Component
Earthy and musty is usually drought, not danger.
As reservoirs shrink, geosmin and MIB from natural organic matter concentrate. They taste unpleasant but are not considered harmful, and activated carbon is built to reduce them.

Drought and your tap water
Drought changes your water. Your pour can taste clean.
A dry summer can leave tap water tasting earthy, musty, or more like chlorine. Pure XP is a carbon block filter built for exactly that: chlorine taste and odor and the organic compounds drought concentrates, plus broad everyday reduction.

Better tasting summer water
Less single-use bottle waste
The quick picture
Less water in the reservoir means more flavor in your glass. Here is why summer 2026 tastes different.
Nearly half the country has been in drought this year, with North Carolina logging its driest stretch since 1895 and the Colorado River heading into a record-low year. When source water drops, what is left becomes more concentrated, and your tap can taste earthy, musty, or more like a pool.

More chlorine taste is common in summer.
Utilities often adjust disinfection on lower-quality, warmer source water, so a stronger chlorine taste or odor shows up. NSF/ANSI 42, which Epic carries, is the standard for reducing it.
Always honor a boil or do not drink notice.
A filter improves taste and many chemical concerns, but it is not a substitute for a utility advisory. If your area gets one, follow it first.
Why NSF 42/372 belongs on this page
Drought is mostly a taste and odor problem, and NSF 42 is the taste and odor standard.
NSF/ANSI 42 covers aesthetic effects like chlorine taste and odor, the exact thing that changes when source water runs low. NSF 372 verifies lead-free materials in contact with your water. Pure XP and Nano XP carry both, so you fix the flavor without adding a new material worry.
The simple checklist
What a carbon filter can and cannot fix in a drought.
1
Great fit for carbon
- Chlorine taste and odor that climbs in summer.
- Earthy, musty flavors from geosmin and MIB.
- Many organic compounds, plus PFAS, lead, and VOCs.
2
Needs a different tool
- Arsenic and uranium, more common in low-flow groundwater.
- Nitrate from concentrated runoff.
- These generally call for reverse osmosis, not carbon.
3
Not a filter job
- Cyanotoxins from harmful algal blooms.
- Any issue under a boil or do not drink advisory.
- Follow your utility first, then filter for taste.
Inside the filter
The visual version: off-tasting water goes in, carbon gets to work, cleaner water comes out.
CoreXchange media is built around activated carbon, which is the textbook answer for the taste and odor problems drought creates. The story is simple: adsorption grabs the compounds behind that earthy, musty, or chlorine flavor, while the same media also targets a range of everyday chemical concerns.
01
Taste and odor adsorption
Carbon targets chlorine, geosmin, and MIB in the pour path.
02
Broad contaminant focus
Pure XP also targets PFAS, lead, VOCs, and chlorine taste/odor.
03
Format fit
Pure XP, Nano XP, dispenser, or under-sink depending on routine.

Quick answers
Drought and tap water FAQ, minus the wall of text.
Why does my tap water taste or smell worse during a drought?
When reservoirs and rivers run low, naturally occurring compounds like geosmin and MIB become more concentrated, which gives water an earthy or musty taste and smell. Utilities also tend to adjust disinfection on lower-quality source water, so you may notice more of a chlorine taste or odor in summer. These taste and odor changes are usually aesthetic rather than a sign the water is unsafe.
Is drought tap water safe to drink?
In most cases, public water that meets federal standards is still safe to drink even when it tastes earthy or like chlorine. The taste and odor compounds common in drought, such as geosmin and MIB, are not considered harmful. Always follow any boil water notice or do not drink advisory from your local utility, since those address specific safety issues that a filter cannot replace.
Will a carbon filter fix the earthy, musty taste from drought?
Yes, this is exactly what activated carbon is designed for. Carbon block filters like Epic Pure XP are built to reduce chlorine taste and odor and many of the organic compounds that cause earthy and musty flavors. Reducing these aesthetic taste and odor effects is the core of the NSF/ANSI 42 standard our filters are certified to.
What does a carbon filter not remove during a drought?
Drought can also concentrate inorganic contaminants like arsenic, uranium, and nitrate in some regions. Activated carbon is generally not the right tool for those, which typically require reverse osmosis or other specialized treatment. Cyanotoxins from harmful algal blooms are also not something a standard pitcher filter is designed to remove, so always follow your utility's guidance if a bloom advisory is issued.
Why do NSF/ANSI 42 and NSF 372 matter?
NSF/ANSI 42 is the standard for aesthetic effects such as chlorine taste and odor, which is precisely what changes during a drought. NSF 372 verifies lead-free compliance for materials that come into contact with your drinking water. Epic Pure XP and Nano XP carry both.
Is a filter better than buying bottled water in summer?
A reusable filter usually costs far less per gallon than bottled water and avoids the single-use plastic. One Epic cartridge can replace the equivalent of over a thousand single-use bottles, which is a practical way to get better tasting water through a long, dry summer.
How often should I replace my filter?
Replace your filter according to the recommended filter life to maintain optimal contaminant reduction and water flow. If your water has been tasting earthy or strongly of chlorine all summer, a fresh cartridge helps ensure your system keeps performing as designed.
