Water quality overall improvements:
Positive impact-WQ improvement
Information on Water quality overall improvements:
The wetland influences water quality on its own. In addition, barley straw bales were added to ponds in 2012 to prevent algal blooms (and can be assumed to have been successful, since there has been no evidence of the algae since).
Information on Water quality Improvements (N):
The constructed integrated wetland achieved:
- 91% reduction in ammonia concentrations
- 16% reduction in nitrate concentrations
- 6.5% reduction in nitrite concentrations.
The addition of barley straw provided further benefits, reducing ammonia by 55% and nitrate by 38%
Information on Water quality Improvements (e.coli):
The addition of barley straw to the pond/weltand achieved a 99% reduction in e-coli concentrations
Soil quality overall soil improvements:
Information on Soil quality overall soil improvements:
Some erosion control measures were implemented on the floodplain of the River Tolka. These measures may improve soil quality by retaining soils, but no specific information was available.
