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.

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

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).
