Water Testing Guide
When to Test Your Water
- When moving to a new home - Establish a baseline for your water quality
- If you have a private well - Test annually (wells aren't monitored like municipal water)
- After plumbing changes - Disturbances can release lead from old pipes
- If you notice changes - New taste, odor, or discoloration
- If pregnant or have infants - Extra caution with vulnerable populations
- Living near contamination sources - Industrial sites, farms, or known contamination areas
What to Test For
The contaminants you should prioritize depend on your situation:
| Situation | Priority Tests | Recommended Kit |
|---|---|---|
| New homeowner (city water) | Lead, bacteria, general quality | Tap Score Essential |
| Private well owner | Bacteria, nitrates, lead, pesticides | Tap Score Advanced |
| PFAS concern (east metro) | PFAS compounds specifically | Tap Score PFAS Test |
| Regular monitoring | Basic parameters, quick check | Varify 17-in-1 |
Understanding Your Results
Test results are compared against EPA Maximum Contaminant Levels (MCLs). Lab tests typically include detailed explanations of what each result means and whether action is recommended.
What to Do If Contaminants Are Found
- Don't panic - Many contaminants can be effectively removed with the right filter
- Verify the result - Consider a second test if levels are borderline or unexpected
- Choose appropriate filtration - Match filter capabilities to detected contaminants
- Report serious issues - Contact your water utility or MDH for significant contamination
