    Dry weather runoff from urban creeks is a typical source of bacteria in coastal California. Beyond the Golden State, bacterial contamination of oceans, lakes and streams concerns many municipalities as well as they strive to reach increasingly stringent urban runoff and stormwater regulatory requirements. An innovative solution—ozone treatment for urban runoff—applied at two California beaches ...

  • How a LEED Platinum Building is Cleaning up Inland Empire Urban Runoff

    ABSTRACTIn 2002, the Inland Empire Utility Agency (IEUA) – a municipal water agency in western San Bernardino County - designed and constructed its new Headquarters with the goal of attaining the first 2.0 platinum level “LEED” - Leadership in Energy and Environmental Design - rating established by the U. S. Green Building Council.” IEUA has implemented a BMP project that truly showcases the ...

  • Stormwater input of pyrethroid insecticides to an urban river

    The American River flows for nearly 50 km through highly urbanized lands surrounding Sacramento, California, USA. Twenty‐three streams, drainage canals, or pumping stations discharge urban runoff to the river, with the cumulative effect of nearly doubling the river's flow during rain events. During winter storms, the water column in the most downstream 13‐km reach of the river exhibited toxicity ...

  • How to Plan Stormwater Management for Urban Areas

    Water is a vital commodity in our lives, but it is possible to have too much water all at once in our lives, especially following violent storms or snow melt. This excess water, lying on the ground, swelling rivers, canals and drains to over-capacity is known as stormwater. In order to make the best use of this water, local authorities need to safely contain stormwater while any ...
