The Listin Diario reports that the Peter Anderson survey that tested waters off the southeastern coast of the DR concluded the country needs to invest in more water treatment plants in the area to meet the increasing population. It showed that biological contamination has been going on for years and is moderate, but urges governmental attention in order to preserve the coasts where numerous tourism destinations have sprung up and the populations continue to increase. The study says the worst contamination was found at the river mouths in the areas studied. The Peter Anderson ship surveyed the waters from the Haina and Ozama rivers in Santo Domingo to San Pedro de Macoris province, in the southeast. The research was requested by the Ministry of Environment and was funded by the US Environmental Protection Agency. The findings were presented by the Ministry of Environment on World Earth Day.
