Strawberry,
I think they are trying to mislead you. The Cement Factory is proposed to be built on the site of the Koru Koy quarry which is in the Uzumlu valley. The site can be seen from most parts of the valley and the pollution will, potentially, cover an area up to 40 kilometers around the site. The estate agent is probably correct in that Koru Koy is 10km by road (less as the crow flies) from the centre of Uzumlu (6 miles)but it is in the heart of this beautiful valley so Koru Koy, Incikoy, Uzumlu, Cadianda, Niff etc etc etc will be affected by it, not forgetting the dozens of lorries that will be trundling through the valley 24 hrs a day providing the raw materials and taking away the finished produce.
A question not answered yet is where are they going to dump the waste products?
To sum up, they are playing with distances and trying to mislead you, an area 40 kilometers around the factory could be affected. Plus, most of the houses we have seen for sale in Uzumlu have an uninterrupted view of the site.
Best option come and have a look for yourself and then you can make an informed decision.
Hope this helps.
