Water Quality Sampling Frequently Asked Questions
Droplet digital polymerase chain response (ddPCR) methodology
1. Where does the County of San Diego pattern seashore water?
County of San Diego, Department of Environmental Health and Quality (DEHQ), Beach and Bay Water Quality Program samples the leisure waterways all through the county, south from the Tijuana border to Trestles seashore to the north. The water is examined for bacterial ranges at roughly 45 seashores all through the county. The program’s mission is to inform the general public of outcomes/well being dangers to allow them to make an knowledgeable determination about the place to swim. DEHQ companions with different companies that additionally share their water high quality pattern outcomes from different seashores. All sampling places might be discovered at sdbeachinfo.com.
2. What do the totally different indicators on the seashore imply?
Advisory – An advisory is issued when the seashore water exceeds State bacterial requirements.
Warning – A warning is issued when the seashore water exceeds State bacterial requirements and there’s a south swell (transboundary flows), which can carry sewage contaminated water.
Closure – A closure is issued when there are sewage or chemical releases, when the Tijuana River is flowing, or when sewage might be detected by water odor or discoloration.
3. When will an advisory, warning, or closure be lifted?
Advisory – An advisory is lifted when water pattern outcomes are inside State requirements.
Warning – A warning is lifted when water pattern outcomes are inside State requirements and south swell (transboundary flows) situations will not be current.
Closure – A closure is lifted when sewage or chemical contamination is not visibly current within the water.
4. Where can I see the present standing of seashore water in San Diego County?
Up to the minute seashore water high quality outcomes are posted on sdbeachinfo.com.
5. Why is the water closed for leisure use?
A water contact closure is issued when there are sewage or chemical releases, when the Tijuana River is flowing, or when there are odors or discoloration of water on account of sewage.
6. What is the ocean water examined for?
The ocean water is examined for Enterococcus micro organism which may point out the presence of quite a lot of pathogens that may trigger sickness, equivalent to micro organism, viruses, and protozoa. For extra info concerning pathogens present in waters contaminated with sewage or runoff, go to our brochure in English, Arabic, Farsi, Korean, Mandarin, Somali, Spanish, Tagalog, Vietnamese.
7. How is the water examined?
The water is examined by utilizing a molecular methodology referred to as digital droplet polymerase chain response or ddPCR for brief. ddPCR counts the enterococcus DNA current within the water pattern.
8. How lengthy does the check (ddPCR) take?
Sample outcomes are reported the identical day samples are collected and outcomes are posted on the Beach and Bay web site: sdbeachinfo.com.
9. Does the brand new check (ddPCR) rely the lifeless micro organism? And can lifeless micro organism make me sick?
The ddPCR methodology exams for Fecal Indicator Bacteria (stay or lifeless micro organism) that are generally present in human or animal feces and are indicators of pathogens that contaminate water and may trigger sickness.

10. What diseases can contaminated water trigger?
The commonest signs of leisure water sickness are diarrhea, pores and skin rashes, ear ache, cough or congestion, and eye ache.
11. How lengthy do you anticipate the will increase in closures within the South County Beaches?
There are many elements that have an effect on water high quality at San Diego County Beaches. One issue that impacts South County seashores are southern swells (transboundary flows), that are extra widespread throughout summer season months and may carry sewage contaminated water north throughout the worldwide border. This sewage contaminated water causes the rise in micro organism ranges and closures at South County seashores. The ocean water is sampled each day at South County seashores.
12. What are the advantages of ddPCR?
The ddPCR methodology is extra delicate than the tradition methodology and impacted much less by environmental elements, permitting it to be extra correct in measuring micro organism and sickness danger, and extra protecting of public well being. The ddPCR methodology supplies sooner, same-day outcomes. When seashores have micro organism ranges that exceed State well being requirements and advisories or closures are required to be posted, DEHQ is ready to elevate them sooner by utilizing ddPCR.
13. What is the distinction between the City of San Diego samples and the County samples, each taken in South County?
The County of San Diego Beach and Bay program focuses on testing ocean water to make sure it’s protected for recreation, utilizing the ddPCR methodology (similar day outcomes). The City of San Diego focuses on testing discharges from handled effluent from the South Bay International Wastewater Treatment Plant, utilizing the tradition methodology (subsequent day outcomes).
14. The water seems to be and smells clear. Is it nonetheless contaminated?
Even if ocean water could look visually clear and never have an odor, it could nonetheless have micro organism ranges that exceed State well being requirements. You can’t see or scent micro organism and there are lots of pathogens present in waters contaminated with sewage or runoff that may trigger diseases. This is why an advisory is issued when the water exceeds State micro organism requirements, and a warning is issued when there’s a south swell (transboundary flows) bringing water north from Mexico.
15. Will I get cited if I select to go within the water when the seashore is closed?
Check along with your native lifeguard. It would depend upon the placement of the seashore and the native ordinance.
