-- removal of riparian vegetation
+The proposed dairy processing facility is supposed to be located close
+to the river for easy access to water and for the convenient discharge
+of waste water back into the river.  The preparation of the site for
+construction in proximity to the river as well as the proposed take
+and discharge activities during operation of the factory have direct
+effects on water quality parameters. Changes to the properties of the
+body of water (e.g. sediment load, changes in flow patterns, increases
+in nutrient levels) affect not merely aesthetical values of residents,
+but are likely to have impacts on the composition of aquatic
+communities and the health of riparian and aquatic ecosystems.
 
-\subsection{Expected impacts during operation}
+\subsubsection{Construction}
 
+Preparing the selected site for construction requires the displacement
+of existing uses. On a site close to the river in a rural area, the
+site may be populated by riparian vegetation. Vegetation in the
+riparian area and the adjoining uplands may serve as a filter,
+reducing the amount of sediment, excess nutrients and other pollutants
+entering the river \parencite{riparian}. This filtering ability is
+particularly valuable in a region where dairy farming is expanding and
+with it the cumulative impact of non-point sources of farm effluent is
+increasing.
