PFAS en el agua potable de Puerto Rico
Esta página reúne las detecciones de PFAS reportadas por sistemas públicos de agua en Puerto Rico bajo el Unregulated Contaminant Monitoring Rule (UCMR) del EPA. Los datos solo cubren los sistemas del estado que participaron en la ronda UCMR correspondiente.
El sitio reporta los registros tal como EPA los publica. Cuando un compuesto tiene un proposed MCL, las detecciones que superan ese nivel se contabilizan en la página de cada compuesto. Aquí mostramos el conteo por compuesto en el estado y la lista de detecciones individuales con el nivel original.
