Coal & Allied – Hunter Valley Operations<br />
The Carrington EIS states that runoff from undisturbed catchments within the Carrington Pit will be directed<br />
around the mine via contour banks to discharge where possible into natural creeks. The salinity of the runoff<br />
water was predicted to be approximately 615μS/cm. Runoff from rehabilitated lands was predicted to have<br />
higher TSS initially, with levels approaching pre-mining conditions after several years. Carrington Billabong<br />
was reported as dry in <strong>2009</strong> with no TSS samples available.<br />
3.5 GROUNDWATER QUALITY<br />
3.5.1 <strong>Environmental</strong> <strong>Management</strong><br />
<strong>HVO</strong> operated a network of piezometers during <strong>2009</strong>. The results are used to establish and monitor trends in<br />
physical and geochemical parameters of surrounding groundwater tables potentially influenced by mining.<br />
The groundwater monitoring programme at <strong>HVO</strong> measures the quality of groundwater against background<br />
data, EIS predictions and historical trends. Groundwater quality is evaluated through the parameters of pH,<br />
EC, and Standing Water Level (SWL).<br />
The monitoring locations are shown in Figure 42 to Figure 44.<br />
