SmartScore MQI / Environmental application
PR Health Index
River data made easier to understand.
An environmental application of Minedco’s SmartScore MQI framework.
Created by Minedco, PR Health Index brings sampling information from Potomac Riverkeeper Network (PRKN) and other public sources into a shared view of changing river conditions.
Complex monitoring. Clearer meaning.
A clearer view of
the river we share.
PR Health Index turns fragmented water-quality results into a simple, color-coded view of conditions by location and over time.
Built on Minedco’s SmartScore MQI framework, it uses water-specific index definitions to make monitoring information easier to interpret. The value comes from connecting the result to its source, its history, and the conditions around it.
One site.
More context.
A recent result, a recurring pattern, and a gap in sampling tell different stories. See each location in its own time context, rather than treating the river as one uniform condition.
Many sources.
One clearer view.
Bring monitoring information from river organizations, municipalities, and public agencies into a common view, while keeping the source and collection dates visible.
Trends worth
investigating.
Distinguish a broader recovery from a persistent local concern. Explore changes around rainfall and identify exceptions that deserve closer attention.
A river-wide trend can hide a problem at one site. A single reading can miss a spike and recovery between sampling days. PR Health Index makes those differences easier to see, helping monitoring teams ask better questions and communicate what the available evidence shows.
PR Health Index uses its own water-quality definitions and is not a guarantee of safe water or a replacement for laboratory results and official advisories. Check the sample dates, legend, and source information. Observed patterns do not establish a pollution source or cause.
In practice / June 2026
The map shows where.
Context helps explain the pattern.
Bring sampling history and rainfall together, then look for what changed across the river and what happened differently at one site.
- Monday, June 22Afternoon storms
- Tuesday, June 23Steady rain
- Wednesday, June 24Sampling results
A pattern across several areas.
The June report identified elevated bacteria readings in Rock Creek tributaries, several upper Potomac sites, and parts of the lower river following the rain. It was more than a single-site event.
An exception worth noticing.
Georgetown / “the Wall” did not show the same June 24 spike in the DC Water data. That difference matters when comparing a broader river pattern with an individual location.
Multiple sources. One understandable picture. PR Health Index helps reveal shared patterns and local exceptions, so monitoring teams can decide where to look more closely.
Historical example from the June 26, 2026 PR Health Index report. Rainfall provides context, not proof of cause. The map above preserves the report’s site colors; it does not assign a new color from this commentary.
A foundation for the next stage
Better context.
Better monitoring questions.
Minedco has proposed an expanded monitoring and analysis program to PRKN. The aim is to turn a clearer view of the data into a more coordinated way to investigate change.
Proposed expansionThe broader joint program is under discussion. It is not an approved or deployed monitoring network.
Compare across sites and sources
Extend analysis across monitoring locations, municipalities, and data providers, accounting for differences in sampling schedules and coverage.
Connect measurements to their setting
Study sampling history alongside rainfall, available overflow reporting, and site context to develop more focused research questions.
Evaluate continuous indicators
Design sensor pilots paired with laboratory samples to test what additional monitoring could reveal between collection days.
Build a baseline for change
Establish consistent comparisons over time to help assess restoration work or infrastructure improvements and explain the findings to communities and funders.
Make complex environmental
data easier to use.
