This publication covers microfiltration, which is used for physical removal of contaminants from water. It describes how these processes work, their situation-specific usefulness/applications, maintenance needed for their proper functioning, and guidance for the consumers to select the appropriate filter.
Lime mud is a by-product produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to convert the sodium carbonate back to sodium hydroxide in order to use it again. In the process, calcium carbonate is formed.
This bulletin provides the general public a quick reference for some commonly used standards for metal concentrations in biosolids and various by-products intended for land application. Most of the standards presented here are regulatory; however, we have also included information on average metal concentrations in agricultural soils.
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of more than 9,000 manmade chemicals that have been in use worldwide since 1940, primarily in industry and numerous commercial and consumer products. The widespread use of PFAS for the past several decades has raised concerns due to their persistence, bioaccumulative nature, and potential adverse health effects. This publication provides information about the background, uses, and environmental and human health consequences of PFAS chemicals, as well as the EPA’s primary drinking water regulation standards and water treatment systems for removal/reduction of these chemicals from drinking water. Testing options and PFAS monitoring efforts by the Georgia EPD are included along with references for further reading.
Cover crops have many benefits for farmers, including erosion control, weed suppression, and feeding the food soil web. Cover crops also play an important role in fertility, particularly for nitrogen.
One of the challenges facing farmers who use cover crops is quantifying the available nitrogen supplies to the following cash crop by the decomposing cover crop residues and how they might change their fertilizer management to account for this. This publication is intended to educate farmers on the nitrogen cycle, cover crops, and nitrogen; how nitrogen is released from cover crops; and the new Cover Crop Nitrogen Availability Calculator, including the steps necessary to use the Calculator.

When examining horses for conformation, either when considering a purchase or competing in horse judging contests, it is important to break things down into key principles to avoid becoming overwhelmed when putting the overall picture together. There are five main criteria to evaluate when examining a horse’s conformation: balance, structural correctness, way of going, muscling, and breed/sex character (also known as type). This publication describes each of these criteria in detail.
