What was once a thriving ecosystem went dead.

Even after the Regional Water Quality Control Board ordered a cleanup, San Diego Coastkeeper and its allies spent years advocating for a plan that would protect both the environment and the communities through which the toxic waste would be hauled. Finally, in 2013, the cleanup began with the dredging of the southernmost of two sites.

Legal battles among the responsible parties has prevented cleanup of the northern site. On July 22, 2014, the San Diego City Council approved funds for a portion of the cleanup so that it could begin.

Thank you City of San Diego. We're pleased to see the City following through on its obligations to clean San Diego Bay, and we hope that remediation activities will now begin. We attended the council meeting when the council approved the funds so that we could give them our "attaboy." We wanted to let them know that we are watching and urge that no further obstacle stand in the way of a complete cleanup, as ordered by the Regional Board.

Our bay provides sustenance, recreation and industry. It deserves nothing less.

Fertilizer: Go Native. Save the Planet.

Written by

High Tech High Blog Series: Blog 6 of 7

What comes to mind when you read the word “fertilizer?”  Lawns? Farms? Family garden projects? What about water pollution and dead zones?

It’s hard to believe a substance famous for helping plants flourish in one environment can destroy other environments only a few miles away in our lakes, rivers and ocean.

Fertilizers are made up of mostly nitrogen and phosphorus  which, when applied sparingly and responsibly, can create a healthy, strong plant. But when overuse and over watering cause these compounds to flow into other areas, they cause aquatic plants to grow out of control and overrun their delicate ecosystems. 

This is Where YOU Come In. 

native-plants water conservation fertilizerYes, YOU and everyone with a lawn or garden can help end fertilizer pollution.  It takes a lot of work to keep nonnative plants alive in Southern California, because those plants natively thrived in a much wetter, more fertile environment. Instead of breaking out the hose and fertilizer spreader, consider the many beautiful and delicate native plants that love the Southern California heat.

 

 

These plants love the San Diego climate as much as you do:

- Miniature Hollyhock                     - White Sage

- California Lilac                            - Wooly Blue Curls

- Manzanita                                   - Desert Mallow

- Baby Blue Eyes                           - Ian Bush

- Lemonade Berry                          - Milkweed

 - Sugarbush                                  - Scarlet Bugler

And many more native plants

If you can’t bear to part with your beautiful garden, try a natural fertilizer like recycled coffee grounds (free from Starbucks!) before you heap on the chemicals.  Remember, there’s always a natural alternative. You just have to be willing to find it. 

To research and help prevent further pollution, a class of 50+ students from High Tech High school in Point Loma, California teamed up with San Diego Coastkeeper® to conduct the “Oceans Away Project,” a project designed to help inform the public of the consequences of their daily actions.
 

 

 

Heavy metal contamination can come from a variety of sources: the paint on boats, zinc in your tires, etc. Heavy metals contaminate the water and settle along the ocean floor where bottom feeders tend to feed. Though only small amounts of metal is consumed, when larger fish that are higher up in the food chain eat the bottom feeders, a higher concentration of the toxin is then present in their body. This is chain reaction is called biomagnification. Since humans are the top on the food chain, humans are also affected by biomagnification, making it a subtle yet dangerous problem.

Heavy Metal Pollution: Not So Natural Rainbows

Written by
High Tech High Blog Series: Blog 5 of 7
 heavy-metals oil rainbow pollutant toxin street
While driving down the road on a rainy day have you ever noticed the rainbow that flows into the storm drains? Many times you will see cigarette butts, trash and other miscellaneous objects flowing down the road to the storm drains, which lead to the ocean. Many people who drive every day or who have a boat that they actively use, are unaware that there are metals on these vehicles that accumulate in the environment. 
 
Metals such as aluminum, copper, cadmium, zinc, accumulate on the roads, and are washed through storm drains into the ocean during each rain. We call these heavy metals. 
 
Metals in boat paint deteriorate and leach into the water, contaminating surrounding waters. The paint used on the hull of the boat contains copper in order to specifically kill off marine organisms. These metals can bring a great amount of toxicity to the ecosystem that they run into. 
 
In a survey designed by a junior class from High Tech High, over 60 percent of participants thought that they did not or were not aware that they contribute to heavy metal pollution simply by driving or using their boat. 
shipyard heavy-metal pollution toxic ocean 
While the everyday actions of humans are a large source of pollution, waterfront industries where boats are used can be major contributors to pollution. In 2012, the San Diego Bay Shipyards cleanup began as an attempt to tidy up the ocean area in the shipyards due to the amount of pollution that is in the water. Toxic heavy metals have accumulated at the floor of the bay, which can cause mutations and poison the fish that live there. The parties responsible for this are given five years total to cleanup the area. This was a huge step to cleaning up the bay, but more must be done in order to keep our local waters clean. One thing we can do as individuals is to drive less and make sure we properly dispose of all waste in order to help prevent ocean pollution.  
 
To research and help prevent further pollution, a class of 50+ students from High Tech High school in Point Loma, California teamed up with San Diego Coastkeeper® to conduct the “Oceans Away Project,” a project designed to help inform the public of the consequences of their daily actions.
 
 

Sewage is a large environmental problem but not for the reasons that most people think. A big reason why sewage is a problem is because of the excess hormones released in human waste. Only a small percentage of medication is absorbed into the body while the rest is expelled and finds its way to the ocean in sewage. Although wastewater treatment plants are able to remove around half of the hormones, there are still many steps that we need to take to remove the problem completely.

How We Contribute to the Problem

 

We are the problem. 

 

The county outputs 175 million gallons of sewage every day through the Wastewater Treatment Plant on the end of Point Loma. The waste travels out a 4.5-mile tank and is dumped through a 12 ft. diameter pipe into deep ocean water. This is problematic because many believe the pollutants dumped along with this waste are harmful to the environment.

 

The amount of pharmaceuticals and personal care products (PPCPs) introduced to our environment is a leading cause of concern. With the amount of individuals taking prescription and non-prescription drugs on the rise, scientists fear an increase in bacterial resistance.

 

Medicine Can Be Toxic?

Additionally, the increase in the use of birth control, which is among these medications that are not regulated and enters our sewage system at 90 percent effectiveness, is responsible for disrupting our endocrine hormones inducing things like breast cancer, endometriosis, birth defects, abnormal sexual development, lowered sperm counts. There have also been world-wide accounts of the feminization of male fish near sewage treatment plants.

sewage

 

These untreated PPCPs travel through our sewage, surface and ground water, eventually affecting our drinking water and working their way up the food chain through bio magnification.

 

Due to the population increase and a larger consumption of drugs per capita, PPCP use and therefore contamination is on the rise. Even low levels of medicines found in our waterways hurt fish and aquatic life. Especially around these “hot spots,” that is areas close to sewage runoff, researchers have observed negative changes in fish behavior and reproduction.

 

How We Can Help

Learn more about Proper Disposal of Medications and Pharmaceuticals. Also, help the issue by supporting clean and sustainable water through potable reuse projects

 

Supporting new legislation to change sewage treatment plant treatment processes to better remove PPCP is another great way to contribute to the cause.

Plastic, though it was seen as a great technological advancement, has shown the world and the environment it’s dark side. Plastic, which has been used in just about every field, from medicine, to toys, has taken a huge toll on our environment. It washes up on beaches, is ingested by animals, and disrupts ecosystems. But that isn't all. Plastic has a bigger environmental impact than most think. We use oil to produce all the plastic that is used around the world making it so we are manufacturing our own demise

What are the sources of pollution?plastic-bottle-of-water-s

To understand the problem with plastic pollution, a group of students researched the common sources and effects of plastic pollution. As a result of their research, they found that 90 percent of the ocean’s trash is actually plastic. Research shows that 80 percent of the marine debris, including plastics, comes from land while 20 percent comes from boats. The most common sources of this pollution are disposable plastics like bags and bottles, and fishing gear that come from ships. 

What are the effects?

The students discovered that the problem with plastic pollution is that the plastics last forever-this means the plastic continues to pollute the environment at every stage of its existence. Because of this, the ecosystem of the ocean, animals, and people are affected negatively. Animals can accidentally ingest or get entangled in plastics, leading to fatal results, while the marine debris in the ocean can harm the aquatic vegetation or suffocate coral.

dsc 2788-sHow can it be fixed?

After finding out how plastic pollution can have negative impacts on the environment, the students moved on to figuring out how people today could fix the problem:

1. Find alternative to plastics, like reusable bags and water bottles

2. Throw away or recycle plastics and trash properly rather than litter

3. Participate in beach cleanups

                                                                                 4. Support single-use plastic bag bans

 What has been done so far?

 Beach cleanup data from Coastkeeper beach cleanups suggests that a lot of the trash that was picked up was plastic. Because plastic is non-biodegradable, it will only keep breaking down into microscopic pieces in the ocean, making it much harder to actually clean up all of the plastic in the ocean. Also, the borken down plastic begin to resemble plankton, a common food source for marine life. So by completing these beach cleanups every year, more of the plastic that ends up on the beach can be picked up before it ends up in the ocean to break down and further pollute the environment. 

To research and help prevent further pollution, a class of 50+ students from High Tech High school in Point Loma, California teamed up with San Diego Coastkeeper® to conduct the “Oceans Away Project,” a project designed to help inform the public of the consequences of their daily actions.
 

 

Watershed Management PlanASBS Blog 1

The City of San Diego, University of CA, San Diego/Scripps Institution of Oceanography (UCSD/SIO), and San Diego Coastkeeper make up the La Jolla Shores Coastal Watershed Management Group. Their priority is to manage urban runoff and protect the health of the two adjacent ASBS's in La Jolla (see picture right). 

In 2008 the group authored the Watershed Management Plan that was developed from a series of stakeholder and project partner meetings. Experts from the fields of urban runoff management, ocean and environmental science, data management, and public participation were consulted to develop a holistic program to address the complex issues and California Ocean Plan standards associated with an ASBS.

La Jolla Shores has an ASBS Protection Implementation Program that represents the initial stage of ASBS protection. It supports four essential and interactive components of the Watershed Management Plan, including:

  1. Urban Runoff Management - addresses needs to reduce watershed pollutant impacts and the prohibition of waste discharges into an ASBS
  2. Ocean Ecosystem Assessment - addresses the need to identify health of the resources, impact of runoff, and effectiveness of management measures
  3. Information Systems - addresses the need to develop resource management tool serving variety of end users
  4. Public Participation - addresses the need to engage public in protection and management of resource

By incorporating all four components, the two La Jolla Shores ASBS will be protected by reducing urban runoff pollutants from discharges and establishes important assessment and monitoring tools. The focus is to reduce or eliminate the primary sources of water quality threats. This plan will provide multiple benefits by protecting not only the ASBS; it also includes high use public beaches and two Marine Protected Areas nearby.


Incorporating Information Management into ASBS Management

Integrated information management systems are a critical tool to efficiently assess and manage regulatory programs. Information management systems can display data in the interrelated language that biological-physical-chemical processes present in the watershed and marine environment. These data can then be assessed and available to a wide range of users that span both regulatory and non-regulatory based data collection efforts.

Our goal was to design a modular problem driven application that builds upon different standards and protocols.
We strived to emulate existing ocean observing systems web portals for ease of navigation and familiarity. Utilizing open standard formats and protocols enables access to varying structures and distributed data sources. Since some of the data shown on the website is derived from other sources, the goal has been to access services or data directly instead of hosting copies. This format allows for varying data types enabling a customized portal.

The online tool that is entering its' beta testing mode now, was designed to establish the infrastructure needs and generate a conceptual design that is required for long term assessment of ASBS performance and related management decisions. The system will expand upon the current information management framework developed by UCSD/SIO for the La Jolla Shores Coastal Watershed Management Plan. Local and regional information sharing initiatives are promoted, and support low impact development (LID), water conservation, and public engagement through outreach and data visualization. The end-product will be to develop a usable information system for a range of users.
