  • Abstract:
    In the Tahoe Basin, strict surface water discharge limits of 20 NTU for turbidity and 0.1 mg/L

    for total phosphorus are due to come into effect in 2008. The main concern in terms of water

    quality is the discharge of fine particles and nutrients into Lake Tahoe. The overall goal of this

    project was to determine the feasibility of low intensity chemical dosing (LICD) for improving

    highway storm water runoff quality in the Lake Tahoe Basin. A primary objective was to

    identify promising coagulant chemistries for turbidity and phosphorus reduction that could be

    tested further in small-scale and full-scale pilots. This project combined literature reviews,

    laboratory studies (charge titration and jar test experiments using synthetic and actual storm

    water runoff) and settling column studies to assess treatment performance and feasibility. A

    related project funded by the U.S.D.A. Forest Service (through the City of South Lake Tahoe)

    for which the Caltrans funds for this study provided the match has investigated ecotoxicity issues

    associated with coagulant treated storm waters in the Tahoe Basin.
