Thank You!
BASIN was a community project which benefitted from over 1000 hours of
public volunteer time. BASIN was highlighted by the US EPA
in a national case study in its 2001 handbook Delivering Timely Environmental Information to Your Community.
Thank you to all volunteers, and especially to the late Jim Waterman, BASIN Project Coordinator!
