California Water Pollution: A Troubling Reality Check

California's water is contaminated with pollutants, including pesticides, metals, pathogens, trash, sediment, and toxic chemicals. The state's rivers, lakes, bays, and wetlands are plagued by these contaminants, making the water unsafe for swimming, fishing, or drinking. Underserved communities, particularly communities of color, bear the brunt of the consequences of unsafe water, facing health issues such as respiratory diseases, gastrointestinal illnesses, and even cancer. The agricultural sector, with its widespread use of pesticides and fertilizers, is a significant contributor to water pollution in California. The state is facing challenges in ensuring safe and adequate water supplies for its residents, and efforts are being made to address the issue, including investing in pollution control and implementing new thresholds for chemical contamination.

California's water rights system and systemic racism

California's water rights system has been criticised for its role in perpetuating systemic racism and inequality. The state's water rights system was established during a period of tribal land seizure, genocide, and discriminatory laws that prevented people of colour from owning land or water rights. As a result, the current system has been described as being founded on "racism and violence", with tribes and communities of colour disproportionately affected by water pollution and a lack of access to clean water.

The senior water rights holders in California, who gained their status by profiting from the state's violent and racist history, pay significantly less for water than almost all other residents. These senior rights holders, who are overwhelmingly white, are not required to obtain permits or pay fees, while those with more junior rights are burdened with additional costs. This has led to accusations that the water rights system is deeply flawed in addressing equity and that it prioritises agriculture over human health and safety.

The high cost of water in California, influenced by its racist and exclusionary past, further exacerbates the issue. The price of water is often determined by its transportation costs, resulting in a substantial cost differential between different communities. This has led to a situation where some residents, particularly those in disadvantaged areas, are forced to rely on bottled water for drinking due to contaminated or dry wells. Latino farm communities, for example, struggle with poverty and pollution, with elevated levels of contaminants such as arsenic, nitrate, and 1,2,3-trichloropropane (1,2,3-TCP) in their water systems.

Efforts are being made to address these issues, with the State Water Resources Control Board's Safe and Affordable Funding for Equity and Resilience (SAFER) program working to ensure access to safe and affordable drinking water for all Californians. Additionally, the Newsom administration has been pressured to hold polluters accountable and include tribal and environmental justice representatives in water quality regulatory decision-making. However, there are also calls for more comprehensive reforms to the water rights system, including overhauling the rights process and addressing the link between water rights and wealth, power, and privilege.

In conclusion, California's water rights system has been criticised for perpetuating systemic racism and inequality, with tribes and communities of colour disproportionately affected by water pollution and a lack of access to clean, affordable water. While efforts are being made to address these issues, more comprehensive reforms to the water rights system may be necessary to ensure equitable access to this essential resource.

Contaminants in California's water

California's water quality is affected by a variety of contaminants, which pose significant risks to public health and the environment. The state's water pollution challenges are diverse and vary across different regions.

One of the most pressing issues is the presence of harmful chemicals and heavy metals in the water. These contaminants, which include arsenic, nitrate, and 1,2,3-trichloropropane (1,2,3-TCP), are often linked to serious health problems such as cancer and developmental issues in babies. In the San Joaquin Valley, for instance, the widespread use of soil fumigants in the 1950s contaminated groundwater with 1,2,3-TCP, and elevated levels of this chemical continue to affect water sources in the region.

Pollution from industrial and municipal wastewater is also a major concern. These discharges introduce toxins such as mercury and phosphorus into waterways, threatening aquatic life and accumulating in fish consumed by humans. Additionally, runoff from farms and cities contributes to toxicity and the spread of respiratory diseases and gastrointestinal illnesses. For example, Stockton is facing a growing number of harmful algal blooms due to water pollution.

Salt buildup is another prevalent issue for both cities and farms in California. Salt occurs naturally in some soils but is also found in fertilizers, animal waste, and urban wastewater. While it is not considered a toxic contaminant, salt buildup can have detrimental effects on water quality and the environment.

Furthermore, waterborne pathogens, including disease-causing bacteria and viruses from human and animal waste, pose significant risks to human health. Legionnaires' disease, cholera, giardia, and typhoid are some of the illnesses that can be contracted from contaminated drinking water.

The sources of water pollution in California are both human-induced and naturally occurring. Past activities, such as mercury from mining, continue to impact water quality, while ongoing sources of pollution, like farm runoff and industrial waste, persist. The state has made some progress, with nearly a million more Californians gaining access to safe drinking water in recent years. However, addressing water pollution and ensuring safe and reliable water supplies for all remains a critical challenge for California.

Water pollution control investments

Despite the passage of the federal Clean Water Act nearly 50 years ago, which aimed to restore America's waters, California continues to face significant water pollution issues. 95% of the state's rivers, lakes, bays, and wetlands are plagued by pesticides, metals, pathogens, trash, and sediment, making them unsafe for swimming, fishing, or drinking. This situation disproportionately impacts underserved communities of colour, who are often treated as "sacrifice zones" in terms of water quality.

To address these pressing issues, substantial investments in water pollution control are necessary. Currently, California spends approximately $10 billion annually on water pollution control efforts, with a significant portion allocated to addressing "point sources" of pollution, such as wastewater treatment. However, rising costs and constraints on fundraising have resulted in a funding gap for stormwater programs, requiring new investments.

One significant source of funding for water infrastructure upgrades in California is the Clean Water State Revolving Fund (CWSRF) and the Drinking Water State Revolving Fund (DWSRF), which are federal-state water investment partnerships. In 2024, the Biden-Harris Administration announced $276 million in funding for California through these funds, as part of a five-year, $50 billion investment in water infrastructure across the nation. This funding is intended to support local jobs, economic resilience, and long-term sustainability, especially in disadvantaged communities that have historically lacked equitable funding.

To ensure that these investments reach the communities that need them the most, the Bipartisan Infrastructure Law mandates that most of the funding be directed towards disadvantaged communities. Additionally, the EPA's Water Technical Assistance program aims to empower historically excluded communities by providing them with the capacity-building and assistance needed to identify water challenges, plan infrastructure upgrades, and apply for funding.

While these investments are a step in the right direction, California must also address systemic issues within its water rights system, which has been criticised as a core cause of racism and inequality. The state must hold polluters accountable and ensure that communities suffering from poor health due to environmental hazards have a stronger voice in water quality regulatory decision-making. By addressing both the financial and systemic aspects of the problem, California can make significant strides towards ensuring safe and accessible water for all its residents.

Water quality regulations

Despite efforts to improve water quality in California, the state continues to face significant challenges in ensuring safe and reliable drinking water for its residents. Various factors, such as agricultural practices, industrial pollution, and outdated water rights systems, have contributed to the contamination of water sources, leading to health issues and environmental concerns.

The State Water Resources Control Board (State Water Board) in California was established by the state legislature in 1967. The board has joint authority over water allocation and quality protection, enabling it to provide comprehensive protection for the state's water resources. Nine Regional Water Quality Control Boards support the State Water Board in developing and enforcing water quality objectives and implementation plans. These regional boards take into account local factors such as climate, topography, geology, and hydrology to ensure that the standards are tailored to the specific needs of each region.

The water quality standards in California are outlined in Basin Plans administered by the Regional Water Quality Control Boards and statewide Plans and Policies overseen by the State Water Resources Control Board. These plans include specific provisions to address various contaminants and protect vulnerable communities. For example, the Water Quality Control Plan for Inland Surface Waters, Enclosed Bays, and Estuaries of California considers tribal cultural use and subsistence fish consumption, sets mercury water quality objectives, and provides flexibility in permit compliance.

Additionally, the federal Clean Water Act, passed by Congress 49 years before 2021, aimed to restore water quality across the nation. Despite this, California's water bodies continue to be plagued by pesticides, metals, pathogens, trash, and sediment, rendering them unsafe for swimming, fishing, or drinking. Underserved communities of colour often bear the brunt of these issues, facing higher pollution levels and inadequate access to clean water.

To address these challenges, California has taken steps to improve water quality. For instance, the state has established detection limits for reporting (DLRs) and set standards for specific chemicals, such as arsenic, 1,2,3-Trichloropropane (1,2,3-TCP), and nitrate. Efforts have also been made to include tribal and environmental justice representatives in decision-making processes, ensuring that the voices of impacted communities are heard and their needs are addressed.

In conclusion, while California has implemented various regulations and initiatives to improve water quality, significant work remains to be done to ensure that all residents have access to safe and reliable drinking water. Addressing the underlying causes of water pollution, holding polluters accountable, and prioritising the needs of underserved communities are crucial steps towards achieving this goal.
