GAZA CITY (Ma'an) -- Half of the beaches in Gaza have dangerous levels of contamination and are unfit for swimming, the Palestinian environmental authority said Tuesday.
The Ministry of Health, together with the environmental authority, takes samples along the coast every month to test levels of pollution and contamination.
Khalid Abu Ghali, a spokesman for the environmental authority, told Ma'an that over 50 percent of the beaches are not fit for swimming and the agency has contacted concerned parties and lifeguards to identify areas with high levels of contamination.
Maps explaining which beaches are safe will be posted in public areas, he added.
The main cause of contamination is the low quality of sewage treatment stations which pump waste-water into the sea.
Three stations in Gaza City, Khan Younis, and Rafah do not function properly because of continuous power cuts due to a lack of fuel, Abu Ghali said.
Waste-water is often pumped directly into the sea without being treated due to the power cuts.
In 2012, the United Nations published a report warning that Gaza will no longer be "liveable" by 2020 unless urgent action is taken to improve water supply, power, health, and schooling.
An Israeli blockade on Gaza has been in place since 2006, limiting imports and exports and leading to major economic decline and a wide-reaching humanitarian crisis.
