Groundwater Study Services — INMACOM Program

The hydrocensus will identify and map existing boreholes and groundwater use in the INMACOM Basin.

• Scope of Work and Specific Tasks for the Assignment

In order to achieve the objective of the assignment, the specific tasks will be undertaken, which include but not be limited to:

• Produce a groundwater situational analysis report: The activity includes characterising and conceptualising the aquifer(s) in the identified RBOs through a document review.

• Source existing groundwater data: The activity includes sourcing data from various country databases.

• Conduct hydrocensus: Recognised field procedures and sampling protocols will be followed during the groundwater level measurements and field analysis for selected physicochemical parameters. Provision must be made for forty (40) samples to be collected for hydrochemical analysis in the INMACOM basin on an agreed spatial density with SADC-GMI. The hydrocensus should collect at least the following data:

• Borehole location data

• Any known BH identification / reference number from national, basin or water supply organization

• Boreholes use

• Groundwater levels

• Borehole abstractions and information on boreholes that have water meters.

• Groundwater quality analysis in the field for selected physicochemical parameters such as Temperature, Electrical Conductivity (EC), TDS, pH, DO, and Alkalinity at boreholes visited.

• Collection of 40 groundwater samples for chemical analysis (macro- and trace-constituents) and submission to an accredited laboratory

• Characterisation of current and potential sources of pollution and associated contaminants of concern.

• General conditions/status of boreholes and issues of concern.

• Hydrocensus report: This task includes data recordings and analysis. This task will assess the data obtained from the various countries' databases and the hydrocensus. The groundwater data will be uploaded to the SADC-GMI Groundwater Information Portal. The analysis will also identify possible problem areas associated with groundwater and present mitigation options.

• Eligibility

This consultancy targets individuals with more than 8 years of proven experience conducting similar groundwater studies/assessments, which may include groundwater monitoring within the RBO contexts, preferably in the SADC region. The successful consultancy firm/team must demonstrate experience in at least three projects undertaking hydrocensus activities.
