#TITLE: 
State of Hawaii, Department of Health, Clean Water Branch
State-wide Water Quality Sampling Dataset 1973-1998

#ABSTRACT: 
The Monitoring Section of the State of Hawaii, Department of Health, 
Clean Water Branch collects water quality data at over 300 coastal
locations state-wide using well-established instruments and methodologies.  
This dataset spans 1973-1998.

#PURPOSE:  
The Clean Water Branch (CWB) protects the public health of residents and
tourists who enjoy recreating in and around Hawaii’s coastal and inland water
resources. The CWB also protects and restores inland and coastal waters for
marine life and wildlife. This is accomplished through statewide coastal water
surveillance and watershed-based environmental management through a
combination of permit issuance, monitoring, enforcement, sponsorship of
polluted runoff control projects, and public education.
