This is a good point, Al. It is one that Lafarge have mentioned.
The intention is to establish whether it is physically possible to monitor the air at ground level in places where the cement works plume is known to ground, such as the eastern end of Studland Park / The Butts / upper Newtown.
The chief Environmental Health Officer at WWDC advised me that this would have two stages. The first is establishing what type of monitoring is possible, installing the machine and running it to collect data over a long enough period. The second is analysing the data to establish what any data means and whether it poses any health risk.
The PCT and HPA would have to be involved in determining whether this was a public health risk to people in the area.
To my mind, if the results of all of this showed that there is a pollution issue, we would then have to turn to looking at the possible sources of the pollutant. At that stage, I think all options would have to be looked at to nail down the exact source, but by then we would have identified a more specific problem to look for.
Clearly, if the results of any extra monitoring show that there is no increased risk to health, then the exercise would help allay any fears people in the locality have, especially if this is tied in with any statistical evidence that there are no statistical blips in the area reflecting above-average diseases etc.
