Drinking water quality, GA
Georgia contaminants ranked by SDWA exceedance
Which regulated contaminants exceed their maximum contaminant level (MCL) most often across Georgia's community water systems, per EPA's Six-Year Review sample-level dataset (2012-2019). Source data is public; every value is citable.
Sample data. SYR4 ingest is in flight on prod; this page renders deterministic placeholder data until the V1 importer lands the GA cohort.
Top 5 contaminants by exceedance count
| Contaminant | Category | Samples | Above MCL | Munis affected |
|---|---|---|---|---|
| total trihalomethanes | disinfection byproduct | 1,240 | 63 | 31 |
| haloacetic acids (HAA5) | disinfection byproduct | 980 | 53 | 25 |
| lead | lead copper | 2,100 | 30 | 17 |
| arsenic | inorganic | 720 | 21 | 8 |
| nitrate (as nitrogen) | inorganic | 1,850 | 8 | 7 |
For citizens
Look up your own water system by name on the muni search, then read the drinking-water quality band on its profile page for per-contaminant readings + MCL ratios.
For chemical suppliers
Contaminants near or above MCL signal treatment-chemical procurement pressure. Lane intelligence pairs this with per-chemical bid timing on the supplier tier.
