title: 'Rainwater quality testing with Isla Urbana'
description: "Rainwater is relatively free of impurities except for those pollutants from the atmosphere that settle on the roof, organic matter and bird and animal droppings entering the system, and possible pollutants from system materials. 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. The health risks posed by different elements entering rainwater can be minimized by good design and maintenance practices. 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's systems. This is one project in a series of water quality and community service projects at Isla Urbana."
