Ocean Outfall Monitoring: Ponce, Puerto Rico
Puerto Rico Aqueduct and Sewer Authority (PRASA)
Ocean Surveys provided water quality monitoring services at an ocean outfall monitoring site to support a 301(h) Waiver and Mixing Zone Validation Study offshore Ponce, Puerto Rico.
OSI field teams conducted 11 quarterly surveys at the Ponce effluent outfall. Services included: “clean technique” water sampling, ADCP current monitoring, CTD/DO/pH vertical profiling, benthic sediment grab sampling, and ROV pipeline inspection.
OSI collected ROV video along the entire length of the outfall structure, including six diffuser risers.
