Hard water is water that has high mineral content. Usually this is cause by water passing through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. These are all essential minerals for humans so from that perspective we are fortunate if we have hard tap water. But not everything about hard water is good as you will see below.<\/p>\n\n\n\n

How is water hardness measured?<\/h2>\n\n\n\n

Classification<\/td>	mg CaCO3 \/ L<\/td>	Hardness in ppm<\/td>	Hardness in \u00b0fH<\/em> (F)<\/td><\/tr>
Soft<\/td>	0-60<\/td>	0-60<\/td>	0-6.0<\/td><\/tr>
Moderately Hard<\/td>	61-120<\/td>	61-120<\/td>	6.1-12.0<\/td><\/tr>

In contrast, drinking water hardness in Spain ranges from 15 to 1000 ppm.<\/p>\n\n\n\n What are the negative aspects of hard water?<\/h2>\n\n\n\n Water with high levels of hardness may be frustrating when you wash your hands as it can stop a soapy lather forming. Very hard water might also have a salty taste. Hard water can create other issues, such as imparting an unusual flavour in tea and causing a build-up of scale minerals in hot water appliances and water pipes.<\/p>\n\n\n\n Another issue seldom talked about is that hard water combined with chlorine causes poor taste. This is why the tap water along the coasts in Spain<\/a> including Barcelona<\/a>, Valencia, Alicante<\/a>, Murcia and Malaga<\/a> have such poor tasting tap water.<\/p>\n\n\n\n Thankfully this is easy to fix with a high quality water filter such as TAPP<\/a> that will remove the limescale<\/a>.<\/p>\n\n\n\n Hardest water in Spain<\/h2>\n\n\n\n What is the highest water hardness reported in Spain by the water companies? We checked our database to find our and the top 3 is.<\/p>\n\n\n\n Ja\u00e9n 600<\/li> Ciudad Real 600<\/li> Barcelona<\/a> 580 <\/li><\/ol>\n\n\n\n Note: Unit is in mg CaNO3\/L or ppm and water hardness varies during the year so may change by us much as 300 ppm between highest and lowest measurement.<\/em><\/p>\n\n\n\n Softest water in Spain<\/h2>\n\n\n\n This is a slightly more challenging question as many water providers simply state that the water hardness is soft or below a value of 50 ppm. But among the softest water we found in our study the top 3 were:<\/p>\n\n\n\n Avila 50<\/li> Madrid<\/a> 50<\/li> Segovia 50<\/li><\/ol>\n\n\n\n Note: Unit is in mg CaNO3\/L or ppm and water hardness varies during the year so may increase at times.<\/em><\/p>\n\n\n\n Water hardness and limescale<\/h2>\n\n\n\n One of the biggest challenges with hard water is that it often causes limescale. This is the white stuff that forms in the tea kettle, coffee machine, dishwasher, washing machine, glasses, around the faucet and many other places. Scientifically there is nothing dangerous in limescale in terms of your health but it can be really annoying. Despite this there are many common myths that hard water and limescale causes kidney stones and other health related issues.<\/p>\n\n\n\n To get rid of limescale<\/a> from tap water use a special water filter<\/a> such as TAPP that breaks down and remove the limescale.<\/p>\n\n\n\n Summary<\/h2>\n\n\n\n To find out more about the water hardness where you live visit water.backup.tappwater.comm<\/a>. <\/p>\n\n\n\n Sources<\/h2>\n\n\n\n https:\/\/www.livescience.com\/54521-tap-water-tastes.html<\/a> – why does my water taste weird?<\/p>\n\n\n\n Water quality reports for:<\/p>\n\n\n\n Madrid<\/a> Barcelona <\/a>Valencia Girona Seville Zaragoza M\u00e1laga<\/a> Murcia Casco Urbano Palma de Mallorca <\/a>Bilbao Alicante<\/a> C\u00f3rdoba Valladolid Gij\u00f3n L’hospitalet de Llobregat A Coru\u00f1a Vitoria-Gasteiz Granada Elche Oviedo Santa Cruz de Tenerife <\/a>Badalona Cartagena Terrassa M\u00f3stoles Jerez de la Frontera Sabadell Alcal\u00e1 de Henares Fuenlabrada Legan\u00e9s Almer\u00eda Getafe Castell\u00f3n de la Plana Burgos Alcorc\u00f3n Albacete Salamanca Logro\u00f1o San Crist\u00f3bal de La Laguna Huelva Tarragona Lleida Marbella Le\u00f3n Dos Hermanas Torrej\u00f3n de Ardoz Parla Matar\u00f3 C\u00e1diz Santa Coloma de Cervello Santa Coloma de Gramenet Alcobendas Ja\u00e9n Reus San Fernando C\u00e1ceres Las Rozas Roquetas de Mar Lorca San Sebastian de los Reyes Cornella de Llobregat Rivas-Vaciamadrid Pozuelo de Alarc\u00f3n Guadalajara Toledo Chiclana de la Frontera San Baudilio de Llobregat Torrevieja Mijas Torrente Coslada Coslada V\u00e9lez-M\u00e1laga Arona Fuengirola Palencia Manresa Orihuela Valdemoro Alcal\u00e1 de Guada\u00edra Ciudad Real Majadahonda Paterna Torremolinos Benidorm Sanl\u00facar de Barrameda Benalm\u00e1dena Villanueva y Geltr\u00fa Castelldefels Estepona Viladecans Sagunto Ponferrada El Prat de Llobregat Collado Villalba Zamora Aranjuez M\u00e9rida Alcoy San Vicente del Raspeig \u00c1vila Linares Sarda\u00f1ola del Vall\u00e9s Arganda del Rey Cuenca Adeje Elda Molins de Rei Villarreal Colmenar Viejo Utrera Calvi\u00e1 Granadilla de Abona Rinc\u00f3n de la Victoria Puertollano Rincon de la Victoria Esplugues de LLobregat Gava Vich Mairena del Alcor Sant Feliu de Llobregat Mislata Alhaur\u00edn de la Torre Aldaya La Rinconada Marrach\u00ed San Adri\u00e1n de Bes\u00f3s Lluchmayor Montcada i Reixac Petrer Sant Joan Despi Manises Coria del R\u00edo Arcos de la Frontera Burjasot Alacu\u00e1s Rota El Campello Catarroja Sant Adria de Besos Camas C\u00e1rtama Paiporta Adra Alboraia Armilla Barbate Maracena Moncada San Juan de Aznalfarache Las Gabias Picasent Alfafar Alfara del Patriarca Marchena La Zubia Albolote Silla Atarfe Sant Just Desvern Begues Churriana de la Vega Santa Fe Benet\u00faser Og\u00edjares Santa Mar\u00eda del Camino Godella Montgat Hu\u00e9tor Vega Alcal\u00e1 del R\u00edo La Carlota Puebla del R\u00edo Pica\u00f1a Palleja Peligros Andrach Vegas del Genil Meliana Sedav\u00ed La Mojonera Algarrobo Agost Aguas de Busot Albalat dels Sorells Albuixech Alc\u00e1cer Alfocea Alm\u00e1cera Beniparrell Bonrep\u00f3s y Mirambell Bu\u00f1ola Busot Cerdanyola del Valles Chirivella Cuart de Poblet El Garrobo El Papiol El Puig Emperador Esporlas Foyos Garrapinillos Jijona Lugar Nuevo de la Corona Masalfasar Masamagrell Masanasa Monforde del Sid Muchamiel Museros Pe\u00f1aflor Puebla de Farnals Puerto Venecia Puigpu\u00f1ent Puzol Rafelbu\u00f1ol Rocafort San Antonio de Benag\u00e9ber San Juan de Alicante<\/p>\n","protected":false},"excerpt":{"rendered":" What is the water hardness in Spain?
