What we can help with

• Data corrections — if a hardness, ppm, source, or utility value is wrong, tell us and we'll verify it against the primary report.
• Missing cities — want your city added? Include (if you can) a link to your utility's water-quality report.
• Partnerships — affiliate, sponsorship, or content inquiries.
