To insure quality results, Dellavalle utilizes internal quality control checks with replicate samples, matrix spikes, external or control samples and method blanks. Additionally, we employ Good Laboratory Practices (GLP). Our performance is evaluated by California’s Environmental Laboratory Accreditation Program for water and wastewater and the North American Proficiency Testing program for manure, compost, soil, plant tissue and ag water.
