Regular Data Verifications

Daily and monthly data verifications check to see if the numbers make sense, and if there are any errors that need to be identified and corrected. Use the "library" tab above to direct to QA related documents, including a presentation on QA in data management & validation in collaboration with with EPA R9 staff.


Regular Maintenance & Calibrations

Weekly, bi-weekly, quarterly, semi-annual and annual maintenance checks are performed to make sure the instruments are operating properly, and to see if there are any problems to be fixed. We primarily use a Streamline Pro for regular flow checks, and aim to combine Bios Defenders & DeltaCal meters for calibrations.


Regular Outside Audits

A 3rd party audit of all monitoring systems is conducted annually at the station. Additionally, specialized staff from the Great Basin Unified Air Polluion Control District (GBUAPCD) have conducted quarterly equipment inspections to verify our local results. Recent audit reports are published and available via the "library" tab above.


Inter-Agency Assistance

The Bishop Paiute tribe participates in inter-agency quality assurance and monitor maintenance activities with neighboring tribes and agencies in CA and NV. This can involve trainings, audits, regular quality assurance checks, maintenance, installations, and any other type of technical assitance.
