33 Q. When we are land applying biosolids for more than 2 days in a row, why are we required to collect daily biosolids samples for percent total solids even though we have a percent total solids value on the sample we analyzed for metals?Q. When we are land applying biosolids for more than 2 days in a row, why are we required to collect daily biosolids samples for percent total solids even though we have a percent total solids value on the sample we analyzed for metals? A. When the land application period lasts for more than 2 consecutive days, the DEQ has found that the percent solids analysis provided on the analytical report for metals and nutrients is often not representative of the percent total solids of biosolids actually land applied. Because R (1) requires that a person collect and analyze representative samples, the DEQ typically does require daily percent total solids analysis, unless information can be provided demonstrating that the initial data is representative (i.e., mechanical plant with good mixing). The daily percent solids results should be utilized when calculating daily application rates and reporting dry tons land applied.A.

The daily percent solids results should be utilized when calculating daily application rates and reporting dry tons land applied. A related issue regarding lagoon cleaning projects is that the composite samples collected for the RMP approval often overestimate the concentration of available nutrients and underestimate the total percent solids of the biosolids being applied to land after a few days of cleaning operations inside the lagoon. This phenomenon is likely due to the mixing of the biosolids with the clay particles from upper portions of clay liners disrupted from equipment working inside the lagoon. To address this situation and provide the most representative data possible (in addition to the sampling for metals, nutrients, and fecal coliform prior to beginning the project), the DEQ have begun requiring the sample plan in the lagoon RMP to include a commitment to analyze a minimum of 2 additional composite samples for available nutrients in addition to the daily percent solids collected during the course of the lagoon cleaning. This data should then be used in reporting dry tons and nutrients land applied.A related issue regarding lagoon cleaning projects is that the composite samples collected for the RMP approval often overestimate the concentration of available nutrients and underestimate the total percent solids of the biosolids being applied to land after a few days of cleaning operations inside the lagoon.
