CHRONICLES OF THIRST: DOCUMENTING MYKOLAIV'S WATER SECURITY CHALLENGES AND SOLUTIONS IN A WAR-AFFECTED CITY Why does turbidity not decrease when sulfates decrease? We distinguish three main factors: 1. Long-term use of aggressive salt water in 2022-2024 led to irreversible corrosion. Even "clean" water, passing through these highways, is enriched with fine iron and sediment. 2. Constant pressure drops and repairs on the lines keep corrosion products in suspension. With a turbidity of 7 NTU, the water has a distinct yellowish tint, which makes it visually unacceptable to the public. 3. A change in the chemical composition of water in early 2026 (including a slight drop in pH) contributes to the further dissolution of old scale and rust, which only keeps the NTU levels high. An indicator of 7 NTU and above is a critical barrier to the city's "water war culture". This means that household reverse osmosis filters and flow cartridges fail 5-10 times faster than the standard period; water remains "technical. The stability of the turbidity index at the level of 7 + NTU against the background of improvement in other parameters allows us to draw an important conclusion: Mykolaiv is faced with the effect of "contaminated network memory". Even if the water at the outlet of the treatment plant is ideal, the condition of the city pipes will continue to generate high turbidity. The forecast for 2026 is still disappointing: without a massive replacement of intra-block networks or the use of special stabilization reagents, the indicator of 7 NTU will remain constant, leveling the success of demineralization. 85
