The map link still works but the map is 10x better than when this post was written.  All data and news wells have been updated in 2025.]<\/p>\n\n\n\n<p>Welcome to RMP\u2019s new Generation 2 map of the Ann Arbor Dioxane 1,4 Plume.&nbsp; This is RMP\u2019s first Gen2 map and is a leap forward in RMP\u2019s environmental mapping software and it&#8217;s free to use for anybody with an internet connection.<\/p>\n\n\n\n<p class=\"has-text-align-center\"><a rel=\"noreferrer noopener\" href=\"https:\/\/www.respectmyplanet.org\/public_html\/mi_09_ann_arbor\" target=\"_blank\" aria-label=\"CLICK HERE TO OPEN THE MAP IN NEW WINDOW, THEN BOOKMARK IT IN YOUR FAVORITES (opens in a new tab)\">CLICK HERE TO OPEN THE MAP IN NEW WINDOW, THEN BOOKMARK IT IN YOUR FAVORITES<\/a><\/p>\n\n\n\n<p><\/p>\n\n\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/Qy4E2PMV1HU\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n\n\n<p>Watch the video above to get an overview of how our new map works.&nbsp;

This URL will never change.&nbsp;&nbsp; When you load the map, you will be centered over Ann Arbor Michigan and you will see four distinct Dioxane 1,4 contamination plumes, the groundwater prohibition zone (dashed red line), and 464 unique points of interest (markers) that are all clickable to get more information.&nbsp; Depending on when you read this post, more markers may have been added.&nbsp; This map will always be evolving as new data becomes available but the mechanics of how simple the map is to use will never change.<\/p>\n\n\n\n<p>Arrow #2 \u2013 Click on the \u201cSlide\u201d tab on the left hand side of your screen to slide out the control panel to get access to four different panels that each provide more information about the map.&nbsp; Go ahead and click on the slide button and then we will take a look at each of the four control panels.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Control Panel &#8211; Marker Info<\/h2>\n\n\n\n<p>Arrow #3 \u2013 There are four buttons that each represent a different panel of data.&nbsp; When you first slide out the control panel, the \u201cMarker Info\u201d panel is highlighted.&nbsp; Clicking on the \u201cMarker Groupings\u201d button, \u201cLegend\u201d button, or \u201cData Query\u201d button will open a different panel.&nbsp; Each panel will be briefly described throughout this post.&nbsp; The \u201cMarker Info\u201d panel shows a listing of all the 464 markers on the map along with their respective name, latest parts per billion Dioxane 1,4 value from the most recent sampling data, and an \u201cinfo\u201d icon.&nbsp; If you click on the \u201cinfo\u201d icon, it will open that marker\u2019s info window on the map.<\/p>\n\n\n\n<p>Arrow #4 \u2013 The \u201cAMW-1\u201d well is randomly selected here.&nbsp; If you click on the \u201cinfo\u201d icon next to this well, it will open that well\u2019s info window as seen in Arrow #5.&nbsp; The map has been zoomed in a little bit so you can see this well a little closer up.&nbsp; You can zoom in or out to your heart\u2019s content like you would using any Google map.<\/p>\n\n\n\n<p>Arrow #5 \u2013 This is the info window for the AMW-1 well which happens to be a monitoring well which is colored white with the letters \u201cMW\u201d on it (more on the different well types later).&nbsp; In the infowindow, you can see a little more information about the well plus you can see exactly where that marker is on the map.&nbsp; In the case of the AMW-1 well you can see it\u2019s last sample date was Sept 12, 2018 &amp; its last sample reading was 320ppb of Dioxane 1,4.&nbsp;&nbsp; You\u2019ll also notice there is a link in the info window for this location\u2019s homepage.&nbsp; Each well has its own home page.&nbsp; If you click on the \u201chomepage\u201d hyperlink, it will open the location\u2019s homepage where you can learn more information about that location.&nbsp; We will take a look at an example of a well\u2019s location homepage later.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Control Panel &#8211; Marker Groupings<\/h2>\n\n\n\n<p>Arrow #6 \u2013 Click on the \u201cMarker Groupings\u201d button to display the marker groupings panel.&nbsp; You can see whichever button you click becomes highlighted.&nbsp; In this panel, you can hide &amp; unhide markers by type.&nbsp; This powerful feature allows you to see the map from different perspectives.<\/p>\n\n\n\n<p>Arrow #7 \u2013 By selecting or deselecting different marker groups, you can see different features.&nbsp; Perhaps you only want to see Extraction Wells or only monitoring wells, just select &amp; deselect markers by group here.&nbsp; In this screenshot, Monitoring Wells &amp; Residential wells are not visible.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Control Panel &#8211; Map Legend<\/h2>\n\n\n\n<p>Arrow #8 \u2013 If you click on the \u201cMap Legend\u201d button, you\u2019ll see the listing of different plumes &amp; the marker types.&nbsp; The Map Legend shows the descriptor colors for the contamination by parts per billion.&nbsp; The plumes are easiest to see if you hide all the markers from the \u201cMarker Groupings\u201d tab so you can see just the plumes.&nbsp;&nbsp; The plume data points come from SRSW and the colors are 20% opacity so each \u201cplume within a plume\u201d looks darker.&nbsp; So the darker the color, the more contaminated that area.&nbsp; The outer plume is the extent of the plume and the red dashed line is the groundwater prohibition zone. &nbsp;&nbsp;You can scroll down the panel to see all the different plumes &amp; the description of the markers.<\/p>\n\n\n\n<p>Data Query \u2013 The data query section is something under construction but this is going to be where you can query different views of the map.&nbsp; For example \u201cshow me all the sites with Dioxane 1,4 greater than 1000ppb\u201d or \u201cshow me all locations sampled in the last 365 days\u201d.&nbsp; The data is available for these queries but it takes time and money to set up new &amp; exciting features.&nbsp; Please consider making a tax deductible donation <a rel=\"noreferrer noopener\" href=\"https:\/\/www.paypal.com\/donate\/?token=mGS6t17Z_p_HjrHa9DaVGjtIdt3admDNTr1nG4vCaM92ORSAYJIZAQPBudoJxdZxLr7aJG&amp;country.x=US&amp;locale.x=US\" target=\"_blank\" aria-label=\"by clicking here (opens in a new tab)\">by clicking here<\/a> so RMP can hire more labor to keep writing the code for the coolest &amp;

Every single location (i.e. map marker) has its own location homepage where you can drill down to get more information about that location.&nbsp; In the example pictured, you can see the extraction well TW-8.&nbsp; Below are a few of the many things you can learn about this particular location:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Who drilled the well:&nbsp;&nbsp; Stearns<\/li>\n\n\n\n<li>How many times has the water been sampled at this location:&nbsp;&nbsp; 269 times<\/li>\n\n\n\n<li>How deep is the top of the well screen:&nbsp; 59.5 feet<\/li>\n\n\n\n<li>How deep is the bottom of the well screen:&nbsp;&nbsp; 69.5 feet<\/li>\n\n\n\n<li>When was this location\u2019s water sampled last:&nbsp;&nbsp; November 9, 2018<\/li>\n\n\n\n<li>What was the last sample\u2019s Dioxane 1,4 content:&nbsp; 730ppb<\/li>\n<\/ul>\n\n\n\n<p>You can click on any other location to find similar information.&nbsp; RMP\u2019s software will retrieve the data from the EGLE data sources provided to the public.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where Does The Data Come From:<\/h2>\n\n\n\n<p>RMP gets our data from the <a href=\"https:\/\/www.michigan.gov\/egle\/0,9429,7-135-3311_4109_9846-71595--,00.html\">Gelman Sciences, Inc. Site of Contamination Information Page<\/a> hosted by Michigan\u2019s EGLE.&nbsp; The polygon\u2019s for the contamination plumes come from the <a href=\"https:\/\/sites.google.com\/site\/srsworg\/\">SRSW \u2013 Scio Residents For Safe Water<\/a> web page.<\/p>\n\n\n\n<p>The bulk of the data from EGLE comes in the form of a Microsoft Access database found at the link above.&nbsp; Within the database, there are two key tables that RMP uses to make this map:&nbsp; the \u201cwells\u201d table and the \u201cdata\u201d table.&nbsp;&nbsp; The \u201cwells\u201d table lists over 700 unique locations but only the approximately 460 locations have XY coordinates that can be converted to latitudes &amp; longitudes.&nbsp; Those locations in the wells table represent the markers you see on the map.&nbsp; The locations without coordinates cannot be displayed.&nbsp; The \u201cdata\u201d table has approximately 50,000 records and is always expanding as new samples are taken.&nbsp;&nbsp; The \u201cdata\u201d table allows RMP to relate the well name to the sampling data and display each location\u2019s history of sampling.<\/p>\n\n\n\n<p>The data related to the Gelman Dioxane Contamination Plume has been accumulated over decades and costs associated with collecting &amp; compiling the data are anyone&#8217;s guess but certainly some multiple of million dollars.&nbsp; The same data is available to everyone for review through the EGLE website.&nbsp; What sets RMP apart from other organizations is our software.&nbsp; RMP\u2019s software connects all of EGLE\u2019s data to a Google map and allows anyone with an internet connection to interact with the data in a way that has never been done before.&nbsp;&nbsp; You don\u2019t need expensive ARCGIS software.&nbsp;&nbsp; You don\u2019t need to install Google Earth and load KML files.&nbsp;&nbsp; You no longer have to be relegated to the pdf &amp; jpg images you see in newspaper articles where it\u2019s hard to see what you\u2019re looking for.&nbsp; All you need is an internet browser &amp; an internet connection and you can zoom in &amp; out on all the available data points and see decades worth of sampling history in an easy to use format. And, if your budget is like ours, more great news: our maps will always be free to the public.<\/p>\n\n\n\n<p>RMP\u2019s Gelman Dioxane 1,4 Plume Map is a demonstration map of our software.&nbsp; RMP has gigabytes of other data from Michigan\u2019s EGLE that we would like to put into our new Generation 2 mapping software.&nbsp;&nbsp; RMP plans to map the Wurtsmith Airforce Base #PFAS contamination, the Back Forty Goldmine on the Menominee River, the Zephyr Petroleum Storage Tank contamination in Muskegon, the Wickes TCE Contamination Plume in Antrim county, dioxin contamination in the Upper Tittabawassee floodplains of Midland downstream from Dow Chemical, and many more.&nbsp;&nbsp; There are many map applications out there but none are as easy &amp; fast as RMP\u2019s regular old Google map using Google\u2019s powerful &amp; fast servers.&nbsp;<\/p>\n\n\n\n<p>RMP is a Michigan based 501(c)3 organization with annual revenues on average of under $100 dollars.\u00a0 Everything you see on this website is a result of volunteer effort and good software.\u00a0 We need money now to make it to the next level of bringing the best software in front of more people.\u00a0 RMP believes we can teach more children &amp; more adults about environmental sciences, water protection, and sustainable energy because our software is more powerful than what any other environmental organization has.\u00a0 Look at what you can do with this one demonstration map.\u00a0 People with no knowledge of the extent of the Ann Arbor Gelman Dioxane Plume can learn as much as any expert in no time flat by using our software &amp; website.\u00a0 Teachers can teach students in their classrooms and show them real data that tax payers have spent millions of dollars on over the decades.\u00a0 RMP\u2019s software brings very valuable data sets to life in an organized, easy to use, and fast application that allows anyone to learn what is going on and where.\u00a0\u00a0 Would you please consider making a tax deductible donation to RMP by <a href=\"https:\/\/www.paypal.com\/donate\/?cmd=_s-xclick&amp;hosted_button_id=QGM8GBL3F8K5E&amp;ssrt=1773421754552\" target=\"_blank\" rel=\"noreferrer noopener\">clicking here<\/a> to use our secure PayPal page.\u00a0 You donation will help us get good reliable information to more people across Michigan and around the world.\u00a0 Thank you so much for your support.<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-center\"><a href=\"https:\/\/www.paypal.com\/donate\/?cmd=_s-xclick&amp;hosted_button_id=QGM8GBL3F8K5E&amp;ssrt=1773421754552\" target=\"_blank\" rel=\"noreferrer noopener\">PLEASE MAKE A TAX DEDUCTIBLE DONATION TO OUR 501(c)3 NON-PROFIT ORGANIZATION BY CLICKING HERE<\/a><\/h4>\n","protected":false},"excerpt":{"rendered":"<p>RMP has just launched our first Generation 2 Google Map featuring the Gelman Dioxane 1,4 Plume in Ann Arbor, Michigan.
