    **In the 1930s and going on to the end of the 1940s, houses were built in this area. Lots and lots of houses. Here you can see a picture taken from Google of the houses on Dunraven Road. **As soon as the letters were sent to the residents, the story was broke by the South Wales Echo. It also got national attention. Here you can see a screen shot from the bbc website, with the headline Arsenic in soil warning in city.

And it certainly didnt help the residents what do you think might have been a consequence of this sort of story in relation to the residents? [falling property prices/blight]*********
