In October, we visited EPA’s offices in Dublin to meet with members of the Catchment Team, the Groundwater Team, and the Drinking Water Team. In these interviews, we learned about the impact of EU and Irish legislation on the ways that the agency thinks about and helps to manage water resources–both for its ecological health and as a source of drinking water. In these histories, we learned about how and why ‘catchment’ thinking was introduced in Ireland and the what effects of the recast of the Drinking Water Directive will have.
