<div dir="ltr" data-setdir="false">Definitely a possibility. But I think the numbers do indicate a recent spike in virus load in the wastewater. And a more recent decline.

And not without its flaws. </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">-- Bob Primak </div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><br></div><div><br></div>
