Identifikasi dilakukan berdasarkan parameter temperatur, konduktivitas listrik, pH, Total Dissolved Solid (TDS), kandungan logam berat (Hg dan Pb), dan kandungan fosfat. Analisis tingkat pencemaran menggunakan metode Indeks Pencemaran air (IP). Berdasarkan nilai IP, air sungai Batang Lembang di Kota Solok dikategorikan tercemar ringan dengan nilai IP rata-rata sebesar 1,124. Hasil pengukuran menunjukkan bahwa diantara tujuh parameter hanya parameter fosfat yang telah melebihi standar batas baku mutu air sungai kelas II menurut Peraturan Pemerintah Nomor 82 Tahun 2001. Nilai rata-rata temperatur air di sungai Batang Lembang adalah 31°C. Nilai ini lebih rendah dari temperatur udara di sekitarnya yaitu 30°C.
