DYER | Cleaner stormwater was the topic of a workshop this week attended by more than 100 Northwest Indiana builders and public officials.
Lake County Surveyor George Van Til said the seminar was intended to remind private construction companies and local government work site inspectors of basic strategies to reduce soil erosion and pollution from work sites.
Van Til said the lessons are timely because an improving economy probably will result in more construction this season.
The U.S. Clean Water Act mandates county and municipal governments enforce regulations requiring contractors to use silt fences and mulching; check dams, sediment traps, erosion blankets and filter baskets; and seed bare soil in drainage areas to prevent sediment from entering local waterways.
Contractors also were told to avoid contaminating waterways with wastewater used to wash concrete off equipment.
