Dewatered Solids and Biosolids Allocations per Biosolids Management Practice Site

This dataset contains annual allocations of dewatered solids or biosolids from a specific dewatering facility to a specific management practice site in dry metric tons. 'Dewatered solids' are the solids remaining in digested sludge after removal of water in a dewatering facility. 'Biosolids', per the US Environmental Protection Agency (EPA), is treated sewage sludge that meets the EPA pollutant, pathogen & vector attraction requirements for land application and surface disposal, and the DEP has certified it with the EPA as such.

Biosolids in this case are also dewatered. Depending on the material being managed (i.e., dewatered solids or biosolids), a 'management practice site' may be one of the following: 1) a third party vendor treatment facility (e.g., composting, dryer, alkaline treatment) that converts the dewatered solids into biosolids for beneficial reuse in various land application practices (e.g., agricultural land application, reclamation site application) or for distribution/marketing as a soil amendment or fertilizer; 2) a direct land application site for agricultural use (typically a farm); or 3) a landfill. The dataset includes the pathogen (disease-causing organism) reduction and vector (an animal capable of transmitting disease such as flies or rodents) attraction reduction options employed as part of the treatment and the type of biosolids class produced, if applicable. There are different biosolids class types, each having specified treatment requirements for pollutants, pathogens and vector attraction reduction, as well as general requirements and management practices,

本数据集收录了特定脱水设施向特定管理实践场地年分配的脱水固体或生物污泥的量，单位为干公吨。所谓‘脱水固体’，系指在脱水设施去除水分后留在消化污泥中的固体物质。根据美国环境保护署（EPA）的定义，‘生物污泥’是指符合EPA污染物、病原体及病原媒介吸引力要求的处理过的污水污泥，且经纽约市环境保护局（DEP）认证符合此标准。在此情况下，生物污泥亦为脱水后的物质。根据所管理的材料类型（即脱水固体或生物污泥），‘管理实践场地’可能包括以下几种：1）第三方供应商处理设施（例如，堆肥化、干燥、碱性处理），将脱水固体转化为生物污泥，以实现其在多种土地利用实践中的有益利用（例如，农业土地利用、复垦场地应用）或作为土壤改良剂或肥料进行分销/营销；2）直接用于农业的土地应用场地（通常为农场）；或3）垃圾填埋场。数据集还包括作为处理一部分采用的病原体（致病原）减少和病原媒介（如苍蝇或啮齿动物，能传播疾病的动物）吸引力减少的选项，以及如适用的情况下产生的生物污泥类别类型。不同类别的生物污泥具有针对污染物、病原体和病原媒介吸引力减少的特定处理要求，以及一般要求和管理工作实践。有关生物污泥合规性、处理、用途和类别类型更多信息，请参阅：<a href="https://www.epa.gov/biosolids">https://www.epa.gov/biosolids</a>。
