Haley Cahill was our education intern from January to June 2015. She is majoring in Environmental Studies at the University of San Diego and believes the answer to improving many of the threats that our environment faces, starts with education. Haley helped us to bring Project SWELL into San Diego Unified School District classrooms.

“Do you talk about gross stuff?” was the first question I received as I set up my presentation for these elementary school kids. I immediately replied with a “yes” and the 5th grade boy replied with a fist pump and an enthusiastic “Yes!”

I laughed, but I was thrilled to see these kids excited about pollution. As an education intern, I attended Bird Rock Elementary’s inaugural STEAM (Science, Technology, Engineering, Art and Math) Discovery Day, to try and ignite a passion for protecting and restoring our water in our next generation of leaders.

I love talking to students, it’s vital to instill in them why we need to care about our environment. Attending allowed me to see that Project SWELL, our water science education curriculum, is making a huge a difference! In each group of of kids, at least a few were already familiar with some of the material I was teaching. They would yell out an answer, or point out that they noticed pollution the last time they were at the beach.

As I looked out at all the faces I asked if anyone had ever been to a beach clean up. I was pleasantly surprised to see that over half had! These kids are already aware that their environment needs to be taken care of if they want to keep it healthy so they can continue to enjoy it as they do now. And the best part? They are excited to do it!

I can’t wait to meet other students as eager to learn as these kids were!

20 Years is Celebrateable

Written by Megan Baehrens

It’s been twenty years since two gutsy water lovers took action to stop the toxic dumping that was slowly killing San Diego Bay. In 1995, they created San Diego Baykeeper and

And as the need became apparent, we turned our attention countywide. Now we’re known as San Diego Coastkeeper–the region’s water quality and water supply watchdog. We’ve grown from a team of two into a movement of thousands of volunteers, members, sponsors and partners passionate about working together to make San Diego more fishable, swimmable and drinkable.

Today we bring together science, education and advocacy to address the region’s most pressing concerns.

bruce1That is celebrateable.

Take a look back at our 20-year timeline of water victories and check out our top accomplishments page to reminisce about all the water wins of the past twenty years.

And take a look ahead. We are already knee-deep in the next twenty years of fighting for our region’s health.

  • We are back in San Diego Bay, bringing south bay industrial polluters to task for dirtying our water.
  • Our water quality lab is investigating impacts and root causes of the death-by-one-thousand-cuts that strangles our waterways with urban runoff.
  • And we are fighting like mad to ensure that the urgency created by statewide drought fuels common sense conservation and innovative new water management practices like recycling and stormwater capture, but doesn’t justify bad choices like energy-hungry desalination.

Whether you’ve been with us since the beginning or are just joining us now, we want you to be part of this movement. Attend our Coastal Champions Awards Ceremony on June 8 and our Seaside Soiree in October. We’re proud to share this celebratory year with you and in honor of you. We celebrate 20 years of victories, but more than that, we celebrate the 20 years to come.

San Diego Coastkeeper stands on the shoulders of those who came before us. And we are leaning in to lift up those who come after us. But for today, you, I and everyone in this movement stands together for fishable, swimmable, drinkable water throughout San Diego County.

Let’s get to work, Megan

The Ocean Enthusiasts of Coronado Middle School

Written by Sandra J. Lebron

Screen Shot 2015-06-09 at 9.05.01 AMAn important step in protecting and restoring fishable, swimmable, drinkable water is making sure we have informed and passionate leaders in the next generation to which we can hand off our mission. Since we’ve started environmental education outreach programs like Project SWELL, we haven’t had a shortage of hope for the future of San Diego’s water. We continue to be inspired by our future leaders’ passion for water. This is one of our favorite stories. 

At Coronado Middle School, a teacher challenged her eighth grade students to choose their own topic for a research project about what human impacts are detrimental to our environment. This class, aptly named themselves the Ocean Enthusiasts, really wanted to focus on keeping the ocean they love clean. The students came up with an abundance of topics including the impacts of plastic bags, sewage waste, the current drought and marine pollution. At the close of their research, each created a video, poster or other illustration that showed the most important lessons they learned from this project. 

These students, after working on these projects, take away not only the information on how harmful our effect on the environment can be, but also the drive to do something about it. They reached out to San Diego Coastkeeper to see if we could use what they worked so hard on to educate others. This class and the teacher, Mrs. Landry, can now act as an example to other students and teachers. This is a great way to get students involved and excited about the environment and water quality. Both are intertwined and it is necessary to impose the importance of both of them to the younger generations.

Water Quality 2014 – More Impacts from the Drought

Written by Meredith Meyers

Check out San Diego Water Quality for 2014

In 2014: Looks like San Diego’s drought affects more than water quantity—and we have the data to show it.

san diego watershed scoresWe proudly announce the results of our 2014 Water Quality Monitoring efforts, and a few key takeaways from this year’s data. One of the most striking trends we see is that our third consecutive year of drought (7.77′ total rainfall in 2014 compared to the 10.34″ average) has likely contributed to inland water quality issues.

One issue likely related to drought conditions that our 2014 data revealed is low dissolved oxygen concentrations. Turns out that 30 percent of our inland water quality samples that we gathered from across the county measured below healthy levels. Sadly, when dissolved oxygen measurements reach levels this low, aquatic life dies. In April 2014, we even ran across a fish kill in San Luis Rey from just this.

San Luis Rey - fish kill

Another trend related to low water levels that shows in our 2014 numbers is that fecal indicator bacteria levels (especially Enterococcus) were a concern across all watersheds. Of our samples in 2014, 57 percent of the Enterococcus samples exceeded healthy standards, and eight of nine watersheds scored marginal or poor for their E. coli scores.

What does this mean?

Enterococcus indicates whether water conditions are safe to swim, most commonly used to measure healthy conditions of salt water. Since all of our inland waterways empty to the ocean, it’s not a good sign that we’re measuring so much Enterococcus in our fresh waters. If you don’t know, this means that the water has pollutants in it that can cause staph infection, ear aches, stomach issues, rashes, eye infections, cysts, and others—just to name a few.

To be accurate, there can always be an amount of Enterococcus in our water due to natural causes (aka bird poo), and those may not cause human health impacts. But the levels in our data are so high, we have major concerns. To illustrate the degree to which this is a problem, our December sampling event took place on the day after a heavy rain, and every single sample collected far exceeded healthy levels acceptable for Enterococcus and E. coli. This is why the County’s Department of Environmental Health closes the beaches countywide after it rains–water quality is extremely poor.

These sort of data sets also raise a question that we can’t answer: Is the drought reducing water levels so much that shallow, slow-moving and warm streams create a breeding ground for Enterococcus and E. coli? More so than any other recent year, a lot of our sites even dried up in 2014 so that we couldn’t gather samples. But given our analysis and the increase in water quality impacts shown by fecal indicator bacteria, we’re curious to explore this question. Unfortunately, the data that we collect can’t help us answer this question.

As you can see in the countywide map, Water Quality Index Scores grouped the map’s color-coding into three sections: fair scores in the north, marginal in the middle and poor in the south. We’re not surprised to see this as we think that these groupings of scores relate to the various land-use types and density of development within the watersheds. The north has more open space and agriculture, the middle has more density and developed land area and the south struggles with cross-border water quality management challenges.

We encourage you to click through to each of our nine watersheds to learn more about water quality scores unique to each. This year, San Diego’s coastal watersheds ranged from fair to poor according to our Water Quality Index scoring system.

  • Two watersheds scored lower than they did in 2013 (Los Peñasquitos and San Diego—they were good last year)
  • One watershed improved its score from 2013, going from Marginal to Fair (Carlsbad)

We’re thankful for our 194 volunteers who gave a total of 1,888 hours. And we’re encouraged by our 83 newly trained volunteers from 2014.

Water Quality 2014: Tijuana Watershed

Written by Meredith Meyers

Tijuana water quality 2014

Tijuana water quality

Water Quality Index Score: 12, Poor

Let’s acknowledge that we only gathered one sample from the Tijuana Watershed in 2014. Thankfully, the Tijuana-based sewage treatment plant handles and purifies 50 million gallons of river water every day, but it can’t handle wet weather flows. So, when it rains, the operators divert the river flow without treatment, and that’s when we can sample the river. This is also why Imperial Beach beaches are frequently closed during the winter.

Our only sample in 2014 follows a massive rain event in December. That sample showed:

  • Bacteria levels were extremely high – even diluting the sample 100 fold, the concentrations were still higher than our test kits can measure
  • Ammonia, nitrate, and phosphorus levels were off the charts
  • Volunteers had to sludge through very sticky, smelly mud to collect the water samples – thanks!

This watershed presents a lot of cross-border collaboration and love to truly understand and solve the interconnected water quality issues. We’re looking for passionate volunteers to get trained in water quality monitoring so they can champion efforts in this challenging watershed. What are you waiting for? Sign up to get trained!

Water Quality 2014: Otay Watershed

Otay water quality 2014

Otay water quality 2014

Water Quality Index Score: 53, Marginal

If we’re going to call Los Penasquitos the average watershed example of San Diego County, we’re going to call Otay Watershed the most consistent watershed in the county. Its consistently high numbers showed:

This also means that this wasteshed runs consistent with our theory that the region’s drought has affected water quality in addition to water quantify. At no point in 2014 did the data from Otay Watershed put it into healthy ranges for fecal indicator bacteria or nitrates. But, consistent with all the watershed scores in December, Otay Watershed’s scores did worsen after the rain event.

We loved hearing that our volunteers in this watershed also consistently spotted dragonflies, crawfish, and herons while sampling.

Water Quality Index Score: 62, Marginal

Our data in Sweetwater Watershed showed:

Again, another watershed indicative of extremely low water flows creating high nutrient levels and low oxygen levels — so low that the river is near depleted of oxygen for many of the summer months.

Why should we care? Our volunteers also spot turtles in this watershed, which depend on the river for their livelihood.

Water Quality 2014: Pueblo Watershed

Written by Meredith Meyers

Pueblo water quality 2014

Pueblo water quality

Water Quality Index Score: 64, Marginal

A few key takeaways from our Pueblo Watershed data:

As this watershed is home to Chollas Creek, one of San Diego’s most urban rivers, these results aren’t unexpected. This creek is infamous for drying up, also, so our dataset is missing many samples throughout the year. In fact, more sites went dry this year than any other year in Coastkeeper’s recent sampling history here.

We think all signs point toward poorer water quality than shown with the samples that we could collect, and we wonder with more flow would the Water Quality Index Score have returned a Poor rating?

Pueblo Site black water filterThe high phosphorus and ammonia results belong in the nutrient category, which is common in urban areas with regular use of fertilizers and pesticides on outdoor spaces. An extreme example of this sort of pollution occurred in November, when our volunteer team encountered very black water with a foul odor .

That water sample exceeded healthy standards for nitrate, ammonia, phosphorus, and both types of fecal indicator bacteria. It’s dissolved oxygen was also extremely low. At first, we thought the black water could have been sewage, but an inspector from the city ensured no sewage lines travel to that location. Turns out, it was just really bad water quality. Our guess? Rotting organic matter or some other industrial waste. As indicated in so many of the other watershed data, the low flows and higher-than-normal water temperatures turned Cholla Creek into the perfect breeding ground for rotting vegetation.

Water Quality 2014: San Diego Watershed

Written by Meredith Meyers

SanDiego water quality 2014

SanDiego water quaity

Water Quality Index Score: 62, Marginal

2014 was not a good year for the San Diego River. It dropped two levels on our Water Quality Index score, moving from Good in 2013 to Marginal in 2014, and giving it the dubious honors of being the only watershed to get worse. Key data takeaways include:

This is an excellent example to demonstrate how the region’s historic drought conditions impacted water quality in our inland waters last year. I grew up playing in the water at the old mission dam, which has one of our sampling sites nearby, and I can’t recall the water levels ever reaching the lows that we saw this year

All three bullet points in the San Diego Watershed data relate to one another and differently demonstrate high amounts of nutrients in the river. To say the least, this river is out of balance.

High nutrient levels, which often start as fertilizers on our lawns and gardens, cause algae and duckweed growth, which ultimately deplete oxygen levels and kill marine life. We think the low water levels contributed to slower flows and warmer waters, creating the perfect breeding ground for explosive algae growth in the San Diego River. And greatly impacting water quality.

Water Quality Index Score: 76, Fair

Well, here it is: the most typical, average watershed in San Diego County in terms of water quality pollution and health. Our data in this watershed did not change dramatically from the year previous, nor did it produce any intriguing results this year.

It’s typical.

The end point for this watershed, the Los Penasquitos Lagoon, has an official “pollution diet” in place for sediment, which means it’s a known problem here. We continue to monitor this closely.
