The projects have multiple purposes. One has an outdoor classroom in the center a series of vegetated bays that hold rainwater and manage

The LCR requires water systems to monitor the drinking water they provide and control for corrosion. Because lead can get into drinking water at various points throughout the system, as
Harmful Algal Outbreaks and Drinking Water
Freshwater Harmful Algal Blooms happen most often where there are high levels of nutrients like nitrogen or phosphorus present in warm, still waters like lakes, ponds, or reservoirs. They can also occur in rivers, especially during summer months. Aquatic ecosystems need nutrients to thrive but fertilizer runoff from agriculture, sewage and industrial discharges, and urban stormwater have added an excessive of nutrients into many of our nation’s bays, lakes and rivers.
