Tellus Project

Tellus Border Soils and Tellus Border Drainage Projects:

OCAE Consultants Ltd were the appointed contractor for the Tellus Border Soils Project and the Tellus Border Drainage Project over a seven month period from 2011-2012.

This project involved a soil sampling survey to establish a regional scale geochemical baseline of the soils of the northern region of Ireland which involved the collection of 7,108 soil samples from 3,554 locations across six counties. About 1kg of soil was taken from each site using a hand auger,

The Tellus Border Drainage Project involved sampling at 3520 unique locations, involving 3728 water samples, 3427 sediment samples, 3427 heavy concentrate panned mineral samples and 2432 vegetation samples.

The resulting data from the Tellus Border survey was then integrated with the existing Tellus geochemical data of Northern Ireland by the GSI.

 

The Tellus North Midlands Soils Project

OCAE Consultants Ltd. were the appointed contractor for the Tellus North Midlands Soils Sampling Project in July 2014 in conjunction with the Geological Survey of Ireland. This phase of the project sampled a further 2654 unique sites in the north midlands region of Ireland, including all of counties Roscommon, Longford, Westmeath and parts of counties Mayo, Galway, Kildare, Meath, Offaly & Tipperary. The overall aim was to determine a regional-scale geochemical baseline based upon an ad-hoc grided survey method.

The survey comprises the collection soil samples from two depth intervals at each sample site, as per the sampling procedures and methodologies developed and employed during previous regional geochemical surveys undertaken in both the UK by the British Geological Survey and in Ireland by the Geological Survey of Ireland. It is intended to merge the data acquired through this part of Tellus North Midlands with the existing data sets of Tellus North Midlands, Tellus Border and Tellus in Northern Ireland.

OCAE Consultants Ltd. Were the appointed contractor for The Tellus North Midlands Soils Sampling extension which took place in late 2014. This latest phase of Tellus sampled a further 1619 unique sites in the north eastern midlands region of Ireland, including sections of counties Meath, Dublin, Kildare, Offaly, Laois, Tipperary & Galway. Of the 1619 unique sample sites there are 516 high density Urban Samples (1km x 1km grid squares) to be collected in the Greater Dublin Area.

As with previous Tellus project phases, the overall aim is to determine a regional-scale geochemical baseline from representative soil samples based upon an ad-hoc gridded survey method. (www.tellus.ie)
