Bruce Lanphear, a professor at Simon Fraser University and also an expert in lead toxicity, said Edwards not only studies the impact of lead in water, but he makes his testing available to communities in need, like he did in Flint.
State legislators have approved $67 million in funding towards a total of $232 million recommended to provide ongoing support for Flint residents impacted by the city's water crisis. An additional $28 million was approved in January to offer lead testing, treatment and emergency services.
