Instant Water Report Analysis

Get a Personalized Water Filter Recommendation

Enter your water report results to compare against EPA limits, identify contaminants like PFAS and lead, and instantly get a personalized whole-house or RO water filter recommendation.

Before you start

  • Gather your latest certified lab report or municipal Consumer Confidence Report (CCR)
  • Enter the number and select the correct unit from the dropdown — the tool will automatically convert as necessary
  • Leave any field blank if it was not tested; at least one parameter is required to run a recommendation
  • Unsure which numbers matter? Start with pH, hardness, iron, manganese, nitrate/nitrite, lead/arsenic, and any bacteria results

This tool provides guidance based on your water test results and may not always be 100% accurate. For especially complex water chemistry, we recommend consulting a Crystal Quest water filtration specialist for a personalized assessment or second opinion.

EPA Drinking Water Standards

The EPA sets Maximum Contaminant Levels (MCLs) for over 90 substances in drinking water. Here are the key standards our recommendation tool uses to analyze your water report.

< 50% of MCL 50 – 80% of MCL 80 – 100% of MCL > 100% of MCL

Safe

< 50% of MCL
Well within limits

Caution

50 – 80% of MCL
Monitor regularly

Warning

80 – 100% of MCL
Treatment advised

Exceeds MCL

> 100% of MCL
Treatment required

Common Contaminants in U.S. Drinking Water

Millions of Americans have tap water that exceeds EPA safety limits1. Here are the most frequently detected contaminants and zero-tolerance threats to watch for in your water report.

Most Frequently Detected

  • 1 Lead Pipes & fixtures
    MCL: 15 PPB
  • 2 Arsenic Natural & industrial
    MCL: 10 PPB
  • 3 Nitrate Agricultural runoff
    MCL: 10 mg/L
  • 4 Iron Well water & pipes
    MCL: 0.3 mg/L
  • 5 Manganese Groundwater
    MCL: 0.05 mg/L

Zero-Tolerance Contaminants

  • 1 Total Coliform Bacteria indicator
    MCL: 0
  • 2 E. coli Fecal contamination
    MCL: 0
  • 3 Cryptosporidium Parasite
    MCL: 0
  • 4 Giardia lamblia Parasite
    MCL: 0
  • 5 Legionella Bacteria
    MCL: 0

MCL = EPA Maximum Contaminant Level. Any detection of zero-tolerance contaminants requires immediate treatment. Browse Crystal Quest filtration systems or use our recommendation tool above to find the right solution for your water.

Water Quality & Filtration Questions Answered

Get clear answers to common questions about water testing, reading your water report, and choosing the right filtration system for your home.

A water quality report lists detected contaminants alongside their EPA limits. For each substance, compare the detected level to the Maximum Contaminant Level (MCL):

  • Below MCL: Within safe limits, no treatment required
  • At or near MCL: Monitor closely, treatment recommended
  • Above MCL: Exceeds safe limits, treatment required

Pay special attention to lead, arsenic, nitrate, and bacteria — these pose the greatest health risks even at low concentrations. Our recommendation tool above automatically compares your results against every EPA standard and flags exceedances with color-coded alerts.

At minimum, every water test should include:

  • Basic parameters: pH, hardness, TDS, iron
  • Health-critical: Lead, nitrate, coliform bacteria

Well water users should also test for:

  • Arsenic, manganese, fluoride, and radon
  • Uranium and radium in areas with granite bedrock
  • Hydrogen sulfide if you notice a rotten egg smell

If you notice staining, taste, or odor issues, add iron, manganese, tannins, and sulfur to your test. A comprehensive lab test covering 30+ parameters gives the most complete picture and allows our tool to generate the most accurate filtration recommendation.

It depends on your specific contaminants:

  • Whole house treatment needed: Hardness, iron, manganese, sediment, hydrogen sulfide, and low pH. These affect your entire plumbing system, water heater, and appliances
  • Point-of-use (under-sink) works best for: Lead, arsenic, nitrate, fluoride, and other drinking water contaminants. A reverse osmosis system under the kitchen sink is often the most effective and economical option

Many homes benefit from both — a whole house system for general water quality (hardness, iron, sediment) plus an RO system specifically for drinking and cooking water purification. Our recommendation tool analyzes your full water report and suggests the right combination.

The tool applies EPA standards together with Crystal Quest’s internal engineering methodology to generate a personalized whole house system.

  • Standards-based analysis: Your contaminant levels are evaluated against regulatory limits and health-based guidelines
  • Engineering thresholds: Additional internal treatment benchmarks are applied to determine practical treatment needs
  • System configuration: Media types, tank sizing, and filtration stages are selected to address your specific water chemistry

The result is a complete whole house filtration system designed around your exact water profile — not a generic pre-built package.

No report yet? Start with a professional water quality test to get the most accurate recommendation.

The EPA recommends testing private well water at least once per year for bacteria, nitrate, and pH. Beyond that:

  • Test immediately if: You notice changes in taste, odor, color, or water pressure
  • Test after events: Flooding, nearby construction, new agricultural activity, or plumbing changes
  • Test every 3-5 years for: A full panel including metals, radiological, and organic compounds

City water users: Your utility sends an annual Consumer Confidence Report (CCR), but independent testing is still recommended if you have older pipes or concerns about lead. Keep in mind that the CCR measures water at the treatment plant — not at your tap, where lead and copper contamination from your own plumbing can occur.

Each time you get new results, run them through our recommendation tool to see if your filtration needs have changed.
