# Leaking petroleum storage tank sites in Williamson County, Texas

> 182 LPST cases on the Commission's file in Williamson County, 1 of them still open, with 730 registered storage tanks. Checked against the TCEQ file of 2026-08-21.

## LPST sites in Williamson County

The Commission has recorded **182** leaking petroleum storage tank cases in Williamson County — 0.6% of the Texas total — and **1** of them have no closure date.

### The open cases

**1** of the 182 cases in Williamson County are still
open — 0.5%. The oldest of them was reported in
**2025**, and 1 were reported in 2015
or later.

That spread matters more than the count. An open case from the
1990s usually means a long remediation that was never formally closed; one
from last year means something recent. The file records the two dates and
nothing else — not the substance, not the extent, not what is left to
do. [How to read an open case](/open.md).

### When they were reported

A reporting date is not the date a tank started leaking — it is the date someone found out. In Williamson County the pattern follows the state’s:

| Reported in | LPST cases | Share |
|---|---|---|
| [1980s](/decade/1980.md) | 14 | 7.7% |
| [1990s](/county/williamson/1990.md) | 107 | 58.8% |
| [2000s](/decade/2000.md) | 22 | 12.1% |
| [2010s](/decade/2010.md) | 22 | 12.1% |
| [2020s](/decade/2020.md) | 8 | 4.4% |

### Tanks still in the ground in Williamson County

The Commission’s other file — delivery certificates —
records **730** storage tanks in Williamson County, of which
730 are marked in use. **143** of them sit at a
facility that also has a leak case on record.

That last number appears in neither file: it only exists once
the two are joined on the facility number, which is what this site does.
