Flood Frequency – the Science T = (N + 1) / M where T is the recurrence interval in years, N is the number of years of record, and M is the rank of the event of interest. T is also 1/P, where P is the probability, in percent, that an event of a particular size will occur in the next year.

Erosion Is the prospective property likely to lose ground?
A few simple precautions can save enormous headaches later • Check the flood insurance maps • Ask the neighbors • Look for signs of stream bank erosion
Environmental Hazards • Radon • Water Supplies • Lead in Soils
Radon is a natural component of soils and is highly variable from region to region and house to house
Actions to Take • Each house needs to be tested separately • Remediation is inexpensive and effective • Better to lose a sale than be accused of disguising a problem
Drinking Water Problems • Copper (Cu) in new construction • Lead (Pb) in old construction
Hamilton Co. water comes from 2 sources: Miller & Bolton. Butler Co. gets some water from Mason.

About Lead and Your Drinking Water There is no detectable lead in our drinking water as it leaves the treatment plants. It is possible that lead levels in your home may be high because of your home's pipes and plumbing fixtures. Infants and young children are more vulnerable to lead in drinking water. If you are concerned about high lead levels, have your water tested at no charge by Greater Cincinnati Water Works by calling 513 -591 -7700. Flushing your tap for up to two minutes before using the water and using only cold water for cooking are also helpful. http: //www. cincinnati-oh. gov/pages/-297 -/
The major route of lead poisoning is actually soil and paint • Roadside soils have high Pb • Soils around older homes tend to have high Pb • Dust on window sills can be very high in Pb
Roadside soils (and those near houses with Pb paint) can have dangerous levels of Pb at the surface.
What to do? § As a developer, soil testing for Pb is cheap and can save major headaches later. § As a homeowner with small children, it can be a lifesaver. § The cost of environmental inspection is not trivial, but is very small in proportion to the risk.
