1. As per order dated 07.06.2021, this Tribunal had considered the report submitted by the Andhra Pradesh Pollution Control Board dated Nil e-
filed on 19.02.2021 extracted in Para 4 of the order and also considered the discussion of water quality and conclusions given therein in Para 6 & 7 of the order and then, passed the following order:-
"8. It is seen from the conclusion portion that in order to avoid pollution to the water body, certain steps will have to be taken and those will be completed by October, 2021. Further, it is seen from the water quality that it is neither covering large area nor the disputed area in respect of which allegations have been made. It is also not known whether water from all major drains leading to the reservoir have been tested or not. They have not mentioned anything about the E Coli or total coliform in the water quality. They have also not reported about the pollution loads in the sediments. They have also mentioned about the approx extract of the estimate for carrying out the recommendations. It is seen from the report that BOD value is found to be less than 2ml/g per litre. It is also 13 mentioned that bio-assay test indicates that the water needs to be treated before it is used for drinking water purposes that shows that quality of the water is not suitable for drinking and if this water is used for drinking purposes then it will have great impact on the health of the people.
9. When this was pointed out the Learned Counsel appearing for the State of Andhra Pradesh and Pollution Control Board submitted that they will come with fresh report regarding the nature of action taken by the Visakhapatnam Municipal Corporation regarding Solid Waste Management Rules, 2016 and also the implementation of the directions given by the Principal Bench in several cases mentioned above and the action taken by the Pollution Control Board if directions of the Principal Bench are not implemented as directed by Principal Bench in those cases.
10. The Greater Visakhapatnam Municipal Corporation and Pollution Control Board are directed to come with fresh detailed report covering all the aspects detailed in para 5 to 9 and whether on account of the measures taken, the water quality in the Lake has been improved to the extent of drinking water purposes, as it appears from the reports that this water is used for drinking water purposes as well. They are directed to submit the respective report before this Tribunal on or before 28.07.2021 by e-filling in the form of searchable PDF/OCR supportable PDF and not in the form of image PDF along with necessary hardcopies to be produced as per Rules.
11. The Registry is directed to communicate this order to the official respondents by e-mail immediately so as to enable them to comply with the directions disused by this Tribunal."

As per the analysis of the samples, it is observed that the physico chemical parameters and heavy metals are within the prescribed standards of drinking water as per IS 10500 : 2012. Presence of Pesticides is not detected. It is common phenomenon to find total coliforms in reservoirs storing surface water. All municipalities employ disinfection through chlorination to eliminate coliforms and also pathogens if any in the drinking water before supplying to public. Hence the water of Megadrigedda Reservoir is fit for drinking purpose after disinfection. The analysis also indicates no contribution of industrial wastewater.
Drain water quality APPCB collected samples from the inlet drains joining the reservoir and analyzed for physico chemical (16 parameters), Bacteriological (2 parameters), heavy metals (10 parameters) and pesticides (17 parameters). As per the analysis, all the physico chemical parameters and heavy metals are within the prescribed standards of drinking water as per IS 10500 : 2012. Presence of Pesticides is not detected. BOD (4.2 mg/l to 4.8 mg/l) and total coli forms (64 to 93 MPN) are slightly exceeding the drinking water standards. This may be due sewage contamination from residential areas of Pendurthi, GVMC limits. Sediment Quality Sediment samples (7 No.s) from drinking water reservoir and from the inlet drains joining the reservoir were collected and analyzed for heavy metals such as Chromium (8.75 to 13.14 mg/kg ), Nickel (2.76 to 9.78 mg/kg), Copper (3.58 to 14.63 mg/kg), Zinc (6.55 to 86.08 mg/kg), Arsenic ( 0.29 to 1.06 mg/kg) , Cadmium (0.03 to 0.26 mg/kg), Lead (3.40 to 8.39 mg/kg), Mercury (0.02 to 0.04 mg/kg). The concentrations of all the metals analysed in the sediments samples are below USEPA sediment standards and Threshold Effect concentration (below which adverse effects are not expected to occur) as per consensus based Sediment Quality Guidelines (SQG) enclosed as (Annexure II).

As per the analysis of the samples, it is observed that the physico chemical parameters and heavy metals are within the prescribed standards of drinking water as per IS 10500 : 2012. Presence of Pesticides is not detected. It is common phenomenon to find total coliforms in reservoirs storing surface water. All municipalities employ disinfection through chlorination to eliminate coliforms and also pathogens if any in the drinking water before supplying to public. Hence the water of Raiwada Reservoir is fit for drinking purpose after disinfection. The analysis also indicates no contribution of industrial wastewater.

Presence of Pesticides is not detected. It is common phenomenon to find total coli forms in reservoirs storing surface water. All municipalities employ disinfection through chlorination to eliminate coliforms and also pathogens if any in the drinking water before supplying to public. Hence the water of Gambhiramgedda Reservior is fit for drinking purpose after disinfection. The analysis also indicates no contribution of industrial wastewater.
Drain Water Quality APPCB collected sample from the inlet drain of Gambhiramgedda reservoir and analyzed for physico chemical (16 parameters), Bacteriological (2 parameters), heavy metals (10 parameters) and pesticides (17 parameters). As per the analysis, it is observed that all the physico chemical parameters and heavy metals are within the prescribed standards of drinking water as per IS 10500: 2012. Presence of Pesticides is not detected. It is common phenomenon to find total coli forms in surface water drains. The analysis also indicates no contributionof industrial wastewater.
Sediment Quality Sediment samples (4 No.s) from drinking water reservoir and from the inlet drain joining the reservoir were collected and analyzed for heavy metals such as Chromium (10.58 to 16.96 mg/kg ), Nickel (7.89 to 16.63 mg/kg), Copper (9.46 to 21.15 mg/kg), Zinc (15.48 to 33.91 mg/kg), Arsenic ( 0.6 to 1.71 mg/kg) , Cadmium (BDL to 0.08 mg/kg), Lead (8.05 to 12.14 mg/kg), Mercury (0.01 to 0.03 mg/kg). The concentrations of all the metals analysed in the sediments samples are below USEPA sediment standards and Threshold Effect concentration (below which adverse effects are not expected to occur) as per consensus based SQG enclosed as (Annexure II).
Conclusions on water quality of reservoirs :
Water quality is meeting all the physico - chemical, heavy metals and pesticides parameters except presence of coliforms as per IS 10500 standards of drinking water. However, water is fit for drinking after disinfection.
BOD is observed in the inlet drains of Meghadrigedda and Mudasarlova which may be due to sewage contamination.
The sediment quality in all reservoirs are below the USEPA sediment standards and Threshold Effect concentration (below which adverse effects are not expected to occur) as per consensus based SQG.
The above report is placed before the Hon'ble Tribunal for its kind consideration to pass appropriate directions."
5. It is mentioned in the report that the water quality in the reservoir though consist of Faecal Coliform, it is fit for drinking after disinfection.
The BOD is observed in the inlet drains of Meghadrigedda and Mudsarlova which may be due to sewage contamination and the sediment quality in all the reservoirs are below the USEPA sediment standards and Threshold Effect concentration (below which adverse effects are not expected to occur). It is not known whether samples have been collected from the same locations reported in the study on the basis of which it is alleged that the reservoirs are polluted.
However, there is nothing mentioned about the reason for cause of health issue projected in the newspaper report. They have only submitted that a Joint Committee was appointed under the leadership of the Chief Secretary and they will take further action on the basis of the same.
6. When this was pointed out, the learned counsel appearing for the State of Andhra Pradesh submitted that they will come with a further detailed statement in this regard.
7. The learned counsel also submitted that a writ petition is still pending before the Hon'ble High Court of Andhra Pradesh as W.P. (PIL) No.248 of 2020.
8. They are directed to file details regarding the directions (if any) given by the Hon'ble High Court of Andhra Pradesh in this regard.
9. They are also directed to submit the further reports as directed on or before 17.08.2021 by e-filing in the form of Searchable PDF/ OCR Supportable PDF and not in the form of Image PDF along with necessary hardcopies to be produced as per Rules without fail.
10. The Registry is directed to communicate this order to the official respondents including Chief Secretary, State of Andhra Pradesh by e-
mail immediately for their information and also compliance with the direction.
11. For consideration of further reports, post on 17.08.2021.
