About Us

We are a dedicated group of scientists and professionals that take pride in collecting and analyzing quality data to develop a more complete understanding of the hydrogeologic system in the upper basin of the Santa Margarita Watershed as an aid in achieving an amicable resolution of the present water-rights controversy without resorting to expensive litigation encompassing both the surface-water and ground-water systems in the upper basin.
