Expression of Interest For Recruitment Of A Consulting Firm For Monitoring Water, Soil, And Air Quality

Expression of Interest for Recruitment of a Consulting Firm for Monitoring Water, Soil, and Air Quality This notice aims to recruit a specialized laboratory to carry out sampling campaigns and analyses related to: Water quality Soil quality Air quality within the project intervention area. 2. Specific Objectives Monitor the evolution of physicochemical parameters during both the construction phase and the operation phase Verify compliance of pollution levels with national and international standards Propose corrective measures in case of threshold exceedance Measure key atmospheric parameters in the study area, including: Suspended particles (PM10, PM2.5) Nitrogen oxides (NOx) Sulfur dioxide (SO) Carbon monoxide (CO) to establish baseline conditions and assess impacts during construction and operation Assess noise levels generated by project activities by identifying critical points and high-exposure periods, comparing them with standards, and proposing mitigation measures 3. Scope of the Assignment The selected laboratory will be responsible for: Defining sampling points in coordination with the project team Collecting samples of: Water (groundwater and surface water) Soil Ambient air measurements Using standardized methods to ensure sample integrity 4. Parameters to be Monitored Analyses will cover physical, chemical, atmospheric, and acoustic parameters to assess environmental conditions: Physico-chemical parameters: Temperature Salinity pH Dissolved oxygen Turbidity Conductivity Suspended solids Nutrients (nitrates, nitrites, ammonium, phosphates) Chemical contaminants: Heavy metals (mercury, cadmium, lead, arsenic, copper, zinc, nickel, chromium) Total hydrocarbons Polycyclic aromatic hydrocarbons (PAHs) Pesticides Air quality: Suspended particles (PM10, PM2.5) Sulfur dioxide (SO) Nitrogen oxides (NO/NOx) Carbon monoxide (CO) Other relevant pollutants Acoustic parameters: Ambient noise levels including indicators such as: Leq, L10, L50, L90 (measured according to applicable standards) 5. Intervention Area and Frequency Sampling will be carried out at project sites located in Brakna West region, including: Boghé Dar El Barka Ould Birem Dar El Avia [Disclaimer: The above text is machine translated.
