In many regions, monitoring and maintaining water quality face significant challenges due to unauthorized data reporting, tampering, and fraud. Traditional methods often lack real-time oversight and transparency, which can result in inaccurate data, regulatory non-compliance, and compromised public health.

Our project addresses these issues by leveraging blockchain technology to ensure water quality data’s integrity and transparency. Here’s how it tackles the problems:

1.	Unauthorized Meter Reporting: By implementing a smart contract, only authorized IoT devices can report data to the blockchain. This ensures that data integrity is maintained by preventing unauthorized devices from skewing the records.
2.	IoT Meter Tampering Detection: The system uses Exponentially Weighted Moving Averages (EWMA) to predict expected water volume. Deviations beyond a set threshold trigger alerts, enabling prompt action to investigate potential tampering or fraud.
3.	Regulatory Compliance: Smart contracts are established between regulators and organizations to ensure that water processing meets regulatory standards. This facilitates automatic enforcement of criteria and compliance checks.
4.	Data Transparency and Security: Data stored on the blockchain is immutable, providing a transparent and secure record of water quality and usage. This ensures that all data is reliable and verifiable.
5.	Real-Time Monitoring and Alerts: The project features a real-time dashboard that visualizes water usage and tampering status. Additionally, TensorFlow is used to calculate tampering probabilities, while Twilio and SendGrid provide SMS and email alerts for immediate notification of anomalies.

By integrating these features, our project enhances the accuracy and transparency of water quality monitoring, making regulatory compliance more efficient and ensuring that public health is safeguarded against data fraud and tampering.
