A stream (0.21 m3/sec) emerges from a mine adit and flows into a larger watercourse. Due to acidic main drainage, the pH of the tiny creek is 1.9, whereas the pH of the larger creek is 6.7. (above the adit-stream confluence). Water travels 7.5 minutes to reach a monitoring station that is situated 450 meters downstream of the confluence. At the monitoring station, the creek's cross-sectional area is 3.5 m2. What pH level would you anticipate at the monitoring station?
