Last fall, months before San Diego Unified School District began testing all schools’ drinking water for lead, it did a special round of tests a Sunset View Elementary in Point Loma. The district found lead but didn’t tell parents. Rather, it told one parent – the one who’d requested a lead test.

Aside from big questions surrounding whether SANDAG’s proposed sales tax increase will generate the amount the agency says it will, opponents point to other promises they think could go unfulfilled — like whether SANDAG will complete the highest-priority projects within 15 years, whether it will use local labor and whether the measure will do anything to improve water quality.
