Lillian Enterprises — U.S. Federal Compliance Dataset (Sample Release)

Publisher: Lillian Enterprises LLC · Knoxville, Tennessee · Est. 2026 Contact: msa@lillianenterprises.com · https://lillianenterprises.com License: Creative Commons Attribution-NonCommercial 4.0 (CC BY-NC 4.0) Release: April 2026 (Sample / Public Surface)

What this is

A cross-program U.S. federal compliance dataset reconciled at the facility level via EPA's FRS REGISTRY_ID. The full dataset consolidates records from:

SDWA — Safe Drinking Water Act violations, Lead Service Line inventories, UCMR5 PFAS detections
NPDES — National Pollutant Discharge Elimination System permits and enforcement
RCRA — Resource Conservation and Recovery Act hazardous-waste generation and handling
ICIS-AIR — Integrated Compliance Information System air-program violations
TRI — Toxics Release Inventory 5-year trend
NRC — National Response Center incident reports (water contamination, material-reached-water events)

Each figure in the full product is footnoted to the originating federal-database row. All source material is public. The value of the format is the cross-program consolidation, not any single program's data.

What's in this sample

Three representative tables plus the methodology overview:

File	Rows	Description
`sample_top100_community_water_systems.csv`	100	Top 100 community water systems by SDWA Lead Service Line Inventory missed milestones. Columns: Rank, PWSID, System Name, State, City, Population Served, Service Connections, Missed Milestones.
`sample_state_summary.csv`	61	State-level rollup: Total CWS count, aggregate population served, cumulative missed LSL milestones.
`sample_nrc_repeat_offenders.csv`	130	Top NRC incident-report repeat offenders by `RESPONSIBLE_COMPANY`, with water-contamination event counts and material-reached-water counts.
`methodology.pdf`	4 pp	Overview of the reconciliation pipeline, data sources, source-citation convention, and refresh cadence.

The full April 2026 release covers 695+ facilities with the complete cross-program matrix (single-facility, multi-program, state-rollup, and sector-rollup views).
