A group of Roger Ludlowe Middle School students, parents and staff will stage a walk-a-thon Sunday, March 27, to raise money to help provide clean water for people in three poor countries.

The Walk for World Water is planned from noon to 4 p.m. at the Ludlowe High School track.

The middle school group -- Ludlowe Corp. -- is raising money in conjunction with Humanity Now Inc. and will be walking laps around the track.

The group still is seeking pledges from the community. The walk this year will benefit communities in Senegal, Ecuador, and Haiti.

To raise awareness of the cause, Ludlowe Corp. students have been going about town demonstrating the use of a water filter -- the type they plan to help provide to people in needy nations. The students put dirty snow in a bucket, and when it is melted, ran it through a filter that traps all impurities. Then they drank the fresh water.

The walkathon is planned as a family event, and they typically bring food, listen to music and play games. Parent Julie Vanderblue said no donation is too small.
