From the declaration made by the African Mayors in Senegal; the Mayors and Municipal Health Officers of the Americas in Columbia; the City Executives of Cities and Local Governments of the World in Spain and in the context of the Millennium Development Goals MDG 1&7; there is a need for increased food production in urban and peri-urban areas UPA in the world. Sub-Saharan Africa faces more development challenges than any other major region of the world with most of the people living in slums, without access to adequate food, water, or sanitation. UPA contributes to increased food security, nutrition and livelihoods in a combination of ways giving access to consumer markets; less need for packaging, storage and transportation of food; potential agricultural-related jobs and incomes; non-market access to food for poor consumers; availability of fresh, perishable food. In Abuja FCT, 40% of the populations in UPA are farmers, a reason why the agricultural quality of its groundwater which is used for irrigation begs for our attention. 33% of the fresh vegetables in the Abuja Federal Capital Territory (FCT) are produced in Abuja UPA. In order to assess groundwater for agro-industrial suitability the following were used: Physicochemical parameters (pH, Temperature, Electrical Conductivity), Sodium Adsorption Ratio SAR, Permeability Index PI, Magnesium Adsorption Ratio MAR, Percent Sodium %Na, Kelly¡¯s Ratio KR and Residual Sodium Carbonate RSC and the Wilcox diagram. pH ranged from, 4.8 - 7.9; EC, 13.4 - 1634 ¦ÌS/cm; Temperature, 26¡æ - 36.1¡æ and TDS, 17.42 - 1094.78 mg/L.SAR (0.1 > SAR < 2.1), Percent Sodium (7.11 > %Na < 100), KR (0 > KR < 0.68), RSC (-9.8 > RSC < 0.55), PI (13.9 > PI < 932.4), and MAR (0 > MAR < 80.1). Comparing these values to WHO and the Nigerian Water Quality guidelines, SAR, %Na, KR, RSC, values are 100% suitable, while PI, 96.81% suitable, and MAR 56.46% unsuitable respectively for irrigational purposes in agriculture. The quality classifications of irrigation water based on the values: Sodium Adsorption Ratio SAR, Wilcox, Kelley Ratio KR, Residual Sodium Carbonate RSC, Permeability Index PI and Percent Sodium %Na; indicate that groundwater of Abuja FCT is suitable for irrigation purpose on all soil types and that the groundwater will not degrade the soil. However, United States Soil Salinity USSL Index of Abuja FCT groundwater fall in ¡°very low to high salinity¡± and ¡°low sodium hazard zone¡± and Magnesium Adsorption Ratio MAR indicates half of the groundwater as ¡°not suitable¡±. Hence the groundwater in Abuja FCT should be used only on soils that are well drained.
