In Mexico City there are probably more risks from using municipal supply water rather then rainwater, nevertheless it is still important to measure the water quality coming from [[rainwater harvesting]] systems.\n\nThe health risks posed by different elements entering rainwater can be minimized by good design and maintenance practices.<ref>World Health Organization. Water Sanitation and Hygiene: 6.11 Rainwater harvesting. http://www.who.int/water_sanitation_health/gdwqrevision/rainwater.pdf</ref> [[Isla Urbana]] wants to test their rain water quality for domestic uses and the following are parameters, EPA and WHO recommended concentration levels, testing procedures, and results found by [[Isla Urbana|Isla urbana's]] systems. This is one project in a series of water quality and community service projects at [[Isla Urbana]].\n\n== Background ==\n\n[[File:Logo-Isla-urbana-facebook-2dark.jpg|thumb]]\n\nTesting is being done by the Laboratorio de Ajusco de Tecnologia Alternativa, a nonprofit laboratory providing technical assistance in testing different [[appropriate technologies]]. Right now they are working with [[Isla Urbana]] for rainwater quality testing and the [[International Renewable Resources Institute-Mexico]] for biodigester effluence water and fertilizer quality studies. [[Isla Urbana]] is a nonprofit working in as well as in other areas of [[Mexico]] to improve [[water quality]] and water accessibility to people who have no access to clean water. They coordinate efforts with different communities to build local capacity and local jobs for designing and building rainwater catchment systems around Mexico.\n\n== Rainwater harvesting system ==\n\n{{Excerpt|Rainwater harvesting system and component water quality analysis in the field with Isla Urbana}}\n\n== Testing Procedures for Rainwater quality ==\n\n{{Excerpt|Rainwater Quality Testing Procedures at Isla Urbana and Ajusco Labs}}\n\n== Expected Parameter Concentrations for Rainwater ==\n\n{{Excerpt|Parameters for rainwater quality testing at Isla Urbana and the Ajusco Lab}}\n\n== Testing potability of rainwater after boiling ==\n\n{{Excerpt|Testing potability of rainwater after boiling at Isla Urbana and Ajusco Labs}}\n\n== Testing synthesized components of rainwater harvesting systems ==\n\n{{Excerpt|Testing synthesized components of rainwater harvesting systems with Isla Urbana}}\n\n== References ==\n\n<references />\n\n{{Page data\n| license = CC-BY-SA-3.0\n| keywords = rainwater, water, water quality, project testing\n| sdg = SDG06 Clean water and sanitation\n| organizations = Isla Urbana\n}}\n\n[[Category:Mexico City|Mexico City]]\n[[Category:Rainwater]]\n[[Category:Water]]\n[[Category:Water quality]]\n[[Category:Project testing]]"}
