50 | LEA/Limited Environmental Impact Assessment (For Category - II schemes) (Fills up automatically) | |||||||
51 | - | - | Length of pumping main exceeding 2km, involves considerable trenching for the pipes, burial, deployment of heavy equipments etc. This can result in dust emanation,noise generation,Hazards to the health and safety of workmen,affect vehicular traffic | - | - | - | - | |
52 | - | - | - | Source is located in area having inadequate drainage, this can result in infiltration and percolation of drainage water into the source thereby polluting the source.It can also become breeding ground for communicable diseases like cholera and typhoid | - | - | - | |
53 | - | Source well situated in water logged area,percolation of polluted water is anticipated.The water stagnent area may also become a breeding ground for communcable diseases like cholera and typhoid | - | Trees are to be cut as part of clearing the site for works,it will affect the natural vegetation of the area and may have an impact on the biodiversity of the area | Source water contains iron above permissibile limit.Presence of iron in water imparts colour and taste to water.Iron concentrations of 1–3 mg/litre can be acceptable for people drinking anaerobic well water(Ref.WHO). | - | - | |
54 | - | Water is acidic in nature,The normal range for pH in surface water systems is 6.5 to 8.5, and the pH range for groundwater systems is between 6 to 8.5.pH values lesser than 4 can cause skin and eye irritations.A pH value below 2.5 will cause irreversible damage to skin and organ linings | - | Coliforms present in water.Fecal coliforms are the group of the total coliforms that are considered to be present specifically in the gut and feces of warm-blooded animals.It indicates bacteriological contamination of water | - | - | - | |
55 | Environment Management Plan (Fills up automatically) | |||||||
56 | - | - | Length of pumping main exceeding 2km, Trench width shall not exceed 100mm than the pipe diameter,Warning tapes,boards to be in place,shoring,scaffoldings for depth above 1.5m, water shall be sprinkled to avoid dust flying.Work to be scheduled to avoid peak hours and to avoid public nuissance. | - | - | - | - | |
57 | - | - | - | Source is located in area having inadequate drainage, proper drainage facilities shall be provided including diversion of drainage if required | - | - | - | |
58 | - | Source well situated in water logged area,percolation of polluted water is anticipated,provision for draining out the stagnent water shall be made by suitable means depending on field conditions-construction of drains or by land filling | - | Trees are to be cut as part of clearing the site for works,it will affect the natural vegetation of the area.Sanction for cutting trees has to be obtained from Kerala forest and wild life department. For a single tree that is to be cut 3 tree saplings shall be planted and taken care of. | Source water contains iron above permissibile limit.Water treatment filters shall be installed which shall be working on aeration/chlorination/chemical oxidation using pottasium permanganate and settling/filtration combination or adsorption using green sand media/natural media or ion exchange resins | - | - | |
59 | - | Water is acidic in nature,Acid neutralising filters,chemical feed systems injecting a neutralising solution such as calcium carbonate or chlorine dosing system can be used for pH below 6.5 | - | Fecal coliforms present For chemical disinfection of water the following disinfectants can be used:Chlorine (Cl2),Chlorine dioxide (ClO2),Hypo chlorite (OCl-),Ozone (O3)Halogens: bromine (Br2),iodene (I)Bromine chloride (BrCl)Metals: copper (Cu2+), silver (Ag+),potassium permanganate (KMnO4),Alcohols,For physical disinfection:- Ultraviolet light (UV),Electronic radiation,Gamma rays,Sounds,Heat can be used. | - | - | - | |
