Assessment of Water Quality of Himayat Sagar Lake Hyderabad,
Telangana State, India, Using Physico-Chemical Parameters.
Introduction
.
The storage capacity of the lake is about 4 TMC.
is an artificial lake about 20 km from Hyderabad
The lake catchment area about 1346 sq km
Himayat Sagar and Osman Sagar lakes provided continuous The water supply to the twin cities
of Hyderabad and Secunderabad until recently.
*saving the city from floods
*The road atop the lake is popular for a good drive
The grassy area adjoining the lake is an ideal place for picnic and recreation spot.
What is the purposes of this What 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
Scope and Objectives 1- assess the quality of water collected from this lake
2-Analysis of pollution status of the Lake3-Studying the long-term effects on the
ecosystem.4- Conducting the status and monitoring of
wetland resources by studying their Physico -Chemical parameters.

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 WatershedUrban Runoff
Fertilizer Runoff
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 SoilsChanges in pH
Sewage Outflow
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

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).
FluorideIn 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).
