Heavy metals, volatile organic compounds, pesticides, herbicides, pharmaceuticals and microplastics pose a risk to our health.<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In December 2020, the European Parliament adopted the Drinking Water <\/span><a href=\"https:\/\/www.europarl.europa.eu\/spain\/es\/prensa\/communicados_de_prensa\/pr-2020\/12-2020\/acuerdo-para-mejorar-la-calidad-del-agua-del-grifo-y-reducir-la-basura-pl-stica.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Directive<\/span><\/a><span style=\"font-weight: 400;\"> to improve the quality of tap water and reduce the consumption of bottled water. This directive provided for the<\/span><b> imposition of stricter limits for certain contaminants, such as lead<\/b><span style=\"font-weight: 400;\">. It also envisaged the establishment of a list of substances or compounds of concern to the public and the scientific community for monitoring.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, the truth is that, <\/span><b>almost a year and a half later, the European Commission has still not drawn up this list<\/b><span style=\"font-weight: 400;\">, which should include pharmaceuticals, endocrine disruptors and microplastics that can damage our health.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It is still difficult to find colourless, odourless and tasteless tap water. In most cases, <\/span><b>tap water contains many substances, from the chlorine used to make it drinkable, which can give the water a characteristic bad taste, to more harmful substances such as heavy metals,<\/b><span style=\"font-weight: 400;\"> volatile organic compounds, pesticides, herbicides, pharmaceuticals, microplastics, bacteria and viruses.<\/span><\/p>\n<p><b>Routine controls only check the levels of those pollutants that are already legislated, but they are a small part<\/b><span style=\"font-weight: 400;\">. For example, the <\/span><a href=\"https:\/\/www.fresh-thoughts.eu\/userfiles\/file\/Pharma-2-Vidal.pdf\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Outbiotics<\/span><\/a><span style=\"font-weight: 400;\"> project, which is being developed in Catalonia, Aragon, Navarre, the Basque Country and the south of France, has found antibiotics such as amoxicillin, ciprofloxacin, enrofloxacin, azithromycin, sulfadiazine, sulfamethoxazole and trimethoprim in pre-drinking natural waters.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Studies such as the one published in the prestigious <\/span><a href=\"https:\/\/ehjournal.biomedcentral.com\/articles\/10.1186\/s12940-020-00591-0\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">journal<\/span><\/a><span style=\"font-weight: 400;\"> &#8216;Environmental Health&#8217; make clear the need to reduce perfluoroalkyl substances in tap water worldwide to improve our health, as they are considered endocrine disruptors.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h3><b>Persistent heavy metals<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Industrial and mining activity releases toxic metals such as <\/span><b>lead, mercury, cadmium, arsenic and chromium, which can reach aquifers and rivers<\/b><span style=\"font-weight: 400;\">, contaminating soil and accumulating in plants and organic tissues. Exposure to these elements is linked to health problems such as various types of cancer, kidney damage and developmental delays.<\/span><\/p>\n<p><b>Lead can also infiltrate drinking water through corrosion of service pipes<\/b><span style=\"font-weight: 400;\">, chrome-plated brass faucets and fixtures with lead solder.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The US Environmental Protection Agency (<\/span><a href=\"https:\/\/espanol.epa.gov\/espanol\/informacion-basica-sobre-el-plomo-en-el-agua-potable\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">EPA<\/span><\/a><span style=\"font-weight: 400;\">) determined that <\/span><b>the maximum level of this heavy metal in drinking water should be zero<\/b><span style=\"font-weight: 400;\">, &#8220;because lead is a toxic metal that can harm human health, even at low exposure levels&#8221; and can &#8220;bioaccumulate in the body over time&#8221;.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Children are particularly vulnerable to lead, as they absorb it more easily than adults and its renal elimination is less effective. Lead can affect their brain development, reduce their ability to concentrate and affect their academic performance.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h3><b>The invasion of microplastics<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A <\/span><a href=\"https:\/\/orbmedia.org\/the-invisibles?locale=es\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">study<\/span><\/a><span style=\"font-weight: 400;\"> conducted by the news organisation Orb Media in collaboration with researchers from the State University of New York and the University of Minnesota shows that <\/span><b>microplastics have been finding their way into tap water around the world for years<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Already, 83% of drinking water samples collected in five continents over the past decade contained microplastics. The United States had the highest contamination rate and, although Europe&#8217;s has the lowest, it had still very high (72%). <\/span><b>The average number of plastic fibres found in every 500 ml of water ranged from 4.8 in the US to 1.9 in Europe<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h3><b>Uncontrolled pesticides<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A recent <\/span><a href=\"https:\/\/www.ecologistasenaccion.org\/wp-content\/uploads\/2021\/10\/informe-contaminantes-agua-consumo-humano.pdf\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">report<\/span><\/a><span style=\"font-weight: 400;\"> by Ecologistas en Acci\u00f3n denounces the<\/span><b> poor control of chemical substances suspected of contaminating drinking water<\/b><span style=\"font-weight: 400;\">. This is the case with many pesticides, herbicides and biocides.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Sulphur, which is the most widely used in the countryside, has not been tested for in any of the water analyses carried out by Spanish municipalities in recent years. The same applies to substances as common in agriculture and livestock farming such as metam sodium (only one search was recorded in 2019), copper oxychloride, paradine oil, copper hydroxide and propamocarb.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition, <\/span><b>the report criticises the lack of a legal obligation to carry out complete analyses in small populations and their unreliability<\/b><span style=\"font-weight: 400;\"> due to the absence of quantified limits and the lack of accreditation of the contracted laboratories. This organisation has noted the absence of complete controls even in municipalities declared by the autonomous communities themselves as vulnerable to nitrates.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>If you want to discover how to drink the best water, save money and help the planet, go to <\/b><a href=\"https:\/\/www.11onze.cat\/en\/water-essentials\/\" target=\"_blank\" rel=\"noopener\"><b>11Onze Essentials<\/b><\/a><b>.<\/b><\/p>\n\n      <\/div>\n    <\/div>\n  <\/div>\n<\/div>\n\n\n<div class=\"component cards\">\n  <div class=\"container\">\n    <div class=\"row\">\n      <div class=\"col col-xl-8 offset-xl-2\">\n        <h1>If you liked this article, we recommend you read:<\/h1>\n        <div class=\"cards__wrapper\">\n          <div class=\"card\">\n            <a href=\"https:\/\/www.11onze.cat\/en\/magazine\/microplastics-find-way-into-bloodstream\/\" class=\"card-link\" target=\"_self\"><\/a>\n            <div class=\"card-img\">\n              <img decoding=\"async\" src=\"https:\/\/www.11onze.cat\/wp-content\/uploads\/2022\/04\/THUMBNAIL_MICROPLASTICS.jpg\" class=\"card-img-top\" alt=\"\">\n                <span class=\"card-category\">Sustainability<\/span>\n            <\/div>\n            <div class=\"card-body\">\n              <p class=\"card-title p2\"><strong>Microplastics in our bloodstream<\/strong><\/p>\n              <span class=\"card-time\">3 min read<\/span>\n              <p class=\"card-text small\">Scientific research has shown for the first time that microplastics<\/p>\n            <\/div>\n          <\/div>\n\n\n          <div class=\"card\">\n            <a href=\"https:\/\/www.11onze.cat\/en\/magazine\/plastics-choke-our-planet\/\" class=\"card-link\" target=\"_self\"><\/a>\n            <div class=\"card-img\">\n              <img decoding=\"async\" src=\"https:\/\/www.11onze.cat\/wp-content\/uploads\/2022\/03\/THUMBNAIL_PLASTICS_PRES_TERRA-2.jpg\" class=\"card-img-top\" alt=\"\">\n                <span class=\"card-category\">Sustainability<\/span>\n            <\/div>\n            <div class=\"card-body\">\n              <p class=\"card-title p2\"><strong>The plastics that choke our planet<\/strong><\/p>\n              <span class=\"card-time\">2 min read<\/span>\n              <p class=\"card-text small\">The millions of tons of plastic waste that we throw into the<\/p>\n            <\/div>\n          <\/div>\n\n\n          <div class=\"card\">\n            <a href=\"https:\/\/www.11onze.cat\/en\/magazine\/fight-against-plastic-oceans\/\" class=\"card-link\" target=\"_self\"><\/a>\n            <div class=\"card-img\">\n              <img decoding=\"async\" src=\"https:\/\/www.11onze.cat\/wp-content\/uploads\/2022\/03\/THUMBNAIL_PLASTICS_PRES_TERRA-1.jpg\" class=\"card-img-top\" alt=\"\">\n                <span class=\"card-category\">Sustainability<\/span>\n            <\/div>\n            <div class=\"card-body\">\n              <p class=\"card-title p2\"><strong>The fight against plastic oceans<\/strong><\/p>\n              <span class=\"card-time\">3 min read<\/span>\n              <p class=\"card-text small\">Plastic waste is already forming huge islands in the sea and has<\/p>\n            <\/div>\n          <\/div>\n\n              <\/div>\n              <br>\n              <br>\n              <div class=\"cards__wrapper\">\n\n        <\/div>\n      <\/div>\n    <\/div>\n  <\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":71,"featured_media":29817,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"content-type":"","footnotes":""},"categories":[1],"tags":[19],"class_list":["post-30035","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","tag-sustainability"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Is tap water healthy?
