They set out protocols that allowed community monitoring to be rigorous and non-confrontational, pin-pointing the pollution source and remedying the issue. Norfolk Rivers Trust\u2019s volunteer coordinator organised and empowered the volunteers to test weekly before and after the location and before and after the solution was implemented. <\/p>\n\n\n\n<p><a id=\"_msocom_1\"><\/a><\/p>\n\n\n\n<p>Together, the partners also validated the accuracy of the monitoring tools and implemented one of the first versions of a pollution reporting program and volunteer data platform to support the EA, prototyping many new ways for effective integration between community, environmental non-profits, government, and community. &nbsp;<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-outline is-style-outline--1\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/norfolkriverstrust.org\/project\/castco\/\">Find out more<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<div class=\"wp-block-cover vid-player has-primary-color has-text-color has-link-color\"><img decoding=\"async\" width=\"1143\" height=\"595\" class=\"wp-block-cover__image-background wp-image-803 lazyload\" alt=\"\" data-src=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-23-140044.png\" data-object-fit=\"cover\" data-srcset=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-23-140044.png 1143w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-23-140044-640x333.png 640w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-23-140044-1024x533.png 1024w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-23-140044-768x400.png 768w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-2024-10-23-140044-50x26.png 50w\" data-sizes=\"(max-width: 1143px) 100vw, 1143px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1143px; --smush-placeholder-aspect-ratio: 1143\/595;\" \/><span aria-hidden=\"true\" class=\"wp-block-cover__background has-primary-background-color has-background-dim-0 has-background-dim\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-block-cover-is-layout-constrained\"> \n<div block-main-560dc4b8441c0fbdae3d83f0113104b0   class=\"block block-icons block-0 play\" id=\"block-main-560dc4b8441c0fbdae3d83f0113104b0\">\n    <svg class=\"icon icon-play\" role=\"presentation\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 71.71 71.71\"><desc>play<\/desc><circle cx=\"35.86\" cy=\"35.85\" r=\"35.86\" fill=\"currentColor\"\/><path fill=\"#fff\" d=\"M29.86 22.41c.63.04 1.24.27 1.74.66l16 10.99c1 .5 1.4 1.72.89 2.72-.19.38-.51.7-.89.89l-16 10.98c-.5.4-1.11.63-1.74.65-1.15 0-2.07-.94-2.07-2.09 0-.07 0-.13.01-.2v-22.3c-.12-1.14.71-2.17 1.85-2.29.07 0 .14-.01.21-.01z\"\/><\/svg>\n<\/div>\n\n\n<!DOCTYPE html PUBLIC \"-\/\/W3C\/\/DTD HTML 4.0 Transitional\/\/EN\" \"http:\/\/www.w3.org\/TR\/REC-html40\/loose.dtd\">\n<html><body><figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"embed-container\"><iframe title=\"CaSTCo: Collaboration in Action\" width=\"500\" height=\"281\" data-src=\"https:\/\/www.youtube-nocookie.com\/embed\/vI4mssXrydQ?feature=oembed&amp;enablejsapi=1&amp;rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" class=\"lazyload\" data-load-mode=\"1\"><\/iframe><\/div>\n<\/div><\/figure>\n<\/body><\/html>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group no-margin has-bg-alt-2-background-color has-background is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading has-text-align-center\">The <strong>context<\/strong><\/h2>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-container-core-group-is-layout-b0c428d9 wp-block-group-is-layout-constrained\">\n<p class=\"has-text-align-center has-medium-font-size\">On the River Tat, the Environment Agency monitoring point downstream was failing its waterbody target for phosphate.

Sometimes, it\u2019s simple: Once you have the data, a simple investigation and intervention can remedy a chronic or acute issue. <\/p>\n\n\n\n<p>This case study led to the collaborative development of the Wensum citizen science pollution reporting framework with the EA CS coordinator and local EA Land &amp; Water Team.
