Argentina's Buenos Aires province government will draw up a new plan to expand infrastructure to meet the growing needs of the urban population, the provincial government said in a release.
In particular, authorities aim to target districts that currently have poor sanitation and potable water services, according to local news source Terra.
The plan includes boosting the percentage of households with a sewerage connection to 75% from 50% in 2007, and those with potable water to 70% from 62%.
"It's important that we know what to do in each place experiencing [water contamination] problems with arsenic, nitrate, fluorine and drought," said infrastructure minister Cristina Alvarez.
Projects will initially be carried out in cities Bahía Blanca and La Plata, including construction of a potable water treatment plant for Pehuajó and 9 de Julio, and a distribution system in the northeast of the province that will channel water from San Nicolás to Villegas.
