Hidralia, the company responsible for the supply of water in decline in the municipality of Marchena, carries out permanent analytical controls throughout the distribution system (networks and tanks) in compliance with the self-control protocol approved by Health and in accordance with current Legislation. Beyond the analysis and quantification of the legally required parameters, Hidralia, in order to improve the guarantee and safety of people's health and the quality of drinking water, incorporates into this analytical control plan, the determination of another series of additional parameters expanding the spectrum on pesticides and other elements over and above what is established in the regulations. In this sense, it has been possible to determine the presence of a pesticide compound (MCPA) in amounts slightly higher (0.11 µg/l) than the legal limit (0.1 µg/l) on February 15, 2021 and verifying the presence of the same in contrast sample within 24 hours after the initial sample.

The company, immediately after detecting the situation, has implemented the established protocols, communicating the detection of this parameter to the various responsible bodies.

The latest controls and counter-analysis to confirm these values, rule out that the detection of this compound is related to the municipality's water distribution process. Therefore, and in order to ensure the health of citizens, the supply company in coordination with the Marchena City Council, makes available to the Écija Plan Consortium, responsible for the production and supply of water in discharge to the town, how many Human and material means are necessary to study the origin of the problem and collaborate in its resolution. Likewise, they are made available to the health authority to make as many additional determinations as necessary, establishing, where appropriate, the appropriate protocols to minimize the impact on the population.

It should be remembered that the values ​​established in RD140/2003 are intended to establish the sanitary criteria that drinking water must meet, to guarantee the health, quality and cleanliness of the water in order to protect people's health from adverse effects. derived from any type of water pollution if the exposure to these compounds were made on a chronic and continuous basis, which has not occurred so far in this specific episode.
