Plenty of blame to go around here - - looks like Galway and Mayo County Councils share some. I’m sure @PickyPicky will be excoriating them in future.
"Tuam
9.In the light of a great deal of inaccurate commentary about the Tuam site, the Commission considers it important to emphasise what it has established and what it has not established.The memorial garden site contains human remains which date from the period ofthe operation of the Tuam Children’s Home so it is likely that a large number of the children who died in the Tuam Home are buried there.The human remains found by the Commission are not in a sewage tank but in a second structure with 20 chambers which was built within the decommissioned large sewage tank.The precise purpose of the chamber structure has not been established but it is likely to be related to the treatment/containment of sewage and/or waste water. It has not been established if it was ever used for this purpose although soil analysis illustrates that it is likely it was so used for an unspecified duration. The Commission does not consider that any of its features suggest that it was deliberately formed as a crypt or formal burial chamber. If that were the case, an entirely different type of structure would have been expected that would allow for easy human access. It has not been established that all the children who died in the Tuam Children’s Home are buried in this chamber structure. There is some evidence that there may be burials in other parts of what were the grounds of the Home.
10.It seems clear that relatively extensive work and construction was conducted in around the site of the Children’s Home in Tuam, particularly during the July –December 1937 period. The Commission thinks it possible that the reworking of the old sewage tank and the construction of the second structure described above may and have occurred at this time. If this is so, then the human remains found in the chambers are likely to date from after 1937. This raises the question of where the children who died before then are buried.
