+
+    Make na.rm = FALSE the default for geomean()
+    
+    This makes more sense and is in line with mean() from base R. Adapt
+    tests and update docs.

+#' Estimation of the transpiration stream concentration factor
+#'
+#' The FOCUS groundwater guidance (FOCUS 2014, p. 41) states that a reliable measured
+#' log Kow for neutral pH must be available in order to apply the Briggs
+#' equation. It is not clarified when it can be regarded reliable, but the
+#' equation is stated to be produced for non-ionic compounds, suggesting that
+#' the compound should not be ionogenic (weak acid/base)
+#' or ionic.
+#'
+#' The Dettenmaier equation is given to show that other views on the subject exist.
