+Sample size (n) equaled 12 for Station 12B and 11 for Stations 1B and RR (January data

missing). Less than values (<) indicate the Lower Reporting Limit (LRL) for the variable. The LRL is a statistically determined limit beyond which chemical concentrations cannot be reliably reported. Statistical analyses were utilized only when mean concentrations were above the analytical lower reporting limits. Missing range values indicate that all measured values during were less than the LRL for that variable.

¶Least squares means (LSM) procedure was applied due unbalanced data set resulting from

missing January data for Stations 1B and RR. The LSM procedure was applied only if the overall ANOVA F test for the treatment was significant. Means followed by different superscripts were significantly different (P # 0.05). Data were rounded to conform to significant digit requirements. Rounding may obscure mean differences.
