Prep: In a large bowl, mix together the pork, green onions, garlic powder, water chestnuts, garlic, carrots, soy sauce, salt, and pepper. Scoop 1 tablespoon of the meat mixture onto 1 of the spring roll wrappers. Fold the bottom of the wrapper over the filling and continue to roll tightly into a log. To make it easy - do not overfill with the meat as it will be hard to close and possibly break during cooking. To seal the wrapper brush water around the edges of the wrapper, you can use your finger. Repeat this step until all wrappers have been filled then cut each lumpia roll into 3 inch lengths.
