Research and Development is ongoing on the dugwells in which water contains organic odor and high fecal coliform, occurring mainly when the dugwell is fairly new. The water is treated with lime and, in cases of high fecal coliform levels, is also treated regularly with theoline, the disinfectant that contains 5% chlorine. Villagers are advised not to use the water for a few days during the period of shock treatment. Water analysis to measure the concentration of arsenic levels and total and fecal bacteria of all functional dugwells will be routinely done after construction. Also, every summer when the water levels drop, arsenic levels are measured. Project Well keeps a database evaluating the use of the dugwells (see attached newsletter). Consumers are visited monthly by the grassroots level field workers and asked about outbreaks of diarrhea and dysentery among users of each dugwell. In the winters of 2004 and 2005, door-to-door village surveys were carried out to create the database of the existing dugwells and observation of any outbreaks. There have been no such outbreaks linked to any particular dugwell water use over a period of four years.
