Rather than being absorbed into the ground or becoming surface run-off, the rainwater is directed using sloped surfaces, channels, and gravity into the storage location. However, opponents of the dry storage method have raised concerns about the dangers of transporting volatile nuclear waste for dry storage and the radioactivity levels that workers are exposed to, as well as the risk of canisters opening and leaking content. Studies find retention ponds decrease several pollutants by 30% to 80%: The ability to collect and bind harmful contaminants in sediments prevents them from reaching streams and rivers, further damaging the ecosystems. Advantages and disadvantages are examined Based on pro maintenance company use from 1978. The ecosystem wetlands provide for plants and animals is just the beginning of the reasons wetlands are protected by law. Simple rainwater collection systems worldwide use roofs and other slanted surfaces and even an upturned umbrella design to collect rainfall efficiently for later use. Because they detain water for a brief time before allowing it to flow out, dry ponds are also called detention ponds. This is because rainwater often contains atmospheric pollutants and contamination that have been washed into the collected water. She grew up in a log house in the hills of a small town in Upstate New York. For this reason, much of the USs used fuel, over 70,000 tons, is currently stored in interim storage pools and casks at nuclear power plants throughout the country.
