Gravimetric Laboratory Service:
The TAMS Center provides a gravimetric laboratory (filter weighing) service through a contractor and is currently taking applications from tribes
whom are interested in using this service. Tribes and tribal consortia are eligible to apply for this service. Current guidance on how to use
this service is being revised by the TAMS Steering Committee and will be available soon.
Generally, the service is for a limited term of up to a maximum of 1 year to allow tribes to get started with conducting air monitoring projects.
Along with the weighing of sample filters the TAMS Center assists with data review and data validation to help tribes with their quality assurance
requirements. Tribes interested in this service should complete the TAMS Center gravimetric laboratory service application.
