Description: This dataset measures hazardous waste facility proximity to residential populations, weighting distances inversely (1/distance) to quantify environmental exposure risks. Each block's score sums the proximity influence of nearby facilities, while block group scores aggregate these based on population distribution. Facilities within 5 km contribute to the score, with adjustments for unpopulated areas. If no facility is within range, the nearest facility's inverse distance is used. GEOID', (integer): Unique identifier for each block group'County_Name', (string): Name of Washington State county'State', (string): State identifier'Population', (integer): Estimated total population of the block group'HazWaste_Proximity_Percentile_Rank', (float): Percentile ranking of block group for hazardous waste facility proximity 'HazWaste_Proximity_Score' (integer): WTN standardized score for hazardous waste facility proximity
