You are a consultant helping an airport design ways of meeting state-mandated standards for the disposal of de-icing chemicals that run off of airport runways during the winter and into surface water and ground water. One of the other consultants working with you has written this letter to the airport authority asking about the runoff water. It is pretty badly written, so you need to rewrite it.

Cleanwater Consulting Services P 314 Perry Pike, Farlough, IA 31513   May 15, 2018 Ms. Tanya Bushman Cedar Point County Airport Cedar Point, IA 31502 Dear Tanya: The de-icing runoff is going into farm ponds beside the airport. Concerning the current and future use of the farm ponds, we need some information about projected time period that the ponds will be used to collect water from the runways as well as whether the new owners will allow use of the acreage for that purpose for an extended time period. We're thinking the water could be discharged to Lincoln Creek if the discharge meets water quality standards. If only elevated heavy metals are present, the contaminated water should be routed to the farm ponds, though. If an elevated level of nitrate is present, the water can't go into the ponds but can be applied on the acreage above the runways, away from the farm ponds, so it seeps into the ground. In addition, we're wondering whether the pond acreage will be sufficient to handle all the future water that might run off at this location. Please respond in a timely fashion. Sincerely,
