In Cameroon, due to the weaknesses of institutions and inadequate laws, many agro industrial plantations which are in most parts of the country extensively apply fertilizers, pesticides and discharge their untreated waste into nature. These attitudes are consistent for industries, hospitals and individuals. Consequently chemicals are found in ground water. Artisan mining of gold in the South eastern and Eastern parts of Cameroon release substantial quantities of arsenic in to ground water. All these leads to ground water pollution .The ramification of this pollution of ground water is water borne diseases (such as typhoid, cholera and amoebic dysentery which are recurrent in most of the urban cities in Cameroon). This paper investigates why the laws regulating ground water are not enforced and the lacunae of these laws. The paper does so through a reading of records mainly from documentary and internet search. The data thus collected constitutes the sources from which the law is drawn, stated and analyzed in the light of the stated aim of the paper. The results inter alia show that the law that regulate ground water pollution are not well enforced. The said results also highlight the limitation of the available laws regulating ground water pollution in Cameroon. The results are significant as they expose gaps in the current laws regulating ground water pollution and conclude with suggestions on where the law should go.
