### Everything Old is New Again

[R]egardless, the analysis has been done; lead remediation is still a screamingly good deal. Lead remains one of the most common and harmful pollutants in the country; it’s often present in old paint and settles into soil, particularly in urban areas. One comprehensive study concluded that “each dollar invested in lead paint hazard control results in a return of $17–$221.” And that study focused on current, laborious methods of lead remediation. As it happens, scientists have developed a new, cheaper method — mixing fish bones into soil (!) — to absorb lead and render it nontoxic. Pretty cool stuff. Imagine what more research and funding could do.
