  2. 2. Cordova Creek activity report - January 2016 - gary@hammerdirt.ch - www.plagespropres.ch About hammerdirt About this project Hammerdirt is a nonprofit associ- ation with no political or religious affiliations. We are driven by our desire to create an environment that leverages technology and citizen participation to solve prob- lems now and in the future. We prefer action to words and our projects reflect this philosophy. Collaborative by nature we active- ly seek feedback from all interest- ed parties and we integrate that feed back into our operations. The project is based on a statistical approach and requires data collec- tion regularly and systematically. In order to establish a trend, the data collected must have temporal, quantitative and geographical pa- rameters. Once collected, the data can be used to evaluate the effectivenes of lit- ter mitigation strategies. The data is compared over time, to demon- strate the evolution of the quantity and type of litter found at precise locations. We use an international standard developed by the EU and UNEP for categorizing the litter found during a litter-survey . Our data is compat- ible with the Marine Litter Watch program. Our method is simple : 1.Separate material into categories 2.Count each item in each category 3.Record quantities 4.Photograph 5.Dispose of material We have refined our methods and we use common technologies to minimize administrative overhead. Data entry is completed on site and is immediately exploitable. The method

Foam, candy wrappers, shop- ping bags and bits of plastic make up 42% of the items found. The average increased steadily for the period, terminating at 227.4 pcs. A 38.7% increase for the period. figure 1 Foam 16% Candy wrappers 15% Shopping bags 6% Bits of plastic 5% Remains of plastic bags 4% Cigarette butts 3% All the rest 51% Compositionof trashfoundin CordovaCreek 12/08/2015 - 01/27/2016 The rise in quantity of litter found at the site is accompanied by a greater variety of litter found. For the period Nov 24 - Dec 13 2015 the litter found rep- resented 66 categories. In this report we identified 80 different categories, 74 categories combine to make up 51% of the litter found. figure 2 figure 2 figure 1 Location GPS Area Cumulative total Start date Last inventory Cordova Creek 38.60198033 -121.31710535 285m² 1819 pieces 11/28/2015 1/27/2016
  5. 5. Cordova Creek activity report - January 2016 - gary@hammerdirt.ch - www.plagespropres.ch Foam as % of daily to- tal oscillates between 5 and 25%. The greatest variance of all items in the survey. Candy wrappers oscil- late between 10 and 20%, shopping bags between 3 and 12%. Identifying and elim- inating the source of these items may be a focal point of litter mitigation strategies. figure 3 0,0% 10,0% 20,0% 30,0% 40,0% 50,0% 60,0% 70,0% 80,0% 90,0% 28.11.2015 02.12.2015 08.12.2015 13.12.2015 06.01.2016 13.01.2016 20.01.2016 27.01.2016 Percentageofdailytotal All plastics and all food related items as % of daily total 12/08/2015- 01/27/2016 Cordova Creek %Plastic %Food related items For the period, plastics (as a group) are 79% of the material found. Food related items combine to make up 32.1% of the trash found, almost half of that is candy wrappers and associated snack items. It seems appropriate that targeting areas where food/snack items are sold could have significant impact in reducing the trash found. figure 4 figure 4 figure 3 0,0% 5,0% 10,0% 15,0% 20,0% 25,0% 30,0% 28.11.2015 02.12.2015 08.12.2015 13.12.2015 06.01.2016 13.01.2016 20.01.2016 27.01.2016 Foam, candy wrappers and shopping bags as a % of daily total 12/08/2015- 01/27/2016 Cordova Creek Foam Candy Wrappers Shopping bags

The debris has an easy access to the creek. figure 6 Encouraging residents to close the dumpster lids, mov- ing the dumpsters away from the creek, adding additional dumpsters or creating a more secure barrier are all options that may reduce the amount of trash in the creek.
