Malibu's Water Quality: Is It Safe To Swim?

Malibu's beaches are a popular attraction, but is the water clean and safe? Malibu has received both positive and negative ratings for its beaches and freshwater areas. While two Malibu beaches, Nicholas Beach and Las Tunas, were listed among the top 51 beaches in Los Angeles County for water quality, Malibu Creek and Las Virgenes Creek were rated poorly, with the latter being among the 10 worst freshwater recreation areas in the county. Malibu is home to a portion of Areas of Special Biological Significance (ASBS), which are protected coastal areas created to preserve local marine ecosystems and prohibit pollutants from entering the ocean. Despite these protections, concerns have been raised about the impact of wildfires and pollution on the water quality in Malibu, with elevated levels of heavy metals and harmful algal blooms detected in some areas.

Malibu's water pollution sources

One of the main sources of water pollution in Malibu is urban runoff. This occurs when rainwater flows over impervious surfaces, such as roads and parking lots, picking up pollutants like oil, grease, and debris, and carrying them into nearby waterways. Malibu has implemented measures to capture and treat stormwater, such as the use of recycled water and local stormwater management plans.

Agricultural activities also contribute to water pollution in Malibu. Fertilizers, pesticides, and animal waste from farms and gardens can wash into creeks and rivers during irrigation or rain events, leading to contaminated water sources. The use of graywater, gently used water from bathroom sinks, showers, and washing machines, is encouraged in Malibu to reduce the impact of wastewater on the environment.

In addition, Malibu has experienced challenges with polluted beaches. While some beaches, such as Nicholas Beach, have been recognized for their clean water quality, others like Las Virgenes Creek have been listed among the worst freshwater recreation areas in Los Angeles County due to high levels of harmful bacteria. The Santa Monica Pier, located near Malibu, has also struggled with water pollution, ranking as one of the most polluted beaches in California.

Natural factors, such as hillsides and eroding slopes, can also contribute to water pollution in Malibu. When water quickly flows over compacted soil or washes away dirt from slopes, it can pick up pollutants and sediment, leading to contaminated waterways. To address this, Malibu has projects like Legacy Park, which helps keep pollution out of Malibu Creek, Malibu Lagoon, and Surfrider Beach. Overall, Malibu continues to work towards conserving and protecting its water resources through various initiatives and programs.

Malibu's water quality in reports

Malibu's water quality has been a concern for residents and environmentalists, with a focus on both freshwater and seawater sources. Malibu Creek, for instance, has been the subject of conservation efforts to keep pollution out of the Malibu Creek, Malibu Lagoon, and Surfrider Beach. The city has implemented various measures to protect its water resources, including the development of Legacy Park, which helps keep pollution out of these water bodies.

The 32nd Heal the Bay Annual Beach Report Card for 2021 graded over 700 beaches and logged clean water-quality marks between April and October. Two Malibu beaches, Las Tunas, and Nicholas Beach, were among the top 51 beaches in the Los Angeles County Beach Honor Roll List. However, Malibu Creek rated poorly on the River Report Card, with Las Virgenes Creek being among the 10 worst freshwater recreation areas in the county.

In terms of seawater, Malibu faces challenges with pollution from various sources. Heal the Bay, a non-profit organisation, has been actively involved in investigating and addressing water quality issues in Malibu. Their investigations following heavy seasonal rains revealed that toxic pollutants, including harmful heavy metals, washed into the intertidal zones from burned structures and scorched earth in Malibu and nearby areas. These metals pose risks to marine life and, consequently, to humans through the consumption of seafood.

The Santa Monica Pier, located near Malibu, has been listed among the most polluted beaches in California due to high levels of harmful bacteria. While projects have been implemented to improve water quality in the area, it remains a concern. Malibu is also home to a portion of Areas of Special Biological Significance (ASBS), which are protected coastal areas supporting a rich variety of aquatic life. The city works diligently to protect these areas from pollution, implementing "Special Protections" to prevent pollutants from entering the ocean through storm drains and natural streams.

Malibu's beach water safety

The Good

Malibu has been recognised for its efforts to maintain clean beaches, with two of its beaches, Las Tunas and Nicholas, making the honour roll among the top 51 beaches in Los Angeles County for water quality. This is a testament to the work of the city and local organisations to protect the area's marine habitat. Malibu is also home to a portion of Areas of Special Biological Significance (ASBS), which are protected coastal areas created to preserve local marine ecosystems. These areas are regulated to prevent pollutants from entering the ocean through storm drains and natural streams, helping to keep the water clean and safe.

The Bad

Despite these successes, Malibu has also faced water pollution issues. Malibu Creek has rated poorly on the River Report Card, with Las Virgenes Creek being listed among the worst freshwater recreation areas in Los Angeles County. Additionally, following heavy rains, toxic pollutants have been known to wash into the intertidal zones, including in Malibu, as a result of burned structures and scorched earth from wildfires. This has led to harmful metals being swept into the sea, posing risks to marine life and potentially impacting human health through the consumption of contaminated seafood.

The Ugly

The Santa Monica Pier, located near Malibu, has been listed as one of the most polluted beaches in California due to high levels of harmful bacteria. While efforts have been made to improve water quality in the area, it continues to face challenges. Furthermore, the SoCal coast, including Malibu, has experienced a harmful algal bloom, which may pose a risk to those consuming locally caught shellfish.

Recommendations

To ensure the safety of beachgoers and swimmers, it is recommended to follow guidelines provided by organisations like Heal the Bay and the LA Regional Water Quality Control Board. These organisations provide valuable information and tools to help individuals make informed decisions about their safety when enjoying the coastal waters. It is also important for the city and local communities to continue their efforts to reduce pollution and protect the area's marine environment.

Malibu's drinking water standards

Malibu has a variety of programs and initiatives in place to ensure that its drinking water meets the required standards. The city is committed to protecting its water resources and maintaining the quality of its drinking water.

One of the key initiatives is the Safe Clean Water Program, managed by the Los Angeles County Flood Control District. This program provides direct funding to cities, including Malibu, to implement various measures to protect and improve water quality. For instance, the city has developed Legacy Park, a 17-acre space that helps keep pollution out of Malibu Creek, Malibu Lagoon, and Surfrider Beach. Additionally, the city has planted a demonstration garden in Bluffs Park, in collaboration with the West Basin Municipal Water District.

Malibu also falls under the jurisdiction of Areas of Special Biological Significance (ASBS), which are protected coastal areas designed to preserve local marine ecosystems. ASBS regulations prohibit pollutants from entering the ocean through storm drains and natural streams, helping to maintain water quality in the region. Malibu is home to a portion of ASBS No. 24, encompassing an area of 11,842 acres of marine habitat.

Furthermore, the city has adopted a Salt and Nutrient Management Plan (SNMP) as required by the State Water Board's Resolution No. 2009-0011. The SNMP aims to manage salts and nutrients from various sources to ensure the attainment of water quality objectives and protect beneficial uses. This includes managing groundwater basins and addressing issues related to salt and nutrient content.

While Malibu has made significant efforts to maintain drinking water standards, there have been some concerns about water pollution in certain areas. For example, Las Virgenes Creek was listed among the worst freshwater recreation areas in Los Angeles County due to its high risk of illness-causing bacteria. Additionally, while two Malibu beaches were ranked among the top 51 in the Los Angeles County Beach Report Card, Malibu Creek received poor ratings in the River Report Card.

To address these challenges, Malibu continues to implement various measures, such as the use of recycled water and stormwater management. The city also encourages residents to reuse graywater, which is gently used water from bathroom sinks, showers, and washing machines, for irrigation to reduce the potential pollution of the environment. Overall, Malibu is committed to working towards conserving and protecting its water resources to ensure safe and healthy drinking water for its residents.

Malibu's water pollution prevention

Malibu has had both positive and negative results when it comes to water quality. While two Malibu beaches, Nicholas Beach and Las Tunas, were among the top 51 beaches in Los Angeles County for water quality, Malibu Creek rated poorly on the River Report Card, with Las Virgenes Creek being among the 10 worst freshwater recreation areas in the county.

To prevent water pollution in Malibu, several measures are already in place. Malibu is home to a portion of Areas of Special Biological Significance (ASBS) No. 24, which are protected coastal areas created to preserve local marine ecosystems. ASBS regulations prohibit pollutants from entering the ocean through private and public storm drains and natural streams. The city has also developed Legacy Park, a 17-acre space that helps keep pollution out of Malibu Creek, Malibu Lagoon, and Surfrider Beach. Additionally, Malibu has adopted a Recycled Water Policy that encourages the increased use of recycled water and stormwater.
