How Puerto Rico compares across two EPA disclosure measures
The highlighted point is Puerto Rico. The vertical axis is the share of tracked water systems with at least one health-based SDWIS record; the horizontal axis is TRI-reported pounds per facility on a logarithmic scale so the full state distribution stays readable. The crosshairs use the portal’s published national benchmark medians.
This matrix compares disclosure rates, not toxicity, exposure, current compliance, or drinking-water safety. A lower position on either axis is not a safety rating; use the underlying facility and water-system records for context.
According to EPA TRI, SDWIS, and Superfund NPL extracts, Puerto Rico (PR) lists 121 TRI-reporting facilities disclosing 25.4M lbs of toxic releases. The same extracts list 26 Superfund sites and 402 EPA-regulated water systems, of which 324 carry health-based SDWIS violation rows. PlainEnviro's composite environmental health score for Puerto Rico is 31/100 (grade F), benchmarked against all U.S. states on chemical release intensity, drinking-water health violations, Superfund site burden, and water violation rate. This is a percentile-derived composite from federal disclosure counts, not a clinical health-risk assessment.

Puerto Rico's profile joins three independently maintained EPA programs into one statewide record: the Toxics Release Inventory (TRI, EPCRA Section 313 industrial disclosures), the Safe Drinking Water Information System (SDWIS, Safe Drinking Water Act compliance), and the Superfund National Priorities List. Each program uses its own reporting cadence and facility-identification scheme; PlainEnviro joins them by matched facility and system location rather than a shared federal ID, so a site absent from one program is never assumed absent from another. The counts below reflect the portal's rebuild as of August 2026.
Activity clusters in counties such as Caguas Municipio, Ponce Municipio, San Lorenzo Municipio, which account for the highest combined facility, water-system, and Superfund presence. Monitoring and reporting violations are not included in the SDWIS counts shown here.
Every figure reflects the public regulatory record as filed with the U.S. Environmental Protection Agency and is not weighted for toxicity, geographic footprint, or population exposure. A state can rank high in any individual metric because of industrial history, naturally occurring contaminants in source water, or simply the number of reporting facilities, not because current residents face unsafe conditions. Drill into any county or water system below for the full disclosure record.

Frequently Asked Questions
How many TRI facilities are in Puerto Rico? ▼
Puerto Rico has 121 facilities that report to the EPA Toxic Release Inventory (TRI). These facilities have collectively reported 25.4M lbs in total toxic chemical releases. TRI data is self-reported annually by facilities that manufacture, process, or use listed toxic chemicals above threshold amounts.
Does Puerto Rico have Superfund sites? ▼
Yes, Puerto Rico has 26 sites on the EPA Superfund National Priorities List (NPL). Superfund sites are contaminated locations identified for long-term cleanup under the EPA Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
What does EPA SDWIS list for drinking water in Puerto Rico? ▼
Puerto Rico has 402 EPA-regulated water systems in the Safe Drinking Water Information System (SDWIS) extract used here. 324 water systems have a health-based violation row (MCL exceedance) in this historical extract. A past registry row is not a current drinkability verdict. For current utility conditions, contact the local water utility or the Puerto Rico drinking water program. Source: EPA SDWIS.
What environmental data is available for Puerto Rico? ▼
PlainEnviro provides three categories of EPA environmental data for Puerto Rico: Toxic Release Inventory (TRI) data covering 121 industrial facilities, Safe Drinking Water Information System (SDWIS) data for 402 water systems, and Superfund National Priorities List (NPL) data for 26 contaminated sites.
How does Puerto Rico compare to other states on EPA disclosure counts? ▼
Puerto Rico has 121 TRI facilities with 25.4M lbs in total releases, 26 Superfund sites, and 2,862 water system violations on record. These are federal disclosure counts; they are not toxicity-weighted or population-adjusted risk scores. Source: EPA TRI, SDWIS, and Superfund NPL databases.
What is Puerto Rico's environmental health score? ▼
PlainEnviro's composite environmental health score for Puerto Rico is 31/100 (grade F). This score combines four percentile-benchmarked dimensions from EPA federal extracts: chemical release intensity per TRI facility, drinking-water health violation rate from SDWIS, Superfund site burden relative to industrial activity, and overall water violation rate. Scores are benchmarked against all 56 U.S. states and territories. When a dimension lacks data, its weight redistributes to the remaining dimensions so the score never deflates from missing inputs. This is a registry-count composite, not a clinical exposure or health-outcome assessment.

About This Data
This page aggregates environmental data from three EPA programs for Puerto Rico: the Toxic Release Inventory (TRI) for industrial chemical releases, the Safe Drinking Water Information System (SDWIS) for water quality, and the Superfund National Priorities List (NPL) for hazardous waste cleanup sites.
PlainEnviro presents this data without advocacy framing. Numbers reflect reported data and may not capture all environmental activity. For specific health or environmental concerns, contact your state environmental agency.
What to do with Puerto Rico's data
Use this state profile as a starting point, then drill into the specific dataset that matters to you.
- Check the 121 TRI facilities reporting in Puerto Rico for the largest reported releases near a specific county. View facilities
- 324 water systems in the state have a recorded health-based violation, check if yours is one of them. Check water systems
- See how Puerto Rico compares to other states on releases, water violations, and Superfund sites. State rankings
Reported data reflects what facilities and agencies disclose to the EPA; it is not a complete measure of environmental risk or a substitute for local guidance.
Use and verify this record
Puerto Rico's profile brings together EPA release, drinking-water, and Superfund records. It reports the underlying programs without making a health or environmental-risk determination.
State environmental figures are computed directly from EPA data. The methodology records the joins, definitions, and refresh cadence for each program.
PlainEnviro renders public EPA records directly from its data pipeline; no figure on this page is typed in by an editor. See the editorial standards and corrections policy for how source changes and reported errors are handled.
