Two bills introduced this week would require mandatory lead testing at schools in California and Texas. House Bill 2395 was introduced by Rep. Nicole Collier, (D-Fort Worth), and would require the state’s 1,200 school districts and charters to pay for annual water supply testing, which is estimated to cost up to $3,000 per building, according to The Texas Tribune. Several Texas school districts have begun voluntarily testing their water, and replacing water fountains in some instances.
