Why Clay Has High Aquifer Porosity But Low Permeability
03/07/25
“Why does clay have high porosity but low permeability?”
Clay has a highly porous structure, meaning that there are a lot of holes in its structures. However, these holes are small and not well connected to each other. This means water gets stuck in these small holes due to friction and stickiness. This leads to a low permeability. This is Why Clay Has High Aquifer Porosity But Low Permeability.
Carbonate Minerals
03/06/25
“What are the special features of carbonate minerals?”
Minerals are made out of all types of materials. Minerals that contain carbonate ion, or (CO_2)^-2, make up a special class of Carbonate Minerals. Carbonate minerals have a softer texture and are soluble in hydrochloric acid.

Aquifer Porosity
03/05/25
“How can we quantify how much space an aquifer medium has?”
Aquifers exist because there is a void between rocks. The higher the void, the more water can flow through. This is quantified as the Aquifer Porosity, the ration of empty space within an aquifer medium to the entire volume.

Indicator Organisms
03/04/25
“How can an organism’s presence indicate environmental conditions?”
Organisms like bacteria and fungi may be present when certain conditions are present. Sometimes an organism’s presence is indicative of other environmental conditions. These Indicator Organisms are an important part of studying environmental factors. An example indicator organism is E. coli bacteria are present when there is fecal matter.
Decentralized Wastewater Treatment
03/03/25
“How can we create water treatment systems that purify water near their use?”
Centralized water treatment systems are the go-to for large, dense, and (relatively) wealthy urban areas. However, this typology may not work well for smaller, low-density communities in remote regions. Decentralized Wastewater Treatment, where wastewater is treated near the site of use, might be more applicable. Examples of decentralized water treatment systems include septic tanks and constructed wetlands.

Diffusion Contaminant Transport
03/02/25
“Why do contaminants diffuse from zones of great concentration to lower concentration?”
Contaminants enter substances in different concentrations. If the medium allows it, a contaminant will diffuse from a zone of high concentration to one of lower concentration. This Diffusion Contaminant Transport is important in understanding how contaminants move in substances like groundwater.
Contaminant Release Mechanisms
03/01/25
“How are contaminants released?”
Contaminants hurt whatever they come in contact with. Contaminants are released through a Contaminant Release Mechanism, such as leakages, spills, and burning.
Contaminant Transport
02/28/25
“How are contaminants transported?”
Contaminants can cause massive damage to living organisms. But how do contaminants move from one place to another? Well, through the process of Contaminant Transport contaminants can move through media such as air, water, and soil.
Plant Communities
02/27/25
“How can we describe groups of closely interdependent plants?”
Living beings live in communities. Plants are no exception. Plants that interact interdependently with each other in close geographic proximity form Plant Communities. Plant communities have definite visual boundaries, and form a foundation of ecosystems.
