Some of my friends are in Flint and I'm horrified by their situation. I would like to learn how to test for lead independently.
After all if you can't trust the state sending them water to test is not sufficient. The testing procedures I have read about give too many type II errors. A procedure with a bias toward type I errors would be better since then I could pay a professional lab to see if it was real.
For tests that only detect high levels of lead, could they be made more sensitive by evaporating the water then testing a larger sample?
