GS1247 VPA 224 - The Gambia Safe Water

Audit Analysis

The Gambia Safe Water project (GS1247 VPA 224) is a Gold Standard borehole-based safe water project with VVB-confirmed combined additionality and no reported reversal events. However, the record contains ten cross-document contradictions—including a material discrepancy between the PDD's 5% leakage deduction and the verification report's 0%—along with 21 closed corrective actions and five open findings, which collectively moderate confidence in the project's data integrity and claim robustness.

Project Description

Red Flags

• ⚠Leakage deduction contradiction: the 2025 PDD specifies a 5% leakage deduction while the 2024 verification report applies 0%, creating a potential over-crediting gap of up to 5% of verified ERRs.
• ⚠Five open findings (FAR 01–05) remain unresolved, including the absence of a VPA-level fNRB report and unaddressed SDG indicator evaluation.
• ⚠Ten contradictions across the document set (ERR figures, usage rates, crediting period dates, additionality test type, fNRB method, benefit sharing, leakage) indicate inconsistent record-keeping between the PDD, monitoring reports, and verification reports.
