Well water in Hood County, Texas
In Hood County, none of 59 tested well samples exceeded the EPA limit for fluoride, based on public data from Texas Water Development Board Groundwater Database.
59 individual samples from 28 wells, 1956 to 2011. Data refreshed September 9, 2026.
TWDB samples an ambient monitoring network of wells on a rotation, so these describe aquifers, not a survey of homeowners' tests.
What individual samples found
Each row summarizes every public sample for that contaminant inside Hood County. Above limit means above the EPA maximum contaminant level; where EPA has no enforceable limit, the row shows a health guideline or nuisance level instead.
| Contaminant | Samples | Detected | Above limit | Median | Highest | Limit | |
|---|---|---|---|---|---|---|---|
| Fluoride 1956 to 2011 | 59 | 92% | 0% | 0.3 | 3.2 | 4 mg/L EPA limit | |
| Chloride 1956 to 2011 | 59 | 100% | no limit | 23 | 1,249 | 250 mg/L nuisance level | |
| Sodium 1956 to 2011 | 59 | 100% | no limit | 63 | 313 | 20 mg/L health guideline | |
| Iron 1960 to 2011 | 15 | 73% | no limit | 104 | 2,600 | 300 ug/L nuisance level |
Sampled fewer than 10 times, too few to summarize: Gross alpha (5), Radium (226 + 228) (8), Lead (8), Arsenic (8), Copper (8), Nitrate (4), Uranium (1), Manganese (8).

What this means
Among contaminants with a federal limit, no tested sample in Hood County came back above it. That is reassuring, but sampling is uneven: wells that were never tested are not in this data.
Chloride and Iron are widespread in local groundwater. They are mainly a staining and taste problem, but high manganese also carries a health advisory for infants.

Contamination sources on record in Hood County
TCEQ records 38 leaking underground storage tank sites in Hood County, among 41 regulated sites in total. Groundwater does not follow property lines, so a well within a few hundred feet of one of these is worth testing for what that site could release.

Non-detects count as samples and are treated as zero when computing medians. Exactly at the limit counts as not above it. A sample belongs to the town containing the well's reported coordinates.
