Penelitian tentang potensi mataair dilakukan di Pulau Wamar Kabupaten Kepulauan Aru Propinsi Maluku. Adapun tujuan penelitian ini adalah: 1) mengkaji potensi mataair yang ada di daerah penelitian sebagai sumber air bersih; 2) menghitung kebutuhan air bersih didaerah penelitian; 3) menyusun suatu strategi pengelolaan lingkungan kaitannya dengan penggunaan mataair sebagai sumber air bersih di daerah penelitian. Metode penelitian yang digunakan adalah metode survei lapangan dan analisis di laboratorium. Data yang dikumpulkan adalah data primer terdiri dari kebutuhan air di daerah penelitian, debit mataair, dan kualitas air meliputi parameter fisik, kimia, dan biologi (Warna, Rasa dan Bau, Kekeruhan, Temperatur, pH, Fe, CaCo3, Mn, NO-2, NO-3, Cl-, SO4-2, E. Coli). Data sekunder berupa curah hujan, geologi, temperatur udara, kependudukan, penggunaan lahan, juga letak, luas dan batas wilayah. Hasil penelitian menunjukan di daerah penelitian terdapat beberapa mataair, dua diantaranya adalah mataair Gomu dan mataair Nam. Pada saat pengukuran di lapangan bulan Ferbuari 2010 debit mataair Gomu terukur sebesar 10,17 l/det dan mataair Nam sebesar 8,13 l/det, sehingga total debit kedua mataair 18,3 l/det. Debit kedua mataair dapat memenuhi 77% kebutuhan air bersih penduduk di daerah penelitian pada tahun 2020, dengan prediksi jumlah penduduk sebanyak 26.774 jiwa. Berdasarkan hasil analisis laboratorium kualitas mataair Gomu Warna (1,14 TCU), Rasa (Tidak berasa), Bau (Tidak berbau), Kekeruhan (6,42 NTU), Temperatur (25 ºC), pH (6,42), Fe (0,1 mg/L), CaCO3 (116 mg/L), Mn (0,110 mg/L), NO2 - (0,176 mg/L), NO3- (0,64 mg/L), Cl- (6,0 mg/L), SO4-2 (8,0 mg/L) dengan kandungan Coliform Total 7 MPN/100 ml. Mataair Nam Warna(1,10 TCU), Rasa (Tidak berasa), Bau (Tidak berbau), kekeruhan (3,67 NTU), Temperatur (25 ºC), pH (3,67), Fe (=LOD mg/L), CaCO3 (200 mg/L), Mn (0,011 mg/L), NO2- (0,174 mg/L), NO3- (=LOD mg/L), Cl- (12,0 mg/L), SO4-2 (8,28 mg/L) dengan kandungan Coliform Total 1100 MPN/100 ml.

Research on the potential of spring water carried on the Wamar Island of Aru Islands Regency, Maluku Province. The purpose of this research are: 1) assess the potential of existing springs in the research area as resource of clean water, 2) calculate the water needs of the research area, 3) to study environmental management strategies relating to the use of springs as resource of clean water in research area. The method used is the method of field survey and analysis in the laboratory. The data collected is the primary data consist of water demand in the research area, spring flow and water quality include physical parameters, chemical, and biological (color, taste and odor, turbidity, temperature, pH, Fe, CaCO3, Mn, NO2-, NO3-, Cl-, SO4-2, E. Coli). Secondary data in the form of rainfall, geology, air temperature, population, land use, also the location, area and boundaries. The results showed that in the study area there are several springs, two of which are spring Gomu and spring Nam. At the time of field measurements in Ferbuari 2010 Gomu measured spring discharge of 10,17 l/s and spring Nam amounted to 8,13 l/s, so the total second spring discharge 18,3 l/s. Both spring discharge to meet water demand 77% of the population in the research area in 2020, with estimated population of 26.774 inhabitants. Based on the results of laboratory analysis of the quality of spring Gomu Color (1,14 TCU), Flavor (taste not), smell (no smell), turbidity (6,42 NTU), temperature (25 ºC), pH (6,42), Fe (0,1 mg/L), CaCO3 (116 mg/ L), Mn (0,110 mg/L), NO2- (0,176 mg/L), NO3- (0,64 mg/L), Cl- (6,0 mg/L), SO4-2 (8,0 mg/L) with the contents of 7 ml Total Coliform MPN/100. Nam spring colors (1,10 TCU), Flavor (No taste), smell (not smelly), turbidity (3,67 NTU), temperature (25 ºC), pH (3,67), Fe (= LOD mg/L), CaCO3 (200 mg/L), Mn (0,011 mg/L), NO2- (0,174 mg/L), NO3- (= LOD mg /L), Cl- (12 mg/L), SO4-2 (8,28 mg/L) with the content of 1100 Total Coliform MPN/100 ml.
