Jim Lenhart on waterway pollution, fish brain function, and total maximum daily load targets for stormwater pollution

Our guest for this episode is Jim Lenhart, who Jeremy calls the “Godfather” of stormwater. Jim is based in Portland, Oregon, USA and is the Chief Technology Officer for Stormwater for Contech Engineered Solutions. We talk about a range of topics, including the history of stormwater management in USA, the impacts of excessive sediment and phosphorus in lakes and waterways, the link between fish mental function and heavy metal contamination, total maximum daily load targets, and endocrine disruptor and phthalate pollution in waterways.
