Table 4.3   Correlation coefficients (r) and probabilities (p) from analyses between fecal
                    coliform bacterial counts, turbidity, and area rainfall in the 24 hr preceding
                    sampling for 11 coastal plain streams, n = 6 months. Also presented is percent
                    of each watershed comprised of wetlands and number of CAO’s per watershed.
                    CAO’s are concentrated animal operations containing more than 500 head of swine.
                    Correlations are statistically significant when p < 0.05.
