The sewer system and the storm water drainage system are
completely separate in Lexington. Older systems in some other
communities are still partially combined. However, even in
Lexington, there are some people that illegally connect their sump
pumps to their toilets and the Town's sewer system.<br>

<div>There is a big problem with this data being compared
over long periods of time</div>
<div>Some of the waste water includes surface run-off and
some mostly doesn't</div>
<div>hence, since the y axis is a concentration of virus
in the water -- if the amount of "active water" from
households is diluted by surface run-off because of
recent rain or even more complicating melting snow mixed
with recent rain -- how can you tell?</div>
<div><br>
</div>
<div>I suggest that the data suggests that last year there
was a real spike and that recently there is just "noise"
in the system</div>
