*How can you tell whether your local water is safe for drinking or swimming?*
**Public Lab is working to make water quality information accessible for communities everywhere.** By designing a low-cost, ‘open source’ water quality monitoring platform that is easy to use, build, and maintain, we aim to enable communities to develop their own grassroots water quality monitoring networks and to assess common threats to local water quality -- like industrial pollution, coliform bacteria, road salt, and agriculture runoff.
Our aim is to **empower people with open source water quality tools**, so that:
- local residents can track changes in their drinking water quality using sensors that they build and use themselves;
- a home-grown early warning system could warn swimmers of high bacteria counts in urban watersheds;
- students could serve as stewards of their local river ecosystem by evaluating the impacts of climate change;
- researchers, water resource managers, and citizen scientists can easily and accessibly share water quality data.
Our project currently has **three main goals**:
### 1. An open source water quality sensor
We're developing a low-cost, open source hardware device that will measure some of the most common water quality parameters , using a design that makes it possible for anyone to build, modify, and deploy water quality sensors in their own neighborhood.
**Update! 1/27/14** -- First successful deployment of water probe in the Amethyst Brook in Amherst, MA:
