Abstract
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 Phosphate PIP maps show the relative the pollution impact potential to surface water along the subsurface and near surface pathways due to phosphate loading. This map should be used to evaluate nutrient impact at the waterbody, subcatchment and 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 agriculture at the subcatchment scale.

Use limitation
The Pollution Impact Potential maps are not publicly available, they can only be accessed by public bodies through the EPA WFD App on the EDEN portal. Information supplied is based on the material available in the EPA at the time of production and should not be regarded as complete data on the elements or areas being considered. Uncertainty is an inherent element in drawing (hydro)geological boundaries and local details are generalised to fit the original mapping and interpretation scale of 1:40,000 or lower. Additionally the main source of nutrient loadings data is derived from the Land Parcel Identification System (LPIS) supplied by DAFM. Where there is no LPIS data available, including all urban areas, the nutrient loadings are derived from Census data provided by the Central Statistics Office for each District Electoral Division. For forestry and wetland areas, atmospheric deposition is assumed the only nutrient input. These maps should not be used in isolation as they have been developed as a first step to inform where additional investigative assessment is required. The maps are not intended to be viewed at a resolution higher than 1:20,000. It is intended that statutory authorities should apply the maps to inform decision-making on the basis that the best available data are being used.

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)
