Nitrate stays low
Good news Nitrate strips have read 2 mg/L at the creek on every visit.
| Sampling point | Readings | Lowest, mg/L | Highest, mg/L | Years |
|---|---|---|---|---|
| IWLAR Seneca Creek | 17 | 2 | 2 | 2025–2026 |
| IWLAR Lake | 17 | 0 | 0 | 2025–2026 |
Test strips read in coarse colour steps, so a steady 2 means the creek sits in a low band rather than at exactly 2. That is well below the EPA's 10 mg/L drinking-water limit for nitrate as nitrogen. Strips cannot show small changes, so nitrate is unlikely to explain the loss of sensitive animals on this evidence.
