Why Groundwater Rise Will Flood Pipes
06/16/26
“Why will groundwater rise flood pipes?”
Climate change is causing groundwater to rise in many places. The elevated water table will hit underground infrastructure such as pipes. Groundwater will flood into the pipes through cracks and joints. The extra water in the pipes will reduce their capacity to convey stormwater and wastewater, leading to more infrastructure and public health damage. This is Why Groundwater Rise Will Flood Pipes.
How Pumps Can Lower Water Tables

“How can pumps lower water tables?”
People may need to lower water tables for construction, flood safety, or contamination remediation. One way to accomplish this is to use a pump to suck out the water from the aquifer like a straw. The water table will naturally get smaller when water is removed. This is How Pumps Can Lower Water Tables.

Why Heat Release From Air Conditioners Can Make Neighborhoods Hotter
06/11/26
“Why can heat release from air conditioners make neighborhoods hotter?”
Air conditioner works by ejecting heat from one space to another. This typically manifests in urban areas as cooling living and office spaces at the expense of the outside air. If enough air conditioning systems are active, then they can noticeably raise the temperature of the surrounding neighborhood. Research from Arizona State University demonstrated that this effect is especially noticeable at nighttime.
Why Historically Redlined Neighborhoods Are Especially Vulnerable to Pollution From Groundwater Flooding
06/07/26
“Why are historically redlined neighborhoods especially vulnerable to pollution from groundwater flooding?”
Redlining in the US forcibly segregated Black and Brown communities in urban areas into neighborhoods with the lowest amount of public investment. Racist municipal officials often would zone toxic industries in these neighborhoods. These industries would accumulate contaminants underground over their course of operation. Groundwater flooding releases these contaminants from the earth to the surface, harming the communities that live nearby. This is Why Historically Redlined Neighborhoods Are Especially Vulnerable to Pollution From Groundwater Flooding. Examples include West Oakland in California and Southeast Queens in New York.

How Heavy Rains Can Increase Groundwater Contamination Risk
06/06/26
“How can heavy rains increase groundwater contamination risk?”
The longer an area rains and the more rain it receives, the higher the volume of rainwater will seep into the groundwater. If pollutants are present on the surface, then infiltrated rainwater will carry them down into the groundwater and pollute it. This is How Heavy Rains Can Increase Groundwater Contamination Risk.
Why a Lot of Basements in Southeastern Queens Flood After Heavy Rain
06/05/26
“Why do so many basements in Southeastern Queens flood after heavy rain?”
If you’re resident of Southeastern Queens in NYC with a basement, there’s a good chance you’ve experienced your basement flood after a heavy rain. Why does this happen, and what can we do to protect against it? Well, Southeastern Queens has a very high water table. When a downpour happens, the extra rain goes down into the soil and into the ground, raising the watertable. If the watertable gets high enough, it can seep up onto the ground and into your basement. This is Why a Lot of Basements in Southeastern Queens Flood After Heavy Rain. You can protect your home against basement flooding by elevating your home, remodeling your interior, or even simply fixing internal drainage.

How Groundwater Flooding Can Lead to More Surface Pollution
06/04/26
“How can groundwater flooding lead to more surface pollution?”
Pollutants are often stored in aquifers. When groundwater floods out of aquifers into the streets, it brings those pollutants with it. This is How Groundwater Flooding Can Lead to More Surface Pollution.
Why Sea-Level Rise Will Lead to More Groundwater Flooding
06/03/26
“Why will sea-level rise lead to more groundwater flooding?”
The water table level in coastal areas is proportional to the pressure from coastal waters. The pressure from coastal waters is proportional to the surrounding sea-level height. When the sea-level rises from climate change, so will the water table, which can lead to groundwater flooding. This is Why Sea-Level Rise Will Lead to More Groundwater Flooding.
Passive Earth Pressure

“What’s the pressure of soil when a structure pushes into the soil?”
Structures receive pressure from the Earth when a structure pushes into the soil. This comes from a reaction to compression. This Passive Earth Pressure is a fundamental part of civil engineering.
