Project 2: Evaluation of groundwater for domestic and agricultural purposes

Project 2: Evaluation of groundwater for domestic and agricultural purposes

Introduction:

Ground water is being widely used in many parts of the country for drinking and irrigation purpose. However, there are reports of falling water quality from different states. The drought affected areas still depending on groundwater are facing serious problem. In many parts of the country, gypsum is used effectively in reducing the sodicity problem. Increasing concentration of salts due to heavy use of fertilizers over years is common. This project proposes to identify the problem and make student aware of its remedial measures.
.
Objectives:

1. To gather information about change in ground water quality over a period of time
2. To examine the quality of ground water
3. To suggest remedial measures based on water quality

Methodology:

Project data base can be collected by using a questionnaire. Information can also be collected from local government organizations like ground water department. Questionnaire should include name, locality, source of ground water, level of ground water depth, color, taste, no of families using water and area under irrigation. Students can collect water samples and analyse for their physico-chemical properties like pH, EC, salinity, alkalinity using soil test kit. Finally water quality can be assessed,

Relevance:

Based on quality, salinity and alkalinity of the water can be grouped and probable reclamation measures can be suggested. Reclamation practices like placing gypsum at canal entry level or passing water through gypsum bed can be demonstrated
