cyanobacteria treatment in lakes

As I mentioned, cyanobacteria uses light to photosynthesize. An example of watershed management is remote livestock watering. Solutions In 2016, homeowners around Long Lake voted to … Thank you to everyone who attended the February 23 meeting. The decomposition processes of accumulated cyanobacteria can release large amounts of organic carbon and affect the carbon cycling in shallow eutrophic lakes. Elements like phosphorus and nitrogen that cyanobacteria require occur naturally in the environment, but usually not in quantities that support a … Globally we are all experiencing the effects of global warming. Because of Lake Michigan's excellent water clarity, it has been observed … Instead of the man who planted trees become the woman who planted aquatics! Become the annoying neighbour who makes friendly suggestions to the lawn mowing landowner down lake from you. Melissa DeSimone, Paul Sniadecki, and Lon Nordeen, Michigan Lakes and Streams Association.Moderator: Paul Hausler. Staging and treatment occurred the first week in April 2016. Monitoring and Evaluation of Cyanobacteria in Lake Champlain (Summer 2002). Cyanobacteria, also known as blue-green algae, have become a growing concern in the drinking water world. Like red tides, cyanobacteria can grow and accumulate, or bloom, when environmental conditions such as light availability and temperature are favorable. Chemical treatment is the most commonly used method, which is also the most dangerous to the environment. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. are the nutrients coming largely from internal sources (e.g. Cyanobacteria & Cyanotoxin Mitigation For Lakes, Reservoirs and Ponds Whichever the primary use of a waterbody (raw water drinking source, recreational, small lakes & ponds, stormwater, etc), the key component for effective cyanobacteria (blue-green algae) control is to actively circulate just the upper water of the lake known as the epilimnion. A: Blue green algae, or cyanobacteria, can multiply quickly in lakes with high nutrient levels, particularly when the water is warm and the weather is calm. Reducing nutrient build-up (eutrophication) in lakes and reservoirs, especially by better management of wastewater disposal systems and control of pollution by fertilizers (including manure) from agriculture. Blue-green algae, or cyanobacteria, can produce microcystin toxin, a threat to human and animal health. Algae blooms are spoiling our lakes and clogging our water treatment plants. Microcystis, Aphanizomenon, Anabaena, Osicllatoria, and Nostoc are common strands. Share driving. What the scientists have been warning us about for decades is now happening; we are living in a changing climate that is becoming increasingly harsh and unpredictable. 2007. It is also known that some plants will take up certain nutrients efficiently. These toxins may kill animals that drink the water. It is therefore critical to control the growth of cyanobacteria in any water supply used for human or animal consumption. MORE INFORMATION: Grants for Freshwater Algae Management. If needed, replenish fluids and electrolytes. Drive your car less, walk and cycle more. Watzin, M., A. Shambaugh, E. Brines, and G. Boyer. Highlights Addition of dilute H 2 O 2 to a lake caused the collapse of a cyanobacterial bloom. Therefore, it could be concluded that alum treatment with maximum dose (48 mg L(-1) as AI) is not suitable for removing cyanobacterial bloom without the release of cyanotoxin in reservoirs and ponds. This population explosion causes “blooms” of blue-green algae that turn the water green, often with floating layers of scum. Some HABs produce toxins (known as cyanotoxins). Copyright © 2020 Canadianpond.ca. Unfortunately it is not a simple task to test for toxins in the water. For ingestion of contaminated water or seafood: Stop the exposure by avoiding contaminated seafood or water. y Properly maintain your household septic system. In absence of light, the bacteria will die off in a few days. The blue green algae bloom like warm water temperatures, so until we change our output of greenhouse gases on a global scale, one car or action at a time, your pond will likely experience more frequent and persistent algae bloom problems in the future. Monitor and sample the recreational waters to confirm or modify the notification until two consecutive tests show the cyanotoxins concentrations are below safe levels and visual signs of the bloom are gone; notifications can be lifted once cyanotoxin concentrations are below safe levels. Scope of the Problem. (Public domain.) Cyanobacteria and cyanotoxins in drinking water supplies may also be mitigated during the treatment process. Educating the staff in the health and water supply sectors, as well as the public, about the risks of drinking, bathing or water sports in water likely to contain high densities of cyanobacteria. As a result, the release of massive amounts of cyanotoxins occurs. Cyanobacterial toxins (microcystins) were rapidly degraded. Some cyanobacterial HABs, or cyanoHABs, can produce toxins. The number of such reports, particularly the occurrence of cyanobacteria or blue-green algae blooms and concern over the possible presence of algal toxins such as microcystin, appear to have increased in recent years. Don`t wait for the government to save our planet, you start and maybe the institutions will follow. Two systems were installed in a lake used for water skiing and fishing, and two additional unites were installed in June 2017 in a lake used for sailing. Nutrient sources include phosphorus, nitrogen, animal waste, fertilizers, soil particles, and silt. Eukaryotic plankton and macrofauna were largely unaffected by the H 2 O 2 treatment. After last week’s massive cyanobacteria (blue-green algae) bloom in Lake Mendota and smaller (but no less unpleasant) blooms reported in Lake Monona and Waubesa, we received all sorts of questions on what causes these blooms, if they are dangerous and how to stop them. Long Lake was recorded to have cyanobacteria blooms in 2013, 2015, 2016, 2017 and 2018. Two systems were installed in a lake used for water skiing and fishing, and two additional unites were installed in June 2017 in a lake used for sailing. Institute carpooling where you work. A blue green algae bloom can also lie below the surface of the water. from phosphorus release from sediments) or from external sources (e.g. The most common cyanobacteria toxins are Anatoxin-A, a neurotoxin, and Microcystin, which affects the liver. ABSTRACT This work describes the appearance of a … Greater nutrient loading and warmer weather have led to an increase in the occurrence and magnitude of harmful algae blooms from cyanobacteria in the Great Lakes, throughout North America, Australia, and the world. There are no specific antidotes for cyanobacterial toxins. Blue Green Algae in Ponds. This approach of global action, protecting the watershed and using the latest benefits of biology + technology is showing exciting results among our clients. The best plan to minimize cyanobacteria, algae, and aquatic plant problems incorporates good watershed management. This population explosion causes “blooms” of blue-green algae that turn the water green, often with floating layers of scum. Our approach to aquatic management is two-fold: always take great care to manage the watershed properly as a preventative measure and when the situation is so bad that the health of wildlife is at risk or the enjoyment of your lake is impeded, take immediate action that involves the benefits of biology + technology, like adding much needed oxygen through aeration. The Global Water Research Coalition issued a guidance manual to help waterbody managers and drinking water treatment plant operators understand the importance of cyanobacteria and the toxins they produce; assess the risks associated with a particular water body; develop a monitoring program; and, implement management procedures at affected water bodies and treatment plants. June 24, 2015 By Simon Breese, P.Eng., AECOM The islands do other things as well: they provide shade for fish, they provide habitat above and below for birds and fish, they are attractive, they can be used to protect shoreline from the wave action of boats, they can deter boat traffic much like a buoy would and they make a great community project. Its growth is first recognized as a “pea soup” green appearance to the water. Some species of cyanobacteria produce liver or nerve toxins. Certainly, never fertilize your lawn; you are just contributing to poor water quality for everyone. Intravenous with electrolytes; Seizure medicine; Oxygen therapy; Mucosal protectants; Vitamins; Antibiotics; Nutritional supplements; Medication to bind bile acids When aquatic weeds are left to grow uncontrolled, they can produce issues such as interference with fishing and other watersports, lower dissolved oxygen levels, intrusion with water flow, harm fish and other wildlife, and even disrupt boat traffic. To help reduce cyanobacteria from forming: y Use only the recommended amounts of fertilizers on your yard and gardens to reduce the amount that runs off into the environment. Station d'Hydrobiologie du lac du Bourget, 73103 Aix-les-Bains, France. Therefore, lakes with a high proportion of this strain of hybrid watermilfoil should not be targeted for control with 6ppb fluridone. This microscopic bacteria can also grow in backyard fountains, garden pots, birdbaths, and anywhere water is stagnant. Plan your car trips for shopping with other outings so you use the car less. Strict regulations were put in place for water treatment and industrial water and the removal of phosphorus from that water before it was allowed back into the lake. 2. Blue-green algae, also called cyanobacteria, is found in fresh and brackish water of ponds and lakes. Yet, they can still be found today in all of Florida's freshwater and brackish habitats – lakes, rivers and estuaries. If possible, remove these surfaces, or plant berms around them so that the plant roots can take up excess moisture, and the soil can absorb the water. The most dominant blue-green algae in the Great Lakes is microcystis, which produces a liver toxin and skin irritant called microcystin. Therefore, even after effective copper treatment, cyanobacteria and algae problems will recur at a later date. Blooms can form when cyanobacteria, which are bacteria that grow in water, multiply quickly and form “scums” or “mats” on the surface of the water. A recent review (Hyenstrand et al. For streams that cross your land and enter the lake, do the same thing, plant indigenous aquatic plants in and along the stream and never mow up to the stream edge. Control Cyanobacteria concentration Four solar-powered algae control systems were installed in the Aquadrome in Rickmansworth (UK) to control the cyanobacteria concentration in two lakes. Some algal blooms can contain cyanobacteria, often referred to as blue-green algae. Exchange of water from a well or other source that does not have an algae bloom will dilute the algae in the pond. Cyanobacteria are some of the Earth’s oldest organisms, with fossils dating back 3.5 billion years. y Maintain a buffer of natural vegetation around … Here are some answers to a few of the frequently asked questions. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. The alum treatment was applied from a barge on the lake. Download a pdf of our cyanobacteria FAQs.. What is cyanobacteria (blue-green algae)? Performance & security by Cloudflare, Please complete the security check to access. • In contrast, our fluridone assay identified several strains of watermilfoil that appear susceptible to 6ppb fluridone, and therefore lakes dominated by these strains would likely respond well to fluridone treatment. 2. Cyanobacteria were present in 98 percent of the lakes studied. This approach worked initially and there was a reduction in the size and distribution of cyanobacteria blooms on Lake Erie. In the US, from 2007-2011, HABs were reported to have caused: 183 cases of human illness; 38 dog … If your goal is to keep your lakeside property enjoyable and your lake safe for recreation, start now, mobilize your neighbours and lake community; take it upon yourselves to make the necessary changes, so at least you can say you tried your best. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Sell one vehicle. Other methods such as remedial dugout coagulation treatment will remove phosphorus from the water column, and can minimize the potential growth of cyanobacteria. Bioaugmentation and natural beneficial bacteria, Bubble Tubing®, Fine Bubble Linear Diffuser. This document outlines a protocol for evaluating potential health concerns related to the presence of cyanobacteria (blue-green algae) in Massachusetts recreational freshwater bodies. Under certain conditions, they can multiply quickly, creating a highly concentrated area known as a cyanobacterial harmful algal bloom, or cyanoHAB. 6th International Conference on the Conservation and management of Lakes – Kasumigaura, Japan 1995. The treatment added the medium cyanobacteria biomass (235 g) presented the lower DOC/total dissolved carbon ratio than the high cyanobacteria biomass associated with the lower mineralization from DOC to DIC. Regardless of where it’s found, blue-green algae is dangerous. So managing local watersheds properly is the key to great water quality. In Maine, three lakes in particular-Lake Auburn, Georges Pond (located in Franklin), and East Pond in the Belgrades-made algae-related news this summer. Control Cyanobacteria concentration Four solar-powered algae control systems were installed in the Aquadrome in Rickmansworth (UK) to control the cyanobacteria concentration in two lakes. It grows on submerged rocks, logs or other hard surfaces. Think globally act locally. This growing imbalance has important implications for aquatic ecology that remain poorly considered and understood. It can look reddish-brown or bluish-green in appearance and tends to show up slowly in small clumps/patches before quickly spreading and covering your aquarium. Floating, Blue-Green algae cannot be mechanically or physically controlled, except by replacing the pond water. More Info & Photos of Blue-Green algae. The floating islands we sell have great potential for assisting in the removal of soluble phosphorous from the water. Treatment will include the following as needed, depending upon the type of cyanobacteria involved. Some types produce toxins which release into the water when cyanobacteria die and break down. 2003. At that time, Lake Niegocin was highly eutrophicated, but with the modernization of the water treatment plant in Giżycko in 1995, the trophic status of the lake gradually decreased 38, as did the phytoplankton biomass and share of cyanobacteria in it 8, 35. Our lovely corner of the world has been hard hit by numerous blue-green algae blooms over these past few summers. Twelve popular lakes … CyanoLakes provided up to three-weeks advance warning of cyanobacteria blooms compared with routine in situ monitoring [and is] invaluable in providing sufficient time for operational decision making in preparation for severe bloom conditions and the accompanying microcystin or taste and odour contamination treatment issues While cyanobacteria can grow really fast, it can die off fast too. Lake Auburn experiences high levels of the cyanobacteria Gloeotrichia echinulate in the summer, and after a large fish kill in 2012, has been under close scrutiny for any changes in water quality. If not treated properly, it can contaminate drinking water. The contamination is visible: When there is a cyanobacteria bloom, portions of the lake change colors, he says. The toxins can present a potential hazard to people and their pets. If so, this is detrimental for water quality because short grass cannot absorb excessive nutrients such as phosphorous, like a lush band of shoreline plants and aquatic plants can. Panajachel municipality Mayor Abraham Mayén, referring to the costs associated with wastewater treatment plants. Whether you consider yourself bold and influential or timid and conflict averse, this session is for you. MONITORING A TOXIC CYANOBACTERIA BLOOM IN LAKE BOURGET (FRANCE) AND ITS CONSEQUENCES FOR WATER QUALITY Jean-F. Humbert 1*, Gérard Paolini2 and Brigitte Le Berre 1. Cyanobacteria (sometimes called blue-green algae) occur naturally in fresh- water. In freshwater systems, cyanobacteria (also called blue-green algae) are microorganisms that can produce HABs. What we need to do is to take a good hard look at our own practices and evaluate how they might possibly contribute to the problem of blue green algae blooms. Well-designed, continuous, year-round diffused aeration at the bottom of the dugout can minimize the natural recycling of phosphorus from the sediment. In this paper we follow two independent approaches to show that this situation is likely to be one of two alternative stable states of the algal community. • Here are a range of techniques to deal with the problem. What can I do, you ask? Any water sample taken for cyanobacteria identification should be kept cool and analysed within 24 hours of being collected. Cyanobacterial toxins in lakes, ponds, and dugouts in various parts of the world have long been known to cause poisoning in animals and humans; one of the earliest reports of their toxic effects was in China 1000 years ago (Chorus and Bartram, 1999). Each of these acts as a fertilizer for algae and aquatic plants. Cladophora is a green algae found naturally along the Great Lakes coastlines. The 2016 alum treatment reduced phosphorus levels in the lake, limiting cyanobacteria (blue-green algae) blooms and improving recreational use of the lake. We are also finding the latest technologies that mimic nature are very effective in problem situations; such is the case with using beneficial bacteria and floating islands. In this way the islands allow natural processes to remove excess phosphorous. INRA, Station d’Hydrobiologie, BP 511, 74203 Thonon-les-Bains cedex, France. It does not produce toxins the way blue–green algae can. Typically, ponds and lakes have very high phosphorus concentrations which serve as a nutrient for cyanobacteria, algae, and aquatic plants. Copper treatments are a temporary solution to problems with cyanobacteria. Plant indigenous shrubs along your shoreline and avoid lawn mowing as much as possible. Moreover, alum treatment caused damage to cyanobacteria-lysing organisms and microcystin-degrading bacteria, as well as to Microcystis cells. They are sometimes referred to as blue-green algae, but they are not algae – they are bacteria. For the pond owner or resident living along affected lakes, do a small watershed checklist and action plan, to see how your own actions are contributing to poor water quality in your pond or lake. Integrated Environmental Assessment and Management. Remediation of these problems requires understanding the mechanisms favouring Cyanobacteria dominance in lakes. Copper treatments are a temporary solution to problems with cyanobacteria. Blue-green algae on the Kansas River. H 2 O 2 treatment is an effective method for selective removal of cyanobacteria. Black-Out Treatment. Screaming at town council meetings will accomplish less than taking action yourself and spreading the word through your own positive ways. Cyanobactéries et cyanotoxines dans l'eau potable et l'eau récréative Définition et description Taxonomie, morphologie et écologie1 Les cyanobactéries sont des bactéries photosynthétiques qui possèdent de la chlorophylle. Prairie ponds and lakes experience prolific algae growth because the water is nutrient-rich. Addressing Public Health Risks for Cyanobacteria in Recreational Freshwaters: The Oregon and Vermont Framework. Certain conditions – low water levels, limited water circulation, increased heat and light, among other factors – can cause cyanobacteria to bloom and, in some cases, release toxins. Blue-green algae bloom with too much phosphorous. Your dog will be admitted to the hospital, and a treatment protocol will begin. Elles sont couramment appelées « algues bleues » ou « algues bleu-vert », bien que taxonomiquement ce ne soient pas des algues2. Some of that cyanobacteria – which looks like blue-green algae on the water – can produce a toxin called microcystis. Treatment for People Who Have Been Exposed to Cyanotoxins. Under the right conditions they form large accumulations referred to as blooms. PREDICTION IN 12 LAKES IN KOSCIUSKO COUNTY, INDIANA Nathan S. Bosch1 and Seth A. Bingham: Lilly Center for Lakes & Streams, Grace College, Winona Lake, IN 46590 USA Kris Farwell: Science and Mathematics Department, Grace College, Winona Lake, IN 46590 USA ABSTRACT. Due to the concentration differences of DIC at water-sediment interface, the main migration of DIC from pore water to overlying water occurred in the treatment without added cyanobacteria … Deep down, the water is brown, but toward the surface it is red. Many schools have launched islands as special environmental projects. The Kansas River is a primary source of drinking water for about 800,000 people in northeastern Kansas. Commonly called blue-green algae, it is actually a type of bacteria that relies on photosynthesis and is a common inhabitant of surface waters, including lakes and ponds. Contrary to the high diversity of cyanobacteria occurring in these lakes ... Changes in the trophic state of Lake Niegocin after the modernization of a local wastewater treatment … Treatments include aeration, pumping surface scum Your IP: 134.213.27.96 Cyanobacteria (Blue-Green Algae) Cyanobacteria, also known as blue-green algae, are naturally found in fresh water in the U.S. and in Lake Champlain and other Vermont waters. Cyanobacteria (also called blue-green algae) may produce toxins and taste-and-odor compounds that cause substantial economic and public health concerns, and are of particular interest in lakes, reservoirs, and rivers that are used for drinking-water supply. Blue-green algae is the common name of a group of cyanobacteria commonly found in many lakes and ponds. Paved land, driveways and roads allow surface water to enter your lake easily, carrying with it pollutants and nutrients that feed algae. EGLE staff discover or receive reports from lake associations, and the broader public each year about nuisance algal conditions. A: Blue green algae, or cyanobacteria, can multiply quickly in lakes with high nutrient levels, particularly when the water is warm and the weather is calm. Lake Algae Control & Algae Treatment. Particular problems arise from these cyanobacteria in drinking water supplies. Some types of cyanobacteria can release natural toxins or poisons (called cyanotoxins) into the water, especially when they die and break down. So, to get rid of the blue-green algae, you can shot off your aquarium lights for 2-3 days. In this study, a 73-day laboratory microcosm experiment using suction samplers (Rhizon and syringe) was … If you've got cyanobacteria in your aquarium, you'll need to take quick steps to remove the immediate problem and … Every lake is different and a range of information about the lake needs to be collected when considering a Phoslock treatment. Again, think globally, act locally. Perimeter diking around the dugout combined with an inlet control structure can be used to divert silt-laden or nutrient-rich runoff water away from the dugout. The added H 2 O 2 degraded to water and oxygen within a few days. Greater nutrient loading and warmer weather have led to an increase in the occurrence and magnitude of harmful algae blooms from cyanobacteria in the Great Lakes, throughout North America, Australia, and the world. You may need to download version 2.0 now from the Chrome Web Store. It involves using copper sulfate and hydrogen peroxide, which cause sudden death or lysis of Cyanobacterial cells. Cyanobacteria (blue-green algae) in reservoirs are a primary cause of unfavorable taste and odor in drinking water. No one is surprised by reports that the lake is polluted, Yach Noj says. Ten lakes in the district of Poznan were examined in August 2006 for cyanobacteria and microcysin content. Volume 3, Number 1. pp: 137-143. If you have the means to do so, offer to buy plants and plant them for the farmer down the road who is struggling to make ends meet. If you do come into contact with water that is known to be contaminated with cyanobacteria and/or cyanotoxins, the Centers for Disease Control (CDC) recommends that you rinse off with clean, fresh water as soon as possible. Cyanobacteria is commonly expressed as filamentous, floating or attached. All Rights Reserved. Chemical treatment. Cyanobacteria can interfere with water treatment in various ways, primarily by plugging filters (often large beds of sand and similar media) and by producing cyanotoxins, which have the potential to cause serious illness if consumed. The program targets blue-green algae (cyanobacteria) because these algae pose a health risk to humans, pets, and livestock. The goal is to prevent nutrient inputs into the water. Cyanobacteria identification is possible. Best Management Practices (BMPs), such as grassed buffers and fencing to exclude animals (including livestock) from water, can minimize external phosphorus inputs from soil, fertilizer, and animal manure. The following information is re-printed from Agriculture Canada: A serious problem exists when cyanobacteria grows in ponds and lakes. The new buzz word for water quality is not a new concept at all, but an increasingly important one: watershed management. Cloudflare Ray ID: 5ff1978aed25e68c Think of it as “Phosphorus 101.” Cyanobacteria, also known as blue green algae or red slime algae, behaves like both bacteria and algae. Workshops 1 (Wednesday, 9:00 - noon) The best conservation tools: You and your lake association (Wednesday, 9:00 - noon). Cyanobacteria, also known as blue-green algae, have become a growing concern in the drinking water world. Despite it's common name, blue green algae is not, in fact, an algae, but rather a bacteria called cyanobacteria. that elude conventional drinking water treatment. However, the migration and transformation mechanisms of dissolved carbon (DC) require further study and discussion. We turn to the government to seek information, advice and action which often leaves us feeling frustrated. Cyanobacteria naturally occurs in lakes and have existed on earth for millions of years. Trained specialists visually identify the presence or absence of the bacteria using a microscope. The phytoplankton community of eutrophic shallow lakes is often dominated by filamentous cyanobacteria of the family Oscillatoriaceae. The roots of plants that grow on the islands increase the surface area where friendly bacteria can thrive, so that below the floating island is a massive community of bacteria that break down phosphorous into a protein usable for fish. If a cyanobacteria problem is discovered, properly timed and applied copper treatments may be used to control growth. Some species of cyanobacteria are visible to the naked eye, and may resemble green algae with a bluish tinge. Source of Algae. Another way to prevent getting this page in the future is to use Privacy Pass. Lake Ecology Introduction: Cyanobacteria. Cyanobacteria (blue-green algae) are natural organisms that are present in most lakes. Planktonic blue-green algae can kill fish, and is the most noxious form of aquatic growth that we deal with here in North Texas. The treatment does not deal with the root problem for the growth of cyanobacteria, algae, and plants. Prairie ponds and lakes experience prolific algae growth because the water is nutrient-rich. Cyanobacteria (also called blue-green algae) may produce toxins and taste-and-odor compounds that cause substantial economic and public health concerns, and are of particular interest in lakes, reservoirs, … Freshwater Toxic Algae Data. Most municipal water supplies use specialized treatment to manage blue-green algae. Species of cyanobacteria were the dominants in half of the water samples. For instance, it is important to determine the sources of excess nutrients to your water body; i.e. Chemi-Clean is actually a product that is designed to treat red cyanobacteria in salt-water aquariums, but it is very effecting in getting rid of freshwater cyanobacteria too. Due to different rates of change in total nitrogen (TN) and total phosphorus (TP) concentrations in lakes, increases in TN/TP mass ratios were observed in many China’s freshwater lakes during 2008 to 2017. Do you mow your lawn up to the shoreline? Non-Herbicide Management Options 1. The treatment does not deal with the root problem for the growth of cyanobacteria, algae, and plants. Physical Management Options. Reduce algae in lakes, ponds, rivers and reservoirs using inversion and aeration with bacteria and non-pesticidal chemicals. Many commercial laboratories can identify whether or not cyanobacteria are present in a water sample. How does this relate to your pond or lake? However, as most know Erie is still experiencing problematic blooms. Seek medical treatment right away if you think you or someone you know might have been poisoned by … Microcystins and cylindrospermopsin are highly heat stable (boiling will not destroy them), and they are not easily removed by conventional drinking water treatment methods such as sand filtration, if … 1. 3. Blue-green algae can contaminate drinking water from a surface water source (such as a lake or river) that has a bloom, or from a shallow dug well adjacent to surface water with a bloom. Chemi-Clean Treatment If hydrogen-peroxide is not an option for you or you are not feeling comfortable using it, Chemi-Clean can also help kill blue-green algae.
