For the protesters, there is no doubt that this plague on local fish is due to the leakage of a broken pipe discovered within the lake.<\/p>\n<p>According to Varna\u2019s mayor, Ivan Portnich, there is no need to \u201cspeculate\u201d over any type of pollution in <a href=\"https:\/\/www.dnevnik.bg\/bulgaria\/2020\/04\/26\/4051656_kak_5_mln_evro_i_hiliadi_kubicheski_metri_fekalni_vodi\/#comments-wrapper\">the area<\/a>. The discoloration of Varna\u2019s bay and river water is a common occurrence due to phytoplankton blooms, which happen yearly. Similar episodes occurred in other regions, such as in Cape Kaliakra and Constanta, Romania, where yellow-brown water discoloration can be observed. Algal blooms are cast as a natural event, in other terms, as they can often happen in the spring and summer due to changes in temperatures and nutrients in the water.<\/p>\n<p><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" data-attachment-id=\"11344\" data-permalink=\"https:\/\/bird.bg\/en\/varna-faecal-water-spill\/boristemkov_twitter_may_2020-2\/\" data-orig-file=\"https:\/\/i0.wp.com\/bird.bg\/wp-content\/uploads\/2022\/04\/%40Boristemkov_twitter_May_2020.png?fit=691%2C640&amp;ssl=1\" data-orig-size=\"691,640\" data-comments-opened=\"0\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"@Boristemkov_twitter_May_2020\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/i0.wp.com\/bird.bg\/wp-content\/uploads\/2022\/04\/%40Boristemkov_twitter_May_2020.png?fit=691%2C640&amp;ssl=1\" class=\"alignnone size-full wp-image-11344\" src=\"https:\/\/i0.wp.com\/bird.bg\/wp-content\/uploads\/2022\/04\/%40Boristemkov_twitter_May_2020.png?resize=691%2C640&#038;ssl=1\" alt=\"\" width=\"691\" height=\"640\" srcset=\"https:\/\/i0.wp.com\/bird.bg\/wp-content\/uploads\/2022\/04\/%40Boristemkov_twitter_May_2020.png?w=691&amp;ssl=1 691w, https:\/\/i0.wp.com\/bird.bg\/wp-content\/uploads\/2022\/04\/%40Boristemkov_twitter_May_2020.png?resize=300%2C278&amp;ssl=1 300w\" sizes=\"auto, (max-width: 691px) 100vw, 691px\" \/><\/p>\n<p>However, two years later, newly disclosed information now contradicts the mayor\u2019s narrative. And while the actual stage of the pipeline\u2019s repair remains unclear, satellite imagery analyses demonstrate increased eutrophication at the time of the leakage, potentially impacting the water with unknown effects in both the short and the long term.<\/p>\n<p><a href=\"#_ftnref1\" name=\"_ftn1\"><\/a><\/p>\n<h2><strong>The pipeline\u2019s mismanagement saga <\/strong><\/h2>\n<p>The pipeline in question was initially laid in Varna\u2019s river as part of a 5-million-euro project titled: \u201cTransformation of the wastewater treatment plant in Asparuhovo district into a pumping station and construction of a transport pipeline below the bottom of the Varna lake\u201d, financed at a 75% rate by the European Union. The construction of this pipe was awarded to the Greek company <em>Sfelinos<\/em> for the benefit of Vik Varna, a public water utility company managed by Varna\u2019s municipality.<\/p>\n<p><em>Dnevnik<\/em>, a local media outlet, has since documented the many irregularities linked to the pipeline implementation in detail; from the incomplete assembling of the pumping system by <em>Sfelinos<\/em>, to delays and incorrect document filings by an expert commission supposed to assess its proper construction.\u00a0 In 2011, upon alleged completion of the pipeline, 25 individuals signed a document stating the pipeline was both buried in the lake bed and ready for operation. However, it was actually aboveground, lying unprotected on the lake bed, <em>Dnevnik<\/em> reports.<\/p>\n<p>Not being buried, the pipeline was eventually damaged in 2015, when a ship stuck it with its anchor. Varna\u2019s mayor was informed of the risks of leakage linked to this incident that same year, according to <em>Dnevnik<\/em>.<\/p>\n<p>The first official notification of a leakage was reported to the municipality in August 2019. It didn\u2019t disclose this information to the public until January 2020. With an estimated daily sewage discharge of around 3.000 cubic metres, this amounted to the spillage of millions of litres of toxic water polluted with faecal matter from the broken pipe &#8211; information left undisclosed to the public for eight months.<\/p>\n<p>While local authorities announced a 1.3 million bulgarian lev fund in order to repair the pipe later that year, and contracted company <em>Hydrostoy<\/em> to fix the pipe within 3 months, the technical difficulty of burying the pipe allegedly delayed the project. When a second and third leak eventually occurred in January and again in May 2021, mayor Ivan Portnich announced that a technical solution to bury the pipeline was still being explored.<\/p>\n<p>It still remains unclear as of today when the full repair of the pipeline will finally be achieved, thus leaving it at risk of other potential leakages during this uncertain period. But what exactly was impact of the leaks so far, and what effects could the next ones have?<\/p>\n<h2><strong>Higher levels of eutrophication during the leaks<\/strong><\/h2>\n<p>In a satellite imagery analysis conducted for the <a href=\"https:\/\/eiforum.org\/wp-content\/uploads\/2022\/04\/Varna_Pollution_Remote_Sensing_Report.pdf\"><strong>Environmental Investigative Forum<\/strong><\/a>, PhD researcher Christina Orieschnig and GIS expert Kristof Horvath were able to visualise chemical characteristics linked to eutrophication levels in Lake Varna from 2016 to early 2021. Remote sensing of the chlorophyll concentration in the lake area allowed them to establish \u201cpattern breaking\u201d values of chlorophyll in 2019 and 2020, demonstrating higher eutrophication levels overlapping with the reported leak.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" class=\"alignnone size-full wp-image-11334\" src=\"https:\/\/i0.wp.com\/bird.bg\/img\/whole_lake2.gif?w=800&#038;ssl=1\" alt=\"\"  \/><\/p>\n<p>Eutrophication is a seasonal phenomenon where water becomes enriched with various nutrients, such as nitrogen and phosphorus, and causes algae to multiply and bloom, typically discolouring the waters. While this phenomenon can occur naturally, it can also be induced or worsened by human activity, notably pollution &#8211; this is then called \u201ccultural eutrophication\u201d.<\/p>\n<p>Upon presenting pictures of other water bodies in a state of eutrophication to the public, inducing that there was no risk of major pollution, mayor Ivan Protnih confused, knowingly or not, two varieties of the same phenomena. It is likely that the wastewater spill could have an impact on eutrophication levels, leading to higher toxicity levels in the water and possibly explaining the tons of dead fish found on the Varna shores in 2020.<\/p>\n<p>Could the tons of dead fish reported on the Varna shore in 2020 be linked with the spill? This question is not easy to answer. But the timing of fish mortality in combination with the known leak and the higher eutrophication levels that very same year provides mounting evidence to support this claim.<\/p>\n<p>This data not only contradicts the mayor\u2019s rhetoric, but also reveals a potential indicator of increased pollution that would have needed to be researched and addressed at the time. This to measure and monitor the extent of the impact of the spill on the Varna lake itself but also subsequently on the bay.<\/p>\n<p>As this could have had &#8211; and still could have &#8211; an effect on local aquaculture, especially for the mussel farms located in the eastern part of the lake, the products of which are destined for both local consumption and export. Mussels filtrating their nutrients from polluted water are more likely to carry <em>Escherichia coli<\/em> bacteria, thus representing a potential health hazard to consumers. With higher eutrophication levels, all shellfish become more exposed to feed on these chemical elements, as well as toxic substances released from the algae.<\/p>\n<h2><strong>\u201cAn environmental catastrophe\u201d with no impact study<\/strong><\/h2>\n<p>Several companies operating in the vicinity of Varna maintain mussel farms, the products of which are destined for local consumption, especially in the eastern part of the lake, which remains the most exposed to eutrophication. Some of these are also destined for export to Romania, France, Italy, Spain, but also Japan, China and the US.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" class=\"alignnone size-full wp-image-11334\" src=\"https:\/\/i0.wp.com\/bird.bg\/img\/aquaculture2.gif?w=800&#038;ssl=1\" alt=\"\"  \/><\/p>\n<p>Which companies export to which markets is hard to establish due to a lack of accurate data on the ownership of these farms and the exact destination of their products on the data portals of the Bulgarian administration. While some of Varna\u2019s biggest players and exporters were asked whether or not these health hazards had been monitored, none of them returned our calls or emails.<\/p>\n<p>\u201cA study was ordered on the wastewater leak impact, but no one has been informed of the results&#8221;, recalls Stella Nikolova, Varna council member from the Democratic Bulgaria party. She remains as convinced of the fish and mussels toxicity as she was in 2020, when she advised Varna\u2019s citizens not to consume them: <em>\u201c8 months of pollution leads to the conclusion that fish and especially mussels have accumulated all the pollution that is possible from the water. Fish died in the lake due to the flowering of algae, which found a &#8220;good&#8221; breeding ground for pollution with faecal water\u201d.<\/em><\/p>\n<p><em>\u00a0<\/em>According to Nikolova, several institutions even seem to differ on the consequences of the event: \u201cthe local Regional Health Inspectorate and the Basin Directorate said that there was no problem with water, while the Institute of Oceanology claims otherwise\u201d.<\/p>\n<p>An expert from the Institute of Fish Resources of Varna expressed concern over an interview request: \u201cThis is such a hot topic. I don&#8217;t know if some scientist will stand up and speak openly\u201d. Asked about what the potential risks could be for speaking out on the matter, the expert, who wishes to remain anonymous, didn\u2019t provide us with more details.<\/p>\n<p>But according to Radoslava Bekova from the institute of Oceanology, it might be too late already: \u201cVarna\u2019s Lake is an ecological catastrophe\u201d, the expert had said in a 2021 interview, adding that the lake was \u201con the <a href=\"https:\/\/www.chernomore.bg\/a\/2-varna\/224001-obshtinata-nyama-novo-iztichane-na-otpadni-vodi-vav-varnenskoto-ezero\">verge of death<\/a>\u201d, due to high pollution and subsequent disappearance of various fish species.<\/p>\n<p>Mayor\u2019s Ivan Portnih office, asked about the consequences of the waste water spill and the release of a subsequent impact study, forwarded our questions &#8211; such as the planned date of the pipeline\u2019s burial &#8211; to the \u201crelevant authorities\u201d. They still remain unanswered to this day.<\/p>\n<p>In the meantime, the pipeline remains exposed to potential leaks for an uncertain period of time, threatening the lake with further pollution in the event of a new leak.<\/p>\n<p>By Alexandre Brutelle, Christina Orieschnig &amp; Adrian Dohotaru<\/p>\n<p><strong><em><u>This story was produced with support from the Journalism Fund EU, Internews\u2019 Earth Journalism Network and Calouste Gulbenkian Foundation (UK Branch)<\/u><\/em><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Warning!
