Abstract: Groundwater is one of the earth’s most widely distributed and most important natural resources. Groundwater exists, wherever water penetrates beneath the surface. The rocks beneath the surface are permeable enough to transmit water, and at places, the rate of infiltration is so sufficient that the rocks are saturated to an appreciable thickness. This water may be fresh or brackish in quality. As the fresh water constitutes very little quantity of the total water available, we must think as to how best we can exploit it, and utilize it. With the growth of population, today in many of the places water has become a critical source. In many places it is dwindling both in quality and quantity, creating problems for the communities involved. Water Quality Index indicates the quality of drinking water by assessing physical, chemical and biological parameters of water. India had the most studies, with 177 articles, followed by China, Brazil and the United States. This four countries together published 57% of studies on WQI. Groundwater quality implies the level of concentration of different constituents of water which is ultimately described if it is suitable or not for drinking or other purpose such as irrigation. There are mainly three types of constituents or parameters for describing quality of groundwater as physiological, chemical and biological parameters. These parameters are described below: EC ,TDS, K, Na, Ca ,Mg ,TH, Co3, HCO3, Cl, SO4 ,and also we determine some trace element such as Copper (Cu) ,Lead (Pb), Manganese (Mn) ,Nickel (Ni) ,Iron (Fe), Zinc (Zn). Keywords: Gokul Shirgaon , Hydrogeochemical , GroundWater

Eastern U.S. blackberries (Rubus subgenus Rubus) have advanced in recent years in production and quality of cultivar choices. Mainly a pick-your-own and local sales item of the early 1990s and before, the increased presence of blackberries in retail grocery stores in the last 10 years has broadened the market for this small fruit. Cultivars that can be shipped and have extended shelf life have been the cornerstone of this expansion. Also, off-season production in Mexico has provided fruit for retail marketing during most months of the year. Further advances in production, marketing, and consumption can be achieved with the continuation of improved cultivar development and expansion of production technology.
