Out of the several groundwater samples taken from the project area in the Hortobagy region in east of Hungary between years 2001 to 2006, 10 samples (5 each from summer and winter) were chosen and studied for microelements, especially heavy metals. The samples were analysed for chromium, zinc, cobalt, nickel, barium, aluminium, copper, molybdenum, boron, lead, cadmium, strontium and lithium at the MaFI Lab using ICP-OES. The data was refined and the plots hence were studied for variation over the given time period and seasonal variation between the 10 wells, and along the depth. The observations are useful to determine whether there has been any noticeable variation in the concentration on the elements beyond safe limits. The WHO-EU safe water standards are used to determine the quality of the water.
