About SDC Laboratory

25 Years of Expertise

SDC Lab was created as a community-minded corporation in 1992. We operate with a quality assurance plan (QAP) and know the value of safe and sustainable water. We endeavor to protect fundamental resources. We believe in responsible agriculture. And we are proud to service our local community, as well as clients across Colorado, New Mexico, Utah, Arizona and beyond.


Women- and Minority-Owned

Evelyn Vigil is the founding visionary behind SDC Laboratory. Evelyn’s exacting standards and 45 years of experience (including working for the federal government as a research chemist) distinguished SDC. Evelyn retired in 2017 and continues to advise SDC’s core projects. Current owner and laboratory director, Julie Zahringer, continues the organization’s expertise, excellence and legacy as a woman- and minority-owned business.

About Our Name

The Sangre de Cristo mountains, a majestic subrange of the Rocky Mountains, with 10 dramatic peaks that rise above 14,000 feet,are the inspiration for our name. Visitors to the lab can enjoy a view of these just outside our laboratory door.

A river of knowledge. At SDC Laboratory, rest assured that our team is made up of innovative, people-oriented chemists and microbiologists with unparalleled expertise.
