EFFECT OF GOURNDWATER CONTAMINATION ON SITE SPECIFIC ZONES OF PUDUCHERRY STATE

Groundwater is the only source of drinking water for residents of Puducherry State. This study examines the presence of hazardous ions in the open wells, dug wells and bore wells of Puducherry state. The hazardous ions were determined using standard operating methods for the examination of water. The result of the analysis shows that metals such as pH, TDS, Alkalinity, TDS, Total Hardness, Calcium, Magnesium and Iron were not found in most of the observation water samples, while other traces such as Chloride, Sulpahte, Fluoride and Nitrite are within the permissible limits as prescribed by W.H.O. This study suggests that monitoring of the quality of groundwater should be undertaken regularly to identify the magnitude and source of toxic pollutants, which are responsible for the contamination of groundwater quality in the study area. I. INTRODUCTION In the recent past Puducherry State is rapidly industrializing due to its geographic location, near sea shore, highly skilled man power, resource availability in the near districts like Cuddalore near and Villupuram of Tamil Nadu. Industrialization has caused a lot detrimental effects on the natural resources such as ground water being polluted with hazardous ions. Such ions are spatially migrated through ground water aquifers. Such migration of ions gets unnoticed as people gets used to it. Hazardous ions like iron, calcium, magnesium cause health hazards to public. Along with human and economic loss there were serious changes in the ecology and environment. There was already a serious risk of contamination by fecal matter, salinity with the lack of proper sanitation infrastructure and hygiene knowledge.
