Man-made Features
A
list of pits and quarries within the study area are given
in Table 2 of Appendix A. The location of the main quarries
and pits in the constraints study area are shown on Figures
5A and 5B. At this stage no major landfill areas have been
identified in the constraints study area. However the search
was not exhaustive as it was based on limited historical data.
The GSI are presently updating their records of pits and quarries.
It is anticipated that updated records will be available in
May 2001.
7.6.1
Pits
The geotechnical constraints mapping (Figures 5A & 5B) shows
many gravel pits, both in-use and disused, within the gravel
strata that occur within the constraints study area.
7.6.2
Quarries
The
locations of quarries prove a good way of verifying locations
where the rock is close to the surface. There are many quarries,
mostly disused, noted in the southern portion of the southern
section of the constraints study area, north of Waterford
City. Anecdotal evidence also suggests that an in-filled landfill
site exists to the north of Bennetsbridge.
7.6.3
Landfills
A list of landfill sites compiled by the Environmental Protection
Agency (National Waste Database 1998) was consulted for identifying
any landfill sites occurring within the constraints study
area. Based on the EPA list there are no major landfill sites
within the constraints study area. According to the GSI data
there appears to be an old landfill located just north of
Waterford City.
