    Indicator of bacteria such total coliforms and fecal coliforms are one of the most important environmental factors that effect on water quality. Haraz river is one of three rivers in north of country and it originate from central Alborz. Overall, discharge of unborn sewage, agriculture pesticides, seasonal raining was caused decreasing of quality of the river. Therefore, quality and quantity of the grandwater, surface water and sewage in different zone of this river such Mangol dam is necessary. In this study, total coliforms and fecal coliforms and nematode ovary in 13 stations of Haraz including Sorkhrood, Klodeh, Amol Esar Town, Helomsar, Mangol dam, Karesang, Jalav bridge, Norroud, Tehran 115, Larijan, Abeask, Lasem, Lar (pleur) were surveyed. ECC Chrome agar was used for counting and isolation of coliforms groups and nematode ovary counting was done as formal – ether sedimentation method. The results showed that maximum and minimum of total coliforms in surface water was observed in Sorkhrood (9.4 CFU/100ml) and Lasem (4.2CFU/100ml) and also maximum and minimum of fecal coliforms in Sorkhrood (3/2 CFU / ml) and Lasem (1/1CFU/100ml) respectively. Maximum and minimum of these bacteria in ground water were Abeask (4 CFU /100ml) and Helomsar (9/1 CFU/100ml) (for total coliforms) and Abeask (7/1 CFU/100ml) and Helomsar, Klodeh and Larijan (2/1 CFU/100ml) (for fecal coliforms) respectively. Maximum and minimum of total and fecal coliforms in sewage were Norroud (1/3 CFU/100ml) and Amole Esar Town (2/2 CFU/100ml) (for total coliforms) and Norroud (6/1 CFU/100ml) and Amole Esar Town and Tehran 115 (2/1 CFU/100ml) (for fecal coliforms) respectively. Ovary of Nematode in sewage was 30 and 124 in Norroud and Amole Esar Town respectively. The conclusion of this study was showed that quality of Haraz is low level and not proper for drinking and swimming. Iranian Fisheries Science Research Institute Published

    This study was conducted to determine water quality of surface water (7 stations), ground water (5 stations) and wastewater (4 stations) at Haraz River during instruction of Mangol Dam in 2009-2010. This study is to follow physico-chemical fluctuation of waters and compared the data obtained with previous studies and standard levels. Results of current study showed that annual mean with standard error of temperature, DO, BOD5, COD, HCO3-, CO32-, TA, Ca2+, Mg2+, TH, TSS, TDS, Cl-, PO43-, NH4+, NO2- and NO3- were observed 12.7 (±0.61) centigrade, 10.13 (±0.12), 2.1 (±0.1), 7.71 (±0.99), 28.1 (±6.1), 14.34 (±1.64), 36.30 (±2.33), 64.66 (±2.34), 28.84 (±1.52), 271.62 (±8.41), 0.37 (±0.03), 0.30 (±0.02), 28.02 (±1.96), 0.06 (±0.01), 0.010 (±0.001) and 0.94 (±0.03) mg/l, pH was 8.00 (±0.02) and EC 0.50 (±0.02) ms/cm in surface water. The annual mean with standard error of temperature, HCO3-, CO32-, TA, Ca2+, Mg2+, TH, TSS, TDS, Cl-, PO43-, NH4+, NO2- and NO3- were observed 21.62 (±1.03) centigrade, 54 (±5), 11 (±5), 57 (±5), 208.6 (±42.5), 109 (±23), 1088 (±165), 0.065 (±0.017), 0.97 (±0.11), 317.8 (±76.2), 0.25 (±0.06), 0.06 (±0.01), 0.0007 (±0.0001) and 0.78 (±0.05) mg/l, pH was 7.37 (±0.07) and EC 1.98 (±0.23) ms/cm in underground water. In addition, the annual mean with standard error of temperatute, DO, BOD5, COD, TSS, TDS, and NO3- were observed 12.7 (±0.61) centigrade, 13.59 (±0.87), 9.80 (±0.12), 2.22 (±0.18), 7.54 (±1.02), 0.50 (±0.03), 0.320 (±0.008) and 0.990 (±0.016) mg/l, pH was 7.95 (±0.02) and EC 0.64 (±0.01) ms/cm in wastewater. Quality of surface water of Haraz River and its branches were almost contained suitable for usual applications, but sometimes the quality of surface water based on BOD5 need to more attention for man uses (such as supply of drinking water). In addition, the quality of surface water was relatively suitable for aquatic based on the aquatic standard levels. Results also showed that water quality index (WQI) was declined from upstream to downstream and some parameters were not in standard ranges. The quality of surface water classified in group II at all stations based on water classification rules which it shows serious water quality changes due to environmental destroyed and domestic, agriculture sewage pollutions. Groundwater were affected by different springs at middle and downstream which they caused change physico-chemical characteristics and water quality. Wastewater was classified from good to moderate based on BOD5. The quality of wastewater was declined at donw stream with decreasing DO and pH and increasing BOD5 and pollutants.

    Arid countries throughout the world are heavily reliant on seawater desalination for their supply of drinking and municipal water. The desalination industry is large and rapidly growing, approaching more than 20,000 plants operating or contracted in greater than 150 countries worldwide and capacity projected to grow at a rate of 12% per year for the next several decades (http://www.desaldata.com; 2016). Desalination plants are broadly distributed worldwide, with a large and growing capacity in what will be referred to as the “Gulf” region throughout this manual. Here the Gulf refers to the shallow body of water bounded in the southwest by the Arabian Peninsula and Iran to the northeast. The Gulf is linked with the Arabian Sea by the Strait of Hormuz and the Gulf of Oman to the east and extends to the Shatt al-Arab river delta at its western end. One of the operational challenges facing the industry is also expanding globally – the phenomena termed harmful algal blooms or HABs. Blooms are cell proliferations caused by the growth and accumulation of individual algal species; they occur in virtually all bodies of water. The algae, which can be either microscopic or macroscopic (e.g., seaweeds) are the base of the marine food web, and produce roughly half of the oxygen we breathe. Most of the thousands of species of algae are beneficial to humans and the environment, but there are a small number (several hundred) that cause HABs. This number is vague because the harm caused by HABs is diverse and affects many different sectors of society (see Chapter 1). HABs are generally considered in two groups. One contains the species that produce potent toxins (Chapter 2) that can cause a wide range of impacts to marine resources, including mass mortalities of fish, shellfish, seabirds, marine mammals, and various other organisms, as well as illness and death in humans and other consumers of fish or shellfish that have accumulated the algal toxins during feeding. The second category is represented by species that produce dense blooms - often termed high biomass blooms because of the large number of cells. Cells can reach concentrations sufficient to make the water appear red (hence the common term “red tide”), though brown, green and golden blooms are also observed, while many blooms are not visible. In this manual, we define toxic algae as those that produce potent toxins (poisonous substances produced within living cells or organisms), e.g., saxitoxin. These can cause illness or mortality in humans as well as marine life through either direct exposure to the toxin or ingestion of bioaccumulated toxin in higher trophic levels e.g. shellfish. Non-toxic HABs can cause damage to ecosystems and commercial facilities such as desalination plants, sometimes because of the biomass of the accumulated algae, and in other cases due to the release of compounds that are not toxins (e.g., reactive oxygen species, mucilage) but that can still be lethal to marine animals or cause disruptions of other types. Both toxic and non-toxic HABs represent potential threats to seawater desalination facilities. Although toxins are typically removed very well by reverse osmosis and thermal desalination processes (see Chapter 10), algal toxins represent a potential health risk if they are present in sufficiently high concentrations in the seawater and if they break through the desalination process. It is therefore important for operators to be aware when toxic blooms are near their plants so they can ensure that the removal has indeed occurred (Chapter 3). High biomass blooms pose a different type of threat, as the resulting particulate and dissolved organic material can accelerate clogging of media filters or contribute to (bio)fouling of pretreatment and RO membranes which may lead to a loss of production. Impacts of HABs on desalination facilities are thus a significant and growing problem, made worse by the lack of knowledge of this phenomena among plant operators, managers, engineers, and others involved in the industry, including regulatory agencies. Recognizing this problem, the Middle East Desalination Research Center (MEDRC) and the UNESCO Intergovernmental Oceanographic Commission (IOC) organized a conference in 2012 in Muscat, Oman, to bring HAB researchers and desalination professionals together to exchange knowledge and discuss the scale of the problem and strategies for addressing it. One of the recommendations of that meeting was that a “guidance manual” be prepared to provide information to desalination plant operators and others in the industry about HABs, their impacts, and the strategies that could be used to mitigate those impacts. With support from the US Agency for International Development (USAID) and the IOC Intergovernmental Panel for Harmful Algal Blooms (IPHAB), an editorial team was assembled and potential authors contacted. For the first time, HAB scientists worked closely with desalination professionals to write chapters that were scientifically rigorous yet practical in nature – all focused on HABs and desalination. During the planning of this manual, it became clear from an informal survey of the desalination industry that generally, HAB problems are far more significant for seawater reverse osmosis (SWRO) plants than for those that use thermal desalination. Both types of processes are very effective in removing HAB toxins (Chapter 10), but the SWRO plants are far more susceptible to clogging of pretreatment granular media filters and fouling of membranes by algal organic matter and particulate biomass. Accordingly, the focus of this book is on SWRO, with only occasional reference to thermal processes. Likewise, emphasis has been placed on seawater HABs, with reference to estuarine and brackish-water HABs only when practices from those types of waters can be informative or illustrative. A brief synopsis of the book follows. Chapter 1 provides a broad overview of HAB phenomena, including their impacts, the spatial and temporal nature of their blooms, common causative species, trends in occurrence, and general aspects of bloom dynamics in coastal waters. Chapter 2 describes the metabolites of HAB cells, including toxins, taste and odor compounds. Methods for analyses are presented there, supplemented by detailed methodological descriptions of rapid toxin screening methods in Appendix 2. As discussed in Chapters 8 and 10, thermal and SWRO operations are highly effective in the removal of HAB toxins, but plant personnel should have the capability to screen for these toxins in raw and treated water to ensure that this removal has been effective. This would be critical, for example, if the public or the press were aware of a toxic HAB in the vicinity of a desalination plant intake and asked for proof that their drinking water is safe. Currently, most desalination plants do not collect data on seawater outside their plants, so they are generally unaware of the presence (now or anticipated) of a potentially disruptive HAB. Chapter 3 provides practical information on the approaches to implementing an observing system for HABs, describing sampling methods and measurement options that can be tailored to available resources and the nature of the HAB threat in a given area. Appendix 4 provides more details on methods used to count and identify HAB cells during this process. All are based on direct water sampling, but it is also possible to observe HABs from space – particularly the high biomass events. Chapter 4 describes how satellite remote sensing can be used to detect booms. The common sources of imagery (free over the Internet) are presented, as well as descriptions of the software (also free) that can be used to analyze the satellite data. It is relatively easy and highly informative for plant personnel to use this approach to better understand what is in the seawater outside their plants. The cover of this guide provides a graphic example of the incredible scale and resolution of this observational approach. Chapter 5 discusses typical water quality parameters that are measured online or in feedwater samples at desalination plants that could be used to detect blooms at the intake or evaluate process efficiency in removing algal particulates and organics. Emerging parameters that also show promise are examined to provide a resource for plant personnel. Chapter 6 looks at desalination seawater intakes that are the first point of control in minimizing the ingress of algae into the plant. A brief overview of siting considerations that may ultimately drive the location of an intake is also provided. One question asked frequently of HAB scientists is whether the blooms can be controlled or suppressed in a manner analogous to the treatment of insects or other agricultural pests on land. This has proven to be an exceedingly difficult challenge for the HAB scientific and management community, given the dynamic nature of HABs in coastal waters, their large spatial extent, and concerns about the environmental impacts of bloom control methods. Chapter 7 presents a summary of the approaches to bloom prevention and control that have been developed, and discusses whether these are feasible or realistic in the context of an individual desalination plant. Chapter 8 describes management strategies for HABs and risk assessment, including Hazard Analysis Critical Control Point (HACCP) and Alert Level Framework procedures. Once a HAB is detected, a wide range of approaches can be used to address the problems posed by the dissolved toxins associated with those blooms. Chapter 9 presents many of these pretreatment strategies and discusses their use in removing algal organic matter and particulates to prevent filter clogging and membrane fouling. This is necessary to maintain effective plant operation and avoid serious operational challenges for the reverse osmosis step. The chapter covers common pretreatments such as chlorination/dechlorination, coagulation, dissolved air flotation, granular media filtration, ultrafiltration, and cartridge filtration, in addition to discussing issues experienced due to the inefficiencies of each pretreatment on reverse osmosis. Chapter 10 then addresses the important issue of HAB toxin removal during pretreatment and desalination, and describes laboratory and pilot-scale studies that address that issue. Finally, Chapter 11 provides a series of case studies describing individual HAB events at desalination plants throughout the world, detailing the types of impacts and the strategies that were used to combat them. These studies should be of great interest to other operators as they encounter similar challenges. The manual concludes with a series of appendices that provide images and short descriptions of common HAB species (Appendix 1), rapid screening methods for HAB toxins (Appendix 2), methods to measure transparent exopolymer particles (TEP) and their precursors (Appendix 3), methods to enumerate algal cells (Appendix 4), and reverse osmosis autopsy and cleaning methods (Appendix 5).

    The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango trees underlines long human occupation of the more productive areas. Published

    Indicator of bacteria such total coliforms and fecal coliforms are one of the most important environmental factors that effect on water quality. Haraz river is one of three rivers in north of country and it originate from central Alborz. Overall, discharge of unborn sewage, agriculture pesticides, seasonal raining was caused decreasing of quality of the river. Therefore, quality and quantity of the grandwater, surface water and sewage in different zone of this river such Mangol dam is necessary. In this study, total coliforms and fecal coliforms and nematode ovary in 13 stations of Haraz including Sorkhrood, Klodeh, Amol Esar Town, Helomsar, Mangol dam, Karesang, Jalav bridge, Norroud, Tehran 115, Larijan, Abeask, Lasem, Lar (pleur) were surveyed. ECC Chrome agar was used for counting and isolation of coliforms groups and nematode ovary counting was done as formal – ether sedimentation method. The results showed that maximum and minimum of total coliforms in surface water was observed in Sorkhrood (9.4 CFU/100ml) and Lasem (4.2CFU/100ml) and also maximum and minimum of fecal coliforms in Sorkhrood (3/2 CFU / ml) and Lasem (1/1CFU/100ml) respectively. Maximum and minimum of these bacteria in ground water were Abeask (4 CFU /100ml) and Helomsar (9/1 CFU/100ml) (for total coliforms) and Abeask (7/1 CFU/100ml) and Helomsar, Klodeh and Larijan (2/1 CFU/100ml) (for fecal coliforms) respectively. Maximum and minimum of total and fecal coliforms in sewage were Norroud (1/3 CFU/100ml) and Amole Esar Town (2/2 CFU/100ml) (for total coliforms) and Norroud (6/1 CFU/100ml) and Amole Esar Town and Tehran 115 (2/1 CFU/100ml) (for fecal coliforms) respectively. Ovary of Nematode in sewage was 30 and 124 in Norroud and Amole Esar Town respectively. The conclusion of this study was showed that quality of Haraz is low level and not proper for drinking and swimming. Iranian Fisheries Science Research Institute Published

    This study was conducted to determine water quality of surface water (7 stations), ground water (5 stations) and wastewater (4 stations) at Haraz River during instruction of Mangol Dam in 2009-2010. This study is to follow physico-chemical fluctuation of waters and compared the data obtained with previous studies and standard levels. Results of current study showed that annual mean with standard error of temperature, DO, BOD5, COD, HCO3-, CO32-, TA, Ca2+, Mg2+, TH, TSS, TDS, Cl-, PO43-, NH4+, NO2- and NO3- were observed 12.7 (±0.61) centigrade, 10.13 (±0.12), 2.1 (±0.1), 7.71 (±0.99), 28.1 (±6.1), 14.34 (±1.64), 36.30 (±2.33), 64.66 (±2.34), 28.84 (±1.52), 271.62 (±8.41), 0.37 (±0.03), 0.30 (±0.02), 28.02 (±1.96), 0.06 (±0.01), 0.010 (±0.001) and 0.94 (±0.03) mg/l, pH was 8.00 (±0.02) and EC 0.50 (±0.02) ms/cm in surface water. The annual mean with standard error of temperature, HCO3-, CO32-, TA, Ca2+, Mg2+, TH, TSS, TDS, Cl-, PO43-, NH4+, NO2- and NO3- were observed 21.62 (±1.03) centigrade, 54 (±5), 11 (±5), 57 (±5), 208.6 (±42.5), 109 (±23), 1088 (±165), 0.065 (±0.017), 0.97 (±0.11), 317.8 (±76.2), 0.25 (±0.06), 0.06 (±0.01), 0.0007 (±0.0001) and 0.78 (±0.05) mg/l, pH was 7.37 (±0.07) and EC 1.98 (±0.23) ms/cm in underground water. In addition, the annual mean with standard error of temperatute, DO, BOD5, COD, TSS, TDS, and NO3- were observed 12.7 (±0.61) centigrade, 13.59 (±0.87), 9.80 (±0.12), 2.22 (±0.18), 7.54 (±1.02), 0.50 (±0.03), 0.320 (±0.008) and 0.990 (±0.016) mg/l, pH was 7.95 (±0.02) and EC 0.64 (±0.01) ms/cm in wastewater. Quality of surface water of Haraz River and its branches were almost contained suitable for usual applications, but sometimes the quality of surface water based on BOD5 need to more attention for man uses (such as supply of drinking water). In addition, the quality of surface water was relatively suitable for aquatic based on the aquatic standard levels. Results also showed that water quality index (WQI) was declined from upstream to downstream and some parameters were not in standard ranges. The quality of surface water classified in group II at all stations based on water classification rules which it shows serious water quality changes due to environmental destroyed and domestic, agriculture sewage pollutions. Groundwater were affected by different springs at middle and downstream which they caused change physico-chemical characteristics and water quality. Wastewater was classified from good to moderate based on BOD5. The quality of wastewater was declined at donw stream with decreasing DO and pH and increasing BOD5 and pollutants.

    Arid countries throughout the world are heavily reliant on seawater desalination for their supply of drinking and municipal water. The desalination industry is large and rapidly growing, approaching more than 20,000 plants operating or contracted in greater than 150 countries worldwide and capacity projected to grow at a rate of 12% per year for the next several decades (http://www.desaldata.com; 2016). Desalination plants are broadly distributed worldwide, with a large and growing capacity in what will be referred to as the “Gulf” region throughout this manual. Here the Gulf refers to the shallow body of water bounded in the southwest by the Arabian Peninsula and Iran to the northeast. The Gulf is linked with the Arabian Sea by the Strait of Hormuz and the Gulf of Oman to the east and extends to the Shatt al-Arab river delta at its western end. One of the operational challenges facing the industry is also expanding globally – the phenomena termed harmful algal blooms or HABs. Blooms are cell proliferations caused by the growth and accumulation of individual algal species; they occur in virtually all bodies of water. The algae, which can be either microscopic or macroscopic (e.g., seaweeds) are the base of the marine food web, and produce roughly half of the oxygen we breathe. Most of the thousands of species of algae are beneficial to humans and the environment, but there are a small number (several hundred) that cause HABs. This number is vague because the harm caused by HABs is diverse and affects many different sectors of society (see Chapter 1). HABs are generally considered in two groups. One contains the species that produce potent toxins (Chapter 2) that can cause a wide range of impacts to marine resources, including mass mortalities of fish, shellfish, seabirds, marine mammals, and various other organisms, as well as illness and death in humans and other consumers of fish or shellfish that have accumulated the algal toxins during feeding. The second category is represented by species that produce dense blooms - often termed high biomass blooms because of the large number of cells. Cells can reach concentrations sufficient to make the water appear red (hence the common term “red tide”), though brown, green and golden blooms are also observed, while many blooms are not visible. In this manual, we define toxic algae as those that produce potent toxins (poisonous substances produced within living cells or organisms), e.g., saxitoxin. These can cause illness or mortality in humans as well as marine life through either direct exposure to the toxin or ingestion of bioaccumulated toxin in higher trophic levels e.g. shellfish. Non-toxic HABs can cause damage to ecosystems and commercial facilities such as desalination plants, sometimes because of the biomass of the accumulated algae, and in other cases due to the release of compounds that are not toxins (e.g., reactive oxygen species, mucilage) but that can still be lethal to marine animals or cause disruptions of other types. Both toxic and non-toxic HABs represent potential threats to seawater desalination facilities. Although toxins are typically removed very well by reverse osmosis and thermal desalination processes (see Chapter 10), algal toxins represent a potential health risk if they are present in sufficiently high concentrations in the seawater and if they break through the desalination process. It is therefore important for operators to be aware when toxic blooms are near their plants so they can ensure that the removal has indeed occurred (Chapter 3). High biomass blooms pose a different type of threat, as the resulting particulate and dissolved organic material can accelerate clogging of media filters or contribute to (bio)fouling of pretreatment and RO membranes which may lead to a loss of production. Impacts of HABs on desalination facilities are thus a significant and growing problem, made worse by the lack of knowledge of this phenomena among plant operators, managers, engineers, and others involved in the industry, including regulatory agencies. Recognizing this problem, the Middle East Desalination Research Center (MEDRC) and the UNESCO Intergovernmental Oceanographic Commission (IOC) organized a conference in 2012 in Muscat, Oman, to bring HAB researchers and desalination professionals together to exchange knowledge and discuss the scale of the problem and strategies for addressing it. One of the recommendations of that meeting was that a “guidance manual” be prepared to provide information to desalination plant operators and others in the industry about HABs, their impacts, and the strategies that could be used to mitigate those impacts. With support from the US Agency for International Development (USAID) and the IOC Intergovernmental Panel for Harmful Algal Blooms (IPHAB), an editorial team was assembled and potential authors contacted. For the first time, HAB scientists worked closely with desalination professionals to write chapters that were scientifically rigorous yet practical in nature – all focused on HABs and desalination. During the planning of this manual, it became clear from an informal survey of the desalination industry that generally, HAB problems are far more significant for seawater reverse osmosis (SWRO) plants than for those that use thermal desalination. Both types of processes are very effective in removing HAB toxins (Chapter 10), but the SWRO plants are far more susceptible to clogging of pretreatment granular media filters and fouling of membranes by algal organic matter and particulate biomass. Accordingly, the focus of this book is on SWRO, with only occasional reference to thermal processes. Likewise, emphasis has been placed on seawater HABs, with reference to estuarine and brackish-water HABs only when practices from those types of waters can be informative or illustrative. A brief synopsis of the book follows. Chapter 1 provides a broad overview of HAB phenomena, including their impacts, the spatial and temporal nature of their blooms, common causative species, trends in occurrence, and general aspects of bloom dynamics in coastal waters. Chapter 2 describes the metabolites of HAB cells, including toxins, taste and odor compounds. Methods for analyses are presented there, supplemented by detailed methodological descriptions of rapid toxin screening methods in Appendix 2. As discussed in Chapters 8 and 10, thermal and SWRO operations are highly effective in the removal of HAB toxins, but plant personnel should have the capability to screen for these toxins in raw and treated water to ensure that this removal has been effective. This would be critical, for example, if the public or the press were aware of a toxic HAB in the vicinity of a desalination plant intake and asked for proof that their drinking water is safe. Currently, most desalination plants do not collect data on seawater outside their plants, so they are generally unaware of the presence (now or anticipated) of a potentially disruptive HAB. Chapter 3 provides practical information on the approaches to implementing an observing system for HABs, describing sampling methods and measurement options that can be tailored to available resources and the nature of the HAB threat in a given area. Appendix 4 provides more details on methods used to count and identify HAB cells during this process. All are based on direct water sampling, but it is also possible to observe HABs from space – particularly the high biomass events. Chapter 4 describes how satellite remote sensing can be used to detect booms. The common sources of imagery (free over the Internet) are presented, as well as descriptions of the software (also free) that can be used to analyze the satellite data. It is relatively easy and highly informative for plant personnel to use this approach to better understand what is in the seawater outside their plants. The cover of this guide provides a graphic example of the incredible scale and resolution of this observational approach. Chapter 5 discusses typical water quality parameters that are measured online or in feedwater samples at desalination plants that could be used to detect blooms at the intake or evaluate process efficiency in removing algal particulates and organics. Emerging parameters that also show promise are examined to provide a resource for plant personnel. Chapter 6 looks at desalination seawater intakes that are the first point of control in minimizing the ingress of algae into the plant. A brief overview of siting considerations that may ultimately drive the location of an intake is also provided. One question asked frequently of HAB scientists is whether the blooms can be controlled or suppressed in a manner analogous to the treatment of insects or other agricultural pests on land. This has proven to be an exceedingly difficult challenge for the HAB scientific and management community, given the dynamic nature of HABs in coastal waters, their large spatial extent, and concerns about the environmental impacts of bloom control methods. Chapter 7 presents a summary of the approaches to bloom prevention and control that have been developed, and discusses whether these are feasible or realistic in the context of an individual desalination plant. Chapter 8 describes management strategies for HABs and risk assessment, including Hazard Analysis Critical Control Point (HACCP) and Alert Level Framework procedures. Once a HAB is detected, a wide range of approaches can be used to address the problems posed by the dissolved toxins associated with those blooms. Chapter 9 presents many of these pretreatment strategies and discusses their use in removing algal organic matter and particulates to prevent filter clogging and membrane fouling. This is necessary to maintain effective plant operation and avoid serious operational challenges for the reverse osmosis step. The chapter covers common pretreatments such as chlorination/dechlorination, coagulation, dissolved air flotation, granular media filtration, ultrafiltration, and cartridge filtration, in addition to discussing issues experienced due to the inefficiencies of each pretreatment on reverse osmosis. Chapter 10 then addresses the important issue of HAB toxin removal during pretreatment and desalination, and describes laboratory and pilot-scale studies that address that issue. Finally, Chapter 11 provides a series of case studies describing individual HAB events at desalination plants throughout the world, detailing the types of impacts and the strategies that were used to combat them. These studies should be of great interest to other operators as they encounter similar challenges. The manual concludes with a series of appendices that provide images and short descriptions of common HAB species (Appendix 1), rapid screening methods for HAB toxins (Appendix 2), methods to measure transparent exopolymer particles (TEP) and their precursors (Appendix 3), methods to enumerate algal cells (Appendix 4), and reverse osmosis autopsy and cleaning methods (Appendix 5).

    The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango trees underlines long human occupation of the more productive areas. Published
