On the second day of our trip in late October to Co. Roscommon, we spent the day with Noel Carroll, the manager of the Mid-Roscommon GWS. We followed his car as he showed us the treatment plants and two sources for the GWS. We returned to some of the same sites we had visited on the IAH fieldtrip earlier in the month, but came away with new observations and understandings, particularly at Ogulla Spring. The water had improved in quality in part because we visited on a day following several without rain. Ogualla Spring is also a holy well, and while we visited we learned more about the significance of holy wells as a source of cures that attracts many visitors every year. Throughout the day, Noel also demonstrated many of the technologies that the scheme utilizes in its day-to-day activities.
