Case Studies

Petaluma River & The Bahia Wetlands

Novato, CA

The Problem

Noxious odors caused by high levels of hydrogen sulfide (H2S) were reported throughout the Petaluma River Basin and San Francisco Bay Area. H2S concentrations within the wetlands area were measured at 330 ppb+.

The Bay Area Air Quality Management District’s maximum standard for hydrogen sulfide is 30 ppb.  The West Bahia Lakes are owned and managed by the California Department of Fish and Wildlife (formerly the California Department of Fish and Game).

Our Solution

AQ-4  was applied to remove odors and nutrients, stimulating diatoms and local beneficial microbes to accelerate aquatic recovery. Our AQ-4 treatment significantly improved water quality making West Bahia Lake the cleanest lake with the most wildlife use in the entire Petaluma River wetlands basin.


    Microbetech products proved to be very effective, removing the odors and digesting the floating carcasses of thousands of dead fish that covered over two miles of our lake shoreline.  I would recommend Microbetech natural products for anyone that wants to improve, enhance and preserve their environment.

    Your bioremediation process represents a significant departure from, and a vast improvement over, historical algal control methods, e.g. treatments with toxic chemicals such as copper and chlorine; and we wish you continued success.

    “AQ bioremediation products hold a great deal of promise as a substance useful in helping to balance systems disrupted by human activities.”
