Weather + hydrology context for Brazoria County

Composite operating context — active hazards, hydrologic features, surface-water condition, and infrastructure footprint — pulled from cached snapshots only.

Active hazard footprint
0 active alerts

No NWS-driven alerts active in the cached water-summary feed. Drought + precipitation context land once those snapshots are committed.

No sewer overflow rows in the 30-day window.

Hydrology features
8 TWDB features

Drinking-water exposure
364 SDWIS violations

81 public water systems with cached health-based violations since 2023-04-01. 27,622 people served by those systems.

Analytics snapshot

Risk trend from committed snapshots

Uses the committed county-history artifact only. Atlas does not backfill imaginary periods; if a previous snapshot is missing, this panel says so.

Interpretation

What changed and why

Brazoria County is currently driven most by permits in the county explorer stack, while the committed analytics lane classifies it as high pressure + high risk.

Across the latest two committed snapshots, both the county risk score and pressure score are unchanged, so the analytical read is about persistent position rather than a new spike. The county is steady across the latest committed comparison window.

High pressure + high risk
This county sits above the current statewide median on both the pressure and risk axes in the committed scatter snapshot.
Grounding and caveats

County analytics are derived from committed SDWIS, ACS county population, surface-water-quality, and TWDB hydrology snapshots. History appends one real snapshot per run and never fabricates prior periods.

  • countyRiskScore is the statewide 0-100 normalization of summed SDWIS DWRS raw scores per county.
  • pressureScore is the statewide 0-100 normalization of impaired segment counts per 100k residents when population is available; otherwise it falls back to raw impaired segment count.
  • Rank deltas compare the newest county-history snapshot against the immediately preceding real snapshot.
  • Both axes are normalized to a 0-100 statewide range for stable chart consumption.

County ↔ operator navigation

Move from county stress to named operators

County rankings show where signal concentrates. Operator pages show which named permittees and applicants are currently visible inside that signal.

The strongest visible crosslinks here come from UNDINE TEXAS ENVIRONMENTAL LLC and AM BIDCO OPERATIONS LLC. Use those pages to inspect county concentration, case posture, and permit roster.
  • • County page: risk, hydrology, and statewide rank context.
  • • Operator page: county footprint, open CID case posture, and pending permit roster.
  • • Permit view: county-scoped transaction list for the current public snapshot.
