EXECUTIVE SUMMARY
ERM India Private Limited (ERM) was commissioned by the Telangana State
Pollution Control Board (hereinafter referred to as ‘TSPCB’ or the ‘Client’) for
providing consultancy services for the Assessment of Contamination, Design of
Remediation Plan and Supervision of Remediation Activities of Kazipally
Tank (hereinafter referred to as the ‘Project’) situated in Sangareddy District,
Telangana, India (hereinafter referred to as ‘Kazipally Lake’).
This Report presents findings from the Task 1 – Reconnaissance and Preliminary
Assessment of the lake and its catchment area. The field activities for Task -1 were
initiated on 4 July 2016 and were completed on 29 July 2016.
Scope of Work of Reconnaissance and Preliminary Site Assessment
Background Literature Study and Collation Visual Inspection Site Reconnaissance Drainage Survey Receptor Survey Stakeholder Consultation Inventory of Potential Contaminant Sources
The Kazipally Lake is located in Kazipally village, situated 35 km towards the north- west of Hyderabad, in the Jinnaram Mandal of Medak district, in the southern state of Telangana. The drainage area of Kazhipally Lake lies in the Nakavegu watershed, which is part of the Manjeera sub-basin of the Godavari River. The total area of the
lake is approximately 32 acres (~ 1,20,500 m2), out of which wet lake area is around 7. 5 acres (30,351 m2) as per the Survey of India Toposheet number 56 K/6 on 1:50,000
scale, published in year 1974.
Current Site Condition
During the time of the field visit it was noted that, water cover is restricted to small
pockets of the Kazipally Lake, and small channels were observed to be flowing into
these pockets within the lake bed. Water was observed to be flowing out of the lake
through a weir, towards the southwest side, across the lake bund. The water was
observed to be black in colour, with chemical odour in some parts of the lake area.
Patches of red and yellow colour was observed on the exposed lake bed at various
locations.
Drainage Survey
During the survey of the drainage patterns across the watershed, ERM team noted
that the Jillala Vagu, which is a natural stream, carries water from the north-western
portion (industrial cluster) of the watershed to the Kazipally lake; and Lotha Vagu, a
stream flowing from the north-eastern portion of the watershed carries water through
the forest areas and TSDF area to the Kazipally Lake. The water in both streams was
observed to be dark black in colour, with chemical odour.
The Telangana State Pollution Control Board (TSPCB) is a statutory
organisation responsible for the implementation of environmental laws and
rules within the jurisdiction of the State of Telangana, India. Capacity
Building for Industrial Pollution Management Project (CBIPMP) is a project being implemented by the Ministry of Environment, Forest & Climate Change, Government of India with the assistance of the World Bank. TSPCB is
designated as the special purpose vehicle for the implementation of the project in the Telangana State.
The CBIPMP was rolled out to build the environmental management capacity
of environmental institutions including state regulatory bodies and to
promote investments in integrated pollution management.
1.3 PROJECT OBJECTIVES
The objective of the project is to:
To characterize the nature and extent of environmental impact of the lake
body (surface water and sediment), if any;
To characterize the nature and extent of environmental impact, if any, of soil and groundwater from the upstream sources within the lake
catchment area;
To develop of feasible and cost-effective intervention measure(s) to
mitigate the assessed impact(s) of Soil and/ or groundwater and/ or
sediment and/ or Surface water for defined end use;
To prepare the bidding documents for implementation of remedial intervention measures; and
To supervise the implementation of remedial intervention measures.
The objectives are to be achieved in the following steps:
Task 1 - Reconnaissance and Preliminary Site Assessment
o Background Literature Study and Collation o Visual Inspection
o Site Reconnaissance o Drainage Survey o Stakeholder Consultation o Receptor Survey o Inventory of Potential Contaminant Sources
Task 2 - Preliminary Investigation of the Lake
o Topographic Survey o Geotechnical Profiling o Hydrogeological Assessment o Bathymetric Survey o Environmental Screening and Sampling o Develop Preliminary Conceptual Site Model & Qualitative Assessment
o Additional Investigations o Hydrogeological Investigation & Modelling o Risk Assessment o Environmental, Social and Ecological Survey
Task 4 - Developing Remedial Action Plan
Task 5 - Preparation of Detailed Project Report
This Report details the work carried out under Task 1 (Reconnaissance &
Preliminary Site Assessment).
2 SITE RECONNAISSANCE
This Section presents findings from the Desktop Study and Site
Reconnaissance for the Kazipally Lake.
2.1 INFORMATION SOURCE(S)
In order to collect the related information for the project the important stakeholder departments were enlisted with the assistance of the TSPCB. Further, TSPCB also shared the earlier reports with the list of the industries
that are in operation. In addition to detailed Site walk through and interviews
with local people, the various Government agencies approached and
information received from them are mentioned in Table 2.1 below.

2.2 SITE LOCATION
The Kazipally Lake is located in Kazipally village, situated 35 km towards the
north-west of Hyderabad, in the Jinnaram Mandal of Sangareddy district, in
the southern state of Telangana. The drainage area of Kazhipally Lake lies in
the Nakavegu watershed, which is part of the Manjeera sub-basin of the
Godavari River. The total area of the lake is approximately 32 acres (~ 1,20,500
m2), out of which wet lake area is around 7. 5 acres (30,351 m2) as per the
Survey of India Toposheet number 56 K/6 on 1:50,000 scale, published in year
1974.
Refer to Annex A for the Site Location Map.
The Kazipally Lake is located downstream of Gaddapotaram and Kazipally
industrial estates, which were established in the 1980s and comprise of different types of manufacturing units (pharmaceutical, agrochemical, rubber
chemical and bulk drug). Based on available information, it is understood that majority of the companies are involved in bulk drug manufacturing for
pharmaceutical industry. Reportedly, most of these industries are Zero Liquid
Discharge (ZLD) industries since 2011.
The Gaddapotaram and Kazipally industrial estates located upstream of the
catchment area are operational since 1980s, and are located at an aerial
The entire micro-watershed in which the Lake is located is considered as the Study area. The Study area (7.5 km2) is located between 17⁰34’35”N, 78⁰ 21’5”E in the west and 17⁰34’54”N, 78⁰23’56” E in the east, and is split between the Sangareddy (65%) and Medchal (35%) districts, Telangana, India,
and falls in Survey of India Toposheet number 56 K/6.

Based on the data obtained from Groundwater Brochure Sangareddy District
2012-13, the entire district is covered by hard rock except 0.2% of the alluvium
area. Groundwater occurs in unconfined to confined conditions in hard rock
and recent alluvium formations. The depth of borewells, constructed by
CGWB under Canadian Assisted Groundwater Project, ranges from 48.5 to
193 m.
Jinnaram Mandal is classified as “Non-critical” for groundwater usage.
The depth to water varies from 3.85 m bgl to 21 m bgl during pre-monsoon;
while for post-monsoon, the data ranges from 0.98 m bgl to 22.65 m bgl.
