Assessment Purpose

This assessment has been produced as part of the national characterisation programme undertaken for the second cycle of Water Framework Directive river basin management planning. It has been led by the EPA, with input from Local Authorities and other public bodies, and with support from RPS consultants.

The characterisation assessments are automatically generated from the information stored in the WFD Application. They are based on information available to the end of 2015 but may be subject to change until the final 2018-21 river basin management plan is published. Users should ensure that they have the most up to date information by downloading the latest assessment before use.

2 Evaluation of PrioritySubcatchment Issues

Smartcastle Stream_020 is the only water body that is At Risk in the subcatchment and is due to moderate biological status in both 2010-2012 and 2014 (due to biology and total oxidised nitrogen). Total oxidised nitrogen concentrations range from 3-4 mg/l across the entire subcatchment monitored with no discernible biological impact elsewhere. Phosphate and ammonia concentrations are at high status but nutrients may still be the issue as they may be taken up by algal growth. There are pockets of the area that have high pollution impact potential for phosphate to surface water along the channel and headwaters. Diffuse agriculture and farmyards may also be significant pressures. Loadings for phosphate are estimated as Pasture 61%, Arable 11%, Forestry 16% and Domestic Wastewater Treatment Systems 11%.

The landfill in this water body is not considered to be a significant pressure as Co. Co. has undertaken risk assessments on it. The Wastewater Treatment Plant was upgraded to tertiary treatment in 2014 and biological status has improved from Moderate to Good Status in Blackwater (Kilmacow)_040.
