Section 3 Inventory of Major WWTPs and Potential Industrial Reuse Demands Craddock Consulting Engineers 3-13 In Association with CDM & James Crook WWReuseTM1_Sec 3_final.doc Industries and Proximity to WWTPs Figure 3.9b presents the location of the industries and WWTPs in the Des Moines River watershed. Table 3.9c lists the various industries and their distance from the closer of the two WWTPs. The agricultural processing industries are all located within 3 miles of a WWTP. The Heron Lake WWTP is not shown because its design capacity of 0.1 mgd is less than 1 mgd. The ethanol plant and wastewater treatment plant modifications for Heron Lake will be investigated further in Task 2. One sand and gravel business is located about 4 miles from the Windom WWTP, while the other businesses are located more than 10 miles from a WWTP. Table 3.9c.

The water quality of the buried sand and gravel and Cretaceous aquifers often yield water of poor natural quality, typically high in sulfate and total dissolved solids. The highest yielding aquifers in this region are mostly narrow, channel outwash deposits which are susceptible to contamination, notably nitrates. Many residents rely on rural water supply systems because domestic wells are contaminated with nitrates. The area around Worthington and the central portion of the watershed is typically less susceptible to contamination than the other areas. Water quantity of appropriate quality has been an issue for potable water suppliers of this watershed. The cities of Luverne and Worthington, the Lincoln-Pipestone Rural Water System and Rock County Rural Water System are working with communities in South Dakota and Iowa to provide another source of water to the Des Moines and Missouri River watersheds in Minnesota’s borders: the Lewis and Clark Rural Water System.
