Micro to Macro Water Pollution

Elevator Pitch

Background Information

Hammerdirt came to the BIO-DESIGN for the REAL WORLD's Winter School with data on the macropollutants washing up on the local beaches in and around Montreux (CH). The data format conforms to international norms, and over two years, some patterns can be observed in the level of litter on the shores. The collaboration will be an exchange and complement to what is already on-going at Hammerdirt.
The presentation can be found here:How we can work together

Aims

To answer: Does the presence of macropollutants on the shores of Lac Leman correlate with micropollutants (biological, chemical, particulate, etc.) in the lake water?

Brainstorm Results

brainstorm board

At Open Hackuarium #88, we came up with some initial ideas.

• Data Analysis

• Image analysis and machine learning to readily tabulate the macro-pollutants collected on the beach
• synching the above data with a phone application in the internationally accepted format
• Add lake existing data (lake current, meterology, etc.)

• Water collection and Analysis

• Standardizing Collection Methods
• Water chemistry testing - turbidity, pO2, pH, conductivity, temperature
• DIY free NH2
• Microparticle counting - DIY
• Heavy metal analysis DIY equipment of BIODESIGN to be more robust - or
• Make a fluorescent plate reader for higher throughput (CAUTION: still need P1 to use bioreporters here)
• antibiotic resistant bacteria (CAUTION: we cannot amplify/concentrate possible pathogens)
• Fish diseases - ask Maison de la Rivière?

• Awareness Raising - Recycling

• Recycle plastics using the extruder and use it to 3D print objects
• Biodegradation with mycelium

Water Quality and Analysis

Spring and Summer 2016

Introduction

One of the benefits of a “Community Based Environmental Monitoring” (CBEM) project is to expand the monitoring capacity of government agencies and engage the public in environmental stewardship. (1) (2) In response to questions from the public and our own professional curiosity we have decided to initiate a limited CBEM project.

As part of the Montreux Clean Beach Project II(MCBPII), a water quality testing (WQT) program is being initiated at selected sites of the MCBPII. Symptoms reported by members and frequent bathers in the lake during previous summer seasons have sometimes been attributed to low bathing water quality, influenced by increased anthropogenic pressure of lakefront activities during certain times of the year. This year's WQT aims to gather microbiological data over a six week period in order to test this hypothesis.

Meetings at “La Maison de la Rivière” and the “Institut National de Recherche Agronomique” support the idea that the WQT information proposed is not regularly collected at the Haut-Lac locations covered by the MCBPII.

Objectives

CBEM programs are designed to educate the public, involve local citizens in environmental stewardship and provide reliable data for government and other interested organizations. In this regard the MCBPII CBEM program is no different than that of any other existing project. (3) (2) (4)
Specifically, the goals for this project are to:

1. Collect reliable water quality data as defined by the World Water Monitoring Challenge (5)
2. Collect and enumerate the quantity of key bacteriological indicators, in particular those related to fecal contamination (6)
3. Increase the skills of hammerdirt staff in regards to collecting and processing water samples.
4. Make the obtained data free and open to use for all concerned
5. Inform the public about affordable and simple water monitoring techniques
6. Inform the public of community based resources designed to advance scientific literacy

Deliverables

The objectives of a CBEM are designed to increase the monitoring capacity of current public systems and provide reliable, accessible data for the public and other government researchers. Data gathered from this project will be reported with our regular activity reports and the raw data will be available for download within 72 hours of the testing date from our repository on Github or through the KoboToolbox for the location in question. This document along with sampling protocols and all other supporting documents will be available on the wiki.

Weekly results will be furnished to the CIPEL, SIGE and INRA:

1. Location and number of tests
2. Results of tests completed for the week

An end of project report will be published in PDF format, available for interested parties, and include:

1. Summary statistics and findings
2. Graphs/plots
3. Map overlay with densities and values
4. Comparison with government supplied data (if available)
5. Discussion of limitations and possible improvements to future CBEM projects

Testing Materials

Turbidity, temp, DO and PH

Testing materials and supplies will be procured from the World Water Monitoring Challenge an international program managed by the International Water Association and the Water Environment Federation.
Assembled and sold by Lamotte company as a “basic test kit,” each kit includes one set of hardware and enough reagents to conduct up to 50 rounds of testing for pH, dissolved oxygen, temperature, and turbidity. Included are:

1. Instruction booklet (5)
2. Sample collection jar
3. PH test tube
4. Dissolved oxygen vial
5. Secchi disk decal
6. Temperature strips (14-40°C and 0-12°C)
7. 50 pH reagent tablets (enough for 50 tests)
8. 100 Dissolved oxygen reagent tablets (enough for 50 tests)
9. Color chart for d etermining DO, pH and turbidity test results

Microbiological Analyses

Presence and quantity of E.coli, other coli forms, Salmonella and Aeromonas will be tested using ECA Check Easygel. Easygel was first approved for Water Watch volunteer monitoring programs in the USA in 1999. A study released in 2009 compared the results of “Easygel” and “3M Petrifilm” used by volunteers to the results of laboratory analysis. Both methods had an overall accuracy rate above 80%. (7) (8) One big benefit of the Easygel format is that environmental samples of up to 5ml can be readily plated, with no worries about having to melt (and cool down!) agarose as used in standard microbial plates.

Members of the Hackuarium laboratory have used “Easygel” in previous educational activities, thus facilitating the training of hammedirt staff and volunteers.

Agree on documentation and collaboration tools

• Internal communication - hackuarium slack
• Calendar? - we have a biodesign google calendar
• Protocols - [1]?
• Electronic Lab Notebook - [2]? - a template system where people can write down what they do would be nice, should it be the same as the Data entry format where you comment on unusual procedures or events?
• Data entry and sharing - Hammerdirt github, compliance with the international standards

Coliform Bacteria Counting

---

Coliform bacteria is an indirect indication of fecal contamination of the waters. There are several methods to distinguish coliform bacteria vs other microorganisms that may grow on an agar plate.

Easy Gel

Micrology Labs Coliscan Easygel

• Rachel asked for an offer including shipping and the 15% discount for the a coliform bacteria testing medium.
• reminder request sent again 18 April to Jonathan Roth (CEO of Micrology Labs) and Doug Wengerd (who eventually answers notes to their 'info' address)

Protocol from the Micrology Labs

To note: the Micrology Lab ECA Easygel plates are more expensive, but can assay up to 5ml of sampled water per plate for ready scoring and disposal. Another currently proposed plate media would not only be less discriminating, but require more equipment for the sterile setup and final cleanup, and probably only allow 0.5ml to be assayed/plate.

Other Media

• Endo agar where gram negatives are favored to grow. Fermentation of lactose in the medium by coliform bacteria gives metallic green sheen to those colonies.
• MacConkey agar - also contains lactose and neutral red as a pH indicator, bile salts to inhibit gram-positive bacteria growth
• MacConkey agar with sorbitol is used to isolate E. coli O157, a pathogenic enteric bacteria
• Eosin Methylene Blue agar - Lactose fermenting bacteria turn a dark color, gram positive bacteria also inhibited

Automatic Colony Counter and Plate Counting

This is not a DIY gel, but ENDO agar was used for the workshops Lifepatch conducted in Indonesia: Quantification of e. coli contamination in water
From Lifepatch, we have set this up DIY automatic colony counter.

Other Methods

• Good "travaux pratique" protocol for bacterial counting and salts concentration from Bioutils, UNIGE
  
• Other protocol proposing several direct and indirect methods
  

Biodesign has tried:

• Hack-a-Taq
• This early post has a pdf at the end summarizing techniques, including portable sensor, paper strip, etc.

Scaling

Basic calculation for cost for one time analysis:

number of plates = number of sites x number of dilutions x number of replicates + positive control + negative control

Use glass petri-dishes for recycling - we can as Lifepatch how they set it up.

Community Bioreporter Kit for Switzerland

---

• Our current prototype needs to be field-ready - the final design parameters need to be discussed.
• The protocol for the bioreporter assay needs to be simplified.

Otherwise, the system for working with the bioreporters has been approved with the Swiss authorities.
