Air sumur di Kelurahan Tarus diduga telah terkontaminasi nitrit dan kadmium yang berasal dari pemakaian secara berlebihan pupuk SP-36 dan Urea. Oleh karena itu, penelitian ini telah dilaksanakan untuk membandingkan konsentrasi kontaminan nitrit dan kadmium dalam air sumur di daerah persawahan dan pemukiman dengan ambang baku mutu air baku air minum dan memprediksi besarnya risiko dari kontaminan terhadap kesehatan manusia. Penelitian deskriptif eksperimental ini menggunakan maing-masing 10 sampel air sumur dari daerah persawahan dan pemukiman. Kadar nitrit dan kadmium dianalisis dengan metode spektrofotometri dan spektrofotometri serapan atom. Baku mutu air minum dan air baku air minum berdasarkan PP 82 tahun 2001 dan PerMenKes 492 tahun 2010. Prediksi risiko terhadap kesehatan manusia dilakukan berdasarkan metode analisis risiko Public Health Assessment. Hasil penelitian menunjukkan bahwa di daerah persawahan dan permukiman berturut-turut terdapat tiga dan lima sumur yang mengandung nitrit namun kandungan tersebut masih berada di bawah nilai baku mutu air baku air minum. Sedangkan untuk kadmium, terdapat berturut-turut delapan dan tujuh sumur di daerah persawahan dan permukiman kandungannya berada di atas nilai baku mutu air baku air minum. Analisis risiko menunjukkan bahwa nitrit di persawahan dan pemukiman tidak berisiko terhadap kesehatan, sedangkan kadmium persawahan dan pemukiman yang berisiko sebanyak 14 sampel untuk durasi waktu 30 tahun, 12 sampel untuk 20 tahun, 10 sampel untuk 10 tahun dan tiga sampel untuk lima tahun. Karena itu diharapkan adanya pengurangan volume konsumsi air sumur yang berisiko, dan penanganan air tanah yang tercemar serta pengurangan pemakaian pupuk anorganik.
