🎈 Public Lab: Revisions for 'Mystic River'

Revisions for Mystic River

71	donblair	January 17, 2014 22:52 \| almost 11 years ago [Main image above is by Suzanne McDaniel, and was taken at Island End River in Chelsea, MA, part of the Mystic River watershed. Suzanne's photo was one of the winners of the MyRWA photo contest.] Background The Mystic River in Massachusetts flows from the Mystic Lakes in Winchester and Arlington, through Medford, Somerville, Everett, Charlestown and Chelsea, and into Boston Harbor, and has supported a long history of economic progress in one of the most densely populated urban areas of New England. Today, the Mystic faces serious water quality problems, shared by urban water bodies around the world: pollution from leaky sewer pipes, waste disposal sites; excessive nutrients and discharges of raw sewage; fuel hydrocarbons; and road salt. Portions of the watershed often fail to meet state bacteria standards for swimming and boating, and its Alewife Brook subwatershed is one of the most contaminated water bodies in Boston. The Mystic River watershed received a ‘D’ from the US EPA on its 2012 water quality report card. Several organizations are engaged in water monitoring projects for the Mystic, but the high cost and ‘closed data’ nature of current technology severely limits the scope of current efforts, and makes data sharing difficult. The Public Lab community, by designing a low-cost, ‘open source’ water quality monitor that is easy to build and maintain, hopes to greatly expand the scope of current monitoring efforts, and to enable communities to develop their own grassroots monitoring networks. This page is a description of Public Lab's efforts to develop low-cost open hardware tools for assessing water quality in the Mystic River watershed. IOBY Campaign Public Lab is partnering with IOBY to develop a low-cost water quality monitoring network for the Mystic River. Here's the crowd-funding campaign, which ends February 14th: Mystic River Open Water IOBY Campaign Water Quality Monitor Prototypes Our main focus at first is on developing open hardware alternatives to the current most common water quality monitoring sensors, which measure temperature, conductivity, and water depth. Tracking temperature over time at several locations along a river allows researchers to detect unusual trends in river water temperature -- this might help locate pollution sources along the river, and helps assess whether the water temperature is amenable to fish. Conductivity is a useful measure for a variety of water quality issues, including excess salinity (usuall due to road salt), dissolved solids, and other sources of water pollution. Measuring water depth along with these other parameters allows researchers to correlate temperature and conductivity with storm events -- helping to determine the relative contribution of stormwater runoff and combined sewer overflow events to changes in river water quality. Our initial goal is to develop open source, low-cost dataloggers that measure these various parameters over time, storing data on board the datalogger, with batteries that last for several months. Volunteers will then build and deploy these sensors at various locations in the watershed, and go out to collect data from them (using laptops) months afterwards, submitting the data to an online data repository. We'll be collaborating with MyRWA and Plymouth State, who already have citizen science volunteer networks who have been using a similar approach, but who previously needed to rely on much more expensive devices with encrypted data formats. This low-cost, open approach will allow the volunteer community to collaboratively build, maintain, and improve the sensor technology they'll be using, and share the resultant data among themselves as well as with researchers and water resource managers. We're currently basing our data logger prototype on an open source hardware project: the "mchck" -- an inexpensive, low-power microcontroller design with on-board flash memory, and 'real time clock'. This means that it can function as a low-cost, long-lasting datalogger. Our fork of the mchck project is here, with datalogger functionality implemented here. The "water quality shield" we're developing for the mchck will include hardware for measuring conductivity, temperature, and water depth is here. Here are some nice D3 libraries that might be useful. STE(A)M Curricula As we develop a water quality open hardware platform, our hope is to incorporate this same technology in middle school and high school environmental science programs. We've partnered with Plymouth State and the Amherst Middle School to explore the best ways of doing this. The Amherst Middle School has already developed water quality curricula that involved deploying sensors in the Fort River in Amherst, MA, but the proprietary, encrypted data nature of the sensors they were using made progress difficult. We'll be leveraging the curriculum materials they've already built in order to develop online, open source water quality curricula that educators everywhere can contribute to and share. The focus will be developing a comprehensive STEAM approach -- Science, Technology, Arts, and Mathematics -- of the sort pioneered by RISD; allowing students to design their own visualizations and interpretations of the environmental data that they collect themselves. Online Visualization of Water Quality Data We're going to be working with Patrick Herron, Mark Green, Jeff walker, and Mary Martin to find accessible and compelling ways of displaying water quality data online. For use in prototyping our online visualization system, Mary Martin has provided a link to real-time river depth and precipitation informationfrom the Hubbard Brook Ecosystem Study in New Hampshire. Their current visualization is here. Patrick Herron has provided a dataset that is a single sensor reading from a polluted waterway on the Alewife Brook, here: ALB006.txt Jeff Walker has already developed code for visualizing streamflow csv data using D3, based on a D3 reusable chart pattern. Pictures A design for a 3D printable plug that will nicely contain the sensor electronics, and hold the conductivity wires in place.

Our initial goal is to develop open source, low-cost dataloggers that measure these various parameters over time, storing data on board the datalogger, with batteries that last for several months. Volunteers will then build and deploy these sensors at various locations in the watershed, and go out to collect data from them (using laptops) months afterwards, submitting the data to an online data repository. We'll be collaborating with MyRWA and Plymouth State, who already have citizen science volunteer networks who have been using a similar approach, but who previously needed to rely on much more expensive devices with encrypted data formats. This low-cost, open approach will allow the volunteer community to collaboratively build, maintain, and improve the sensor technology they'll be using, and share the resultant data among themselves as well as with researchers and water resource managers. We're currently basing our data logger prototype on an open source hardware project: the "mchck" -- an inexpensive, low-power microcontroller design with on-board flash memory, and 'real time clock'. This means that it can function as a low-cost, long-lasting datalogger. Our fork of the mchck project is here, with datalogger functionality implemented here. The "water quality shield" we're developing for the mchck will include hardware for measuring conductivity, temperature, and water depth is here. STE(A)M Curricula As we develop a water quality open hardware platform, our hope is to incorporate this same technology in middle school and high school environmental science programs. We've partnered with Plymouth State and the Amherst Middle School to explore the best ways of doing this. The Amherst Middle School has already developed water quality curricula that involved deploying sensors in the Fort River in Amherst, MA, but the proprietary, encrypted data nature of the sensors they were using made progress difficult. We'll be leveraging the curriculum materials they've already built in order to develop online, open source water quality curricula that educators everywhere can contribute to and share. The focus will be developing a comprehensive STEAM approach -- Science, Technology, Arts, and Mathematics -- of the sort pioneered by RISD; allowing students to design their own visualizations and interpretations of the environmental data that they collect themselves. Online Visualization of Water Quality Data We're going to be working with Patrick Herron, Mark Green, Jeff walker, and Mary Martin to find accessible and compelling ways of displaying water quality data online. For use in prototyping our online visualization system, Mary Martin has provided a link to real-time river depth and precipitation information from the Hubbard Brook Ecosystem Study in New Hampshire. Their current visualization of live data is here. Patrick Herron has provided a dataset that is a single sensor reading from a polluted waterway on the Alewife Brook, here: ALB006.txt Jeff Walker has already developed code for visualizing streamflow csv data using D3, based on a D3 reusable chart pattern.

Suzanne's photo was one of the winners of the MyRWA photo contest.] Background The Mystic River in Massachusetts flows from the Mystic Lakes in Winchester and Arlington, through Medford, Somerville, Everett, Charlestown and Chelsea, and into Boston Harbor, and has supported a long history of economic progress in one of the most densely populated urban areas of New England. Today, the Mystic faces serious water quality problems, shared by urban water bodies around the world: pollution from leaky sewer pipes, waste disposal sites; excessive nutrients and discharges of raw sewage; fuel hydrocarbons; and road salt. Portions of the watershed often fail to meet state bacteria standards for swimming and boating, and its Alewife Brook subwatershed is one of the most contaminated water bodies in Boston. The Mystic River watershed received a ‘D’ from the US EPA on its 2012 water quality report card. Several organizations are engaged in water monitoring projects for the Mystic, but the high cost and ‘closed data’ nature of current technology severely limits the scope of current efforts, and makes data sharing difficult. The Public Lab community, by designing a low-cost, ‘open source’ water quality monitor that is easy to build and maintain, hopes to greatly expand the scope of current monitoring efforts, and to enable communities to develop their own grassroots monitoring networks. This page is a description of Public Lab's efforts to develop low-cost open hardware tools for assessing water quality in the Mystic River watershed. IOBY Campaign Public Lab is partnering with IOBY to develop a low-cost water quality monitoring network for the Mystic River. Here's the crowd-funding campaign, which ends February 14th: Mystic River Open Water IOBY Campaign Water Quality Monitor Prototypes Our main focus at first is on developing open hardware alternatives to the current most common water quality monitoring sensors, which measure temperature, conductivity, and water depth. Tracking temperature over time at several locations along a river allows researchers to detect unusual trends in river water temperature -- this might help locate pollution sources along the river, and helps assess whether the water temperature is amenable to fish.

We'll be collaborating with MyRWA and Plymouth State, who already have citizen science volunteer networks who have been using a similar approach, but who previously needed to rely on much more expensive devices with encrypted data formats. This low-cost, open approach will allow the volunteer community to collaboratively build, maintain, and improve the sensor technology they'll be using, and share the resultant data among themselves as well as with researchers and water resource managers. We're currently basing our data logger prototype on an open source hardware project: the "mchck" -- an inexpensive, low-power microcontroller design with on-board flash memory, and 'real time clock'. This means that it can function as a low-cost, long-lasting datalogger. Our fork of the mchck project is here, with datalogger functionality implemented here. The "water quality shield" we're developing for the mchck that will include hardware for measuring conductivity, temperature, and water depth is here.

Suzanne's photo was one of the winners of the MyRWA photo contest.] Background The Mystic River in Massachusetts flows from the Mystic Lakes in Winchester and Arlington, through Medford, Somerville, Everett, Charlestown and Chelsea, and into Boston Harbor, and has supported a long history of economic progress in one of the most densely populated urban areas of New England. Today, the Mystic faces serious water quality problems, shared by urban water bodies around the world: pollution from leaky sewer pipes, waste disposal sites; excessive nutrients and discharges of raw sewage; fuel hydrocarbons; and road salt. Portions of the watershed often fail to meet state bacteria standards for swimming and boating, and its Alewife Brook subwatershed is one of the most contaminated water bodies in Boston. The Mystic River watershed received a ‘D’ from the US EPA on its 2012 water quality report card. Several organizations are engaged in water monitoring projects for the Mystic, but the high cost and ‘closed data’ nature of current technology severely limits the scope of current efforts, and makes data sharing difficult. The Public Lab community, by designing a low-cost, ‘open source’ water quality monitor that is easy to build and maintain, hopes to greatly expand the scope of current monitoring efforts, and to enable communities to develop their own grassroots monitoring networks. This page is a description of Public Lab's efforts to develop low-cost open hardware tools for assessing water quality in the Mystic River watershed. IOBY Campaign Public Lab is partnering with IOBY to develop a low-cost water quality monitoring network for the Mystic River. Here's the crowd-funding campaign, which ends February 14th: Mystic River Open Water IOBY Campaign Water Quality Monitor Prototypes Our main focus at first is on developing open hardware alternatives to the current most common water quality monitoring sensors, which measure temperature, conductivity, and water depth. Tracking temperature over time at several locations along a river allows researchers to detect unusual trends in river water temperature -- this might help locate pollution sources along the river, and helps assess whether the water temperature is amenable to fish. Conductivity is a useful measure for a variety of water quality issues, including excess salinity (usuall due to road salt), dissolved solids, and other sources of water pollution. Measuring water depth along with these other parameters allows researchers to correlate temperature and conductivity with storm events -- helping to determine the relative contribution of stormwater runoff and combined sewer overflow events to changes in river water quality. We're currently basing our data logger prototype on an amazing open source hardware project: the "mchck" -- an inexpensive, low-power microcontroller design with on-board flash memory, and 'real time clock'. This means that it can function as a low-cost, long-lasting datalogger. Our fork of the mchck project is here, with datalogger functionality implemented here.
