1. Climate

• 800-2000mm of rain per year spread across the year

• Mild temperatures so not locked up as ice or quickly evaporates

• Groundwater recharge twice that of the south of England

3. Policy

Groundwater Quantity• The Water Abstraction and Impoundment

(Licensing) (Amendment) Regulations (Northern Ireland) 2007 – Protect investments.

• No active restrictions on licensees

Open for Business!

3. Policy

Groundwater Quality• Agriculture – Nitrate Action Plans

• Industry – Pollution Prevention Control Permits

Groundwater Quality will not Deteriorate

4. Baseline Conditions

Groundwater Quantity• Aquifers are full

• Far higher recharge rates than previously estimated

4. Baseline Conditions

Groundwater Quality• Exceeds Drinking Water Standards – Little or no

treatment required
