Water is a precious natural resource available on the planet Earth. About two third is water on the planet Earth but the usable water mainly for drinking purpose is very less. Fast developmental activities have put pressure on surface water and groundwater. Groundwater is highly important for drinking, agriculture and industrial purposes in the world. Groundwater quality plays an important role for drinking purpose. Many diseases like fluorosis, methemoglobinemia, arsenocosis are due to poor quality of drinking water. In urban areas, groundwater quality is deteriorated due to solid and liquid wastes disposal. The present study has been carried out to assess groundwater quality for drinking purpose in south-eastern part of Panchkula city, Haryana. In the present study eight groundwater samples were collected in the month of June 2019 from different locations in the study area. Groundwater samples were analyzed using Field Water Testing Kit prepared by Tamilnadu Water Supply and Drainage Board (TWAD), Chennai for ten chemical parameters-pH,hardness, chloride, fluoride, iron, ammonia, nitrate, nitrite, phosphate and residual chlorine. Chemical analysis of groundwater samples show that in the groundwater samples pH ranges-7 to 7.5, hardness 100 mg/l to 250 mg/l, chloride 40 mg/l to 110 mg/l, fluoride 0.5 mg/l to 1 mg/l, iron nil, ammonia nil to 3 mg/l, nitrite 0.2 mg/l to 0.5 mg/l, nitrate 20 mg/l to 75 mg/l, phosphate nil to 1 mg/l, residual chlorine nil to 0.2 mg/l. As per BIS drinking water standards pH, chloride, fluoride, iron, nitrite, phosphate, residual chlorine is desirable in all the eight groundwater samples; hardness is desirable in four groundwater samples and permissible in four groundwater samples; ammonia is desirable in six groundwater samples and non-potable in two groundwater samples; nitrate is desirable in seven groundwater samples and non-potable in one groundwater sample. Groundwater quality at Govt. Primary School, Ramgarh, Govt. Senior Secondary School, Ramgarh and Sector-28-C, Panchkula is desirable and at Market Ramgarh, Sector-25, Panchkula, Sector-28-A, Panchkula, Sector-28-B, Panchkula is permissible and Sector-26, Panchkula is non-potable. The study gives a scenario of groundwater quality for drinking purpose in the study area. The study can be used for monitoring groundwater quality for drinking purpose.
