TRSPA SWP Surface Water Vulnerable Scoring Areas

An area within an intake protection zone (IPZ-1, IPZ-2, and excluding IPZ-3) that has a vulnerability score.

Entity Name: SW VSA Surface Water

Table Name: SW_VSA_SURFACE_WATER_FT

A feature representing a vulnerable scoring area (VSA) that affects Surface Water. A vulnerable score is a number, between 0.1 and 10, representing how easily a well or intake can become polluted with a contaminant. The higher the score, the greater the contamination risk. Both zones and scores are important to determine how the plan treats your proposed activity (i.e., landfill site). Shows how susceptible a drinking water source is to contamination. In general, WHPA and IPZ that score 8 and above are very vulnerable and certain activities will be prohibited or required to be managed more effectively. 0 - 3.9: water sources in this area are least vulnerable to contamination. 4 - 7.9: water sources in this area are less vulnerable to contamination. 8 - 10: water sources in this area are vulnerable to contamination.
