Weck Laboratories, Inc. participates in all mandatory Proficiency Testing (PT) programs required under the different certification programs.  The most common are Water Supply (WS), Water Pollution (WP),  Hazardous Waste (HW) and Underground Storage Tank (UST) and Radiochemistry (RAD) PT samples that are each analyzed twice per year.  Every year, over 1600 individual parameters are analyzed as blind samples and results processed by a certified third party PT provider that sends the results to the different accreditation agencies for review.  In addition, the laboratory participates in other non-mandatory and special PT programs and Round Robin studies.  These include NDMA at low levels, 1,4-dioxane and low level perchlorate PT studies, client specific blind samples and internal PT samples ordered for parameters that are not part of the standard Proficiency Testing programs.   Copies of results of PT studies are available by request.
