The main issue against the use of biosolids on land application is whether it is safe for human consumption. Not the biosolids per se, but the produce and the crops that use it as organic fertilizer. This is an understandable concern from the communities that are exposed to biosolids, but fret not because there are ways on determining the safety and the “cleanliness” of biosolids as naturally organic fertilizer.
Source of the primary material
While it is hard to determine the source of the primary material from which the biosolids come from, you can actually monitor the production of biosolids in your community. By doing so, you can easily determine whether the primary source of the sewage sludge is from municipal waste and not industrial waste. Municipal waste consists of household waste that are less harmful to humans than waste produced by industries.
Treatments that the material underwent
There are different levels of treatments and processes that wastewater sludge needs to undergo. In order to fully understand the safety of the biosolids, you need to know how it was treated. This will also help you determine whether the classification of the biosolids is correctly interpreted. While biosolids originally bore pathogens and other harmful chemicals, the numerous treatments it underwent will generally “clean” it enough to be used for land and agricultural application.
Distribution of the biosolids
If something went wrong with the distribution of biosolids, it could contaminate what was originally a safe organic fertilizer. That is why it is better to purchase biosolids in bulk from treatment facilities in your locality. This will eliminate the fear of it being contaminated through the transportation method. Remember, that though biosolids have been treated again and again, there is a special need for its safe storage, transportation, and even application.
Regulations followed during processes and methods
The EPA is the regulating body for the production of biosolids. The guidelines produced by the EPA are posted on the internet for everyone to see. What anyone really needs is to just read about biosolids and the different treatment methods that it undergoes. Once there is a deeper understanding of these processes and the regulations that it is bound to, then we can make informed decision on the safety of biosolids for land and agricultural production, as well as for boosting the nutrients in the soil that produce crops, vegetation, and other kinds of food. Learn more about EPA regulations, and you’ll have a good idea if the biosolids in your locality are safe.
