Environmental Laboratory

The St. Johns County Utility Environmental Laboratory (SJCUEL) analyzes samples for the St. Johns County Utility Department to ensure that county entities meet all State and Federal regulations. SJCUEL is a National Environmental Laboratory Accreditation Conference (NELAC) certified laboratory staffed with three employees who strive to produce high quality data. SJCUEL provides quality field and laboratory analysis to protect and enhance the water quality in St Johns County. The laboratory is open from 7:00 am to 4:30 pm Monday through Friday and can be reached at (904) 209-2667.

County employees collect samples from wastewater treatment plants, water treatment plants, monitoring wells, rivers and land application sites. Chemists in the Laboratory (Lab) analyze those samples in the trace metals, nutrients, microbiology, and Wet Chemistry laboratories. In an average year, the Lab analyzes over 10,000 samples. Data from the analyses are validated and stored on a Laboratory Information System. This information forms a database that is used to: Design and operate wastewater treatment plants, enforce industrial waste regulations, formulate plans and action programs to protect and enhance local water bodies, and protect public health.

SJC Utility Quality Assurance
