One way to introduce new water stewards to water monitoring is through one-time, large-scale, \u201cblitz\u201d events. Earthwatch\u2019s FreshWater Watch programme includes a biannual \u2018Great UK WaterBlitz\u2019 event, where thousands of citizen scientists from across the U.K. collect samples over a four-day period. Citizen scientists are well positioned to capture data at a large spatial scale, and the first two Great UK WaterBlitz events Earthwatch Europe organised in June and September 2024, are great examples of a blitz event done well. With their simple testing protocol for nitrates and phosphates, mechanisms for distribution, and data analysis, they were able to compare nutrient pollution concentrations at the country, county and river basin levels, determining at a regional scale where future interventions might be needed.<\/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\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/earthwatch.org.uk\/wp-content\/uploads\/2024\/06\/Great-UK-WaterBlitz-report_June-2024_DIGITAL-SPREADS_LOW-RES.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Download the report<\/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 is-light vid-player has-primary-color has-text-color has-link-color\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-primary-background-color has-background-dim-0 has-background-dim\"><\/span><img decoding=\"async\" width=\"1175\" height=\"606\" class=\"wp-block-cover__image-background wp-image-484 lazyload\" alt=\"\" data-src=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-52-20.jpg\" data-object-fit=\"cover\" data-srcset=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-52-20.jpg 1175w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-52-20-640x330.jpg 640w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-52-20-1024x528.jpg 1024w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-52-20-768x396.jpg 768w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-52-20-50x26.jpg 50w\" data-sizes=\"(max-width: 1175px) 100vw, 1175px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1175px; --smush-placeholder-aspect-ratio: 1175\/606;\" \/><div class=\"wp-block-cover__inner-container is-layout-constrained wp-block-cover-is-layout-constrained\"> \n<div block-main-99a73f5ca1d36fad04d23759d780474c   class=\"block block-icons block-0 play\" id=\"block-main-99a73f5ca1d36fad04d23759d780474c\">\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=\"FreshWater Watch by Earthwatch Europe - Join the fight for healthy fresh water!\" width=\"500\" height=\"281\" data-src=\"https:\/\/www.youtube-nocookie.com\/embed\/-X8q_tw4sa0?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\">Our freshwater bodies are not adequately monitored across the UK.

In Henley-on-Thames, citizen scientists also collect data on E. coli levels, for example.&nbsp;Freshwater Watch data is also used to report on SDG 6.3.2 in partnership with the UN Global Environment Monitoring Systems.&nbsp;<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" width=\"862\" height=\"760\" data-src=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/map.jpg\" alt=\"Screenshot of map with thousands of markers on it, and  bar-charts showing how many samples read a certain amount for nitrates and phosphates.\" class=\"wp-image-482 lazyload\" style=\"--smush-placeholder-width: 862px; --smush-placeholder-aspect-ratio: 862\/760;width:612px;height:auto\" data-srcset=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/map.jpg 862w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/map-640x564.jpg 640w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/map-768x677.jpg 768w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/map-50x44.jpg 50w\" data-sizes=\"(max-width: 862px) 100vw, 862px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<div style=\"height:60px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"541\" height=\"412\" data-src=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-43-34.jpg\" alt=\"Photo of volunteers next to a river, reading the instructions\" class=\"wp-image-480 lazyload\" data-srcset=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-43-34.jpg 541w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-11-43-34-50x38.jpg 50w\" data-sizes=\"(max-width: 541px) 100vw, 541px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 541px; --smush-placeholder-aspect-ratio: 541\/412;\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\"><strong>Social<\/strong> value<\/h2>\n\n\n\n<p>The blitz format is a great way to engage those interested in water quality and want to make the next step in learning more while at the same time providing valuable data. Many monitoring programmes are long-term commitments and so offering a way for those looking to \u2018dip their toes\u2019 into water stewardship builds both interest and skills in growing their capacity for participating. Of Great UK WaterBlitz participants surveyed, 46% had no involvement in the environment prior to the blitz, 60% improved their understanding of water quality issues and 22% reported a positive shift In their relationship with nature. Further, testing at a national scale helps people zoom out to understand the larger context and see their role in working together.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-full is-style-circle-frame\"><img decoding=\"async\" width=\"671\" height=\"766\" data-src=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-12-00-29.jpg\" alt=\"Smiling volunteer holding two samples with their comparator.\" class=\"wp-image-492 lazyload\" data-srcset=\"https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-12-00-29.jpg 671w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-12-00-29-640x731.jpg 640w, https:\/\/castco.org\/wp-content\/uploads\/2024\/10\/Screenshot-on-2024-10-03-at-12-00-29-44x50.jpg 44w\" data-sizes=\"(max-width: 671px) 100vw, 671px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 671px; --smush-placeholder-aspect-ratio: 671\/766;\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<h2 class=\"wp-block-heading\">Demonstrating <strong>CaSTCo principles<\/strong><\/h2>\n\n\n\n<p>While many have conducted localized blitzes, Earthwatch\u2019s Great UK WaterBlitz is innovative in that they were able to fundraise for supplies, design a programme that could be executed remotely and independently, and coordinate across the entire UK.<\/p>\n\n\n\n<p>The entire programme also shows how powerful a unified and simple protocol can be in engaging widely.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\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<div class=\"wp-block-cover is-light fifty-vw-cover\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim-0 has-background-dim\" style=\"background-color:#707664\"><\/span><img decoding=\"async\" width=\"546\" height=\"403\" class=\"wp-block-cover__image-background wp-image-479 lazyload\" alt=\"Man with two young boys.
