4.4.1 Diversion of effluent
In some circumstances it may be possible to divert sewage effluent away from a water body in order to reduce nutrient loads. This was achieved at Lake Washington, near Seattle, USA, which is close to the sea. Lake Washington is surrounded by Seattle and its suburbs, and in 1955 a cyanobacterium, Oscitilloria rubescens, became dominant in the lake. The lake was receiving sewage effluent from about 70 000 people; this input represented about 56% of the total phosphorus load to the lake.

7 Inequalities
In this course, there have been three occasions when checks have been made to see whether the result is greater than or less than some other value. The first case was in calculating the BMI and determining whether the person was overweight or underweight; the second case was in determining whether a person was walking or running from his footprints; and the third case was in checking whether a phone had been used for more than 30 minutes. Checking whether values are greater than or less than

3.5 Several calculations and using brackets
Sometimes you may want to make several calculations in succession, and the order in which the calculations are performed may or may not be significant. For example, if you want to add 12 + 7 + 13, it makes no difference which of these two processes you adopt:
add the 12 and 7 first, to give 19, and then the 13, to give 32;
add the 7 and 13 first, to give 20, and then add this to 12 to give 32 again.

2.2.3 The effect of people and places
The footprints in the above Carbon Trust and National Statistics studies are for an average UK citizen. But footprints vary for different individuals and households. For example, another study showed that, on average, people aged 50 to 64 have heavier footprints than all other UK age groups, mainly due to their high spending on car and air travel, eating and drinking, and medical and financial services (Haq et al., 2007, p. 7).
The National Statistics study showed that the UK regions wi
