Customer Problem
Reseda Lake is a man-made lake, approximately 2.5 acres in size and 9 feet deep, in a
recreational area of Reseda Park. The lake is polluted from the droppings of birds and the
decomposition of food that has been scattered in the water by visitors who feed the birds (see
chart below for baseline pathogen measurements).
Goal
The lake water in Reseda Lake should meet or exceed the city standards for lake water quality, consistent with the standards established by the Department of Natural Resource (see chart below for standards the pilot project was tasked to achieve).
Methodology
A baseline measure of metals and microbes were established in October 2008 prior to the treatment using SCD Probiotics products and technology (see chart below). All samples were analyzed for total, E. Coli, Enterococcus and Total Colifoms bacteria, as well as copper. The microbial culture formulation and application process designed and developed by the SCD Probiotics technology team in partnership with California-based Organic Environmental Technology.
Product applications began in March 2009. A solid microbial culture (Magic Sinkers) were placed at various strategic locations along with activated wood charcoal (Impregnated Carbon) and a liquid microbial culture (Pond Magician) was injected at the aerator unit. Samples at six locations around the lake were taken on June 24, 2009.
Results
The table below represents the significant improvement in water quality on all levels, with sample results testing far below the City Standards.
Water Quality Improvements at Reseda Lake
based on SCD Probiotics Technolgy application
*Average of six samples taken prior to the start of the SCD Probiotics applications, in north, south, east, west and center of the lake
**South side of Reseda Lake is where the majority of the ducks, geese and other bird life enter the lake
Next Steps
Due to the overwhelmingly positive results in this test application, the City of Los Angeles has plans to sign a contract with Organic Environmental Technology (OET) of Los Angeles to clean up mile-long Cabrillo Beach, San Pedro California - a popular swimming, surfing and scuba diving destination. Technical support will be provided by SCD Probiotics technology staff and products and customer service provided by OET.
