Audit Analysis

The Gambia Safe Water project (GS1247 VPA 227) is a Gold Standard energy-efficiency project with VVB-confirmed additionality and recent baseline reassessment, but is undermined by a project-specific baseline, a 0% leakage deduction with contradictory historical justification, no stated buffer pool, and a high volume of material findings (21 CARs, 6 CLs) including repeated water-quality failures at boreholes. Multiple cross-document contradictions in ERR figures, usage rates, and fNRB method reduce confidence in the data reliability.

Red Flags

  • 48 boreholes failed water-quality testing across multiple quarters (19 in Q1 2021, 11 in Q2 2021, 18 at initial testing), raising questions about sustained safe-water delivery and actual usage rates
  • Leakage deduction is 0% in the 2024 verification report but the PDD originally proposed 5%; the justification shifted from 'deemed negligible' to 'quantified' between the 2023 and 2024 reports without clear reconciliation
  • Five Forward Action Requests (FARs) remain open, including evaluation of SDG indicators at VPA level and submission of an fNRB report
  • ERR figures differ substantially between the 2023 and 2024 verification reports (claimed: 60,000 vs 36,083; verified: 65,901 vs 36,083), indicating a significant downward revision
