GS1247 VPA 72 Lango Safe Water Project

Audit Analysis

The Lango Safe Water Project has VVB-confirmed additionality and no reversal events, but is undermined by an extensive list of material findings, 23 corrective actions, multiple cross-document contradictions, and a 0% leakage deduction that conflicts with the original PDD's 5% proposal. The verified usage rate (99.56%) exceeds the assumed 90%, which is conservative for crediting but the fNRB calculation used an incorrect tool version, raising reliability concerns. Overall, the project's data quality and documentation integrity are significantly below the standard expected for a Gold Standard-registered project.

Project Description

Red Flags

• ⚠23 corrective actions and 20+ material findings reported in the verification report, including fNRB calculation using an incorrect Tool 30 version and multiple ER calculation inconsistencies across boreholes
• ⚠Leakage deduction of 0% in the verification report contradicts the PDD's original 5% proposal, and the justification shifted from 'deemed negligible' (PDD 2013) to 'quantified' (VR 2023) without a clear quantified basis
• ⚠FPIC status is contradictory: the monitoring report (2024) states it was not conducted, while the validation report (2025) states it was conducted
• ⚠Grievance mechanism books were being used as guest books rather than for their intended purpose, indicating the mechanism is not functioning effectively in practice
• ⚠Water quality contamination (red worms) observed at the Apuru borehole during the site visit, with no confirmed remediation
