ENVIRONMENTAL DATA ANALYSIS

Ambient Air Quality

The ambient air quality with respect to the study zone of 10 km radius around the

existing Power plant forms the baseline information. All the sampling locations fall

within 10 km radial distance from the existing Power plant.

To assess the effect of power plant activities on the air, the following 12 parameters

are considered for analysis

1. Particulate Matter (PM10) – size ˂10 µm or PM10 µg/m3

2. Particulate Matter (PM2.5) – size ˂2.5 µm or PM2.5 µg/m3

3. Sulfur Dioxide (SO2)

4. Oxides of Nitrogen (NOx)

5. Ozone (O3)

6. Ammonia (NH3)

7. Lead (Pb)

8. Arsenic (As)

9. Nickel (Ni)

10. Carbon Monoxide (CO)

11. Benzene (C6H6)

12. Benzo(α)Pyrene (BαP)

The results of monitoring carried out for study period (APRIL, 2015 – SEPTEMBER,

2015) are presented. The details of the sampling locations with respect to the Power

Plant are given below in the table.

Observations & Summary:

1. The source of raw water is river Krishna and the parameters (17 parameters) are all within the acceptable range.

1. The pH in the range of 6.5 – 8.5 is ideal.

2. The suspended solids and total dissolved solids are far less than the desirable range.

3. The presence of metals and oil & grease is below detectable limits.

4. The presence of hardness, sulfates and chlorides is very less making it fit for industrial use.

5. The COD is in range of 20 - 42 mg/L and BOD <20 mg/L against the limiting standard 250 mg/L and 100 mg/L respectively

2. The wastewater normally generated as blowdown from Cooling Tower and Boiler and reject water from RO plant.

1. The pH of effluent from blowdown is in permissible range of 6.5 – 8.5.

2. The TDS from CT blowdown is between 1200 – 1900 mg/L and from DM plant in the range of 1200 – 1500 mg/L. The

limiting standard as per CFO consent for TDS is 2100 mg/L.

3. The metals such as Iron in the between 0.10 – 0.2 against standard of 1.0mg/L, Chromium in the between 0.10 – 0.16 against

standard of 0.20 mg/L and Zinc in the between 0.06 – 0.14 m/L in blowdown against limiting standard 1.0 mg/L.

4. Oil & grease is found to be between 1.2 and 1.8 in CT blowdown and BDL in waste water generated from DM plant against

limiting standard of 10 mg/L.

5. The COD found to be in between 100 to 180 as against 250 mg/L and BOD between 34 to 64 mg/L against 100 mg/L

limiting standard.
