How CTTM Data Are Organized
Students collect CTTM data about buildings, taps, water chemistry and water quality using paper worksheets. They use different dataheets for different kinds of data. This post explains how the different datasheets relate to each other and will help teachers in organizing and overseeing the students’ work as they enter data. Students will use the following…
Public Water Systems in Maine
Maine is a rural state. Rather than having a few big city water systems, Mainers get their water from many small and mid-sized public systems in addition to private wells. In this post we provide information about the different kinds of public water systems that students will need as they map drinking water quality. Kinds…
Collecting CTTM Water Quality Data on Site
Crowd the Tap Maine builds a picture of water quality in an area by collecting samples from many different “taps,” or faucets. By collecting samples from many different taps, we can build a picture of what is happening in a water system. This post describes how collect information about a single tap. Students will collect…
