This article takes a deep dive into sewage sludge. Sewage sludge is the 1% remains from wastewater treatments, also known as biosolids, it is the stuff that isn’t water and cannot be treated. Sewage sludge causes pollution due to many harmful elements being present. It discusses ways sewage sludge is dealt with, for example, thickening, dewatering, anaerobic digestion etc. Furthermore, on average in America a person will produce .16 pounds of sludge a day. Pennsylvania’s population of 12 million will produce approximately 300,000 pounds of sewage sludge a year. Sewage sludge needs a resting place after it is treated, top places where sludge is moved to are landfills, incineration, and land application which looks to reuse the sludge because it does have nutrients. Lastly it discusses regulations and laws related to land application with sewage sludge. 

This article connects to environmental science because it takes an effect of wastewater management and dives into how we are using it to help the environment and minimize the negative effects of it. The idea of land application with sewage sludge is massive. Taking what seems to be a harmful biosolid and feeding it back into our earth in a healthy way is phenomenal. Wastewater management has been a hit in terms of the health of our environment. Since sewage sludge treatment installations started happening in the 50’s and 60’s the country’s rivers and streams  have been thriving. Americans and people all across the world used to dump the sewage sludge into our waters, it got to a point where the water was overwhelmed and the health took a massive dip. Ultimately wastewater management and sewage sludge management are making our lives better and the environment healthier.
