Near Surface Nitrate Susceptibility

This dataset shows Near Surface Nitrate Susceptibility. Pollution Impact Potential (PIP) maps were generated separately for nitrate and phosphate to rank critical source areas (CSAs) relative to one another from diffuse agriculture for both the groundwater and surface water receptor. The PIP maps are generated by the EPA Catchment Characterisation Tool (CCT). The CCT delineates the CSAs displayed in the PIP maps by overlaying the hydro(geo)logically susceptible areas (the likelihood of nutrient transfer due to soil and geological properties along the near surface and/or subsurface pathway) with nitrate or phosphate loadings. The nitrate and phosphate PIP maps for the surface water receptor combine the contribution from both the subsurface pathway and the near surface pathway while the groundwater receptor maps only consider the contribution from the groundwater pathway.

Surface Water Receptor Nitrate PIP map shows the relative pollution impact potential to surface water along the subsurface and near surface pathways due to nitrate loading. This map should be used to evaluate nutrient impact at the waterbody, subcatchment or catchment scale (at a resolution of less than 1:20,000).

Pollution impact potential (PIP) maps rank the CSAs in descending order of risk (where Rank 1 is the highest risk) and are available for the surface water receptor for nitrate and phosphate, and the groundwater receptor for nitrate. Local pressure data has been used to generate the maps in agricultural areas where available. For urban, forestry and the remaining agricultural areas, regional sources of pressure data have been used; these areas are marked 'using regional loadings' on the PIP maps.

Purpose

The Pollution Impact Potential (PIP) Maps are designed to rank critical sources areas relative to one another in order to inform where further investigative assessment should be targeted to identify sources of diffuse agricultural at the subcatchment scale.

Statement

Details of methodology used are given in the documents in the Online Resources. CCT Factors and input data developed during the Pathways Project were used as input to this project. The other main sources of input data for this project include the latest WFD river waterbody sub-basins, the corine landcover 2012 dataset (EPA) at a scale of 1:100,000, Agricultural statistics broken down by district electoral division (DED) from the Census of Agriculture 2010 (CSO 2010), Soil classification and natural soil drainage map from EPA / Teagasc at a scale of 1:50,000. A number of GSI input datasets were used - Depth to bedrock map, National recharge map (1:50,000) Subsoil permeability (K) map (1:40,000), Potential bedrock denitrification map and Aquifer bedrock boundaries (1:100,000), land Parcel Identification System spatial data and Nitrate per Hectare data (Department of Agriculture, Food and the Marine, 2012)
