Corrosion control in drinking water distribution networks is an important aspect and the effects of corrosion may not be evident. Without a monitoring record there are significant issues in relation to public health and economic aspects. There are water quality parameters that are related to the chemical stability of water, such as: pH, temperature, Total Dissolved Solids (SDT), alkalinity, calcium hardness, sulfates and chloride in mg / l. These parameters were used to determine the corrosive tendency or fouling of drinking water in the potable water supply network in the city of Azogues. The Langelier Saturation Index (IL), Ryznar Stability Index (IR) and Larson-Skold Index (ILS) were calculated using the above parameters in order to evaluate the chemical stability of the potable water samples that were taken during six month samplings. The experimental results reduced during the six months (from July to December), of the three incidents of chemical stability indicated: according to the Index of Langelier there is strong corrosion; Ryznar index indicates very severe corrosion. While according to the Larson-Skold Index there is significant corrosion, the parameters that significantly affect the indexes are for: Langelier index, pH and hardness as Calcium in mg / l, for Ryznar Index, pH, and hardness as calcium in mg / l, and for the Index Of Larson-Skold we have sulfates; The present study demonstrated the application of water stability indexes, classifying it as corrosive.

This document presents the physical-chemical parameters with the objective of evaluating and analyzing the drinking water quality in the Azogues city applying the water quality index (WQI) and to research the water stability in the distribution network using corrosion indexes. Thirty samples were collected monthly for six months throughout the drinking water distribution network; turbidity, temperature, electric conductivity, pH, total dissolved solids, total hardness, calcium, magnesium, alkalinity, chlorides, nitrates, sulfates and phosphates were determined; the physical-chemical parameters were measured using standard methods. The processed data revealed that the average values of LSI, RSI and PSI were 0.5 (± 0.34), 6.76 (± 0.6), 6.50 (± 0.99) respectively. The WQI calculation indicated that 100% of the samples are considered excellent quality water. According to the Langelier, Ryznar and Pukorius indexes showed that drinking water in Azogues is corrosive. The quality of drinking water according to the WQI is in a good and excellent category.
