Colorado Springs water meets all EPA legal limits. Each of the 9 tested contaminants below sits under its limit — most by a wide margin.
The one real caveat: lead and copper usually enter from a home's own plumbing, not the treated supply. If your home was built before the mid-1950s, older service lines and solder are the thing to check — not the water coming out of the treatment plant.
Note: independent health group EWG flags 9 detected contaminant(s) as above its own much-stricter voluntary benchmark — shown in the table below as informational only, not a safety claim. Every one sits below the legal EPA limit.
Why it's safe
- ✓ Continuous monitoring — Colorado Springs Utilities tests the water around the clock for microbiological safety and routinely for chemical parameters.
- ✓ Regulated to EPA limits — enforced under EPA National Primary Drinking Water Regulations.
- ✓ Disinfected — chlorine keeps the supply safe from bacteria from the treatment plant to your tap.
What's in Colorado Springs's water
Detected contaminants reported for Colorado Springs Utilities (EPA system ID CO0121150).
Source: EWG tap water database (Aug 2026).
Every detected contaminant is below the health limit. Some are still above EWG's stricter voluntary health benchmarks — common nationwide, shown below.
How to read this table: the legal limit (the EPA's Maximum Contaminant Level (MCL)) is the enforceable safety line — it's what regulators actually require. The EWG guideline column is a much stricter, voluntary health benchmark (often 100–1000× lower than the legal limit). Many contaminants sit below the legal limit but above the EWG line — that's common nationwide and means the water is still legally safe, not that it's dangerous.
| Contaminant | Typical level | EPA legal limit | EWG guideline | Status |
|---|---|---|---|---|
| Bromodichloromethane | 5.18 ppb | unregulated | 0.06 ppb | Above EWG |
| Chloroform | 31.1 ppb | unregulated | 0.4 ppb | Above EWG |
| Dibromochloromethane | 0.996 ppb | unregulated | 0.1 ppb | Above EWG |
| Dichloroacetic acid | 10.4 ppb | unregulated | 0.2 ppb | Above EWG |
| Haloacetic acids (HAA5) | 27.5 ppb | 60 ppb | 0.1 ppb | Below limit |
| Haloacetic acids (HAA9) | 37 ppb | unregulated | 0.06 ppb | Above EWG |
| Radium, combined (-226 and -228) | 1.11 pCi/L | 5 pCi/L | 0.05 pCi/L | Below limit |
| Total trihalomethanes (TTHMs) | 37.3 ppb | 80 ppb | 0.15 ppb | Below limit |
| Trichloroacetic acid | 14.9 ppb | unregulated | 0.1 ppb | Above EWG |
Levels are system-wide utility averages. The legal limit is the EPA's Maximum Contaminant Level (MCL). EWG also flags 9 contaminant(s) as exceeding its own stricter (non-legal) health guideline — shown as an informational note only, not a safety claim.

What actually matters in Colorado Springs's water
Most of the numbers in the table are below the legal limit and aren't worth your worry. Here's the honest read on the ones people actually ask about in Colorado Springs:
Why the limit exists: Trihalomethanes are disinfection byproducts. Long-term exposure above the limit is associated with liver, kidney, and central nervous system problems plus an increased risk of cancer (most consistently bladder). The limit is a deliberate trade-off: you can't remove them without abandoning disinfection, which would risk far worse microbial disease.

Why the limit exists: Haloacetic acids are disinfection byproducts associated with an increased risk of cancer at sustained elevated exposure. Same trade-off as TTHMs — the limit balances cancer risk against the necessity of disinfection.

Where Colorado Springs's water comes from — and how it's treated
mountain snowmelt reservoirs (Blue River, Fountain Creek)
Like every U.S. municipal supply, Colorado Springs's water is disinfected and monitored against EPA National Primary Drinking Water Regulations, published annually in the Consumer Confidence Report (CCR). If you want to read the raw report for yourself, our how to read your water quality report guide walks you through it line by line.
"My Colorado Springs water tastes or smells like chlorine — is it still safe?"
Yes. A chlorine taste or smell doesn't mean the water is unsafe — it's the residual disinfectant doing its job (preventing bacteria from re-growing between the treatment plant and your tap). Seasonal changes, disinfection byproducts, or your own plumbing can all shift taste without affecting safety. If the taste bothers you, a simple activated-carbon pitcher filter removes it without any safety concern — the water was already safe before you filtered it.
Water quality vs. water hardness — don't confuse the two
"Water quality" (is it safe to drink) and "water hardness" (how much scale it leaves) are entirely different things — and confusing them leads to bad purchases. See the Colorado Springs water hardness page for the hardness picture.
If contaminants concern you — add a drinking-water filter
Should you filter Colorado Springs's water?
The softener handles hardness; a drinking-water filter removes Radium and removes Trihalomethane — if Colorado Springs's reported levels concern you. EPA: Radium is radioactive and long-term exposure is associated with an increased risk of bone cancer and other effects. EPA: Total trihalomethanes (TTHMs) are disinfection byproducts associated with an increased risk of bladder cancer and possible reproductive effects at long-term elevated exposure. For a full breakdown of what each filter type removes, see best whole-house water filters.

When to call a professional
Colorado Springs's water meets every legal limit, so there's nothing that requires a pro — but clean, good-tasting water is always worth a little peace of mind, and your home's plumbing is its own variable. The clearest reason to call a licensed plumber: if your home was built before the mid-1950s and may still have lead service lines or solder — the lead risk lives in your pipes, not the city's water. Beyond that, a professional can test your tap (not just the city-wide report) and tell you honestly whether any treatment would actually improve what your household drinks.
Certified, independent results come from a state/province-licensed lab, not a company with a sales incentive — ask for a lab that reports to the EPA or your state.
Frequently asked questions
Is Colorado Springs tap water safe to drink?
Yes. Colorado Springs's municipal water meets all EPA legal limits — every detected contaminant is below the limit. Lead is the main thing to watch, and it usually comes from a home's own plumbing, not the treated supply.
Who tests Colorado Springs's water, and how often?
Colorado Springs Utilities is required by the EPA to test and publish an annual Consumer Confidence Report (CCR), linked on this page.
Where does Colorado Springs drinking water come from?
mountain snowmelt reservoirs (Blue River, Fountain Creek)
Should I filter Colorado Springs's tap water?
For most people, no — the water already meets all legal limits. A filter is worth considering only if you're on older plumbing (lead/copper), have a compromised immune system, or dislike the taste/chlorine.
Is Colorado Springs water hard?
See the Colorado Springs water hardness page — hardness is a separate concern from safety.
