Specific health risk patterns
Arroyo Municipio, PR: 1 specific risk pattern triggered
Each pattern below combines a specific environmental exposure with a population that is more vulnerable to that exposure. When both are present at meaningful levels in Arroyo Municipio, the pattern triggers. These are the most concrete data points for documenting a significant health need in a Community Health Needs Assessment and for planning where services or community investment would land hardest.
Internally, we call these “Compound Signals.” Each is a versioned, weighted composite scored against the national distribution. The full formula and citations live on the methodology page.
Industrial emissions exposure × Surrounding population
Defend this finding — full lineage to source data5 sources cited
Industrial BurdenArroyo Municipio: 100/100 (elevated above the 70th-percentile threshold)
Arroyo Municipio: 100/100 (elevated above the 70th-percentile threshold)
TRI facility density × PFAS contamination × pesticide use × total provider access deficit. Captures cumulative industrial environmental load on the surrounding population.
Methodology. Combines three distinct industrial exposure modes (point-source releases, drinking-water contamination, pesticide use) with a generalist provider-access leg since industrial pollution health effects span multiple specialties. Methodology v1.8.0.
Threshold. Elevated when score ≥ 70th national percentile across all US counties evaluated for this signal
Peer set. All US counties evaluated for the signal (~3,222, less coverage gaps)
Components (4)
Number of EPA Toxics Release Inventory (TRI) reporting facilities in the county.
EPA — Toxics Release Inventory (TRI) via Envirofacts
Vintage: TRI 2023 reporting year · Refresh: Annual · Lag: 18 months
How it's measured. Count of facilities reporting any TRI-listed chemical release in the most recent reporting year. TRI thresholds (10K-25K lb manufacturing; 500 lb persistent-bioaccumulative) mean smaller polluters are excluded from this count.
Caveat. TRI is industrial self-report. Underreporting is documented for some sectors and chemicals; the count is a floor, not a ceiling.
Coverage. All 3,222 US counties (zero-inflated; many rural counties = 0)
Composite 0–100 severity score for per- and polyfluoroalkyl substance (PFAS) contamination in the county's drinking water and environment.
EPA — UCMR5 (Unregulated Contaminant Monitoring Rule) + ECHO
Vintage: UCMR5 sampling 2023–2025 · Refresh: Quarterly · Lag: 3–6 months
How it's measured. Composite score combining detection frequency, peak concentration relative to EPA Health Advisory Levels, and number of PFAS species detected from UCMR5 public water system sampling and ECHO enforcement records.
Caveat. UCMR5 only samples public water systems serving 3,300+ people; private well users in small or rural communities are not represented.
Coverage. Counties with at least one UCMR5-eligible PWS
Total estimated agricultural pesticide use in the county for the year, in kilograms (EPest_HIGH conservative estimate).
USGS — Pesticide National Synthesis Project (PNSP)
Vintage: PNSP 2019 (preliminary; 2018 unavailable; 2020+ unreleased) · Refresh: Annual when published · Lag: 2–3 years (and the program is on medium-low update reliability)
How it's measured. USGS PNSP estimates county-level pesticide application from USDA Census of Agriculture acreage by crop, multiplied by crop-specific application rates from proprietary surveys. EPest_HIGH is the regional-pool imputation that's conservative against undercounting.
Caveat. PNSP funding was nearly cut in 2023 and the program now publishes irregularly. 2018 has no data; 2020+ is unreleased as of methodology v1.8.0. Use with the data-quality note shown on the platform.
Coverage. 3,054 of 3,222 US counties
Total provider access deficit20%
Inverted national percentile rank of total healthcare specialists per 100K, with a 50/50 adjacency adjustment.
Methodology. Same shape as the specialty-specific deficits. Used by Industrial Burden where the relevant access dimension isn't a single specialty (industrial pollution health effects span pulmonary, cardiovascular, oncologic, and developmental medicine).
Components (2)
All active healthcare specialists in the county, normalized to population.
CMS — NPPES — National Plan and Provider Enumeration System
Vintage: Current month · Refresh: Monthly · Lag: Same month
How it's measured. NPPES registry — all specialty taxonomy codes — geocoded to practice address, summed per county, divided by Census population estimate.
Caveat. NPPES is registration-time data, not practice attestation.

Where Arroyo Municipio stands
Fewer than two displayed scores reach the screening threshold
Arroyo Municipio, Puerto Rico has these published scores: Provider Gap 0.6/100. None of the published scores reach the screening threshold of 70. Missing scores: 3. Provider Gap summarizes provider supply relative to population, including the pipeline’s access adjustments. Registration counts do not establish appointment availability or whether a practice accepts a patient’s insurance. These weighted scores support screening and comparison; a score of 70 does not mean that 70% of counties have lower scores.
Methodology: when three or more of the four major health-risk areas (pollution, chronic disease, doctor access, social and economic conditions) have displayed scores of at least 70/100, we call the pattern “multi-pillar convergence.” The scoring approach and citations live on the methodology page.
Risk profile
Arroyo Municipio compared to Puerto Rico
Four scores on a 0–100 scale. Higher values indicate greater relative burden or need within each measure. The reference line at 50 marks the scale midpoint.
Provider Gap (1) is at or below the scale midpoint of 50/100.

Environmental Factors
Air, water, and exposure indicators
Top environmental indicators for Arroyo Municipio with state and national benchmarks. Full profile covers 40+ metrics on the platform.
These indicators describe environmental conditions and potential exposure. They are not a complete record of environmental incidents in Arroyo Municipio and do not establish the cause of an individual illness. Check each measure's source and reporting period in the data-source reference and review the scoring methods.
| Indicator | Arroyo Municipio | PR avg | US avg |
|---|---|---|---|
Traffic Proximity EJSCREEN | 297,547 index ▼ -38% vs PR | 477,197 | 291,320 |

How Superfund proximity contributes
The 2024 EJSCREEN proximity indicator is 0.0963. It uses distances to proposed/final National Priorities List and Superfund Alternative Approach sites within 10 km. This is proximity context, not a measurement of heavy-metal exposure or illness.
Superfund proximity alone is insufficient to assign a composite environmental score.
