The document analyzes groundwater quality in Visnagar Taluka, Gujarat, focusing on data collection and assessment for drinking and irrigation purposes over pre-monsoon and post-monsoon periods. It emphasizes the evaluation of various physicochemical parameters against Indian standards, revealing significant deviations from permissible limits in multiple samples. The findings conclude that certain villages have poor groundwater quality, necessitating purification for safe consumption.

 Introduction

4.  Ground water quality is indicated by the
amount of dissolved or suspended inorganic
or organic material in it through which it
acquires physical and chemical characteristics.
 Under natural condition, the composition of
ground water depends on the composition of
rainwater, soil strata and aquifer materials
and changes with time and space.

34.  Total 15 water samples are fall above the permissible limit
of IS:10500 and the water samples from the Kamalpur
site is not fit for drinking because parameter like EC,
TDS,Ca2+,Mg2+,SO3
- are above the permissible limit of IS.
 All the water samples for pH value is within acceptable or
permissible limits of IS: 10500. Fluoride concentration is
higher than permissible limit of IS: 10500(2012) in the
villages like Jetalvasana, Tarabh and Visnagar Rural.
 It is concluded that from above 15 villages which has poor
ground water quality are not used without purification.

35.  Analysis of IRRIGATION WATER
The suitabibty of an irrigation water depends upon
several factors, such as,
• Water quality
• Soil type,
• Plant characteristics,
• Irrigation method,
• Drainage,
• Climate and the local conditions.
QUALITY CRITERIA FOR IRRIGATION
a) Total salt concentration,
b) Sodium adsorption ratio,
c) Residual sodium carbonate or bicarbonate ion
concentration
