The national water quality data landscape encompasses 200+ discrete sources spanning federal agencies, 56 state and territorial programs, satellite systems, and thousands of published regulatory documents. This is the plan to connect them all.
PIN's core source stack is largely online. The roadmap was overstating outages; most previously flagged sources are live, and the remaining work is probe hardening or environment-specific configuration rather than missing integrations.

The immediate work is no longer mass recovery. It is making source-health reporting accurate across environments, adding fallback-aware probes, and tightening cache-backed resilience where public endpoints are brittle.
| Source | Data Type | Status | LOE | Action Required |
|---|---|---|---|---|
| Source Health Probes | Per-source health classification | NEW | 3 hrs | Normalize live vs degraded vs offline so timeout-only probes do not read as dead integrations |
| State Portal Proxy | Internal state discovery health | DEGRADED | 1 hr | Probe the state portal through a health-safe internal path instead of an authenticated dashboard route |
| Blue Water Baltimore | Regional harbor monitoring | DEGRADED | 1 hr | Inject Water Reporter key in each deployment environment or suppress environment-specific warning from roadmap claims |
| MD MDE ArcGIS | Integrated report and TMDL overlays | OFFLINE | 2 hrs | Mirror the cron failover chain in health checks instead of probing a single brittle ArcGIS root |
| Public vs Internal Probe Split | Health classification hygiene | NEW | 1 hr | Separate public-source availability from internal-route auth requirements so health dashboards stay truthful |
| Roadmap Status Sync | Roadmap page truthfulness | NEW | 2 hrs | Drive roadmap counts from live source-health output or periodically refresh the static inventory |
Sources identified in the national manifest not yet in the codebase. All public, no-auth APIs. Each requires a new fetch handler and registry entry. ~38 hours total LOE.

Beyond data-source onboarding, the roadmap expands PIN into a more autonomous intelligence and operations platform: higher-confidence data, earlier anomaly detection, stronger forecasting, and automated execution support.
Hot-path cache orchestration, partial refresh, and source-aware invalidation to reduce latency and stale reads.
Per-source confidence, freshness, completeness, and lineage scoring surfaced directly in user workflows.
Cross-signal anomaly detection on monitoring, compliance, weather, and infrastructure data streams.
Forecast models for impairments, contamination pressure, flood effects, and program workload.
Scenario overlays for heat, drought, flooding, salinity, wildfire smoke, and long-range watershed stress.
Operational ingestion of Earth observation imagery for HABs, turbidity, sediment plumes, and shoreline change.
Shared incident workspace connecting hazards, utilities, response teams, and executive actions in one operational thread.
Auto-generated permit, inspection, monitoring, and executive reporting packages from live system data.
Rules-driven routing, escalations, reminders, and cross-team handoffs tied to live environmental conditions.
Direct sensor, deployment, SCADA-adjacent, and field device integration with alerting and health diagnostics.
PIN is the first platform to unify all of it, show exactly where the gaps are, and fill them with fresher data from state reports, mobile sensors, and lab results.
