yield and order for each REC class, which is influenced by the amount of data (viz. contributing sites)
within each class. The REML model does not produce a coefficient of determination that can be used
to check of the goodness of fit of the model. However, goodness of fit was assessed using the
frequency with which observed yields fall within the mean yield estimated by the model and 95%
confidence interval for a class.

The levels of Toluene and Xylene obtained in the current work are far below ambient
guideline values, and all results fall
results fell into the MfE
‘Excellent’ air quality category. Three of the four
benzene results were within the MfE ‘Acceptable’
category. One result fell within the ‘Good’ category.
The Council also monitors for VOCs around
significant potential sources, such as gas production
stations, as part consent compliance programmes.
Results always fall well within guideline values.

tunnels, where the water flows from the river into the canal. It is likely that flow velocities through the tunnels
are the primary influence on fish passage, although during low lake levels, water will fall into the intake, which
smaller fish will struggle to negotiate.
Previous survey data show that smelt and torrentfish have been recorded upstream of the weir, with torrentfish
recorded more frequently, though not in abundance. In addition, the station owner/operator reports observing
