Deeper Water Dumping Might Be Solution To Dublin Bay Dredging Issues Says Diver

#DublinBay - The dumping of sewage sludge in deeper waters beyond the Kish Bank “might well serve as a model” for the current dredging of Dublin Port.

In a letter to The Irish Times earlier this week, Cormac F Lowth, a diver and member of the Maritime Institute of Ireland, responds to the claims of Dublin Port Company’s chief regarding the effects of recent dredging operations.

Dublin Port CEO Eamonn O’Reilly defended the dredging operations in the port, citing “the science available to measure its impact” in response to discontent among diving groups over the state of the water in Dublin Bay.

Divers concerned that the dredging is to blame for murky waters, which have seen all planned dives cancelled due to poor visibility, have however “ignored the obvious” and might now look further east for a potential answer to a question that’s left the bay’s crabs and lobsters with ‘an overcoat of silt on their backs’.

Lowth explains that dredging spoil such as that dumped at the Burford Bank at the edge of Dublin Bay contains estuarine mud and fluvial silt that “is not going to remain in toto on the top of this bank”.

“A glance at a tidal atlas for Dublin Bay is enough to convince one that much of anything that gets dumped near the mouth of the bay will get washed back in by the strong tidal currents,” writes Lowth. “This can surely be described as the maritime equivalent of defecating on your own doorstep.”

The Irish Times has more on the story HERE.
