Comprehensive Guide to Water Quality in Mississippi State: Contaminants, Issues, and Water Filtration Solutions

by Ryan Moreau / updated October 1st, 2023

Mississippi is a state rich in water resources, from the mighty Mississippi River to its numerous lakes, aquifers, and coastal waterways. Despite this abundance, residents face significant water quality challenges stemming from agricultural runoff, industrial pollution, and aging infrastructure. In this comprehensive guide, we delve into the common contaminants affecting Mississippi’s water, regional water quality issues, and the most effective filtration solutions. Begin by using our Water Quality Tool to receive a personalized analysis of your local water conditions.

Overview of Mississippi’s Water Sources

Mississippi’s water supply is diverse, encompassing surface water from rivers and lakes, as well as groundwater from various aquifers. Key water sources include:

Mississippi River: One of the largest rivers in North America, it influences the state’s water quality and provides for both municipal and industrial uses.
Groundwater Aquifers: The state’s aquifers, such as the Mississippi River Valley Alluvial Aquifer and the Sparta Aquifer, are crucial sources of drinking water for many communities.
Reservoirs and Lakes: Bodies like Ross Barnett Reservoir and Grenada Lake serve as important water supplies and recreational areas.
Coastal Waterways: Along the Gulf Coast, estuaries and bays contribute to the local water supply and ecosystem health.

Ensuring the quality of these varied water sources requires continuous monitoring and advanced treatment solutions to address both natural and human-made contaminants.

Common Water Quality Contaminants in Mississippi

Mississippi’s water sources are susceptible to a range of contaminants due to agricultural activities, industrial operations, and natural geological factors. To understand what may affect your area, start with our Water Quality Tool and review these common issues:

1. Lead and Copper

Aging infrastructure in many Mississippi communities can lead to elevated levels of lead and copper in drinking water. Corrosion of old pipes and plumbing fixtures is a primary source of these metals, which pose significant health risks, especially to children and pregnant women.

Water Filtration Options for Lead and Copper: Reverse Osmosis Water Filters, Activated Carbon Water Filters

2. Iron and Manganese

High levels of iron and manganese are common in Mississippi’s groundwater sources. While not typically harmful to health, these minerals can affect the taste, odor, and color of water, and can cause staining on fixtures and laundry.

Water Filtration Options for Iron and Manganese: Whole House Water Filters with specialized media for iron and manganese removal

3. Agricultural Chemicals (Pesticides and Herbicides)

Runoff from agricultural lands can introduce pesticides and herbicides into both surface water and groundwater sources. Chemicals such as atrazine and glyphosate have been detected in various regions, posing potential health risks.

Water Filtration Options for Agricultural Chemicals: Activated Carbon Water Filters, Reverse Osmosis Water Filters

4. Nitrates

High nitrate levels are often a result of fertilizer application in agricultural areas and can contaminate both surface water and groundwater. Nitrates are particularly dangerous for infants, causing conditions like methemoglobinemia or “blue baby syndrome.”

Water Filtration Options for Nitrates: Reverse Osmosis Water Filters

5. Bacterial Contamination

Microbial contaminants, including E. coli and coliform bacteria, can enter water supplies due to inadequate treatment, septic system failures, or after flooding events common in Mississippi. These pathogens can cause serious gastrointestinal illnesses.

Water Filtration Options for Bacterial Contamination: Reverse Osmosis Water Filters with UV disinfection, UV Water Purifiers

6. Industrial Contaminants (PFAS and VOCs)

Industrial activities, particularly in areas with manufacturing plants and petroleum processing, have led to contamination with per- and polyfluoroalkyl substances (PFAS) and volatile organic compounds (VOCs). These chemicals are persistent in the environment and can have long-term health effects.

Water Filtration Options for PFAS and VOCs: Activated Carbon Water Filters, Reverse Osmosis Water Filters

7. Arsenic

Certain regions in Mississippi have naturally occurring arsenic in groundwater due to the erosion of arsenic-rich rocks and minerals. Long-term exposure to arsenic can lead to skin damage, circulatory system issues, and an increased risk of cancer.

Water Filtration Options for Arsenic: Reverse Osmosis Water Filters, adsorption media like iron oxide filters

8. Radionuclides

Some areas may experience contamination with naturally occurring radioactive materials, such as uranium and radium, which can leach into groundwater from certain geological formations.

Water Filtration Options for Radionuclides: Reverse Osmosis Water Filters, ion exchange systems

9. Chlorination Byproducts

While chlorine is essential for disinfecting public water supplies, it can react with organic matter to form disinfection byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs), which are linked to health risks over long-term exposure.

Water Filtration Options for Chlorination Byproducts: Activated Carbon Water Filters

Regional Water Quality Challenges in Mississippi

Mississippi’s unique geography and industrial landscape contribute to specific water quality issues across different regions. According to the Mississippi Department of Environmental Quality (MDEQ) and the Environmental Protection Agency (EPA), key challenges include:

1. Delta Region: Agricultural Runoff

The Mississippi Delta is a heavily agricultural area where extensive use of fertilizers and pesticides leads to runoff that contaminates local water sources with nitrates and chemicals.

Efforts are being made to implement best management practices (BMPs) in agriculture to reduce runoff (EPA – Nonpoint Source Agriculture).

2. Industrial Corridors

Areas along the Mississippi River and Gulf Coast host various industrial facilities, including chemical plants and refineries. These industries contribute to the contamination of water sources with heavy metals, PFAS, and VOCs.

3. Rural Areas: Private Well Vulnerabilities

Many rural residents rely on private wells that may not be regularly tested or adequately protected, leading to increased risk of contamination from bacteria, nitrates, and naturally occurring elements like arsenic.

4. Coastal Areas: Saltwater Intrusion

Along the Gulf Coast, overuse of groundwater and rising sea levels contribute to saltwater intrusion into freshwater aquifers, affecting the taste and potability of water supplies.

Desalination techniques and careful water management are necessary to address this issue.

General Water Characteristics in Mississippi

Understanding the overall characteristics of Mississippi’s water can help in choosing appropriate treatment solutions:

1. Water Hardness

Water hardness varies across the state but is generally considered moderate to hard due to the presence of minerals like calcium and magnesium from sedimentary rock formations.

Hard water can lead to scale buildup in plumbing and reduce the efficiency of soaps and detergents.

Installing a water softener can mitigate these issues. To determine if a water softener is right for you, use our Water Softener Calculator.

2. pH Levels

Mississippi’s water sources can vary in pH, with some areas experiencing slightly acidic or alkaline conditions, which can impact corrosion rates in pipes and the effectiveness of disinfectants.

Acidic Water: May cause leaching of metals from pipes.
Alkaline Water: Can lead to scaling and mineral deposits.

Acid neutralizers or chemical feed pumps can adjust pH levels to protect plumbing and improve water quality.

3. Sediment and Turbidity

High sediment levels can occur, especially after heavy rainfall or flooding, common in the state. Suspended particles can harbor bacteria and reduce the efficiency of disinfection processes.

Pre-filtration: Sediment filters can remove particles and protect downstream filtration systems.

4. Natural Organic Matter

Surface waters often contain organic materials from decaying vegetation. When chlorinated, these can form harmful disinfection byproducts.

Activated carbon filters can effectively reduce these compounds and the resulting byproducts.
