What is it?

The Ottersampler is a small device that collects tiny water samples from your tap over time. This helps us understand how water quality can change from day to day or week to week.

What would I do?

1

Keep the sampler in your home during the sampling period.

2

When it is time to sample, fill a clean cup with tap water.

3

Place the tubing in the cup and press the button to collect the sample.

4

You may also answer a short survey and return the device at the end.

What do I get out of it?

  • Learn more about your tap water.
  • Help us understand how water quality changes over time.
  • Support community efforts to improve water access and information.
  • Help identify patterns that one-time testing might miss.

Good to know

  • The device is designed to be easy to use.
  • It collects small water samples over time.
  • The samples are tested later in a laboratory.
  • This project helps us better understand water at the tap.
