Teluk Parepare di Sulawesi Selatan merupakan kawasan dengan aktivitas pelabuhan penumpang dan kargo, serta perikanan yang produktif. Aktifitas ini berdampak terhadap ekologi di perairan tersebut. Pesisir dan laut secara ekologi memiliki fungsi penting bagi kehidupan manusia. Salah satunya fungsi siklus biogeokimia dari buangan limbah yang masuk ke perairan tersebut. Akan tetapi, kebermanfaatan ini hendaknya tidak melebihi kapasitas ekologinya dalam menerima suatu jumlah limbah. Jika berlebih, maka akan terjadi kerusakan lingkungan dan kesehatan yang sulit ditoleransi. Kondisi ini mempersulit perairan tersebut untuk mewujudkan pembangunan berkelanjutan dan berkesesuaian dengan lingkungan. Penelitian ini bertujuan menganalisis sebaran spasial parameter kualitas air laut dan indeks pencemaran di perairan Teluk Parepare, serta sebagai upaya membantu pemerintah setempat melakukan pengawasan dan pengendalian pencemaran di perairan tersebut. Penelitian ini memanfaatkan hasil pengukuran in situ enam parameter (suhu, salinitas, pH, ammonia, timbal dan tembaga) di 28 stasiun pengamatan. Parameter tersebut mencakup baku mutu peruntukkan wilayah pelabuhan dan mengingat di kawasan tersebut terdapat juga aktivitas kilang minyak. Sebaran spasial parameter kualitas perairan merupakan hasil interpolasi dengan metode Inverse Distance Weighted (IDW) dari hasil pengukuran lapangan dan dihitung indeks pencemarannya. Hasil menunjukkan sebaran suhu, salinitas, ammonia, dan pH terlarut berkesesuaian dengan baku mutu, sedangkan konsentrasi timbal dan tembaga (logam berat) berada di atas baku mutu. Indeks pencemaran (IP) menghasilkan nilai antara 1,69–38,66. Nilai IP diklasifikasikan menjadi indeks cemar ringan di 14 stasiun pengamatan dan sebaran cemar ringan dominan di Teluk Parepare bagian dalam. Indeks cemar sedang terdapat di 12 stasiun pengamatan dan sebarannya di Teluk Parepare bagian luar, sedangkan cemar berat terdapat di 2 stasiun dan sebarannya di sekitar pesisir Kota Parepare. Kondisi ini menunjukkan bahwa parameter logam berat (seperti timbal dan tembaga) telah melebihi baku mutu dan berkaitan dengan berbagai kegiatan pelabuhan, serta perkapalan di sekitar perairan Teluk Parepare.
