| Short Description |
A Class II Inspection was conducted at the city of Grandview Sewage Treatment Plant in October 1991. The treatment system includes a primary clarifier, lagoon system, and spray irrigation. The adequacy of treatment was difficult to assess; however, treatment across the lagoons did not appear to be good. Improved flow measurement at the plant is recommended.

| Abstract | Long Description |
A Class II Inspection was conducted at the city of Grandview Sewage Treatment Plant in October 1991. The treatment system includes a primary clarifier, lagoon system, and spray irrigation. The adequacy of treatment was difficult to assess; however, treatment across the lagoons did not appear to be good. Improved flow measurement at the plant is recommended. The facility's operation is periodically outside all of the State Waste Discharge Permit parameters. Significant laboratory deficiencies were identified. Ground water quality in the vicinity of the treatment lagoons appears degraded. Differentiation between ground water impacts due to the treatment plant, a nearby closed landfill, or other causes could not be made. A small wastewater discharge into the Yakima River was noted, although no indicators of gross contamination were observed in the river. The facility provided good avian and mammalian wildlife habitat. |
