Stormwater Management and Pollutant Removal

In an era characterized by rapid urbanization and climate change, the effective management of stormwater and the removal of pollutants have become critical priorities for urban planners and environmentalists alike. As cities continue to expand, impenetrable surfaces replace natural landscapes, leading to increased stormwater runoff and the accumulation of pollutants in water bodies.

Below we will explore the importance of pollutant removal and stormwater management strategies in urban environments, their impact on the environment and public health, and innovative solutions to address these challenges.

 

Understanding Stormwater Management

Definition and Importance of Stormwater Management

Stormwater management refers to the process of controlling and using stormwater runoff, which is the water generated from precipitation events, such as rain or snowmelt. This runoff flows over the land surface, streets, lawns, and other sites, carrying with it various pollutants it picks up along the way. Effective stormwater management systems are designed to capture, store, and treat this runoff to reduce flooding, prevent erosion, and improve water quality.

The importance of stormwater management cannot be overstated. Uncontrolled stormwater can lead to significant environmental, economic, and social problems. Proper stormwater management helps mitigate the adverse impacts of runoff by reducing flood risks, protecting water resources, and maintaining healthy ecosystems. It also contributes to the resilience of urban areas against extreme weather events and climate change.

 

Impacts of Urbanization on Stormwater Runoff

Urbanization dramatically alters the natural landscape, replacing permeable surfaces like soil and vegetation with impervious surfaces such as asphalt and concrete.These surfaces prevent water from naturally infiltrating the ground, leading to higher volumes and faster flow rates of runoff. This can cause several problems, including:

• Increased Runoff Volume and Velocity: Impervious surfaces prevent water from naturally infiltrating into the ground, leading to greater volumes of surface runoff. This runoff moves more quickly over paved surfaces, increasing the risk of flooding and erosion in urban areas.
• Reduced Groundwater Recharge: In natural landscapes, much of the precipitation infiltrates into the ground, replenishing groundwater supplies. Urbanization disrupts this process, reducing groundwater recharge and lowering water tables, which can affect water availability for human use and natural ecosystems.
• Altered Hydrological Cycles: The disruption of natural infiltration processes changes the hydrological cycle, leading to increased surface water flows and decreased base flows in rivers and streams. This can result in more frequent and severe floods and reduced water availability during dry periods.
• Degraded Water Quality: Urban runoff often contains a variety of pollutants from roads, rooftops, and industrial sites. These include oils, heavy metals, nutrients, sediments, and pathogens, which can significantly degrade water quality in rivers, lakes, and coastal waters.

 

Challenges Posed by Stormwater Pollution

Stormwater pollution presents numerous challenges for urban areas, affecting both the environment and public health. Some of the primary challenges include:

• Pollutant Load Management: Stormwater can carry a wide range of pollutants, including nutrients (such as nitrogen and phosphorus from fertilizers), heavy metals (from vehicle emissions and industrial activities), pathogens (from pet waste and sewage overflows), and organic pollutants (such as pesticides and oils). Managing these diverse pollutants requires comprehensive strategies and technologies to treat runoff effectively.
• Infrastructure Costs: Building and maintaining stormwater management infrastructure, such as detention basins, green roofs, permeable pavements, and rain gardens, can be costly. Municipalities often face financial constraints that limit their ability to invest in necessary stormwater systems.
• Regulatory Compliance: Stormwater management is often regulated at the federal, state, and local levels. Compliance with these regulations can be complex and resource-intensive. Municipalities must navigate a maze of permits, standards, and reporting requirements to meet legal obligations.
• Public Awareness and Engagement: Effective stormwater management also depends on public awareness and engagement. Educating residents and businesses about the importance of reducing pollution at the source and adopting best practices (such as proper disposal of waste and minimizing the use of fertilizers) is crucial for the success of stormwater programs.

 

Implications of Stormwater Pollution on Water Quality, Aquatic Ecosystems, and Human Well-Being.

The implications of stormwater pollution are extensive and multifaceted, impacting water quality, aquatic ecosystems, and human well-being:

• Water Quality – Stormwater pollution is a major contributor to water quality degradation. Pollutants in stormwater can lead to elevated levels of nutrients, sediments, and toxic substances in water bodies. This not only makes water unsafe for drinking and recreational activities but also complicates water treatment processes, increasing costs for municipalities and water utilities.
• Aquatic Ecosystems – Healthy aquatic ecosystems are vital for biodiversity, providing habitat for fish, amphibians, invertebrates, and plants. Stormwater pollution can disrupt these ecosystems in several ways:
  • Eutrophication: Excessive nutrients in runoff can cause algal blooms, which deplete oxygen levels in the water, leading to “dead zones” where aquatic life cannot survive.
  • Habitat Destruction: Sedimentation from stormwater can smother habitats, such as spawning grounds for fish and breeding sites for amphibians, reducing biodiversity.
  • Toxic Contamination: Heavy metals and organic pollutants can accumulate in the tissues of aquatic organisms, causing health issues and affecting food webs.
• Human Well-Being – The impact of stormwater pollution on human well-being is significant:
  • Public Health: Contaminated stormwater can introduce pathogens and toxic substances into drinking water supplies, posing serious health risks. Recreational waters polluted by stormwater runoff can also cause illnesses in swimmers and other users.
  • Flooding and Property Damage: Increased stormwater runoff can overwhelm drainage systems, leading to urban flooding. This can cause property damage, disrupt transportation, and necessitate costly emergency responses and repairs.
  • Economic Costs: The economic burden of stormwater pollution includes increased healthcare costs, higher water treatment expenses, and losses related to property damage and reduced recreational opportunities.

 

Pollutant Removal Techniques

Overview of Common Pollutants

As previously mentioned, urban runoff is a significant environmental concern, especially in densely populated areas. As water flows over the urban landscape during and after precipitation events, it picks up various pollutants that can degrade water quality and harm ecosystems. Understanding the common pollutants in urban runoff is crucial for developing effective management and mitigation strategies. Here, we explore some of the most prevalent contaminants found in urban runoff, including sediment, heavy metals, nutrients, bacteria, and hydrocarbons.

• Sediment – Sediment consists of particles of soil, sand, and minerals that are washed into water bodies by stormwater. In urban areas, sediment primarily originates from construction sites, unpaved roads, and eroding landscapes. Excessive sediment in water bodies can cloud the water, reducing light penetration and affecting aquatic plants’ ability to photosynthesize. Sediment can also smother fish eggs and benthic organisms, disrupt habitats, and clog fish gills, leading to reduced populations of sensitive species. From an infrastructure standpoint, accumulated sediment can clog stormwater systems, reducing their efficiency and increasing maintenance costs.
• Heavy Metals – Heavy metals in urban runoff include lead, copper, zinc, cadmium, and mercury. These pollutants often come from vehicle emissions, industrial discharges, building materials, and atmospheric deposition. Heavy metals are toxic to aquatic life, even at low concentrations. They can cause behavioral changes, reproductive issues, and mortality in fish and invertebrates. Heavy metals can also accumulate in the tissues of aquatic organisms, entering the food chain and posing risks to predators, including humans. Heavy metals are also known to negatively impact water quality, and can render water unsafe for drinking, fishing, and recreational activities.
• Nutrients – Nutrients such as nitrogen and phosphorus are essential for plant growth but can become pollutants when present in excessive amounts. Major sources in urban areas include fertilizers, pet waste, septic systems, and atmospheric deposition. High nutrient levels can lead to the overgrowth of algae in water bodies, causing eutrophication. This process depletes oxygen levels in the water, resulting in dead zones where aquatic life cannot survive. Algal blooms caused by nutrient pollution can also produce toxins that are harmful to both aquatic life and humans, impacting drinking water sources and recreational waters. Furthermore, the loss of oxygen and changes in water chemistry can reduce biodiversity, favoring algal species over more sensitive aquatic plants and animals.
• Bacteria – Bacteria in urban runoff, particularly fecal coliforms like E. coli, primarily come from pet waste, sewage overflows, failing septic systems, and wildlife. Bacteria in water can make it unsafe for drinking, and can even cause gastrointestinal illnesses and infections in humans who come into contact with contaminated water through swimming or other recreational activities. In addition to making humans sick, high levels of bacteria can disrupt the natural balance of aquatic ecosystems, affecting the health and diversity of aquatic organisms.
• Hydrocarbons – Hydrocarbons are another common pollutant in urban runoff, originating mainly from vehicle emissions, motor oil, and industrial activities. These organic compounds, which include substances like benzene, toluene, and xylene, can be toxic to aquatic life even at low concentrations. Hydrocarbons tend to form oily films on the surface of water bodies, reducing oxygen transfer and impacting aquatic organisms’ respiration. Chronic exposure to hydrocarbons can lead to bioaccumulation in the tissues of fish and other aquatic organisms, posing long-term health risks and disrupting food chains. Hydrocarbons also contribute to the degradation of water quality, making it less suitable for drinking, recreational activities, and supporting diverse ecosystems.

Best Management Practices

Best Management Practices (BMPs) refer to methods, measures, or practices used to prevent or reduce the pollution of water bodies from stormwater runoff. They encompass a wide range of structural and non-structural solutions designed to manage the quantity and quality of runoff in both urban and rural settings. BMPs aim to reduce the velocity, volume, and pollutant load of stormwater before it reaches waterways. BMPs are generally categorized into two main types: structural and non-structural.

Non-Structural BMPs

Non-structural BMPs include policies, procedures, and practices aimed at preventing pollution at the source, including:
Public Education and Outreach – Informing the public about the impact of stormwater pollution and ways to reduce it, such as proper disposal of waste and minimizing the use of fertilizers.

• Good Housekeeping Practices – Ensuring that activities such as vehicle maintenance and landscaping are conducted in ways that minimize pollutant runoff.
• Erosion and Sediment Control – Implementing measures to prevent soil erosion and manage sediment at construction sites.
• Urban Planning and Zoning – Designing communities to include green spaces and reduce impervious surfaces.
• Regulatory Measures – Enforcing laws and regulations that control stormwater pollution, such as requiring permits for discharges and setting limits on pollutant levels.

 

Structural BMPs

Structural BMPs involve the construction and implementation of facilities or devices designed to manage stormwater. MKB Company offers both above-ground and below-grate BMPs, often found in the below applications:

Channel Protection: Channel Protection involves measures to stabilize and protect channels from erosion caused by increased stormwater runoff. Channel protection can be used to establish, sustain, and reinforce vegetation in areas of concentrated flow and intense hydraulic pressure that typically undermine vegetation growth.

Bioswales: Bioswales are specially designed landscape features engineered to reduce silt, pollution, and other particles from stormwater runoff. These permanent, vegetated, shallow depressions or channels are designed to direct, slow, filter, and partially absorb stormwater. By facilitating infiltration of the initial surge of runoff and filtering subsequent flows, bioswales significantly improve water quality.

Check Dams: Check Dams are a simple and cost-effective BMP typically utilized in ditches, channels, and swales to safeguard specific areas by slowing the velocity of concentrated stormwater flows, thereby reducing bed erosion and filtering out sediment, pollutants, and other particles.

Inlet Protection: Inlet Protection involves installing barriers or filters around storm drain inlets to prevent sediment and debris from entering the stormwater system.

Perimeter Controls: Perimeter Controls serve as barriers to retain sediment on construction sites. Typically referred to as “perimeter controls,” these sediment control products are installed at the down-gradient boundaries of construction sites. They are placed down-slope of any disturbed areas to provide effective erosion control and filtration for runoff, ensuring sediment is contained within the site.

Slope Interruptions: Slope Interruptions minimize soil erosion by shortening slope lengths, thereby dissipating the energy of overland sheet flow runoff. By reducing runoff velocity, these practices decrease the likelihood of rill erosion on hill slopes. When pollution removal is required, EnviroSoxx can be incorporated within this BMP.

Green Infrastructure Solutions

Traditional stormwater management systems often rely on gray infrastructure, such as pipes and sewers, which can be costly and environmentally disruptive. Green infrastructure presents an innovative and sustainable alternative, integrating natural processes with engineered solutions to manage stormwater more effectively.

Green infrastructure refers to a network of natural and semi-natural systems that provide ecological benefits and enhance urban resilience. Unlike gray infrastructure, which primarily focuses on moving water away from urban areas, green infrastructure aims to manage stormwater at its source through absorption, infiltration, and evapotranspiration. This approach not only mitigates flooding but also improves water quality and enhances urban environments.

 

Key Benefits of Green Infrastructure

Improved Water Quality: Green infrastructure helps filter pollutants from stormwater before it enters water bodies. Vegetation and soil in green infrastructure systems act as natural filters, removing sediments, nutrients, heavy metals, and other contaminants. This leads to cleaner rivers, lakes, and aquifers, benefiting both ecosystems and human health.

Reduced Flooding: By absorbing and slowing down stormwater runoff, green infrastructure reduces the volume and peak flow of water entering drainage systems. This decreases the risk of urban flooding and alleviates the burden on traditional stormwater infrastructure.

Enhanced Urban Aesthetics and Biodiversity: Green infrastructure integrates natural elements into urban landscapes, enhancing the aesthetic appeal and providing habitats for wildlife. Parks, green roofs, and vegetated swales contribute to urban biodiversity and create pleasant spaces for recreation and community activities.

Climate Resilience: Green infrastructure enhances urban resilience to climate change by managing extreme weather events and mitigating urban heat islands. Vegetation cools the air through shade and evapotranspiration, reducing energy demands for cooling and improving overall urban comfort.

 

Green Infrastructure Applications and Products

Green Infrastructure Applications

In addition to the bioswales and channel protection BMPs described above, Green Infrastructure solutions can include:

Filtration Systems: Filtration Systems are designed to mimic natural processes by utilizing vegetation, soil, and other organic materials to capture, treat, and infiltrate stormwater runoff. Filtration systems provide a sustainable approach to managing stormwater by reducing the volume of runoff and removing pollutants before they reach natural water bodies.

Gabions: Gabions are wire mesh containers filled with rock, concrete, sand, or soil that can be strategically placed to slow down and retain stormwater runoff. When placed in the path of runoff, they create barriers that allow water to gradually infiltrate into the ground rather than flowing rapidly over impervious surfaces. This helps reduce erosion, sedimentation, and flooding downstream.

Walls, Slopes, and Shores: Living walls, slopes, and shores are innovative structures covered in vegetation that offer numerous environmental benefits, including permanent stabilization for extreme grade changes, along with stormwater management. Living walls are designed with a built-in irrigation system that supplies water to the plants. When it rains, the plants absorb water through their roots, reducing the amount of stormwater runoff that reaches the ground below. This process helps capture and retain stormwater, preventing it from overwhelming drainage systems and reducing the risk of flooding. Additionally, the soil and vegetation on living walls act as natural filters, trapping pollutants and sediments from stormwater runoff. These aesthetically pleasing solutions also provide habitat and food sources for birds, insects, and other wildlife, thus contributing to urban biodiversity.
