Assam Tribune report---Arsenic and fluoride contamination of ground water in Assam

Source of Article :http://www.assamtribune.com/scripts/detailsnew.asp?id=jan2916/at056


Groundwater contamination cases rising in State
Ajit Patowary
 GUWAHATI, Jan 28 - Cases of contamination of groundwater in the State are swelling up everyday, making groundwater unsafe for consumption. According to the official data, the number of the State’s districts which have got their groundwater contaminated by fluoride and arsenic has shot up to 22 and 21 respectively from 19 and 20 respectively in 2014-’15.

According to the data available with this newspaper, in 2014-’15, the arsenic affected districts of the State included Baksa, Barpeta, Bongaigaon, Cachar, Darrang, Dhemaji, Dhubri, Goalpara, Hailakandi, Jorhat, Kamrup, Karimganj, Kokrajhar, Lakhimpur, Morigaon, Nagaon, Nalbari, Sivasagar and Sonitpur.
This year, Tinsukia has also been found to be affected by arsenic, raising the number of affected districts to 21, said the sources.
Till 2013-’14, nine districts – Barpeta, Dhubri, Goalpara, Golaghat, Jorhat, Kamrup, Karbi Anglong, Karimganj and Nagaon – were found to be affected by fluoride.
But in 2014-’15, with the inclusion of Baksa, Cachar, Chirang, Darrang, Dibrugarh, Morigaon, Nalbari, Sivasagar, Sonitpur and Udalguri, the number of affected districts rose to 19.
In 2015-’16, with the inclusion of Bongaigaon, Lakhimpur and Tinsukia, the number of fluoride-affected districts have shot up to 22, sources said.
According to experts here, the trend of rise in the number of fluoride and arsenic affected districts should be studied, together with the impact of such contamination of groundwater, which is used by the people of many areas in these districts for the purpose of drinking as well as domestic use, on human and animal health.
Except in the two districts of Karbi Anglong and Nagaon, no comprehensive health impact studies of groundwater contamination in the rest of the districts has so far been known to have been conducted, said the experts. The origin of fluoride so far is known to be geogenic.

The State’s Department of Mining and Mineral may undertake such studies, involving also the Public Health Engineering Department (PHED), Council of Scientific and Industrial Research (CSIR), Central Ground Water Board (CGWB) and the North Eastern Regional Institute of Water and Land Management (NERIWALM) in this regard, said the experts.

Low cost Arsenic Fluoride Filter

LOW COST ARSENIC & FLUORIDE FILTER
INTRODUCTION:
What are the possible health effects of arsenic in drinking water?
According to a 1999 study by the National Academy of Sciences, arsenic in drinking water causes bladder, lung and skin cancer, and may cause kidney and liver cancer. The study also found that arsenic harms the central and peripheral nervous systems, as well as heart and blood vessels, and causes serious skin problems. It also may cause birth defects and reproductive problems.
WHO Standards for Arsenic:
The World Health Organizations (WHOs) current provisional guideline for arsenic in drinking water is 10 ppb. In India, states like Uttar Pradesh, Bihar, Jharkhnad, West Bengal, Assam, Manipur, mainly in Ganga-Meghna-Brahmaputra (GMB) plain covering an area of about 569749 sq km with a population of over 500 million have reported serious illnesses due to presence of arsenic.

                                   

.
TECHNOLOGIES AVAILABLE FOR ARSENIC FLUORIDE  REMOVAL:
Activated Alumina and Reverse Osmosis (RO) are the only two methods for removing fluoride and arsenic.

About Activated Alumina

 

Activated alumina is a filter media made by treating aluminum ore so that it becomes porous and highly adsorptive. Activated alumina will remove a variety of contaminants including excessive fluoride, arsenic and selenium. The medium requires periodic cleaning with an appropriate regenerate such as alum or acid in order to remain effective. During the process about 5–10% of the alumina is lost and the capacity of the regenerated medium is reduced by 30–40%. The activated alumina needs replacement after 3–4 regenerations

 


FLOW CHART :
Pond/well---Pump---Iron Filter----Activated Alumina Filters---Activated Carbon Filter----UV Tube disinfection----Collection Tank----Supply by 20 Ltr JAR

DESCRIPTION OF PARTS OF THE SYSTEM :

The Iron filter with iron removal media is very high efficiency in Iron, turbidity and bacterial removal.


The Activated Alumina Filter removes both Arsenic and Fluoride. This is a WHO approved conventional method applied all over the world..

The Activated Carbon filter removes residual colour ,odour and Iron. Also it removes the bad effects of activated alumina.

UV Tube disinfects the water before supply.

Source of Water : Pond, Well
To provide 10 liters per capita per day (LPCD) of safe drinking water for drinking and cooking purposes in areas affected by fluoride, arsenic, heavy metals and pesticides. 
Quantity: 3000 Liter per day (For 300 persons @10 liter per person per day ).

Project Cost: .Equipment cost will be around Rs. Three Lac only. Building and other infrastructure cost extra.
To design a system we need

1. The total quantity of water to be treated


2. A water test is recommended.




FOR A SINGLE HOUSE: 1000LPH FRP Vessel Filter with Arsenic fluoride media .Cost:Rs.40,000/=
