Taman Wisata Alam Telogo Warno dan Telogo Pengilon memiliki manfaat penting dalam bidang pariwisata dan pertanian. Pemanfaatan yang berlebihan pada kawasan konservasi dapat menyebabkan perubahan kualitas perairan serta dampak negatif terhadap fungsi ekosistem kawasan perairan Taman Wisata Alam Telogo Warno dan Telogo Pengilon. Oleh karena itu perlu dilakukan penelitian awal tentang kualitas fisik, kimia, dan biologis kawasan perairan Taman Wisata Alam Telogo Warno dan Telogo Pengilon. Penelitian ini bertujuan untuk mengetahui (1) kualitas fisik, kimia dan biologis kawasan perairan, dan (2) tingkat cemar kawasan perairan. Penentuan titik sampel ditentukan dengan menggunakan metode Uniform Sistematik Distribution sehingga diperoleh 10 (sepuluh) titik dengan jarak antar titik 100mx100m. Parameter untuk menentukan kualitas kawasan perairannya antara lain suhu, TDS, pH, salinitas, DO, BOD, COD, Fosfat, amoniak, dan total Coliform. Analisis data dilakukan dengan menggunakan metode Indeks Pencemaran (IP) sesuai dengan pedoman Lampiran II Keputusan Menteri Negara Lingkungan Hidup Nomor 115 Tahun 2003 tentang Pedoman Penentuan Status Mutu Air. Telogo Warno memiliki nilai pH rendah atau asam dengan nilai 2,33 dan COD yang tinggi yaitu 51,86 mg/L dan melebihi baku mutu air kelas II, sedangkan Telogo Pengilon memiliki nilai COD 59,62 mg/L dan total Colliform 56,00 individu/100ml yang tinggi atau melebihi baku mutu air kelas II. Sementara untuk nilai TDS, suhu, DO, Fosfat, dan kandungan amonia pada perairan Telogo Warno dan Telogo Pengilon dalam keadaan normal atau tidak melebihi baku mutu kelas II. Beberapa parameter yang melebihi baku mutu air tersebut mengakibatkan kawasan perairan Telogo Warno dan Telogo Pengilon pada tanggal 27 April 2014 memiliki tingkat cemar perairan yang ringan dengan nilai Indeks Pencemaran (IP) masing-masing mencapai 2, 69 dan 2,10.

Warno Lake and Pengilon Lake Nature Parks have some important benefits in the field of tourism and agriculture. Unfortunately, an excessive utilization in that conservation areas can cause changes in water quality as well as negative impacts on the ecological function of Warno Lake and Pengilon Lake Nature Park aquatic ecosystems. Therefore, it is essential to do the first study of physical, chemical, and biological quality in the water area of Warno Lake and Pengilon Lake Nature Parks. This study aimed to determine (1) physical, chemical and biological quality in the water area, and (2) to know pollution level of water area. Sample points were determined using the Uniform Systematic Distribution method, thus obtained ten (10) points in which the distance between each point was 100mx100m. The parameters which were used to determine the quality of water area were: temperature, TDS, pH, salinity, DO, BOD, COD, phosphates, ammonia, and Coliform total. Data analysis was then performed using the method of Pollution Index (IP) in accordance with the gudelines of annex II to the decree of the Minister of Environment number 115 of 2003 on Guidelines for Determination of Water Quality Status. Warno Lake had a low pH or acid which only reached 2.33 and a high COD which reached 51.86mg/L and it exceeded the water quality, while Telogo Pengilon’s COD value was 59.62 mg/L and its Coliform total was 56.00 individu/100ml high or exceeded the water quality. However, the value of TDS, temperature, DO, phosphate, and ammonia content in the water of Telogo Pengilon and TelogoWarno were classified as under normal circumtances and did not exceed the standards. Some of the parameters that exceeded the water quality standards resulting the water area of Warno Lake and Pengilon Lake on 27 April 2014 have a light level of water pollution level with the values of its Pollution Index (IP) reached 2, 69 and 2.10.
