Assessment of Water Quality of Himayat
Sagar Lake
Hyderabad,
Telangana State, India, Using
Physico-Chemical Parameters.
2. Introduction
.
The storage capacity of the lake is about 4
TMC.
an artificial lake about 20 km from Hyderabad
e lake catchment area about 1346 sq km
3. Himayat Sagar and Osman Sagar lakes provided continuous
The water supply to the twin cities of Hyderabad and
Secunderabad until recently.
4. *saving the city from floods
*The road atop the lake is popular for a
5. The grassy area adjoining the lake is an ideal place
for picnic and recreation spot.
6. What is the purposes of thisWhat is the purposes of this
studystudy.
* Himayat Sagar is one of important source of
drinking water
*increasing water pollution day by day required
continuously monitoring and assessment to the all
parameters of water and what type of treatment
should adopted if the parameters not within
acceptable levels
7. Scope and Objectives
1- assess the quality of water collected from this lake
2-Analysis of pollution status of the Lake
3-Studying the long-term effects on the ecosystem.
4- Conducting the status and monitoring of
wetland resources by studying their Physico
-Chemical parameters.

alkalinity and fluoride
TDS is high in samples No (2 & 3 & 4 & 5 & 12 )
For Total alkalinity is high in samples NO(12 & 13)
Fluoride is high in samples no ( 12 &13)

19. TDS
is a measure of the amount of material dissolved in water. This
material can include carbonate, bicarbonate, chloride, sulfate,
phosphate, nitrate, calcium, magnesium, sodium, organic ions,
and other ions
Water with high TDS often has a bad taste and/or high water
hardness, and could result in a laxative effect.
Factors Affecting Total Dissolved Solids
Geology and Soil in the Watershed
Urban Runoff
Fertilizer Runoff
20. Alkalinity is a measure of the
buffering capacity of water,
Measuring alkalinity is important in
determining a stream's ability to
neutralize acidic pollution from
rainfall or wastewater
Factors Affecting Alkalinity
Geology and Soils
Changes in pH
Sewage Outflow
21. Fluoride
Level in water Effects
0.8–1.2 mg/l Prevention of tooth decay,
strengthening of skeleton
Above 1.5 mg/l Fluorosis: pitting of tooth
enamel and deposits in
bones
Above about 10 mg/l Crippling skeletal fluorosis
Fluoride is a desirable substance: it can
prevent or reduce dental decay and
strengthen bones, thus preventing bone
fractures in older people
24. Total Hardness
In the study area TH ranges from 25-155 mg/lit with an
average of 85.8 mg/lit. All samples are within the acceptable
limit (IS 10500:2012).
Fluoride
In the study area concentration of Fluoride
in the water samples ranges from 0.5-2.2 mg/lit with an
average of 0.7 mg/lit. All samples are within the acceptable
limits (IS 10500:2012).
