State General Laboratory Annual Report 2019

40 State General laboratory Annual Report 2019 Swimming pool water  Chemical control (Conductivity, pH, Total Residual Chlorine, Free Chlorine, Total Alkalinity)  Microbiological control (Total coliforms, Escherichia coli , Total Bacteria Count 37 o C, Staphylococci species, Pseudomonas aeruginosa ) Effluents Domestic effluents - treated water Water scarcity and increased needs due to population growth as well as lifestyle and climate changes make the safe reuse of recycled water from liquid municipal waste extremely important for the water balance of Cyprus. An important prerequisite for the use of recycled water is strict quality control to ensure the protection of hu- man health and the environment from possible effects of the long-term use as well as to address the concerns and bias of citizens towards the use of recycled water. The quality control of recycled water includes both chemical and toxicity control:  Chemical control (pH, conductivity, residual Chlorine, BOD5, COD, Suspended Colids, Chlorides, Nitrates, Sulphates, Boron, total Phosphorus, Kjeldahl-Nitrogen, metals (Calcium, Magnesium, Potassium, Sodium, Zinc, Copper, Lead, Cadmium, Mercury, Chromium, Nickel), Carbonates, Bicarbonates, pesticides and Polycyclic Aromatic Hydrocarbons (PAHs), in total 20 compounds, in treated domestic wastes. PAHs have also been determined in sediments using another method  Determination of toxicity (Recycled water of tertiary wastewater treatment plants: Microtox Test using Vibrio fischeri (EC50-TU50 measured at 5', 15' and 30'), Daphtox Test using Daphnia magna (EC50-TU50 measured at 24 and 48 hours), Algaltox test using Pseudoklebsiella subcapitata (EC50- TU50 measured at 72 hours) Atmospheric Air Quality of outdoor air  Chemical control (Metals (Aluminium, Calcium, Iron, Potassium, Magnesium, Sodium, Zinc, Titanium, Vanadium, Chromium, Maganese, Nickel, Cobalt, Copper, Arsenic, Cadmium, Tin, Barium, Mercury, Lead), Anions (Fluorides, Chlorides, Bromides, Nitrates, Phosphates, Sulphates), Cations (Lithium, Sodium, Ammonium, Potassium, Magnesium, Calcium), Polycyclic Aromatic Hydrocarbons (PAHs) (Benzo(α)anthracene, Benzo(j)fluoranthene, Benzo(b) fluoranthene, Benzo(k)fluoranthene, Benzo(α) pyrene, dibenzo(a,h)anthracene, Benzo(g,h,i) perylene,indeno(1,2,3-cd)pyrene)  Radioactivity levels (Gamma Radionuclides, Gross β- activity, Gross alpha activity, Ruthenium-106)
