The Hydrogeologist will work under the direct supervision of the Project Manager and will be responsible for conducting hydrogeological assessments, groundwater investigations, and technical analysis to support the planning, design, development, and rehabilitation of sustainable water supply systems under the AHF project.
The position will assess groundwater availability, aquifer conditions, water quality, and potential borehole/water-well sites and provide technical recommendations for groundwater-based WASH interventions. The Hydrogeologist will support field surveys, geophysical investigations, test drilling, borehole construction, pumping tests, water quality assessments, and interpretation of hydrogeological data.
The Hydrogeologist will work closely with the Project Manager, WASH team, Design Engineer, contractors, local authorities, communities, and other relevant stakeholders to ensure that groundwater interventions are technically sound, safe, sustainable, and appropriate to local conditions. The position will also contribute to technical documentation, monitoring, reporting, and quality assurance throughout the project cycle.
Duties and Responsibilities:
· Conduct hydrogeological assessments and groundwater investigations for proposed WASH water supply interventions.
· Identify and assess potential sites for boreholes, wells, and other groundwater sources.
· Conduct or support geological, hydrogeological, and geophysical field surveys as required.
· Assess groundwater availability, aquifer characteristics, recharge conditions, groundwater levels, and potential risks.
· Review available geological, hydrogeological, topographical, and groundwater data and prepare technical recommendations.
· Support the selection of suitable borehole/well locations based on technical, environmental, and community considerations.
· Supervise and provide technical guidance during borehole drilling and well construction activities.
· Monitor drilling activities, lithological logging, borehole depth, casing, screen placement, gravel packing, sealing, and other technical works.
· Review and verify drilling logs and hydrogeological information provided by drilling contractors.
· Support borehole development, well cleaning, and appropriate completion procedures.
· Plan, supervise, or support pumping tests and recovery tests to determine borehole yield and aquifer performance.
· Analyze pumping-test and groundwater data and provide recommendations regarding sustainable abstraction rates.
· Support groundwater quality assessments and coordinate water sampling and laboratory testing.
· Review water quality results and identify potential risks related to drinking-water use.
· Identify potential sources of groundwater contamination and recommend appropriate protection measures.
· Provide technical recommendations for borehole pumps, water abstraction systems, and related WASH infrastructure in coordination with the Design Engineer.
· Ensure groundwater interventions consider sustainability, water availability, environmental risks, and potential impacts on existing water users.
· Support the preparation and review of technical designs, specifications, BOQs, and cost estimates related to groundwater components.
· Conduct regular field visits to monitor hydrogeological and groundwater-related activities.
· Monitor contractors and technical teams to ensure compliance with approved designs, specifications, and required quality standards.
· Identify technical problems, risks, deviations, and implementation challenges and recommend appropriate corrective measures.
· Maintain accurate records of borehole locations, coordinates, depths, drilling logs, groundwater levels, test results, water quality results, and other technical information.
· Prepare hydrogeological assessment reports, technical reports, site visit reports, and groundwater monitoring updates.
· Support the development and maintenance of groundwater databases and technical records.
· Coordinate with the WASH Design Engineer, WASH Officer, Project Manager, contractors, local authorities, and communities on groundwater-related activities.
· Provide technical information and guidance to project staff and relevant stakeholders on groundwater resources and sustainable water use.
· Support community awareness on proper use, protection, and sustainable management of groundwater sources.
· Ensure appropriate consideration of gender, disability inclusion, protection, environmental risks, and the needs of vulnerable communities in groundwater interventions.
· Support testing, commissioning, completion, and technical handover of groundwater facilities.
· Conduct or support post-construction monitoring of boreholes and groundwater sources.
· Ensure activities comply with approved project plans, organizational policies, WASH standards, and relevant donor requirements.
· Perform other relevant technical duties assigned by the Project Manager.
