Table 2: Microbiological plating-based results. Values shown represent mean colony counts of eight replicates, which were not significantly (p>0.05) different across the sampling times (Fall, Winter, Spring, & Summer). Plate count agar for total chemoheterotrophic bacteria; ACT = actinomycete agar, for soilborne actinomycetes; SDA = Sabouraud dextrose agar for total molds and yeasts.
