Water can sometimes contain unhealthy levels of hazardous substances. Many locations have experienced an increased potency of aluminum, which alters the pH levels of water and results in non-potable water. Although traces of substances can be harmless or even beneficial, water must be monitored for optimal wellness. My design solution is a detector that mimics aspects of the hydrangea flower to determine if a water supply is safe by using color-changing aluminum and acidic detection. Loose aluminum ions bond to different compounds to create alternate colors; thus the hydrangea-based pH tester provides an easy and reusable way to for people in underdeveloped countries to test for potable water.
