Paros DEYA undertakes all planned sampling checks for drinking water throughout the year in collaboration with privately accredited laboratories based on the legislation and in accordance with the Joint Ministerial Decision Γ 1(δ) / Γ Π οικ.67322/2017 “Quality of water for human consumption”.
DEYA Paros also participates in a program developed by the Association of Municipal Water Companies to inform citizens about the quality of drinking water through the website https://edeya.gr
The results of the analyses show that the water of the supply network is drinking water, of very good quality for its microbiological and chemical composition, while it has moderate to high hardness which is attributed to the hydro-geological conditions of the island. Find HERE more details about drinking tap water.
At the same time, DEYAP has installed 5 water distribution systems, coin or prepaid-card operated, which provide excellent quality soft water to the consumers. They apply the reverse osmosis method to process water of the network, removing part of its hardness.
A typical analysis of the produced water is displayed in the table below:
|Cations (mg/l)||Ca ⁺⁺||Mg ⁺⁺||K⁺||Na ⁺||NH₄⁺|
|Anions ( mg/l )||Cl ⁻||HCO₃⁻||SO₄⁻||NO₃⁻||NO₂⁻|
|Total Hardness in mg/l CaCO₃: 150|
|Conductivity 400μS/cm ( 25⁰C )|
|Solid residue ( 180 ⁰C ) 250ppm|
Control of radioactivity
DEYA Paros in cooperation with the Hellenic Atomic Energy Commission carries out radioactivity measurements in potable water according to “Joint Ministerial Decisions” no. Π/112/1057/2016 / 01.02.16 (B’241/2016) on “Establishing health protection requirements for the population against radioactive substances contained in water for human consumption, in compliance with Council Directive 2013/51/EURATOM, of October 22, 2013”.
The results of the measurements show that the water of the water supply network of DEYAP is completely free of radioactive substances.
