Calidad del agua potable en Texas

Esta página resume los registros del EPA sobre los sistemas públicos de agua potable activos en Texas. Los sistemas listados corresponden a la categoría comunitaria del SDWIS (CWS) — sistemas que sirven a una población residente estable durante todo el año. Las violaciones reportadas siguen la clasificación regulatoria del EPA: basada en salud, monitoreo o reporte.

El conteo de violaciones cubre los últimos 5 años a partir de la fecha del volcado de SDWIS. Las cifras se actualizan cada trimestre cuando el EPA publica un nuevo volcado. Las detecciones de PFAS provienen de la Unregulated Contaminant Monitoring Rule y solo cubren los sistemas que participaron en la ronda correspondiente.
