HeinOnline is a government, politics and law database that includes the Federal Register Library, U.S. Congressional Documents, Code of Federal Regulations, National Survey of State Laws, U.S. Federal Legislative History, and U.S. Federal Agency Documents, Decision, and Appeals.

You can use Google search commands to search just governmental websites to find information or the text of laws. The search illustrated below will give me results about the Clean Water Act from sites with the .gov domain. If you are looking for state laws, just replace the .gov with the state’s domain. For example, if I was interested in a Massachusetts Law, I would add site:mass.gov to my search.
