The Brett Aggregate planning application will not be going to committee this month – September.
It’s time for a Country Park not a quarry!
We’re fighting plans to turn Hatfield’s Ellenbrook Fields into a
quarry. There are major concerns about an enormous bromate plume (a known
public health risk!) lying just metres away from the proposed digging site
which could have a devastating impact on all of our drinking water! Help us
help Hatfield and share this now. You were promised that this would become a
Country park 20 years ago, the landowners have not yet done this, now a quarry
for 32+ years, will it ever be our Country Park?

The latest from Brett Aggregate is a map and chart:

The chart shows borehole data from the contaminated N.E. corner of the quarry site. The lagoons will be dug out from this sector, extremely close by to BH 201 and BHB, which shows signs of bromate contamination.
BH108 appears to be dry, yet it reaches 21m in depth. The chalk shows high levels of bromate bro3, average 232 for 2018 and 227 for Feb 2019. It is situated in a cage and no recent samples have been taken. It is just 163m from the N.E. corner.
The general sample policy is to take four samples in a year period. From the general ground features, it appears that this is not the case. One sample was taken in February and we are nearly 9 months into 2019.
February is normally the driest period and an accurate mapping of contamination cannot be made.

“Bromate concentrations at many locations show a seasonal variation, typically
being higher during summer months and low during winter month although the
relative timing of the peak varies spatially and may reflect the spatial distribution
and movement of recharge and its impact on water levels throughout the aquifer”.
