Description
This indicator tracks the number of small on-site sewage systems (OSS) that have been properly inspected within the required state and local inspection schedules. OSS that are compliant with routine inspection schedules are less likely to negatively impact water quality and shellfish beds. This indicator can help us track the number of inspected systems that are compliant with state and local mandates which supports proactive assessment of pollution risks.
Progress Indicator Chart
In Puget Sound, fecal pollution impacts water quality, harvest ability and food safety of shellfish, and presence of viruses in swimming areas. Local health jurisdictions across the Puget Sound region work to educate and provide technical assistance to homeowners with onsite septic systems to prevent pollution concerns before they arise.
This Progress Indicator tracks the number of on-site sewage systems (OSS) that are compliant with their local inspection mandates. For all standard OSS designs, state code requires an inspection by a certified homeowner or professional every three years. For more complex OSS designs and/or OSS within environmentally sensitive areas, local codes may require an annual inspection by a certified homeowner or professional.
The data collected for this Progress Indicator illustrate progress in local health jurisdictions supporting the routine inspections of OSS within their jurisdictions. Routine inspections are a critical avenue through which OSS remain operational, thereby protecting environmental and public health.
This Progress Indicator is in development.
