There are ~40 motorway outfalls into the upper reaches of the River Douglas catchment in Lancashire. Together, they drain 157 hectares of motorway surface into the River. That’s about 470 tonnes of toxic sediment washed into the River every year. #StormwaterPollution

Applications of road salt mobilise toxic metals that are lurking in the drainage system. They are washed into rivers & streams as the snow melts and they are toxic to fish & aquatic insects #StormwaterPollution
Something a bit different for me today, talking about dirty water from construction sites. Another source of #StormwaterPollution that is often overlooked. Well done to RVT Group for bringing this event together 👍🏻
Don’t be fooled by the beauty. Snowmelt causes #StormwaterPollution too 🌨️
Highway runoff causes horrific pollution of rivers every time it rains. This outfall in Lancashire discharges toxic, hazardous substances into the River Lostock, causing it to fail to meet env. standards. These substances are toxic to the invertebrates living in the river. #StormwaterPollution
