+\title{Calculate initial predicted environmental concentrations in surface water due to drainage using the UK method}
+\usage{
+PEC_sw_drainage_UK_ini(rate, interception = 0, Koc,
+  latest_application = NULL, soil_DT50 = NULL)
+}
+\arguments{
+\item{rate}{Application rate in g/ha}
+
+\item{interception}{The fraction of the application rate that does not reach the soil}
+
+\item{Koc}{The sorption coefficient normalised to organic carbon in L/kg}
+}
+\value{
+The predicted concentration in surface water in µg/L
+}
+\description{
+This implements the method specified in the UK data requirements handbook and was checked against the spreadsheet
+published on the CRC website
