| Water Source | pH | Specific conductivity (μS/cm) |
|---|---|---|
| Tap water | 7.63 | 210 |
| River water | 7.52 | 250 |
| Treated wastewater | 7.19 | 510 |
Water was collected on four dates, corresponding with four rounds of behavioral assays, and values shown here are mean values for the four water collection events. Specific conductivity is an index of total dissolved solids.
