The dataset generation failed because of a cast error
Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 4 new columns ({'Total Population', 'State', 'Total Missed Milestones', 'Total CWS'}) and 8 missing columns ({'MATERIAL_TO_WATER', 'RESPONSIBLE_COMPANY', 'RANK', 'STATES_INVOLVED', 'TOTAL_INJURED', 'WATER_CONTAMINATION', 'TOTAL_INCIDENTS', 'TOTAL_FATALITIES'}).

This happened while the csv dataset builder was generating data using

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).

Intended audiences

  • Public-finance credit desks — screening municipal water issuers for infrastructure-compliance exposure
  • Municipal-bond research — pre-issuance due diligence on water-utility obligors
  • Environmental-insurance underwriters — portfolio-exposure reconciliation for environmental liability lines
  • Environmental due-diligence consultancies — single-facility briefs for M&A and procurement intake
  • Institutional ESG/shareholder research — cross-program federal-record reconciliation for AGM-season engagement
  • Journalists & public-interest researchers — fact-checkable source-cited baseline for investigative work

How to obtain the full product

Three delivery tiers:

1. Single-facility compliance dossier — $2,500 (one-time, retail)
