In a first ever census on the wells in kerala it has been found that there are nearly 70 lakh open wells with a yearly increase of 3.31 percent in their numbers. This was revealed in a study conducted by a team of experts headed by M.Nazimuddin, head of the Ground water department of the centre for water resources Development and Managemnt, Kozhicode. The finding sof this study could be an excellent database when regulations on water withdrawel have to be brought in ona later stage. The average well density of the state have been found to be 298 wells per sqkm. But in several urban areas, such as the kazhakkoottam are on Thiruvananthapuram district there are as many as 1000 wells in one sq.km. on an average there are 500 wells per sq.km in coastal area, 277 in midland and 117 in highland. However the study hasw also founfdthat E.coli an indicator organism of feacla pollution was found to be present in over 83 percentage of wells in rural kerala. A major reason attributed for this is the fragmentation of land holdings and the reducing distances between the wells an dthe septic tanks or sewerage lines.
