waterWithout a doubt, clean water is considered by most people to be a fundamental measure of environmental health. We rely on surface water and groundwater for our drinking water supplies, for irrigation of crops, for industrial processes, and for outdoor recreation. Moreover, clean waters, whether they be free-flowing streams and rivers or serene ponds and lakes, have always been visited and admired for their natural beauty. Monitoring and protecting the health of surface water and groundwater resources has generally been at the forefront of environmental laws and regulations at the federal, state, and local level.
