Oklahoma's Water Pollution: The Costly Crisis

Water pollution is a pressing issue in Oklahoma, with far-reaching economic and environmental implications. The state's water resources are under threat from various pollutants, including nutrient pollution, runoff, and erosion. The Illinois River, flowing between Arkansas and Oklahoma, is particularly affected by nutrient pollution caused by excess nitrogen and phosphorus from city and industrial discharges. Oklahoma's watersheds, which sustain life and support various economic activities, are also vulnerable to pollution. The cost of water pollution in Oklahoma is significant, impacting public health, the environment, and the state's economy. With water quality issues, the discussion revolves around the financial burden of water filtration systems and the disparities between rural and urban communities. This article will delve into the economic and environmental costs of water pollution in Oklahoma and explore potential solutions to mitigate these challenges.

The financial cost of water pollution in Oklahoma

While there is no specific figure for the financial cost of water pollution in Oklahoma, water pollution has significant economic implications for the state. Water pollution affects not only the quality of drinking water but also the health of watersheds, which are vital for agriculture, manufacturing, and tourism.

One example of water pollution in Oklahoma is the Illinois River, which flows from Arkansas into northeast Oklahoma. Nutrient pollution, caused by excess nitrogen and phosphorus in the air and water, has led to issues such as "algal blooms" and low dissolved oxygen concentrations in Tenkiller Ferry Lake, which the river feeds into. The U.S. Environmental Protection Agency (EPA) has partnered with Oklahoma, Arkansas, and the Cherokee Nation to address this issue by developing science-based water quality models.

The financial cost of water pollution can be significant for individuals and communities. In Oklahoma, the Department of Environmental Quality (DEQ) is responsible for ensuring safe drinking water. However, water quality issues may lead to residents having to purchase bottled water or invest in expensive filtration systems, which can range from $20 for a basic filter to over $1000 for a whole-house system. Not all consumers can afford these additional costs, and there may be disparities in water quality between rural and urban areas.

Water pollution also affects watersheds, which are vital for various economic sectors. According to the EPA, more than $450 billion in foods, fiber, manufactured goods, and tourism depend on healthy watersheds. Protecting watersheds is crucial for sustaining these economic activities and ensuring clean water for all.

Overall, while the exact financial cost of water pollution in Oklahoma is challenging to quantify, it likely runs into the billions of dollars when considering the impact on drinking water, watershed health, and the economy as a whole.

The impact of water pollution on drinking water quality

Water pollution is a pressing issue that jeopardizes human health and the environment. It occurs when harmful substances, often chemicals or microorganisms, contaminate water sources, degrading water quality and making it unsafe for human consumption. This contamination of drinking water has severe impacts on human health, leading to various diseases and health complications.

In Oklahoma, the Department of Environmental Quality (DEQ) is responsible for ensuring safe drinking water for its residents. While social media data and net sentiment analysis indicate slightly negative conversations surrounding tap water, with specific concerns arising around the water crisis in Flint, Michigan, it is challenging to determine the precise quality of drinking water in the state.

Water pollution affects drinking water quality by introducing various contaminants, including chemicals, microbes, and radionuclides. These contaminants can originate from human activities such as industrial and agricultural practices, with organic solvents, petroleum products, pesticides, fertilizers, and heavy metals finding their way into water sources. Additionally, human and animal waste from sewage, septic systems, and wildlife can carry harmful microbes like Giardia, Cryptosporidium, and E. coli into drinking water.

To address the impact of water pollution on drinking water quality, interventions such as chlorination, safe storage, and the provision of treated and clean water are essential. Additionally, epidemiological studies are crucial for developing health-friendly bathing water quality standards, and whole-process supervision of water quality is necessary to reduce the incidence of cancer caused by water pollution.

The Illinois River Watershed and Tenkiller Ferry Lake models

The Illinois River is a tributary of the Arkansas River, flowing between the states of Arkansas and Oklahoma. The river begins in the Ozark Mountains in Arkansas and flows into Oklahoma, where it eventually runs into Tenkiller Ferry Lake.

Phosphorus levels in the Illinois River are a cause for concern, as they are often elevated due to various city and industrial discharges, as well as nonpoint source runoff. This nutrient pollution, caused by excess nitrogen and phosphorus, can lead to significant environmental challenges and costs. The downstream impact of this pollution on Tenkiller Ferry Lake includes "algal blooms" and low dissolved oxygen concentrations.

To address these issues, the U.S. Environmental Protection Agency (EPA) partnered with Arkansas, Oklahoma, and the Cherokee Nation to develop science-based water quality models for the Illinois River Watershed Basin and Lake Tenkiller. These models, known as the Illinois River Watershed HSPF model and the Tenkiller Ferry Lake EFDC model, were completed and released to partnering agencies in 2018. The purpose of these models is to provide a scientifically sound representation of the entire Illinois River Watershed, allowing agencies to evaluate options for reducing phosphorus loadings from sources in northeast Oklahoma and northwest Arkansas.

The calibration and validation of these models involved both graphical comparisons and statistical tests, ensuring their accuracy and reliability. The partnering agencies continue to collaborate and share information, encouraging feedback and involvement from stakeholders within their jurisdictions.

The role of the Oklahoma Department of Environmental Quality (DEQ)

The Oklahoma Department of Environmental Quality (DEQ) is a government department under the Governor of Oklahoma. It was created in 1993 during the term of Governor David Walters and is responsible for protecting human health and safeguarding the state's natural environment, including its air, water, and land. The DEQ plays a crucial role in maintaining and improving water quality in Oklahoma.

One of the key roles of the DEQ is to ensure the safety of Oklahoma's water. This includes periodically testing water sources, such as wells, to monitor water quality and identify any potential contaminants. The DEQ provides informative resources and guidance to help residents understand the importance of testing their water and offers assistance through its State Environmental Lab. This lab also provides analytical support to various programs within the DEQ and other state agencies, as well as to the state's public water supply systems.

The DEQ is also responsible for maintaining water quality standards in Oklahoma's lakes, rivers, and streams. This involves implementing and enforcing environmental policies and regulations to reduce water pollution and improve water quality. The DEQ works in cooperation with other state agencies to address water quality issues and ensure that Oklahoma's water resources are protected.

Additionally, the DEQ's Land Protection Division plays a vital role in managing hazardous waste and solid waste treatment, storage, and disposal facilities. This includes permitting and inspecting certain underground injection wells and managing radioactive materials. The division also focuses on restoring contaminated land to safe and usable conditions through various cleanup programs. By effectively managing hazardous waste and remediating contaminated sites, the DEQ helps prevent water pollution and protects both human health and the environment.
