A Quality Assurance Project Plan (QAPP) was developed for the Big Pine Paiute Tribe of the Owens Valley by Blue Tomorrow. The objective of this QAPP is to allow the Tribe to collect groundwater samples at BP-Res 5, a monitoring well located on the Reservation. The water quality data to be collected as part of this project, as well as the groundwater level data, are part of the Tribe’s groundwater monitoring program.
