You cannot determine whether water is safe to drink from its appearance, taste, or smell, or from the information and tools on this site. Only testing by an appropriate laboratory can establish water quality.
Our tools provide estimates based on the inputs and assumptions you provide and do not account for every real-world condition. Do not rely on them to size, select, or install equipment without professional confirmation and manufacturer data.
If you suspect contamination — especially bacterial contamination or after flooding — stop using the water for drinking and cooking, use a safe alternate source, and contact your local health department or an accredited laboratory. For electrical or pump work, consult a qualified professional.
