Our Recommendation for San Benito
San Benito's resaca-fed system runs hot on disinfection byproducts: TTHM at 66 ppb with individual samples reaching 72.8 against the 80 ppb federal limit, and dibromochloromethane at 63.5 µg/L. Compliant, but with thin margin — and DBPs are precisely what RO with carbon polishing strips out. The brackish NanoH2O (formerly LG) BW 400 R G2 covers the mineral base of this Rio Grande-system water at the same time.
