December 15th, 2014 (InsideCostaRica.com) One million people who rely on community water systems known as ASADAs are receiving tap water contaminated with fecal matter, the Costa Rican Institute of Aqueducts and Sewers (AyA) said during a Friday press conference at AyA headquarters.
AyA executive president, Yamileth Astorga told reporters that the institute plans to address the problem in 2015, which especially affects those living in rural areas, 82% of which rely on community ASADAs for their water supply.
“We must ensure universal access to safe water and sanitation,” Astorga said.
Biological contamination not a new problem
A September 2013 report by the Comptroller General’s office indicated that 370 community-operated water systems in the country were contaminated with microbiological and other elements in excess of allowed limits.
In the 2013 report, contamination was found in the greater San Jose metro area and the Central Pacific, in addition to rural areas.
In addition to excessive microbiological contamination, the 2013 report found contamination by agrochemicals, grey water, excessive amounts of iron and calcium, and hydrocarbons. The report said that insufficient water treatment was in large part to blame.
According to the 2013 report, as many as 1,350 community water systems are not chlorinated at all. Those that do treat their water and were visited by the Comptroller General said they have never received the advice of AyA in regards to proper dosage or treatment methods. Operators who do chlorinate their supplies use a number of varying methods, from chlorination pills, sodium chloride and liquid chlorine.
