Frequently asked
What water filter do I need in Worcester?
Based on the published record: Lead 2 µg/L, below the 15 µg/L action level; detected below the limit. If you choose to filter, look for lead-certified carbon filter, or reverse osmosis, certified to NSF/ANSI 53 (lead). PFAS: PFPeA 3.2 ng/L detected (no federal or state limit); detected, no federal or state limit. If you choose to filter, look for reverse osmosis, or carbon certified for PFAS, certified to NSF/ANSI 58 or 53, with PFPeA named on the listing. Pick a model whose certification names each contaminant you want to reduce.
Does "NSF certified" mean a filter removes everything?
No. Certification is per contaminant: a filter certified to NSF/ANSI 42 for chlorine taste says nothing about lead or PFAS. Check the certifier's listing (NSF, WQA or IAPMO) for the exact model and the exact contaminant.
Is a pitcher enough for lead in Worcester?
A pitcher certified to NSF/ANSI 53 for lead reduces lead in the water you pour through it; replace cartridges on schedule. For a lead service line, replacing the line is the lasting fix; ask the utility about its replacement program.
