River Boyne Water Quality Management Plan - EPA

Rivcr Boync \Vater Quality Managrmmt Plan5.3 Pl~ysico-cl~emical AssessmentRegular sampling is carried out in the Boyne River System for a range of physico-chemicalparameters by the local authorities in association with EPA. Appendix 3 of the Technical Datacontains summary Tables of water quality data for catchment rivers. The sampling locations on eachriver are tabulated, together with the EPA reference number, where relevant.This sampling programme provides a water quality database from which the following can beestablished:The parameter values in the water column which can be used to monitorpollution levelsbased on guidelittle values, for example, the limits in the relevant E. (I. directives andassociared National Regi~[ations.Trends can be evaluated over time and by river reach.Physico-chemical data is particzrlarly useful to trace pollirtion incidents to ozr~alIs andprimary sources.The eflects of discharge loads can be assessed, relative to baseline valtces and guidelinelimits, by sampling zrpstrea~n mtd downstream of dischar@?This ongoing monitoring progranme requires the im&&&ation of an environmental databasemanagement system which would allow for data $&&', analysis, trending and reporting.
