Dear Brent Ryan There are some examples of river cleaning project- In India cleaning the Ganga and the Yamuna, in Seoul, the Han River’s millions of batteries are thrown in the rivers. Raw sewage added to water flows like canals and rivers , You need to find the source that is polluting it and stop further pollution so now the river will be come naturally and logically clean free from chemicals .Industry contaminates practically unchecked .farmers using agro chemicals (fertilizers ,herbicides & pesticides)then deforest and the rains washing the topsoil’s impregnated with contaminants into the rivers. Thousands of women that do the washing in rivers using harmful detergents. Farmers dump acidic coffee husk into the waters which kills millions of fish ,on the coasts oil spills that contaminate coastal waters, The sample collection process should be coordinated with the laboratory so that analysts know how many samples will be arriving, the approximate time of their arrival and the analyses that are to be carried out, and can thus have appropriate quantities of reagent chemicals prepared. Personnel who will collect water, biota or sediment samples must be fully trained in both sampling techniques and field test procedures. They should also be aware of the objectives of the monitoring programme since these will have some influence on the sampling procedures. For sampling √ Sample bottles, preservatives, labels and marker pens √ Sample storage/transit containers and ice packs √ Filtering apparatus (if required) √ Samplers/sampling equipment √ Rubber boots, waders, etc. √ Standard operating procedures for sampling √ Spares of all above items if possible and when appropriate For documentation √ Pens/wax crayons √ Sample labels √ Field notebook √ Report forms For on-site testing √ List of analyses to be performed on site √ Check stocks of consumables (including distilled water, pH buffers, standards and blanks); replenish and refresh as appropriate √ Check and calibrate meters (pH, conductivity, dissolved oxygen, turbidity, thermometers) √ Other testing equipment according to local practice √ Standard operating procedures and equipment manuals √ Spares (e.g. batteries) Safety √ First-aid kit √ Waders, gloves, etc. √ Fire extinguisher (if appropriate) Transport √ Does assigned vehicle have sufficient capacity for personnel, supplies and equipment? √ Is vehicle road-worthy? Check battery, lubrication, coolant, windshield washer √ Is there sufficient fuel for the trip, either in the tank, in fuel cans, or available en route? √ Is the spare tyre inflated, is there a jack, wheel wrench and tool kit? Double-check √ When was equipment last calibrated? √ Itinerary against travel details on inventory √ Accessories for equipment and meters (including cables, chargers and spare batteries) and consumables. Only if samples can be taken consistently from the same locations, can changes in the concentration of water quality variables with time be interpreted with confidence. Sample containers Containers for the transportation of samples are best provided by the laboratory. This ensures that large enough samples are obtained for the planned analyses and that sample bottles have been properly prepared, including the addition of stabilizing preservatives when necessary. SECONDARY POLUTION changes in water temperature enhances harmful algae,(remember the red tide) and kills many fish who are critical to temperature ,when sea water enters lagoons here in Mexico many fish die ,due to sudden temperature changes .also warm water releases carbon gasses cold water absorbs them SOLUTIONS wetlands like swamps have always been Natures natural filters for natural water flows, aquatic plants clean the water ,the anchored plants as well as the floating ones .we should redesign wetland flora with in natural water systems to help contra contamination. Stop sewage systems that connect to natural water flows, forbid and police the dumping of rubbish on waters edges, the best way is through the educational systems, starting at kiddy schools and rising in intensity with progression. Cleaning project for revers According to pollutants The plant to be installed in river side and the parts of the river water to be cleaned by primary clarifier secondary clarifier, membranes biological treatment , bacteria treatment etc to be installed.
