.}rner winery -2- 5 November 1984 i During the inspection I detected a slight , offensive odor from the ponds . The odor could have been emanating from the feeder ditch since this appeared septic and black , whereas the ponds each contained about one foot of what appeared to be primarily stormwater . The ponds and berms appeared in good condition except for the fifth pond which is extremely overgrown . The present operations reportedly produce severe odors and may also be contributing pollution to ground water in the area . The following steps should be taken and/or problems resolved in order to solve these problems : 1 . Complete Vlastewater Characterization In order to make any design decisions for wastewater dis- posal , a complete wastewater characterization must first be performed . In addition to biological oxygen demand, flow, and total suspended solids , the characterization should also include nitrates , total nitrogen , phosphate , pH , total dissolved solids , and the carbon to nutrients ratio of the waste . our files do not show that any such characterization was done in either designing the present system or in requirements . drafting the present re q 2 . Design and Operation of Treatment Pond Facilities Treatment ponds must be designed with regard to both hy- draulic and organic loads. Waste characterization parameters as well as pond type (anaerobic , facultative , aerobic ) , depth to ground water , rainfall and runoff , necessity of liners , series or parallel operation , etc . , must be considered . Attention must also be given to solids removal , storage , and handling requirements when ponds are designed. It is not apparent that any of these parameters were considered in designing the present treatment pond facilities . 3 . Design and operation of Land Disposal Facilities Disposal of pond effluent onto land also requires design of facilities with regard to hydraulic and organic loads ( see Guidelines ) . soil types and permeabilities , depth to ground water , rainfall , slopes , etc . must be considered. opera- tional methods ( such as time between applications , the method of application , preparation and maintenance of the disposal fields , etc . ) must also be incorporated into the ultimate design . The present method utilized by Turner of pumping water onto surrounding fallow land takes none of this into account .
