Water quality in Ireland 2006 - ups and downs

The Environmental Protection Agency has launched its 66 page 'Water quality in Ireland 2006 - Key Indicators of the Aquatic Environment' report.

Having monitored Ireland's surface and ground waters between 2004 and 2006, it shows "an improvement in river and lake water quality, but poorer quality in some groundwaters". Findings included that:
  • River channel: 71% was of satisfactory water quality.
  • Lake surface: 92% was of satisfactory water quality.
  • Estuarine/coastal water bodies: 19% were eutrophic; 3% were potentially eutrophic.
  • Groundwater samples: 57% contaminated by faecal coliforms; 25% exceeded the national guideline value for nitrate concentration for drinking water, and 2% breached the mandatory limit.
  • Fish kills: fewer than in 2005, but still unreasonably high.

The island of ireland

Once upon a time, and for 15000 years, ice a mile high blanketed Ireland. When the lingering Ice Age finally released and the Irish ice departed it left a landscape scoured. Across land bridges linking Ireland, Britain and mainland Europe plants and animals arrived to colonise the new lowlands, mountains and valleys. The world’s ice continued to melt, the sea levels to rise, and some 8000 years ago Ireland became the island we now know, accounting for just 0.01% of the world's total land area and the most westerly point of Europe.

Though at Alaskan latitudes, the country's climate is tempered, due partly to the neighbouring waters of the Gulf Stream and partly the prevailing southwesterlies that veering and backing make landfall on our sodden coast. These offerings from the Atlantic mean it is never too hot, never too cold. But without doubt it is wet. Rain lingers year round, never far away, though is most frequent in winter, the western counties and, inevitably, on the day of your parade.
