Count beach exceedances for enterococcus

Usage

anlz_entpep(entdat, thr = 104)

Arguments

entdat: result returned from read_pepent
thr: numeric value defining threshold for exceedance

Value

A data.frame with counts of exceedances per year for each beach

Details

The exceedance threshold is set by default as 104 cfu/100 ml criterion. This is simply based on counts in a year when any value at any station was above the threshold for each 24 hour period in the record.

The samples column shows how many days of the year were sampled at each beach and the exceedances column shows how many samples were above the threshold.
