Agenda
Introduction to AgroRemed Case studies
Other products Q & A
Copyright 2007; Sarva Bio Remed, LLC 3
Technology Products are developed on the basis of our
patented biodispersion technology Key elements of technology
Biodispersion: Bacteria first Disperse oil into water into smaller droplets
Bioutilization: These oil eating bacteria consume oil broken down into droplets
Products are oleophilic and bacteria attach to the oil Are effective 1:10 ratio of product to oil
There is no waste for disposal

AgroRemedCleanup of Contaminated Soils
AgroRemed is used for cleanup of petroleum contaminated soils (PCS)
It is easy to apply and is a one time application
The TPH levels are reduced to accepted levels in short time period
Turn around time reduced and cleanup costs reduced effectively

Cleanup of Soil After a Residential heating oil Spill in PA
About 50 gallons of heating oil spilled Cleanup did not remove fumes Soil and ground water were impacted Sprayed once with product In 21 days the VOCs were reduced
effectively and even after 12 months the VOC were in BDL

Cleanup of contaminated soil in a shipyard in VA
The shipyard was planning expansion The soil was impacted with hydrocarbons The ground water showed presence of free
product It was not possible to excavate as the site
was on the river VA DEQ recommended that AgroRemed is
used for the cleanup

Overview of the site Application of AgroRemed

Results after 4 months Focus of the project was to prevent groundwater
contamination Periodical examination showed that the levels of
free product was more The free product that was less than 10th of an
inch was now more than 12 feet 139 gallons free product was pumped out Mobilization of oil was attributed to AgroRemed There is no free product in the ground water now

Cleanup of contaminated soil at a terminal in VA
An oil terminal had a long history of contamination
The first incident was recorded in 1991 The levels of contamination was high both in
soil and ground water Routine cleanup protocol was followed In 2005 one more complaint was filed In 2006 AgroRemed was studied as a pilot
Copyright 2007; Sarva Bio Remed, LLC 11
Results after 3 weeks The pilot study was for 3 weeks only Two samplings were made
After 10 days After 20 days
There was more than 30% reduction in 10 days
The reduction after 20 days was more than 95%
Use of AgroRemed was recommended

Restoration of vegetation after a highway spill
100 g. diesel and 10 g. motor oil was spilled on Rte 522 in VA
The grass alongside the embankment was killed
Vegetation below the embankment was denuded
Excavation was not possible After 49 days, it was decided by V DOT to use
AgroRemed for cleanup

The site before application of AgroRemed
The grass seeds were planted immediately after spray with AgroRemed near the guard rail. Fresh grass began to grow in a weeks time. The vegetation on the right had received a greater impact of the spill. The TPH of the soil was 65,000 ppm. TPH was reduced in less than 3 weeks time to 26,000 ppm after first application of AgroRemed. At the end 3 months the TPH was less than 850 ppm and the vegetation began to grow healthily

Cleanup of highway spill with AgroRemed in West Virginia
75 gallons of diesel spill on a WV highway The spill was more on the embankment near
the guard rail Conventional excavations were not possible
because of utility lines Some of the unmarked utility lines were
broken during excavations WVDEP agreed that in situ treatment is the
only available option

Application of AgroRemed
TPH of the soil was 47,000 ppm. Gravel was brought for fresh fill and the soil was treated with AgroRemed. Conditions along the road requires multiple application and at the end of 61 days, the TPH of the soil at the 4 monitoring site was less than 500 ppm and in one site it was below detectable limits

Damage to Asphalt by Diesel
It was pointed by VDOT during discussions that asphalt is very permeable to diesel and hence can affect the life of the pavement. We tried to do some research and there was only one report available on the effect of diesel on asphalt. According to this report Resilient modulus of core samples was reduced by half in 2 weeks time due to the dissolution of binder by diesel in the asphalt. In wheel tracker test, the maximum rut depth of 15.35 mm was recorded for diesel saturated slabs in 2 hours time.

Benefits of AgroRemed in highway spills
It is available in a ready to use liquid form so easy to apply.
Treatment is on site and non-invasive Reduces the contamination aggressively and
in one spill situation TPH of 45,000 was reduced to 93 ppm in 3 weeks time
Effectively de-toxifies soil and so favors growth of plants and other life.
Generally a one time application
