The Iowa Clean Water State Revolving Fund (CWSRF), established by the Clean Water Act, is a federal assistance program primarily administered by the states. While currently 94 percent of the loan dollars nationally are used for publicly owned wastewater facilities (Section 212 or “point source” projects), states may also fund nonpoint source pollution control (Section 319) and estuary protection (Section 320) projects (USEPA, 2012). Seventeen states have provided some level of funding for soil erosion control and manure management practices for nonpoint source water quality protection.
