EDCs are difficult to measure and filter due to their small size and underappreciation. With their nanometrical size, physical methods of separation may be too expensive or too difficult to implement. Besides, there is no easy way of quantifying them other than specific protocols that most of the time involve expensive equipment or laboratory conditions.

Not quantifying them results in the lack of regulations in water treatment plants and the non-existing laws and regulations in the federal regime in Mexico of micro fibers and EDCs. In addition, there aren’t any mentions of these compounds in the Official Mexican Norm or Norma Oficial Mexicana NOM.201-SSA1-2015 “Sanitary specifications of products and services. Water and ice for human consumption” [6]. The same happens with NOM-127-SSA1-1994 “Environmental health, water for human use and consumption” [7]  and with NOM -003-ECOL-1997 [8] “Pollutants in wastewater treatment for public service reuse” [9]. Dr. Roeb García from “Centro del Agua para América Latina y el Caribe” made an analysis of the regulatory frameworks of the emerging water pollutants in Mexico and the world. In his research, he concluded and confirmed that Mexico and Latin America don’t have enough regulations respecting microplastics and EDCs as water pollutants. [10]
