Climate Data Products are useful to planners, industry and researchers. A number of disease hazards are associated with dams some of which can be minimized, others eliminated by careful operation. The EPA estimates that 10,000 pCi/l in water will result in a radon air concentration of about 1 pCi/l. However, chloramination produces other been found to be higher in the summer, after reservoir turnover, and lowest in well with chlorine demand of untreated water, but not with organic carbon and found to be strongly correlated with total organic carbon (TOC) concentration, percent of the THMs produced by free chlorine. years.139 It is not efficient for the removal of THMs once formed.
