Levels and limits are as printed in the utility’s report (“limit” is the EPA MCL, action level, residual limit, or secondary guideline that applies to that row; “ND” = not detected). Utilities publish these reports annually — we re-check every covered utility each July, after the federal publication deadline. Detected doesn’t mean dangerous — most detections sit far below their limits. This is education, not medical advice.
Your tap, if it were a bottle
How Arlington Water Utilities water stacks up against the bottled aisle
Same minerals, same units — the tap values below come from the utility’s report, placed next to the closest match in our bottled-water database.
| Mineral | Your tap | Closest bottled match |
|---|---|---|
| Total dissolved solids | 177 mg/L | Highland Spring at 170 mg/L |
| Calcium | 30 mg/L | Acqua Panna at 32.2 mg/L |
| Magnesium | 3.6 mg/L | Waiakea at 3.6 mg/L |
| Sodium | 23.7 mg/L | Buxton at 24 mg/L |
| Sulfate | 39 mg/L | Staatl. Fachingen at 39 mg/L |
| Chloride | 18 mg/L | Ferrarelle at 16.9 mg/L |
| Potassium | 4.4 mg/L | Crazy Water at 4.7 mg/L |
Tap values are the headline levels from the utility’s annual report (often a highest or average figure); bottled values are label- or report-derived. A closest match is a numeric comparison, not an equivalence or an endorsement.
