerial photo images onto topographic maps was carried out. This was significant in fitting GPS coordinates of profiling terminals (start /finish coordinates), and orientations onto area. August 2021 Generation U Groundwater exploration report in Busia district. 2.3 Detailed Geo-physical survey. The geophysical survey involved geo-electric Resistivity measurements by running profiles to detect anomalous zones along the profile. In addition, parallel profiling was done at sections where anomalies were detected as confirmatory tests with a more precise potential length. Vertical Electrical Soundings (VES’s) were made at prioritized spots to have an insight on the vertical layering, hence detect the presence and size of fractured / weathered formations as potential zones of ground water abstraction. In all Resistivity-profiling patterns, profiles were run to cut through the anticipated topographic lineaments at acute angles, thus anomalous readings were expected along approaching the topographic structural lineaments. Note Resistivity-profiling was carried out, using Sting R1 Earth Resistivity meter (made in U S A), and all profiles were configured to: Shrumberg-set up with: ½ AB=90m , 1/2MN=5.0m, 2.5m and inter-station intervals of 5m. GPS-receivers were used to obtain coordinates of VESs, the maximum ½ AB was 120m, while ½ MN of: were varied from 0.5m, to 5m, and finally to 20m in order to ensure reliable signal strength. 2.4 Geophysical data analysis, documentation and reporting This involved data entry, analysis and modelling of field data aided by geophysical Resistivity measurement software. Hydro geological modelling and interpretation of VES’s was done using Winsev™, EarthIMAGER-1D™ and VES™ software. Details of geophysical results per site are annexed. (Annex_1) 3.0 Summary of the survey results. A survey was carried out in the priotised areas; one profile was carried out, 2VESs were assessed at anomaly points, and VES-2 was taken as the first priority. 3.1 Recommendation. August 2021 Drilling should be done according to the survey report. Collapsing formation up to 20m. Boulders are anticipated between 25 to 60m, the driller must take caution Maximum drill depth is 70 to 75m. Generation U Groundwater exploration report in Busia district.
