Where the water comes from
Lanagan PWS draws water from 2 wells.
Annual water quality report
Lanagan PWS must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.
Systems serving 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Lanagan PWS for a copy.
Find a posted report with EPA's Consumer Confidence Report search
Testing your own water
To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by Missouri.
Certified drinking water labs by state EPA guidance for private wells
