Bring water to a boil in a large saucepan. Add wild rice, cover, reduce heat to medium-low and cook at a lively simmer until the grains are tender and starting to split, 45 to 55 minutes. Drain in a fine sieve.
Shortly before the wild rice is ready, heat oil in a large nonstick skillet over medium-high heat. Add onion and cook, stirring often, until softened, 2 to 3 minutes. Add bell pepper, garlic and cumin; cook, stirring, for 1 minute. Add apricots, orange juice, salt and pepper; simmer until the apricots have plumped and the liquid has reduced slightly, 1 to 2 minutes. Stir in the wild rice. Remove from the heat and stir in scallion greens. Serve topped with chopped pistachios.
