Analysis

What to know about Franconia's water

Franconia ranks #63 out of 119 cities in New Hampshire for water quality, placing it below average in the state.

Franconia relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.

Lead levels exceed the EPA action level of 15 ppb, which typically indicates aging lead service lines or lead solder in the distribution system. An NSF 53-certified filter is strongly recommended for drinking and cooking water.

As a small community water system, Franconia may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

What Franconia residents can do

Install a water filter

Recommended: NSF 53-certified pitcher or under-sink filter. This addresses the specific contaminants found in Franconia's water.

Request your utility's CCR

Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.

Flush your taps

Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.

Monitor alerts during storms

Franconia's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.
