Hello , Most of times having a water point at your own house means that it will be used for the household and for productive use for example in/at gardens. From a maintenance point of view this is great it gives a boost to functionality rates. In one of our projects (https://jacana.help/water) we would like to test the presence of pesticides & herbicides in water. Does anybody know how this can be done? Affordable household water treatment can solve a lot of contamination problems already. Although people who just invested in improving their water source often don’t have the capacity or will to invest in water treatment. Because they feel the quality of their water has already improved a lot. Any ideas on removing chemical pollution in a Self-supply setting are also very welcome. This is a list of the most used agro-chemicals in the area: Pesticides Delto 2.5EC - Active ingredient: Deltamethrine 25 G/L Dithane Mancozeb spinosad Indoxacarb Sulphur 80% W Monocrotophos Herbicides Glyphosate Glyphocure Piranah Round up Glyphocure Kolopa and Succeed all containing active ingredients: atrazine, mesotrione, and nicosulfuron Lumax containing tebuthylazin, mesotrione and S-metolachlor Fertilizers Nitrogen, phosphorus, potassium, magnesium, zinc, iron, manganese, copper, boron and molybdenum based fertilizers Kind regards, Rik Haanen rik.haanen@jacana.helpSkype: RikHaanenhttp://jacana.help
