According to Iowa DNR’s assessment/listing methodology, as data age beyond 10 years, they are no longer considered appropriate for characterizing current water quality conditions. The assessment of support of the Class B(WW1) aquatic life uses is changed from “fully supported” to “not assessed” due to the age of the water quality data (greater than 10 years) upon which the original assessment was based. Although the DNR assessment/listing methodology requires at least 10 samples collected over a three-year period in order to develop a "monitored" assessment appropriate for Section 303(d) listing, the numbers of samples at Volga River stations 34 and 35 (nine samples at both stations) are considered sufficient to justify this impairment. coli is greater than the state criterion of 126 orgs/100 ml., the primary contact recreation uses should be assessed as "partially supported" (see pgs 3-33 to 3-35of U.S.
EPA guidelines for Section 305(b) reporting, if the geometric mean of E. Both of these geometric means exceed the Iowa Class A1 criterion of 126 orgs/100 ml.
coli for the nine samples collected at Volga River station 35 was 276 orgs/100 ml the geometric mean for the nine samples collected at Volga River station 304 was 245 orgs/100 ml. coli orgs/100ml, thus suggesting continued impairment of the Class A1 uses in this segment of the Volga River.
coli) at both Volga River monitoring stations in 2001 exceeded in exceeded the Iowa Class A1 water quality criterion of 126 E. The geometric mean level of indicator bacteria (E. Because the primary Section 303(d) impairment identified for the 2006 assessment/listing cycle (indicator bacteria) is addressed by the TMDL, this waterbody was moved from IR Category 5a from the 2004 assessment/listing cycle to IR Category 4a (impaired TMDL approved) for the 2006 cycle this waterbody remains in IR Category 4a.ĮXPLANATION: The Class A1 (primary contact recreation) uses remain assessed (evaluated) as "partially" due to high levels of indicator bacteria. Note: A TMDL for pathogen indicators in this segment of the Volga River was prepared by DNR and approved by EPA in 2006. Despite the age of the data used for this assessment, the impairment of the Class A1 uses remains until more recent data suggest a good cause for de-listing. The water quality data upon which these assessments are based are now more 10 years old. The source of data for this assessment remains the results of IDNR/UHL monthly monitoring conducted from March to November, 2001, near Osborne (Site 34) and Volga (Site 35) in support of TMDL development for this river segment. Fish consumption uses remain "not assessed" due to the lack of recent fish contaminant monitoring in this river segment. The Class B(WW1) aquatic life uses are considered “not assessed” (IR 3a) due to the lack of recent water quality data upon which to base an assessment. These outdoors activities are available in and near Volga River State Park.SUMMARY: The Class A1 (primary contact recreation) uses remain assessed (evaluated) as "not supported" (IR 4a) based on levels of indicator bacteria that violate state water quality standards.
