The document discusses household sewage treatment systems and their impact on stormwater pollution. It provides an overview of Franklin County and township stormwater programs, which work to comply with EPA permits and protect water quality. The programs identify and eliminate failing household sewage systems, which can contaminate drinking water and pose health risks if untreated sewage is discharged. The cleanup process will take years to investigate highest risk areas and help homeowners repair or replace failing systems.

56. How We Summarized Health Risks? Franklin County Public Health and Franklin Soil and Water Conservation District have created a ranked list of “Identified Areas of Concern.” The following metrics were used within a GIS to identify and rank these Areas of Concern. - Dry Weather Screening Results - Locations of HSTS - Population/Building Density

57. Dry Weather Screening Density Variable

58. Dry Weather Screening Density Variable - ENLARGEMENT -

59. Population / Building Density Variable

60. HSTS Density Variable

61. Summarizing Variables DWS Density HSTS Density Population / Housing Density Numerical values assigned to density layers. Typical for each layer produced 0 4 6 5 3 2 1

62. Highest Ranking Areas Extracted / Highlighted 3 Variables Summarized
