observation
bores were also installed within the vicinity of the production bore to monitor the effects of the
abstraction on local groundwater levels. Water levels within two of the observation bores are
monitored electronically by pressure transducers. The pressure transducers are programmed
to record measurements at 30 minute (GND2102) and 15 minute (GND2103) intervals
The Council’s monitoring programme for the period under review included five inspection
visits to the site. Inspection

2.6 of the Odour GPG. Acute
effects arise from short-term (a few minutes to an hour) exposure to
intense and unpleasant odour. However, long-term exposure to lower
levels of even moderately unpleasant odour can also result in a similar level
of adverse effects.
4.45 The same assessment tools can be used to assess both acute and chronic
odour exposure. Duration is included as a factor in a FIDOL assessment,
although I note that there can be practical difficulties in
levels after several minutes, with erratic variability in water levels
during the timed recovery phase. User error and dip failure were ruled out as both BTW Company
technicians corroborated the water level measurements and operation of the electronic dip tape in
a bucket of water. Groundwater levels in GND 2190 fluctuated in the initial three minutes after
'slug' removal but in the next one hour and 14 minutes water levels stabilised but never fully
recovered to initial water level. However, final
of the activities on the site, it was considered that the primary information of interest
in respect of gases potentially emitted from the site was the average downwind concentration, rather than
any instantaneous peak value. That is, the long-term exposure levels, rather than short-term maxima, are of
most interest. The gas meter was therefore set up to create a data set based on recording the average
concentration measured during each minute as raw data.
