Routine Drinking Water Panels
Select a drinking-water panel for the source, location and concern rather than an all-contaminants package. Utility tap water, private well water and treated water need different sampling questions; total coliform/E. coli, nitrate, metals and organic targets are separate methods.
Use the laboratory's bottles, preservation, storage and delivery instructions. First-draw versus flushed lead samples assess different conditions; do not substitute a generic bottle or assume clear water is free of contaminants.
A strip or meter is screening for the properties it measures, not equivalent to certified laboratory analysis. Verify the provider's certification/accreditation for the actual analyte, matrix and programme; results describe submitted samples, not perpetual safety.
