Bowman was contracted to provide environmental sampling, analytical and quality assurance services for the Tahoe Keys Control Methods Test, a study evaluating the first-ever use of herbicides in Lake Tahoe. The project required specialized monitoring within Lake Tahoe, a unique alpine lake designated as a Clean Water Act Outstanding Natural Resource Water.
During an intensive four-month monitoring period, Bowman collected and analyzed more than 1,065 surface water and sediment samples from more than 30 sites using specialized boat-deployed sampling protocols and equipment. The team also performed more than 960 real-time, in-field fluorometer analyses using rhodamine dye as a surrogate for herbicide presence.
To support data quality and regulatory compliance, Bowman developed and followed strict QA/QC protocols for water quality field instrument calibration. The team also coordinated sampling, data review and reporting activities to address Lahontan Regional Water Quality Control Board permit requirements.
Throughout the project, Bowman collaborated with the TRPA, Lahontan Regional Water Quality Control Board, Tahoe Keys Property Owners Association and analytical laboratory partners. This coordination supported a comprehensive monitoring program designed to generate reliable environmental data and meet the regulatory requirements associated with this first-of-its-kind study in Lake Tahoe.
