Build a Desalination Brine Discharge Environmental Compliance Monitor — implementation

## Build
Correlate seawater desalination outfall salinity and temperature telemetry against marine environmental protection guidelines. Produce automated regulatory compliance dossiers and recommend dynamic brine dilution flow setpoints.

## User
Desalination Environmental Compliance Officer

## Workflow
1. Ingest outfall conductivity, temperature, and ambient marine monitoring buoy data in near real-time.
2. Calculate mixing zone thermal plume dissipation and excess salinity using WaterTAP brine property routines.
3. Evaluate regulatory threshold exceedances (+3 degrees C delta-T or +2 ppt salinity at mixing zone boundary).
4. Generate a structured bilingual environmental compliance audit report and cooling water dilution recommendations.

## Interface
Environmental monitoring dashboard displaying mixing zone salinity contours, buoy telemetry graphs, and compliance alert logs.

## Data
Generate synthetic continuous sensor records representing outfall discharge salinity, temperature, and background coastal currents.
Starter examples below are synthetic. They are not downloaded records.

## Source
[WaterTAP treatment modeling](https://raw.githubusercontent.com/watertap-org/watertap/main/README.md)
Leverages WaterTAP seawater and concentrated brine property calculations to model density and salinity mixing behavior.

## Tools
evidently-ai, fastapi, pandas.
Evidently AI monitors telemetry drift and outfall metric distributions over time to identify chronic sensor drift and environmental threshold breaches.
Local Python runtime with hosted Claude API for formatting official bilingual compliance filings.

## Deliverables
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

## Acceptance
- Detects salinity anomalies exceeding +2.0 ppt above background seawater salinity at edge of mixing zone.
- Calculates recommended auxiliary cooling water dilution rates to restore compliance within 2 hours.
- Produces dual-language compliance summaries suitable for municipal environmental protection agencies.

## Safety
Environmental compliance calculations are advisory; outfall pump adjustments and discharge throttling require chief plant chemist authorization.
Use mock external writes. Require human review before any real deployment.
