| Sample type | n | Water quality parameters average values (lower to upper) | ||||||
|---|---|---|---|---|---|---|---|---|
| pH | TDS (mg/L) | Turbidity (NTU) | DO (mg/L) | Chloride (mg/L) | Nitrate (mg/L N) | Ammonium (mg/L N) | ||
| GW | 4 | 6.11 (5.55–6.40) | 370 (335–409) | 3.45 (< 0.1–11.3) | 7.94 (6.92–10.05) | 78.0 (51.4–106) | 112 (14.1–224) | 0.376 (0.299–0.465) |
| SW | 9 | 6.84 (5.76–7.22) | 193 (42–420) | 8.04 (1.4–18.5) | 6.07 (5.61–8.14) | 33.5 (1.16–74.8) | 26.8 (2.96–179) | 0.212 (0.091–0.347) |
