Surface water FC concentration tended to vary seasonally,
with 75% of sites having significantly different mean FC concentrations
among seasons (Table S2). However, evidence for
hydro-meteorological variability driving seasonal FC concentration
variability was only observed among half of these sites
(Table 1). The proportion of sites that showed evidence of
climate forcing varied among hydro-meteorological regimes,
as did the season in which peak FC concentration occurred.
The majority of the 27 sites with nival hydrometeorological
regimes experienced peak FC concentration
during summer (59%; 16 sites), a minority during spring (15%;
four sites), and a single anomalous site in winter (4%). Seasonal
FC concentration variability was significantly related to
hydro-meteorological variability for around half of these sites
(56%, or nine, and 50%, or two, of the sites with peak fecal
contamination in summer and spring, respectively).
