Stormwater Monitoring Program – Beach Cities Watershed Management Group

EcoKai plays an integral role in implementation of the Beach Cities Watershed Management Group’s (BCWMG) Stormwater Monitoring Program in accordance with the Los Angeles County Municipal Separate Storm Sewer System (MS4) Permit outlined by Section 402 of the Federal Clean Water Act. The BCWMG includes the southern California coastal cities of Manhattan Beach, Hermosa Beach, Redondo Beach, and Torrance. The objective of the MS4 Permit is to ensure that discharges in the County of Los Angeles do not cause or contribute to the exceedance of water quality standards in regional water bodies. The MS4 Permit includes monitoring requirements for stormwater flow monitoring and water quality sampling, non-stormwater (dry weather) flow monitoring and sampling, receiving water quality sampling, and applicable TMDL standards.

Since 2016, EcoKai has been providing monitoring services to BCWMG that includes the installation and maintenance of instrumentation within storm drains and channels to measure, record, and transmit water flow data, performing field water quality sampling during storm events, dry weather flow source investigations, dry weather microbiological source tracking investigations, coordinating laboratory analyses for water quality constituents of concern, and data analysis and preparation of annual integrated monitoring compliance reports.
