This document provides an activity report summarizing the results of the Montreux Clean Beach Project from November 11, 2014 to August 31, 2015. Key details include:
- 81 clean-up operations were completed across 6 sites, collecting a total of 1,765 liters of trash.
- Cigarette butts, various plastics, and styrofoam made up the majority of collected trash.
- The Baye de Montreux rive gauche and rive droite sites contributed the most trash, with over 1,000 liters collected between them.
This document provides a draft plan for the Montreux Clean Beach Project II (MCBPII) from November 2015 to November 2016. The project aims to remove trash from shorelines, collect data on accumulation rates using standardized methods, and produce training materials. It will build upon the first project by streamlining data collection and regular communication of results. Volunteers will remove trash, count and categorize debris, and participate in education. Data will help anti-litter campaigns and research by providing a baseline and early warnings on pollution trends over a large area. The benefits are direct environmental and aesthetic improvements as well as information to address diffuse aquatic pollution challenges.
The document summarizes the results of the Montreux Clean Beach Project II from November 2015 to April 2016. Over 16,000 pieces of litter were collected from 9 locations around Lake Geneva through 48 surveys. Plastic made up 87% of the total debris. The top items collected were cigarettes, foam, plastic pieces, glass, and candy wrappers. Data on litter composition and amounts were provided for each individual location. The project aims to evaluate litter mitigation strategies and is conducted through citizen science methods with no funding by the hammerdirt association.
Hammerdirt conducted litter surveys along Cordova Creek in Rancho Cordova, California from November 2015 to January 2016. They collected a total of 1819 pieces of litter across 80 categories. Foam, candy wrappers, shopping bags, and bits of plastic made up 42% of the total litter. The average amount of litter increased by 38.7% over the period. The data collected is available online and helps identify effective litter mitigation strategies, such as targeting areas where food is sold to reduce food packaging waste.

Microplastics were found in all five surface water samples collected from the Dutch portion of the Meuse River. A total of 279 plastic specimens were identified, mostly thin multi-colored fibers. Abundance ranged from 26 particles/m3 at a mid-stream location to 4 particles/m3 at the furthest downstream location. The majority of specimens were fibers that decreased in abundance in the downstream direction, while pieces that remained suspended increased downstream. It is estimated that approximately 19 billion microplastic specimens are discharged annually from the Meuse River into the delta.
Letter to City of Toronto requesting sewage spill cleanup - August 2018LOWaterkeeper
The average rainfall for the entire month of August landed on Toronto in a single 24-hour period on August 7, 2018. Heavy rainfall is known to cause sewage spills on the Toronto waterfront, so the Swim Drink Fish Monitoring Team went to Harbourfront on the morning of August 8, 2018. They found evidence of a major sewage spill that poses a threat to public and environmental health. This letter to the City of Toronto requests immediate cleanup of the sewage debris.
Waste disposal and recycling in Tenerifee-twinning
Tenerife has a large tourism industry that generates significant waste. The island has implemented a Special Territorial Plan for Waste Management to promote prevention, selective collection, recycling, and proper disposal. This includes collecting five containers of waste, composting organic matter, and treating mixed waste. While measures have improved waste management, fully implementing solutions is challenging due to regulations and waste quantities changing. Tourism also contributes to waste issues as some visitors do not follow proper practices.

us about Ulva mass accumulations on Brittany beaches and remedies found to solve this problem. Then, Ardhuin presents his
work about wave hindcasting and forecasting at Previmer within the European project “Integrated Ocean waves for Geophysical
and other Applications”. Third, Faucher et al. provide a description of a coupled Atmosphere-Ocean-Ice forecast system for the
Gulf of St Lawrence in Canada, which has been installed in experimental mode at the Canadian Meteorological Centre. Finally,
Marchesiello et al. are talking about regional ocean forecasting and downscaling strategy at IRD for coastal and submesoscale
phenomena. They have developed a downscaling strategy based on the Regional Ocean Modeling System and produced a new
demonstrator with data assimilation in the Chile oceanic area.
The next October 2010 newsletter will display papers about the Marginal Seas in the MyOcean project.
We wish you a pleasant summer!
The document discusses river litter and plastic pollution. It summarizes initial sampling done in the Meuse River which found significant amounts of plastic litter, with most items being small plastic pieces. An estimated 15,000 plastic items per hour enter the sea from the Meuse alone. There is no clear standard for allowable river litter. Actions proposed include further research, developing recovery solutions, addressing sources of litter, and needing European legislation to give urgency to solving the problem.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

3. Lac Leman and its shores support a rich and diverse ecosystem, provide
an important fresh water supply and are increasingly frequented by tourists
and locals alike. Visible shore pollution undermines the attractiveness of our
region, devaluing the lakeshore economically and negatively impacting
the environment
Lake communities struggle to maintain green spaces, despite investing
much time and money, the amount of trash that arrives on the lake shores,
often by fluvial origins has only increased. Plagespropres.ch offers a simple
strategy to eliminate pollution while effectively monitoring the macro-
pollutants to better manage the lake quality in the future. Plagespropres.
ch is a project based on two pillars:
• Regular and systematic disposal of shore line pollutants
• Documentation of quantity and composition of pollutants
Regular shoreline trash collection reduces the amount of pollution directly
and immediately, benefiting local communities and wildlife. Systematic
identification and documentation provides crucial information. When
compared over time, the data demonstrates the changes in the
composition and quantity of material found on the lake shores and may
be used to track effectiveness of cleanup efforts, as well as information on
the pollution source.

5. The
Method
The shore line is the line of contact between water
and land, the strand-line is a line usually marked by
washed up or stranded aquatic vegetation and other
debris, marking a previous high water level along a
shore.The width of the strandline depends on the
geography of the shore, quantity of material, wave
heights and lake levels (image 1).
In the strand line the trash that is deposited by the
lake is characterized by varying states of decompo-
sition, broken up in small pieces and ambiguous in
origin. The trash is often mixed in with branches,
leaves and other natural material (image2). In these
areas the most efficient way to eliminate the trash is
by hand, making this a tedious and physical job.
Collected by hand for one hour and placed in a bag,
the trash is then spread out for identification, esti-
mation of volume and imaging (image 3). The data
collected depends on the length of the strand line
and the quantity of trash present. Depending on
the volume on site one of two surveys is completed:
an inventory or a frequency survey.
The surveys are completed at the time and place of
collection using the KoboToolbox for andoridOS.
The frequency, time of day and day of the operations
were seleceted at random. For the 40 weeks of the
project there are 81 cleanup operations on six sites:
The trash is disposed of in the nearest public trash
can.The images and results of all operations are
available on the project website:
www.plagespropres.ch

The images and results presented in this
document reflect the trash visible and
collected on the day and at the location
indicated.

6. The frequency survey is composed of 18 « yes or
no » questions and is intended to indicate the
presence of an object in the strand line on the
day of the operation. The result of a frequency
survey is therefore a table with the date at the
column head and the object in question at the
row head.
By dividing the number of times an object was
found (yes) by the number of surveys completed
on the site (yes + no) we get the historical aver-
age of finding that object at the site. (fig 2)
The frequency survey is used when the volume
of trash and time available does not allow for a
complete inventory.

15. Discussion
However, 40 of the 81 operations report a volume
of 10L or less (49%). At low volumes the trash is
composed of different objects.
The results of two inventories of MRG illustrate
this difference. On the inventory of June 13th, with
a volume of 40L, PET bottles, aluminum cans,
straws and food wrappers are all present. On the
other hand, for the inventory of August 11th, with a
volume of 3L, none of those objects were found. (fig
5) (image 12 and 13)
This important drop in volume, -92.5%, between
the two inventories is not reflected in the amount
of pieces of trash found. On June 13 374 pieces of
trash were picked up versus 226 pieces on August
11th; a difference of only -39%. Food wrappers and
bottles are more voluminous than the other objects
collected.
This observation suggests that volume (or mass)
does not sufficiently explain the quantity of trash
found on the beach. The volume does not indicate
the composition, the number of pieces collected
nor does it give any indication of the source or the
frequency of the pollution.
The mean volume of waste collected from all sites
combined is 27,94L per visit. Volume spikes during
weekends and large events are evident. Aproximate-
ly 20L of the 27. 94L can be attributed to fast food
material and bottles which have a greater volume.
These items are often left behind by beachgoers
rather than deposited by the lake. The larger mate-
rial is generally removed by the city services or finds
its way in to the lake.
Upon observation the objects found appear to
represent the commercial activity in the area. The
frequency test confirms the observations for all
categories of trash related to food consummation.
Located adjacent to a supermarket, many restau-
rants and a busy pedestrian walkway; MRG and
MRD take either first or second position in all of
these categories. (fig 4)

16. Plastics are the most abundant material found at all sites
combined and all sites individually. Plastics take many
forms and it is often difficult to identify what the original
plastic pieces were or their function.
Of the thousands of pieces of plastic found and/or counted
on the five sites we were able to identify a few objects that
appear regularly and are not normally associated with ac-
tivities on the beach: cotton swabs, media filters and plastic
shotgun wadding. (image 14)
Media filters come from water treatment plants and indus-
tries that use a lot of water (fish farms and food process-
ing). Cotton swabs are flushed down toilets and end up
on our beach. Before arriving on our lakeshore, the plastic
shotgun wadding was inside a shotgun shell. The plastic
skirt separates the shot form the powder and is ejected
from the shotgun at the same time as the shot.

The exact geographic origin of these items is unknown,
but the frequency tests and inventories confirm the obser-
vations. These three items are found in either the top 10
of inventories, the top 10 of frequency or both. On any
beach in this study you have a 100% chance of finding
plastic, 68% chance of finding a cotton swab, 63% chance
of finding a media filter* and 56% chance of finding plastic
shotgun wadding.

17. Conclusion
The city services are very effective at reducing the volume of trash present on the
beach, but this only to a certain size. Nevertheless, the volume of trash that is left is
a concentration of bits of plastic, styrofoam, cotton swabs, cigarette butts and oth-
er unknown objects that put in doubt our image of a clean lake.
The concentration and placement of this trash in the strand line is concerning.
Whether it is a child playing on the beach or a swan digging for bread crumbs;
there can be no doubt that that they will come into contact with these items and
other unknown items that come to rest on our lake shore.
Removal of these pollutants is mandatory if we are to assure a safe environment
and reinforce our image of a “clean” country. The inventory and identification of
this trash gives us clues about where it comes from and the data collected can be
used to determine the density and frequency of the pollution.

Recommendation
The plagespropres.ch project should continue and be expanded to include all the
rivers in the communities of Vevey, La Tour-de-Peilz and Montreux. The emphasis
should remain on the elimination and identification of the trash collected. .
Possible evolutions
Regular water quality testing to inlcude testing for e-coli.
