|
CS2 Control Station 2 [Easting:838237 Northing:818804] |
|
CS3 Control Station 3 [Easting:839105 Northing:819019] |
(2) Action and Limit Level for:
|
Action level: 4.03mg/L for Surface & Middle; 3.94mg/L for bottom. |
|
Limit level: 3.88mg/L for Surface & Middle; 2.00mg/L for bottom. |
|
Action level: 13.80mg/L or 120% of upstream control station's SS at the same tide of the same day |
|
Limit level: 18.70mg/L or 130% of upstream control station's SS at the same tide of the same day |
|
Action level: 7.00NTU or 120% of upstream control station's Turbidity at the same tide of the same day |
|
Limit level: 8.40NTU or 130% of upstream control station's Turbidity at the same tide of the same day |
|
Action level: 2.00µg/L or 120% of upstream control station's nutrient level at the same tide of the same day |
|
Lmit level: 3.00µg/L or 130% of upstream control station's nutrient level at the same tide of the same day or whichever is the less |
|
Action level: 1.60µg/L or 120% of upstream control station's nutrient level at the same tide of the same day |
|
Limit level: 1.60µg/L or 130% of upstream control station's nutrient level at the same tide of the same day or whichever is the less |
(3) For DO, non-compliance of the water quality limits occurs when monitoring result is lower than the limits. For turbidity, SS, Copper and Total PAH, non-compliance of the water quality limits occurs when monitoring result is higher than the limits.
(4) In accordance with Section 7.9 of the EM&A Manual, the detection limits for copper and Total PAH are 1.00µg/L and 1.60µg/L (0.1 µg/L of individual PAHs) respectively. |
