How to Read Your Water Quality Report (Consumer Confidence Report): Honest Guide
If you’re wondering what’s actually in your tap water — and whether you need a shower filter — the first place to look is your Consumer Confidence Report (CCR). Every public water system in the US is required to publish one every year.
We’re Zooshen — we make shower filters. What we’ll tell you is the honest version: how to find your report, what to look for, and which numbers actually matter for your shower.
What Is a Consumer Confidence Report?
The Consumer Confidence Report (CCR) is an annual water quality report that every public water system in the United States is required to publish under the Safe Drinking Water Act.
It tells you:
– Where your water comes from (river, lake, groundwater, etc.)
– What contaminants have been detected
– Whether those contaminants are within EPA legal limits
– Health effects of any violations
How to Find Your CCR
- Check your water bill — most utilities include the CCR or a link with your annual bill
- Search online — go to EPA’s CCR search tool and enter your zip code
- Call your water utility — ask them to send you a copy
What to Look For (For Shower Filter Decisions)
You don’t need to read the entire report cover to cover. Focus on these key numbers:
1. Disinfectant Used: Chlorine or Chloramine?
This is the most important number for choosing a shower filter.
- Free chlorine → KDF-55 media works great
- Chloramine (chloramine) → you need vitamin C media
Look for “chlorine” or “chloramine” in the disinfection section. If it says chloramine, KDF alone won’t cut it.
2. Hardness (Grains per Gallon or mg/L)
If the report lists hardness:
– < 1 GPG: Soft water, minimal scale
– 1–3.5 GPG: Moderately hard
– > 3.5 GPG: Hard water
Note: a shower filter won’t soften hard water. You’d need a whole-house water softener for that.
3. Total Dissolved Solids (TDS)
TDS measures everything dissolved in your water. It’s a general indicator, not specific to shower filters.
- < 300 mg/L: Good
- 300–600 mg/L: Acceptable
- > 600 mg/L: Noticeable taste / mineral load
4. Specific Contaminants to Watch For
Look for:
– Lead — any detectable level is concerning (children and pregnant women especially)
– VOCs (volatile organic compounds) — industrial solvents, byproducts
– Pesticides / herbicides — agricultural runoff
– Nitrates — agricultural runoff, dangerous for infants
Note: most shower filters don’t remove lead, VOCs, or pesticides. Those need a whole-house or under-sink system.
What the Report Won’t Tell You
- Shower exposure — the report is about drinking water, not inhalation or skin absorption during showering
- Temperature effects — hot water releases more chlorine gas than cold water
- Your home’s pipes — lead from old pipes won’t show up in the municipal report

Frequently Asked Questions
Where can I find my Consumer Confidence Report?
Check your water bill, or use the EPA’s CCR search tool by entering your zip code.
Is my tap water safe to drink?
If your CCR shows no violations, yes. Most municipal water in the US meets EPA standards.
Do shower filters remove lead?
Most shower filters don’t remove lead. If lead is a concern, you need a certified under-sink or whole-house system.
What’s the most important thing to look for in my CCR for shower filters?
Whether your water uses free chlorine or chloramine. That determines which media you need.

The Bottom Line
Your Consumer Confidence Report is the first step to choosing the right shower filter. The most important number is whether your water uses chlorine or chloramine — that determines which media works.
