Testing just above the confluence. The conductivity of the unaffected stream was 391.1 μS/cm, while the conductivity of the impacted stream was 1016 μS/cm. The pH was very similar in both, and within normal range. Collected grab samples for metals, total suspended solids, and volatile organic compound analysis.
