Build a Desalination Intake Sampling and Lab Follow-Up Workspace

Turn unusual intake readings into proposed sampling visits and laboratory evidence requests. Track unresolved samples and prepare review packets without diagnosing algal blooms or recommending chemical doses.

Desalination Environmental Compliance Engineer

Import synthetic intake readings and fictional sampling thresholds.

Identify exceedances and prepare sampling requests with cited readings.

Track sample collection, laboratory evidence, and unresolved follow-up tasks.

Export an intake review packet without operational commands.

Reading timeline, sample request queue, laboratory attachment panel, and engineer review export.

Create normalized synthetic readings, fictional sampling thresholds, sample identifiers, and laboratory records. These are not measured GCC data. Starter examples below are synthetic. They are not downloaded records.

WaterTAP treatment modeling WaterTAP documents treatment modeling. This application prepares evidence for later modeling, without deriving organic loads or chemical doses.

haystack, pydantic, fastapi. Haystack retrieves linked sample evidence. Deterministic rules create requests from supplied thresholds. Use a currently available model for evidence-linked summaries, not water-quality diagnosis.

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.

Uses thresholds supplied with each fixture.

Creates a request when either supplied threshold is exceeded.

Shows missing laboratory evidence instead of diagnosing blooms.

Exports evidence packets and pending tasks.

Use synthetic records. Do not diagnose water safety, recommend chemical doses, or operate equipment. Use mock external writes. Require human review before any real deployment.
