Industries and Proximity to WWTPs
The watershed inventory displayed in Figure 3.12c shows the WWTPs in relation to
the various industries in the watershed. The inventory shows that there are several
WWTPs with industries in close proximity and most of these are agricultural
processing industries. Examples include Seneca Foods in Glencoe, Burn Philip Food
Ingredients in Hutchinson, Northern Food & Dairy in Alexandria, all of which have
WWTPs within 1.5 miles of their operations. Table 3.12c lists industries within 4 miles
of a WWTP. The complete list of industries in the Mississippi River-Headwaters
watershed is in Appendix C.
