Analysis

What to know about Torrington's water

Torrington ranks #64 out of 65 cities in Wyoming for water quality, placing it among the lowest-rated in the state.

Torrington 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.

PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter.

While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.

The system has seen 61 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Key contaminant findings

Based on the most recent EPA sampling data for Torrington's water supply.

Lead Elevated
Detected: 10.0 ppb Limit: 15 ppb (EPA Action Level)

Within EPA limits but above the American Academy of Pediatrics recommended level of 1 ppb. An NSF 53-certified filter provides additional protection.

Copper Exceeds Limit
Detected: 1.82 mg/L Limit: 1.3 mg/L (EPA Action Level)

Exceeds EPA action level. Copper can leach from household plumbing — flush taps for 30 seconds before drinking.

PFAS (1 compound) Elevated
Detected: Highest: lithium at 61.9000 µg/L Limit: 0.004 µg/L (EPA MCL)

Detected but within current EPA limits. PFAS do not break down in the environment and can accumulate in the body over time. An activated carbon filter can reduce exposure.

Violation history

Torrington's water system has 211 total violations on record, including 63 health-based violations. 23 remain unresolved. 61 violations were issued in the last 5 years.

Where does Torrington's water come from?

Torrington's drinking water comes from groundwater (wells), supplied by 6 water systems serving approximately 7,662 people. Groundwater is generally less susceptible to surface contamination but can contain naturally occurring contaminants like arsenic, radon, and nitrate.

What Torrington residents can do

Install a water filter

Recommended: Activated carbon or reverse osmosis filter. This addresses the specific contaminants found in Torrington'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.

Where Torrington's water comes from

Groundwater

Torrington's drinking water is drawn from underground aquifers through wells.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.

Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.

The system is operated by local government ownership and serves approximately 7,662 people through 6 water systems.
