For laboratories

Why Certify With DWLCA

You already meet the minimum. Certification with DWLCA is how you prove — to inspectors, realtors, engineers, utilities, and homeowners — that you go well past it.

A seal that means something

Because every DWLCA seal links to a live registry entry, your customers can confirm in five seconds that a real assessor was in your lab this year. Labs that don't get audited annually can't say that.

Win the inspector and realtor channel

Home and well inspectors choose labs for their clients. A verifiable, third-party mark on your reports is a reason to choose you — and to keep choosing you.

Catch problems before your customers do

Annual audits and blind samples find drift, training gaps, and custody holes early. Most labs tell us the first audit paid for itself in what it caught.

Field collection, certified

The optional Field Sample Collection Program lets you certify the people who collect for you — ending the "who took this sample?" problem on every report.

Fair, transparent process

Published standard, fixed fees, defined finding classes, a real appeals path, and assessors barred from any conflict of interest. No surprises.

Not a competitor

DWLCA does not test water. It never will. Our only business is evaluating laboratories.
